Context: Estrogens and progesterone typically regulate motivation to engage in sexual reproduction behaviour for females in mammalian species, though the relationship between hormones and female sexual motivation is not as well understood. In particular, estrogens have been shown to correlate positively with increases in female sexual motivation, and progesterone has been associated with decreases in female sexual motivation. The periovulatory period of the female menstrual cycle is often associated with increased female receptivity and sexual motivation. During this stage in the cycle, estrogens are elevated in the female and progesterone levels are low. At this time, mating can result in female pregnancy.
Answerable: yes
Answer: Estrogens and progesterone
Question: হৃদ রোগ প্রথম কে শনাক্ত করেন ?
Context: Treatment depends on the severity and cause of the disease. In people with chronic stable mild heart failure, treatment commonly consists of lifestyle modifications such as stopping smoking, physical exercise, and dietary changes, as well as medications. In those with heart failure due to left ventricular dysfunction, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or valsartan/sacubitril along with beta blockers are recommended. For those with severe disease, aldosterone antagonists, or hydralazine with a nitrate may be used. Diuretics are useful for preventing fluid retention and the resulting shortness of breath. Sometimes, depending on the cause, an implanted device such as a pacemaker or an implantable cardiac defibrillator (ICD) may be recommended. In some moderate or severe cases, cardiac resynchronization therapy (CRT) or cardiac contractility modulation may be of benefit. A ventricular assist device or occasionally a heart transplant may be recommended in those with severe disease that persists despite all other measures.
Heart failure is a common, costly, and potentially fatal condition. In 2015, it affected about 40 million people globally. Overall around 2% of adults have heart failure and in those over the age of 65, this increases to 6–10%. Rates are predicted to increase. The risk of death is about 35% the first year after diagnosis; while by the second year the risk of death is less than 10% for those who remain alive. This degree of risk of death is similar to some cancers. In the United Kingdom, the disease is the reason for 5% of emergency hospital admissions. Heart failure has been known since ancient times with the Ebers papyrus commenting on it around 1550 BCE.
Answerable: yes
Answer: Ebers papyrus

Question: বিবর্তনীয় মনোবিজ্ঞান মূলত কয়টি শাখায় বিভক্ত ?
Context: From psychology there are the primary streams of developmental, social and cognitive psychology. Establishing some measure of the relative influence of genetics and environment on behavior has been at the core of behavioral genetics and its variants, notably studies at the molecular level that examine the relationship between genes, neurotransmitters and behavior. Dual inheritance theory (DIT), developed in the late 1970s and early 1980s, has a slightly different perspective by trying to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. DIT is seen by some as a "middle-ground" between views that emphasize human universals versus those that emphasize cultural variation.

Question: যিশু খ্রিস্ট কোথায় জন্মগ্রহণ করেন ?
Context: The nativity of Jesus or birth of Jesus is the basis for the Christian holiday of Christmas and is described in the gospels of Luke and Matthew. The two accounts differ, but agree that Jesus was born in Bethlehem in Judea during the reign of King Herod the Great, his mother Mary was married to a man named Joseph, who was descended from King David and was not his biological father, and that his birth was caused by divine intervention. Luke's version says the birth took place during a Roman census, mentions an announcement to shepherds by angels, presentation of Jesus in the Temple, and gives the name of the angel who announces the coming birth to Mary (the archangel Gabriel). Matthew's version mentions the arrival of the Magi, the flight into Egypt by the family, and the Massacre of the Innocents by King Herod. The consensus of scholars is that both gospels were written about AD 75-85, and while it is possible that one account might be based on the other, or that the two share common source material, the majority conclusion is that the two nativity narratives are independent of each other.
Answerable: yes
Answer: Bethlehem

Context: The Two Gentlemen of Verona is a comedy by William Shakespeare, believed to have been written between 1589 and 1593.

Question: মস্তিষ্কের কোন অংশ দ্বারা মানুষের চেতনা পরিচালিত হয় ?
Context: In neuroscience, a great deal of effort has gone into investigating how the perceived world of conscious awareness is constructed inside the brain. The process is generally thought to involve two primary mechanisms: (1) hierarchical processing of sensory inputs, and (2) memory. Signals arising from sensory organs are transmitted to the brain and then processed in a series of stages, which extract multiple types of information from the raw input. In the visual system, for example, sensory signals from the eyes are transmitted to the thalamus and then to the primary visual cortex; inside the cerebral cortex they are sent to areas that extract features such as three-dimensional structure, shape, color, and motion. Memory comes into play in at least two ways. First, it allows sensory information to be evaluated in the context of previous experience. Second, and even more importantly, working memory allows information to be integrated over time so that it can generate a stable representation of the world—Gerald Edelman expressed this point vividly by titling one of his books about consciousness "The Remembered Present". In computational neuroscience, Bayesian approaches to brain function have been used to understand both the evaluation of sensory information in light of previous experience, and the integration of information over time. Bayesian models of the brain are probabilistic inference models, in which the brain takes advantage of prior knowledge to interpret uncertain sensory inputs in order to formulate a conscious percept; Bayesian models have successfully predicted many perceptual phenomena in vision and the nonvisual senses.
Answerable: yes
Answer: cerebral cortex

