Task: Question Answering
Input (English): Context: The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., Vilnius District Municipality is one of 60 municipalities in Lithuania. It surrounds the capital city of Vilnius on 3 sides, while the rest borders the Trakai District Municipality., 
In Japanese, haiku are traditionally printed in a single vertical line while haiku in English often appear in three lines to parallel the three phrases of Japanese haiku. , Watchful waiting (also watch and wait or WAW) is an approach to a medical problem in which time is allowed to pass before medical intervention or therapy is used. During this time, repeated testing may be performed., The European Capital of Culture is a city designated by the European Union for a period of one calendar year during which it organises a series of cultural events with a strong European dimension., Leukemia, also spelled leukaemia, is a group of cancers that usually begin in the bone marrow and result in high numbers of abnormal white blood cells. These white blood cells are not fully developed and are called "blasts" or "leukemia cells". Symptoms may include bleeding and bruising problems, feeling tired, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically made by blood tests or bone marrow biopsy.
The exact cause of leukemia is unknown. Different kinds of leukemia are believed to have different causes. Both inherited and environmental (non-inherited) factors are believed to be involved. Risk factors include smoking, ionizing radiation, some chemicals (such as benzene), prior chemotherapy, and Down syndrome. People with a family history of leukemia are also at higher risk. There are four main types of leukemia  acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML)  as well as a number of less common types. Leukemias and lymphomas both belong to a broader group of tumors that affect the blood, bone marrow, and lymphoid system, known as tumors of the hematopoietic and lymphoid tissues.
Treatment may involve some combination of chemotherapy, radiation therapy, targeted therapy, and bone marrow transplant, in addition to supportive care and palliative care as needed. Certain types of leukemia may be managed with watchful waiting. The success of treatment depends on the type of leukemia and the age of the person. Outcomes have improved in the developed world. The average five-year survival rate is 57% in the United States. In children under 15, the five-year survival rate is greater than 60 to 85%, depending on the type of leukemia. In children with acute leukemia who are cancer-free after five years, the cancer is unlikely to return.
In 2012, leukemia developed in 352,000 people globally and caused 265,000 deaths. It is the most common type of cancer in children, with three quarters of leukemia cases in children being the acute lymphoblastic type. However, about 90% of all leukemias are diagnosed in adults, with AML and CLL being most common in adults. It occurs more commonly in the developed world., Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges (the Sudetes and Carpathian Mountains) in the south. Bordered by Germany to the west; the Czech Republic and Slovakia to the south; Ukraine and Belarus to the east; and the Baltic Sea, Kaliningrad Oblast (a Russian exclave) and Lithuania to the north. The total area of Poland is , making it the 69th largest country in the world and the 9th largest in Europe. With a population of over 38.5 million people, Poland is the 34th most populous country in the world, the 8th most populous country in Europe and the sixth most populous member of the European Union. Poland is a unitary state divided into 16 administrative subdivisions, and its capital and largest city is Warsaw. Other metropolises include Kraków, Wrocaw, Pozna, Gdask and Szczecin., Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal white blood cells that build up in the bone marrow and interfere with the production of normal blood cells. AML is the most common acute leukemia affecting adults, and its incidence increases with age. Although AML is a relatively rare disease, accounting for roughly 1.2% of cancer deaths in the United States, its incidence is expected to increase as the population ages., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., Kaliningrad Oblast ("Kaliningradskaya oblast") is a federal subject of the Russian Federation that is located on the coast of the Baltic Sea. As an oblast, its constitutional status is equal to each of the other 84 federal subjects. Its administrative center is the city of Kaliningrad, formerly known as Königsberg. It is the only Baltic port in the Russian Federation that remains ice-free in winter. According to the 2010 census, it had a population of 941,873., An official language is a language that is given a special legal status in a particular country, state, or other jurisdiction. Typically a country's official language refers to the language used within government (e.g., courts, parliament, administration). Since "the means of expression of a people cannot be changed by any law", the term "official language" does not typically refer to the language used by a people or country, but by its government., The United Nations Educational, Scientific and Cultural Organization (UNESCO) is a specialized agency of the United Nations (UN) based in Paris. Its declared purpose is to contribute to peace and security by promoting international collaboration through educational, scientific, and cultural reforms in order to increase universal respect for justice, the rule of law, and human rights along with fundamental freedom proclaimed in the United Nations Charter.
