Passage: A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.

Question: What is the use of solar balloons typically limited to?

Question: Why is the use of solar balloons typically limited to the toy market?
Passage: Beginning with the surge in coal use which accompanied the Industrial Revolution, energy consumption has steadily transitioned from wood and biomass to fossil fuels. The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce. However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum.

Question: Why was solar technology developed in the 1860s?

Question: What slowed the development of solar technologies in the early 20th century?
Passage: In 2011, a report by the International Energy Agency found that solar energy technologies such as photovoltaics, solar hot water and concentrated solar power could provide a third of the world’s energy by 2060 if politicians commit to limiting climate change. The energy from the sun could play a key role in de-carbonizing the global economy alongside improvements in energy efficiency and imposing costs on greenhouse gas emitters. "The strength of solar is the incredible variety and flexibility of applications, from small scale to big scale".

Question: According to a report in 2011, by what year could solar energy provide a third of the world's energy?

Question: What could the sun's energy do to help limit climate change?
Passage: The territory that now constitutes Tajikistan was previously home to several ancient cultures, including the city of Sarazm of the Neolithic and the Bronze Age, and was later home to kingdoms ruled by people of different faiths and cultures, including the Oxus civilization, Andronovo culture, Buddhism, Nestorian Christianity, Zoroastrianism, and Manichaeism. The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sassanian Empire, Hephthalite Empire, Samanid Empire, Mongol Empire, Timurid dynasty, and the Russian Empire. As a result of the breakup of the Soviet Union, Tajikistan became an independent nation in 1991. A civil war was fought almost immediately after independence, lasting from 1992 to 1997.

Passage: Tajiks began to be conscripted into the Soviet Army in 1939 and during World War II around 260,000 Tajik citizens fought against Germany, Finland and Japan. Between 60,000(4%) and 120,000(8%) of Tajikistan's 1,530,000 citizens were killed during World War II. Following the war and Stalin's reign attempts were made to further expand the agriculture and industry of Tajikistan. During 1957–58 Nikita Khrushchev's Virgin Lands Campaign focused attention on Tajikistan, where living conditions, education and industry lagged behind the other Soviet Republics. In the 1980s, Tajikistan had the lowest household saving rate in the USSR, the lowest percentage of households in the two top per capita income groups, and the lowest rate of university graduates per 1000 people. By the late 1980s Tajik nationalists were calling for increased rights. Real disturbances did not occur within the republic until 1990. The following year, the Soviet Union collapsed, and Tajikistan declared its independence.

Passage: The nation almost immediately fell into civil war that involved various factions fighting one another; these factions were often distinguished by clan loyalties. More than 500,000 residents fled during this time because of persecution, increased poverty and better economic opportunities in the West or in other former Soviet republics. Emomali Rahmon came to power in 1992, defeating former prime minister Abdumalik Abdullajanov in a November presidential election with 58% of the vote. The elections took place shortly after the end of the war, and Tajikistan was in a state of complete devastation. The estimated dead numbered over 100,000. Around 1.2 million people were refugees inside and outside of the country. In 1997, a ceasefire was reached between Rahmon and opposition parties under the guidance of Gerd D. Merrem, Special Representative to the Secretary General, a result widely praised as a successful United Nations peace keeping initiative. The ceasefire guaranteed 30% of ministerial positions would go to the opposition. Elections were held in 1999, though they were criticized by opposition parties and foreign observers as unfair and Rahmon was re-elected with 98% of the vote. Elections in 2006 were again won by Rahmon (with 79% of the vote) and he began his third term in office. Several opposition parties boycotted the 2006 election and the Organization for Security and Cooperation in Europe (OSCE) criticized it, although observers from the Commonwealth of Independent States claimed the elections were legal and transparent. Rahmon's administration came under further criticism from the OSCE in October 2010 for its censorship and repression of the media. The OSCE claimed that the Tajik Government censored Tajik and foreign websites and instituted tax inspections on independent printing houses that led to the cessation of printing activities for a number of independent newspapers.

Passage: Freedom of the press is ostensibly officially guaranteed by the government, but independent press outlets remain restricted, as does a substantial amount of web content. According to the Institute for War & Peace Reporting, access is blocked to local and foreign websites including avesta.tj, Tjknews.com, ferghana.ru, centrasia.ru and journalists are often obstructed from reporting on controversial events.

Passage: Tajikistan is landlocked, and is the smallest nation in Central Asia by area. It lies mostly between latitudes 36° and 41° N (a small area is north of 41°), and longitudes 67° and 75° E (a small area is east of 75°). It is covered by mountains of the Pamir range, and more than fifty percent of the country is over 3,000 meters (9,800 ft) above sea level. The only major areas of lower land are in the north (part of the Fergana Valley), and in the southern Kofarnihon and Vakhsh river valleys, which form the Amu Darya.

Passage: Tajikistan means the "Land of the Tajiks". The suffix "-stan" (Persian: ـستان‎‎ -stān) is Persian for "place of" or "country" and Tajik is, most likely, the name of a pre-Islamic (before the seventh century A.D.) tribe. According to the Library of Congress's 1997 Country Study of Tajikistan, it is difficult to definitively state the origins of the word "Tajik" because the term is "embroiled in twentieth-century political disputes about whether Turkic or Iranian peoples were the original inhabitants of Central Asia."