Question: ভারতবর্ষের কোন অঞ্চলে সারাবছর সবচেয়ে বেশি বৃষ্টিপাত হয় ?
Context: The monsoon accounts for 80% of the rainfall in India. Indian agriculture (which accounts for 25% of the GDP and employs 70% of the population) is heavily dependent on the rains, for growing crops especially like cotton, rice, oilseeds and coarse grains. A delay of a few days in the arrival of the monsoon can badly affect the economy, as evidenced in the numerous droughts in India in the 1990s. The monsoon is widely welcomed and appreciated by city-dwellers as well, for it provides relief from the climax of summer heat in June. However, the condition of the roads take a battering each year. Often houses and streets are waterlogged and the slums are flooded in spite of having a drainage system. This lack of city infrastructure coupled with changing climate patterns causes severe economical loss including damage to property and loss of lives, as evidenced in the Bombay floods of 2005. Bangladesh and certain regions of India like Assam and West Bengal, also frequently experience heavy floods during this season. And in the recent past, areas in India that used to receive scanty rainfall throughout the year, like the Thar Desert, have surprisingly ended up receiving floods due to the prolonged monsoon season.
Answerable: yes
Answer: monsoon

Question: স্ট্যানলি কুবরিক কত সালে প্রথম একাডেমি পুরস্কার পেয়েছিলেন ?
Context: Upon release in 1968, "2001: A Space Odyssey" was not an immediate hit among critics, who faulted its lack of dialog, slow pacing, and seemingly impenetrable storyline. The film appeared to defy genre convention, much unlike any science-fiction movie before it, and clearly different from any of Kubrick's earlier films or stories. Kubrick was particularly outraged by a scathing review from Pauline Kael, who called it "the biggest amateur movie of them all", with Kubrick doing "really every dumb thing he ever wanted to do". Despite mixed reviews from critics at that time, "2001: A Space Odyssey" gradually gained popularity and earned $31 million worldwide by the end of 1972. Today, it is widely considered to be one of the greatest and most influential films ever made, and is a staple on All Time Top 10 lists. Baxter describes the film as "one of the most admired and discussed creations in the history of cinema", and Steven Spielberg has referred to it as "the big bang of his film making generation". For biographer Vincent LoBrutto it "positioned Stanley Kubrick as a pure artist ranked among the masters of cinema".

Question: মিশরের মুহাম্মদ আলি রাজবংশ কবে প্রতিষ্ঠিত হয় ?
Context: Monarchs of the Muhammad Ali dynasty reigned over Egypt from 1805 to 1953. Their rule also extended to Sudan throughout much of this period, as well as to the Levant, and Hejaz during the first half of the 19th century. The Muhammad Ali dynasty was founded by Muhammad Ali Pasha, an Albanian commander in the expeditionary force sent by the Ottoman Empire in 1801 to dislodge the French occupation of Egypt led by Napoleon Bonaparte. The defeat and departure of the French left a power vacuum in Egypt, which had been an Ottoman province since the 16th century, but in which the pre-Ottoman Mamluk military caste maintained considerable power. After a three-year civil war, Muhammad Ali managed to consolidate his control over Egypt, and declared himself Khedive of the country. The Ottoman Porte refused to acknowledge this title, instead recognizing Muhammad Ali by the more junior title of "Wāli" (meaning governor or viceroy) on 18 June 1805, making Muhammad Ali the successor to Ahmad Khurshid Pasha in that position. In the years following his consolidation of power, Muhammad Ali extended Egypt's borders south into Sudan, and eastwards into the Arab Mashreq, particularly the Levant. In 1840, his demand for hereditary control of Egypt and Sudan to be passed to his heirs and successors was accepted and confirmed by the Convention of London, but he was compelled to agree that, upon his death, control over his territories in the Mashreq would revert to the Porte.

Question: জৈনদের পবিত্র ধর্মগ্রন্থের নাম কী ?
Context: Jain scriptures are called "Agamas". They are believed to have been verbally transmitted by the oral tradition from one generation to the next, much like the ancient Buddhist and Hindu texts. The Jain tradition believes that their religion is eternal, and the teachings of their first "Tirthankara Rishabhanatha" were their scriptures millions of years ago. The mythology states that the "tirthankara" taught in a divine preaching hall called "samavasarana", which were heard by the gods, the ascetics and laypersons. The discourse delivered is called "Śhrut Jnāna" and comprises eleven "angas" and fourteen "purvas". The discourse is remembered and transmitted by the "Ganadharas" (chief disciples), and is composed of twelve "angas" (departments). It is symbolically represented by a tree with twelve branches.