It is the heir of the League of Nations' International Committee on Intellectual Cooperation., Kaunas (also see other names) is the second-largest city in Lithuania and has historically been a leading centre of Lithuanian economic, academic, and cultural life. Kaunas was the biggest city and the centre of a county in Trakai Municipality of the Grand Duchy of Lithuania since 1413. In the Russian Empire it was the capital of the Kaunas Governorate from 1843 to 1915. It became the only temporary capital city in Europe during the interwar period. Now it is the capital of Kaunas County, the seat of the Kaunas city municipality and the Kaunas District Municipality. It is also the seat of the Roman Catholic Archdiocese of Kaunas. Kaunas is located at the confluence of the two largest Lithuanian rivers, the Nemunas and the Neris, and near the Kaunas Reservoir, the largest body of water entirely in Lithuania., Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, others being hormonal therapy and cytotoxic chemotherapy. As a form of molecular medicine, targeted therapy blocks the growth of cancer cells by interfering with specific targeted molecules needed for carcinogenesis and tumor growth, rather than by simply interfering with all rapidly dividing cells (e.g. with traditional chemotherapy). Because most agents for targeted therapy are biopharmaceuticals, the term "biologic therapy" is sometimes synonymous with "targeted therapy" when used in the context of cancer therapy (and thus distinguished from chemotherapy, that is, cytotoxic therapy). However, the modalities can be combined; antibody-drug conjugates combine biologic and cytotoxic mechanisms into one targeted therapy., Lithuanian ("") is the official state language of Lithuania and is recognized as one of the official languages of the European Union. There are about 2.9 million native Lithuanian speakers in Lithuania and about 200,000 abroad. Lithuanian is a Baltic language, related to Latvian. It is written in a Latin alphabet. Lithuanian is often said to be the most conservative living Indo-European language, retaining many features of Proto-Indo-European now lost in other Indo-European languages., Arnas Matelis (9 April 1961, Kaunas) is an acclaimed Lithuanian documentary film director. From 1979 till 1983 Arnas Matelis studied Mathematics at Vilnius University and later in 1989 graduated from the Lithuanian Music Academy. In 1992, he established one of the first independent film production companies in Lithuania, "Nominum". In 2006 Matelis became a full member of European Film Academy with the right to vote., Belarus ( lat. ', ), officially the Republic of Belarus, formerly known by its Russian name Byelorussia (though this name is no longer used in Belarus itself, even in Russian language), is a landlocked country in Eastern Europe bordered by Russia to the northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Its capital and most populous city is Minsk. Over 40% of its is forested. Its strongest economic sectors are service industries and manufacturing. Until the 20th century, different states at various times controlled the lands of modern-day Belarus, including the Principality of Polotsk (11th to 14th centuries), the Grand Duchy of Lithuania, the PolishLithuanian Commonwealth, and the Russian Empire., Acute lymphoblastic leukemia, also known as acute lymphocytic leukemia or acute lymphoid leukemia (ALL), is an acute form of leukemia, or cancer of the white blood cells, characterized by the overproduction and accumulation of cancerous, immature white blood cells, known as lymphoblasts. In persons with ALL, lymphoblasts are overproduced in the bone marrow and continuously multiply, causing damage and death by inhibiting the production of normal cells (such as red and white blood cells and platelets) in the bone marrow and by spreading (infiltrating) to other organs. ALL is most common in childhood, with a peak incidence at 25 years of age and another peak in old age., Chemotherapy (often abbreviated to chemo and sometimes CTX or CTx) is a category of cancer treatment that uses one or more anti-cancer drugs (chemotherapeutic agents) as part of a standardized chemotherapy regimen. Chemotherapy may be given with a curative intent (which almost always involves combinations of drugs), or it may aim to prolong life or to reduce symptoms (palliative chemotherapy). Chemotherapy is one of the major categories of medical oncology (the medical discipline specifically devoted to pharmacotherapy for cancer)., Vilnius University (other names exist) is the oldest university in the Baltic states and one of the oldest in Northern Europe. It is the largest university in Lithuania., Northern Europe is the northern part or region of Europe. Although no definitive borders or definition exists for the term, geographically, Northern Europe may be considered to consist approximately of all of Europe above the 52nd parallel north; which includes (from west to east) most or all of: Iceland, the Republic of Ireland, the Isle of Man, the United Kingdom, the Faroe Islands, the Netherlands, northern Germany, Denmark, Norway, Sweden, northern Poland, Finland, Estonia, Latvia, Lithuania and northwest Russia. However, narrower definitions may also be used based on other geographical factors, such as climate and ecology. Greenland, geographically a part of North America, is politically a part of the Kingdom of Denmark, and may be included depending on the definition., Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Not all tumors are cancerous; benign tumors do not spread to other parts of the body. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss and a change in bowel movements. While these symptoms may indicate cancer, they may have other causes. Over 100 types of cancers affect humans.