Passage: It was temporarily under the control of the Tibetan empire and Chinese from 650–680 and then under the control of the Umayyads in 710. The Samanid Empire, 819 to 999, restored Persian control of the region and enlarged the cities of Samarkand and Bukhara (both cities are today part of Uzbekistan) which became the cultural centers of Iran and the region was known as Khorasan. The Kara-Khanid Khanate conquered Transoxania (which corresponds approximately with modern-day Uzbekistan, Tajikistan, southern Kyrgyzstan and southwest Kazakhstan) and ruled between 999–1211. Their arrival in Transoxania signaled a definitive shift from Iranian to Turkic predominance in Central Asia, but gradually the Kara-khanids became assimilated into the Perso-Arab Muslim culture of the region.

Passage: Russian Imperialism led to the Russian Empire's conquest of Central Asia during the late 19th century's Imperial Era. Between 1864 and 1885 Russia gradually took control of the entire territory of Russian Turkestan, the Tajikistan portion of which had been controlled by the Emirate of Bukhara and Khanate of Kokand. Russia was interested in gaining access to a supply of cotton and in the 1870s attempted to switch cultivation in the region from grain to cotton (a strategy later copied and expanded by the Soviets).[citation needed] By 1885 Tajikistan's territory was either ruled by the Russian Empire or its vassal state, the Emirate of Bukhara, nevertheless Tajiks felt little Russian influence.[citation needed]

Passage: During the late 19th Century the Jadidists established themselves as an Islamic social movement throughout the region. Although the Jadidists were pro-modernization and not necessarily anti-Russian the Russians viewed the movement as a threat.[citation needed] Russian troops were required to restore order during uprisings against the Khanate of Kokand between 1910 and 1913. Further violence occurred in July 1916 when demonstrators attacked Russian soldiers in Khujand over the threat of forced conscription during World War I.

Passage: After the Russian Revolution of 1917 guerrillas throughout Central Asia, known as basmachi, waged a war against Bolshevik armies in a futile attempt to maintain independence. The Bolsheviks prevailed after a four-year war, in which mosques and villages were burned down and the population heavily suppressed. Soviet authorities started a campaign of secularization, practicing Islam, Judaism, and Christianity was discouraged and repressed, and many mosques, churches, and synagogues were closed.

Passage: In 1924, the Tajik Autonomous Soviet Socialist Republic was created as a part of Uzbekistan, but in 1929 the Tajik Soviet Socialist Republic (Tajik SSR) was made a separate constituent republic, however the predominantly ethnic Tajik cities of Samarkand and Bukhara remained in the Uzbek SSR. Between 1927 and 1934, collectivization of agriculture and a rapid expansion of cotton production took place, especially in the southern region. Soviet collectivization policy brought violence against peasants and forced resettlement occurred throughout Tajikistan. Consequently, some peasants fought collectivization and revived the Basmachi movement.

Passage: Two rounds of Soviet purges directed by Moscow (1927–1934 and 1937–1938) resulted in the expulsion of nearly 10,000 people, from all levels of the Communist Party of Tajikistan. Ethnic Russians were sent in to replace those expelled and subsequently Russians dominated party positions at all levels, including the top position of first secretary. Between 1926 and 1959 the proportion of Russians among Tajikistan's population grew from less than 1% to 13%. Bobojon Ghafurov, Tajikistan's First Secretary of the Communist Party of Tajikistan from 1946–1956 was the only Tajikistani politician of significance outside of the country during the Soviet Era. He was followed in office by Tursun Uljabayev (1956–61), Jabbor Rasulov (1961–1982), and Rahmon Nabiyev (1982–1985, 1991–1992).

Passage: The parliamentary elections of 2005 aroused many accusations from opposition parties and international observers that President Emomalii Rahmon corruptly manipulates the election process and unemployment. The most recent elections, in February 2010, saw the ruling PDPT lose four seats in Parliament, yet still maintain a comfortable majority. The Organization for Security and Co-operation in Europe election observers said the 2010 polling "failed to meet many key OSCE commitments" and that "these elections failed on many basic democratic standards." The government insisted that only minor violations had occurred, which would not affect the will of the Tajik people.

Passage: The earliest recorded history of the region dates back to about 500 BCE when much, if not all, of modern Tajikistan was part of the Achaemenid Empire. Some authors have also suggested that in the 7th and 6th century BCE parts of modern Tajikistan, including territories in the Zeravshan valley, formed part of Kambojas before it became part of the Achaemenid Empire. After the region's conquest by Alexander the Great it became part of the Greco-Bactrian Kingdom, a successor state of Alexander's empire. Northern Tajikistan (the cities of Khujand and Panjakent) was part of Sogdia, a collection of city-states which was overrun by Scythians and Yuezhi nomadic tribes around 150 BCE. The Silk Road passed through the region and following the expedition of Chinese explorer Zhang Qian during the reign of Wudi (141–87 BCE) commercial relations between Han China and Sogdiana flourished. Sogdians played a major role in facilitating trade and also worked in other capacities, as farmers, carpetweavers, glassmakers, and woodcarvers.