Question: আইজাক আসিমভের রচিত প্রথম উপন্যাসের নাম কী ?
Context: The series is set in the same universe as Asimov's first published novel, "Pebble in the Sky", although "Foundation" takes place about 10,000 years later. "Pebble in the Sky" became the basis for the "Empire" series. Then, at some unknown date (prior to writing "Foundation's Edge") Asimov decided to merge the "Foundation"/"Empire" series with his "Robot" series. Thus, all three series are set in the same universe, giving them a combined length of 15 novels, and a total of about 1,500,000 words (see the List of books below). The merge also created a time-span of the series of around 20,000 years.
Answerable: yes
Answer: Pebble in the Sky

Question: আইজাক আসিমভের রচিত প্রথম উপন্যাসের নাম কী ?
Context: Early on during Asimov's original world-building of the "Foundation" universe, he established within the first published stories a chronology placing the tales about 50,000 years into the future from the time they were written ("circa" 1940). This precept was maintained in the pages of his first novel "Pebble in the Sky", wherein Imperial archaeologist Bel Arvardan refers to ancient human strata discovered in the Sirius sector dating back "some 50,000 years". However, when Asimov decided decades later to retroactively integrate the universe of his "Foundation" and "Galactic Empire" novels with that of his "Robot" stories, a number of changes and minor discrepancies surfaced – the character R. Daneel Olivaw was established as having existed for some 20,000 years, with the original "Robot" novels featuring the character occurring not more than a couple of millennia after the early-21st century Susan Calvin short stories. Also, in "Foundation's Edge", mankind was referred to as having possessed interstellar space travel for only 22,000 years, a far cry from the 50 millennia of earlier works.
Answerable: yes
Answer: Pebble in the Sky
Question: বিশ্বের প্রথম ভিডিও গেইম তৈরিকারী সংস্থার নাম কী ?
Context: The first games known to incorporate a monitor were two research projects completed in 1952, a checkers program by Christopher Strachey on the Ferranti Mark 1 and a tic-tac-toe program called "OXO" by Alexander Douglas on the EDSAC. Both of these programs used a relatively static display to track the current state of the game board. The first known game incorporating graphics that updated in real time was a billiards game programmed by William Brown and Ted Lewis specifically for a demonstration of the MIDSAC computer at the University of Michigan in 1954.
Perhaps the first game created solely for entertainment rather than to demonstrate the power of some technology, train personnel, or aid in research was "Tennis for Two", designed by William Higinbotham and built by Robert Dvorak at the Brookhaven National Laboratory in 1958. Designed to entertain the general public at Brookhaven's annual series of open houses, the game was deployed on an analog computer with graphics displayed on an oscilloscope and was dismantled in 1959. Higinbotham never considered adapting the successful game into a commercial product, which would have been impractical with the technology of the time. Ultimately, the widespread adoption of computers to play games would have to wait for the machines to spread from serious academics to their students on U.S. college campuses.
Answerable: yes
Answer: William Higinbotham
Question: চীন কি একটি সার্বভৌম দেশ ?
Context: The position of PRC is that the ROC and PRC are two different factions in the Chinese Civil War, which never legally ended. Therefore the PRC claims that both factions belong to the same sovereign country—China. Since, as per the PRC, Taiwan's sovereignty belongs to China, the PRC's government and supporters believe that the secession of Taiwan should be agreed upon by all 1.3 billion Chinese citizens instead of just the 23 million residents of Taiwan. Furthermore, the position of PRC is that UN General Assembly Resolution 2758, which states "Recognizing that the representatives of the Government of the People's Republic of China are the only lawful representatives of China to the United Nations", means that the PRC is recognized as having the sovereignty of all of China, including Taiwan. Therefore, the PRC believes that it is within their legal rights to extend its jurisdiction to Taiwan, by military means if at all necessary.

Question: সৈন্যবাহিনীর বিচারে ২০১৮ সালে বিশ্বের কোন দেশ সবথেকে বেশি শক্তিশালী ?
Context: An important part of the military intelligence role is the military analysis performed to assess military capability of potential future aggressors, and provide combat modelling that helps to understand factors on which comparison of forces can be made. This helps to quantify and qualify such statements as: "China and India maintain the largest armed forces in the World" or that "the U.S. Military is considered to be the world's strongest".
Although some groups engaged in combat, such as militants or resistance movements, refer to themselves using military terminology, notably 'Army' or 'Front', none have had the structure of a national military to justify the reference, and usually have had to rely on support of outside national militaries. They also use these terms to conceal from the MI their true capabilities, and to impress potential ideological recruits.
Answerable: yes
Answer: U.S. Military is considered to be the world's strongest