Tobacco use is the cause of about 22% of cancer deaths. Another 10% is due to obesity, poor diet, lack of physical activity and drinking alcohol. Other factors include certain infections, exposure to ionizing radiation and environmental pollutants. In the developing world nearly 20% of cancers are due to infections such as hepatitis B, hepatitis C and human papillomavirus (HPV). These factors act, at least partly, by changing the genes of a cell. Typically many genetic changes are required before cancer develops. Approximately 510% of cancers are due to inherited genetic defects from a person's parents. Cancer can be detected by certain signs and symptoms or screening tests. It is then typically further investigated by medical imaging and confirmed by biopsy.
Many cancers can be prevented by not smoking, maintaining a healthy weight, not drinking too much alcohol, eating plenty of vegetables, fruits and whole grains, vaccination against certain infectious diseases, not eating too much processed and red meat, and avoiding too much sunlight exposure. Early detection through screening is useful for cervical and colorectal cancer. The benefits of screening in breast cancer are controversial. Cancer is often treated with some combination of radiation therapy, surgery, chemotherapy, and targeted therapy. Pain and symptom management are an important part of care. Palliative care is particularly important in people with advanced disease. The chance of survival depends on the type of cancer and extent of disease at the start of treatment. In children under 15 at diagnosis the five-year survival rate in the developed world is on average 80%. For cancer in the United States the average five-year survival rate is 66%.
In 2012 about 14.1 million new cases of cancer occurred globally (not including skin cancer other than melanoma). It caused about 8.2 million deaths or 14.6% of human deaths. The most common types of cancer in males are lung cancer, prostate cancer, colorectal cancer and stomach cancer. In females, the most common types are breast cancer, colorectal cancer, lung cancer and cervical cancer. If skin cancer other than melanoma were included in total new cancers each year it would account for around 40% of cases. In children, acute lymphoblastic leukaemia and brain tumors are most common except in Africa where non-Hodgkin lymphoma occurs more often. In 2012, about 165,000 children under 15 years of age were diagnosed with cancer. The risk of cancer increases significantly with age and many cancers occur more commonly in developed countries. Rates are increasing as more people live to an old age and as lifestyle changes occur in the developing world. The financial costs of cancer were estimated at $1.16 trillion US dollars per year as of 2010.
Definitions.
Cancers are a large family of diseases that involve abnormal cell growth with the potential to invade or spread to other parts of the body. They form a subset of neoplasms. A neoplasm or tumor is a group of cells that have undergone unregulated growth and will often form a mass or lump, but may be distributed diffusely., Latvia, officially the Republic of Latvia, is a country in the Baltic region of Northern Europe, one of the three Baltic states. It is bordered by Estonia to the north, Lithuania to the south, Russia to the east, and Belarus to the southeast, as well as a maritime border to the west alongside Sweden. Latvia has 1,957,200 inhabitants and a territory of . The country has a temperate seasonal climate., Before Flying Back to Earth ( originally released in Lithuania as Prieš parskrendant  žem in 2005 ) is the first feature - length documentary film by the Lithuanian film director Arnas Matelis . In a lyrical , yet unsentimental fashion , it shows the lives of children hospitalized with leukemia in Vilnius Pediatric Hospital - the same place where Matelis ' daughter had battled and recovered from this disease some time before the start of production . The film is described as `` a poetic , unsentimental Lithuanian documentary about the resilience of ( the ) human spirit '' . Its laconic style and its formal simplicity have been likened to haiku by some critics . Before Flying Back to the Earth is the most highly acclaimed recent Lithuanian film and is considered one of the best documentary films of 2005 in the world ; it has been shown in numerous festivals . The film is in the Lithuanian language ., The Baltic states, also known as the Baltic countries, Baltic republics, Baltic nations, or simply, the Baltics, are the three countries in northern Europe on the eastern coast of the Baltic Sea: Estonia, Latvia and Lithuania. The Baltic states cooperate on a regional level in several intergovernmental organizations., Direct-to-video or straight-to-video (also known as direct-to-VHS, direct-to-DVD, direct-to-Blu-ray, direct-to-digital, etc.) refers to the release of a film to the public immediately on home video formats rather than a theatrical release or television broadcast. Because inferior sequels or prequels of larger-budget films may be released direct to video, references to direct-to-video releases are often pejorative. Direct-to-video release has also become profitable for independent filmmakers and smaller companies., A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a needle, or via fingerprick. Multiple tests for specific blood components (such as a glucose test or a cholesterol test) are often grouped together into one test panel called a blood panel or blood work. Blood tests are often used in health care to determine physiological and biochemical states, such as disease, mineral content, pharmaceutical drug effectiveness, and organ function. Typical clinical blood panels include a basic metabolic panel or a complete blood count. Blood tests are also used in drug tests to detect drug abuse. In some of the United States, a blood test is required before marriage; historically, this was previously true in more states., A film director is a person who directs the making of a film. Generally, a film director controls a film's artistic and dramatic aspects, and visualizes the script while guiding the technical crew and actors in the fulfillment of that vision. The director has a key role in choosing the cast members, production design, and the creative aspects of filmmaking. Under European Union law, the director is viewed as the author of the film., Linz  is the third-largest city of Austria and capital of the state of Upper Austria. It is located in the north centre of Austria, approximately south of the Czech border, on both sides of the River Danube. The population of the city is , and that of the Greater Linz conurbation is about 271,000. , Lymphoma is a group of blood cell tumors that develop from lymphocytes (a type of white blood cell). The name often refers to just the cancerous ones rather than all such tumors. Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired. The enlarged lymph nodes are usually painless. The sweats are most common at night.
There are dozens of subtypes of lymphomas. The two main categories of lymphomas are Hodgkin's lymphomas (HL) and the non-Hodgkin lymphomas (NHL). The World Health Organization (WHO) includes two other categories as types of lymphoma: multiple myeloma and immunoproliferative diseases. About 90% of lymphomas are non-Hodgkin lymphomas. Lymphomas and leukemias are a part of the broader group of tumors of the hematopoietic and lymphoid tissues.
Risk factors for Hodgkin lymphoma include infection with EpsteinBarr virus and a history of the disease in the family. Risk factors for common types of non-Hodgkin lymphomas include autoimmune diseases, HIV/AIDS, infection with human T-lymphotropic virus, immunosuppressant medications, and some pesticides. Eating large amounts of red meat and tobacco smoking may also increase the risk. Diagnosis, if enlarged lymph nodes are present, is usually by lymph node biopsy. Blood, urine, and bone marrow testing may also be useful in the diagnosis. Medical imaging may then be done to determine if and where the cancer has spread. Lymphoma most often spreads to the lungs, liver, and/or brain.
Treatment may involve one or more of the following: chemotherapy, radiation therapy, targeted therapy, and surgery. In some non-Hodgkin lymphomas, an increased amount of protein produced by the lymphoma cells causes the blood to become so thick that plasmapheresis is performed to remove the protein. Watchful waiting may be appropriate for certain types. The outcome depends on the subtype with some being curable and treatment prolonging survival in most. The five-year survival rate in the United States for all Hodgkin lymphoma subtypes is 85%, while that for non-Hodgkin lymphomas is 69%. Worldwide, lymphomas developed in 566,000 people in 2012 and caused 305,000 deaths. They make up 34% of all cancers, making them as a group the seventh-most common form. In children, they are the third-most common cancer. They occur more often in the developed world than the developing world., Vilnius (see also other names) is the capital of Lithuania and its largest city, with a population of 542,664 . Vilnius is located in the southeast part of Lithuania and is the second largest city in the Baltic states. Vilnius is the seat of the main government institutions of Lithuania as well as of the Vilnius District Municipality. Vilnius is classified as a Gamma global city according to GaWC studies, and is known for the architecture in its Old Town, declared a UNESCO World Heritage Site in 1994. Its Jewish influence until the 20th century has led to it being described as the "Jerusalem of Lithuania" and Napoleon named it "the Jerusalem of the North" as he was passing through in 1812. In 2009, Vilnius was the European Capital of Culture, together with the Austrian city of Linz., Down syndrome (DS or DNS), also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is typically associated with physical growth delays, characteristic facial features and mild to moderate intellectual disability. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental ability of an 8- or 9-year-old child, but this can vary widely.
The parents of the affected individual are typically genetically normal. The extra chromosome occurs by chance. The possibility increases from less than 0.1% in 20-year-old mothers to 3% in those age 45. There is no known behavioral activity or environmental factor that changes the possibility. Down syndrome can be identified during pregnancy by prenatal screening followed by diagnostic testing or after birth by direct observation and genetic testing. Since the introduction of screening, pregnancies with the diagnosis are often terminated. Regular screening for health problems common in Down syndrome is recommended throughout the person's life.
There is no cure for Down syndrome. Education and proper care have been shown to improve quality of life. Some children with Down syndrome are educated in typical school classes, while others require more specialized education. Some individuals with Down syndrome graduate from high school and a few attend post-secondary education. In adulthood, about 20% in the United States do paid work in some capacity with many requiring a sheltered work environment. Support in financial and legal matters is often needed. Life expectancy is around 50 to 60 years in the developed world with proper health care.
Down syndrome is one of the most common chromosome abnormalities in humans. It occurs in about one per 1000 babies born each year. In 2013, Down syndrome was present in 8.5 million individuals and resulted in 36,000 deaths down from 43,000 deaths in 1990. It is named after John Langdon Down, the British doctor who fully described the syndrome in 1866. Some aspects of the condition were described earlier by Jean-Étienne Dominique Esquirol in 1838 and Édouard Séguin in 1844. In 1957, the genetic cause of Down syndrome, an extra copy of chromosome 21, was discovered., Palliative care is a multidisciplinary approach to specialized medical care for people with life-limiting illnesses. It focuses on providing people with relief from the symptoms, pain, physical stress, and mental stress of the terminal diagnosis. The goal of such therapy is to improve quality of life for both the person and their family. Evidence as of 2016 supports improvement in quality of life., Denmark is a Scandinavian country in Europe. The southernmost and smallest of the Nordic countries, it is south-west of Sweden and south of Norway, and bordered to the south by Germany. The Kingdom of Denmark is the sovereign state that comprises Denmark proper and two autonomous constituent countries in the North Atlantic Ocean: the Faroe Islands and Greenland. Denmark has a total area of , and a population of 5.7 million. The country consists of a peninsula, Jutland, and an archipelago of 443 named islands, with the largest being Zealand and Funen. The islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate., The European Film Academy (EFA) is an initiative of a group of European filmmakers who came together in Berlin on the occasion of the first presentation of the European Film Awards in November 1988., Lithuanians (singular "lietuvis/lietuv") are a Baltic ethnic group, native to Lithuania, where they number around 2,561,300 people. Another million or more make up the Lithuanian diaspora, largely found in countries such as the United States, Argentina, Brazil, Canada, Colombia, Russia, United Kingdom and Ireland. Their native language is Lithuanian, one of only two surviving members of the Baltic language family. According to the census conducted in 2001, 83.45% of the population of Lithuania identified themselves as Lithuanians, 6.74% as Poles, 6.31% as Russians, 1.23% as Belarusians, and 2.27% as members of other ethnic groups. Most Lithuanians belong to the Roman Catholic Church, while the Lietuvininkai who lived in the northern part of East Prussia prior to World War II, were mostly Evangelical Lutherans., A documentary film is a nonfictional motion picture intended to some aspect of reality, primarily for the purposes of instruction, education, or maintaining a historical record. Such films were originally shot on film stockthe only medium availablebut now include video and digital productions that can be either direct-to-video, made into a TV show, or released for screening in cinemas. "Documentary" has been described as a "filmmaking practice, a cinematic tradition, and mode of audience reception" that is continually evolving and is without clear boundaries., A global city, also called world city or sometimes alpha city or world center, is a city generally considered to be an important node in the global economic system. The concept comes from geography and urban studies, and the idea that globalization can be understood as largely created, facilitated, and enacted in strategic geographic locales according to a hierarchy of importance to the operation of the global system of finance and trade., Film stock is an analog medium that is used for recording motion pictures or animation. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to X-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into the infrared (IR) region of the spectrum., Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology., Smoking is a practice in which a substance is burned and the resulting smoke breathed in to be tasted and absorbed into the bloodstream. Most commonly the substance is the dried leaves of the tobacco plant which have been rolled into a small square of rice paper to create a small, round cylinder called a "cigarette". Smoking is primarily practiced as a route of administration for recreational drug use because the combustion of the dried plant leaves vaporizes and delivers active substances into the lungs where they are rapidly absorbed into the bloodstream and reach bodily tissue. In the case of cigarette smoking these substances are contained in a mixture of aerosol particles and gasses and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas to form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs. In some cultures, smoking is also carried out as a part of various rituals, where participants use it to help induce trance-like states that, they believe, can lead them to "spiritual enlightenment"., Lithuania (UK and US: ), officially the Republic of Lithuania, is a country in Northern Europe. One of the three Baltic states, it is situated along the southeastern shore of the Baltic Sea, to the east of Sweden and Denmark. It is bordered by Latvia to the north, Belarus to the east and south, Poland to the south, and Kaliningrad Oblast (a Russian exclave) to the southwest. Lithuania has an estimated population of 2.9 million people , and its capital and largest city is Vilnius. Lithuanians are a Baltic people. The official language, Lithuanian, along with Latvian, is one of only two living languages in the Baltic branch of the Indo-European language family., Napoleon Bonaparte ("Napoléon Bonaparte";  , born ""Napoleone di Buonaparte""; 15 August 1769  5 May 1821) was a French military and political leader who rose to prominence during the French Revolution and led several successful campaigns during the French Revolutionary Wars. As Napoleon I, he was Emperor of the French from 1804 until 1814, and again in 1815. Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions in the Napoleonic Wars. He won most of these wars and the vast majority of his battles, building a large empire that ruled over continental Europe before its final collapse in 1815. One of the greatest commanders in history, his wars and campaigns are studied at military schools worldwide. Napoleon's political and cultural legacy has ensured his status as one of the most celebrated and controversial leaders in human history., The Indo-European languages are a language family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by "Ethnologue", with over two-thirds (313) of them belonging to the Indo-Iranian branch. The most widely spoken Indo-European languages by native speakers are Spanish, English, Hindustani (Hindi and Urdu), Portuguese, Bengali, Russian, Persian and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an Indo-European language natively, by far the highest of any language family., Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets., A haiku in English is a very short poem in the English language, following to a greater or lesser extent the form and style of the Japanese haiku. A typical haiku is a three-line observation about a fleeting moment involving nature., Subject: before flying back to earth, Relation: main_subject, Options: (A) africa (B) aids (C) arctic (D) border (E) canada (F) cancer (G) child (H) childhood (I) city (J) denmark (K) design (L) education (M) english (N) europe (O) family (P) film (Q) filmmaking (R) french revolution (S) french revolutionary wars (T) function (U) globalization (V) health care (W) history (X) human rights (Y) language (Z) language family ([) law (\) life (]) mathematics (^) mountain (_) music (`) napoleonic wars (a) nature (b) organization (c) plant (d) reality (e) recreational drug use (f) russia (g) television (h) time (i) trade (j) true (k) united kingdom (l) united nations (m) vhs (n) war
