Problem: Rajasthan (/ˈrɑːdʒəstæn/ Hindustani pronunciation: [raːdʒəsˈt̪ʰaːn] ( listen); literally, "Land of Kings") is India's largest state by area (342,239 square kilometres (132,139 sq mi) or 10.4% of India's total area). It is located on the western side of the country, where it comprises most of the wide and inhospitable Thar Desert (also known as the "Rajasthan Desert" and "Great Indian Desert") and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej-Indus river valley. Elsewhere it is bordered by the other Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest. Its features include the ruins of the Indus Valley Civilization at Kalibanga; the Dilwara Temples, a Jain pilgrimage site at Rajasthan's only hill station, Mount Abu, in the ancient Aravalli mountain range; and, in eastern Rajasthan, the Keoladeo National Park near Bharatpur, a World Heritage Site known for its bird life. Rajasthan is also home to two national tiger reserves, the Ranthambore National Park in Sawai Madhopur and Sariska Tiger Reserve in Alwar.
What percentage of India's total area is Rajasthan?
The answer is the following: 10.4%

Problem: Black labor played a crucial role in Miami's early development. During the beginning of the 20th century, migrants from the Bahamas and African-Americans constituted 40 percent of the city's population. Whatever their role in the city's growth, their community's growth was limited to a small space. When landlords began to rent homes to African-Americans in neighborhoods close to Avenue J (what would later become NW Fifth Avenue), a gang of white man with torches visited the renting families and warned them to move or be bombed.
Where did a portion of Miami's black population migrate from in the early 1900s?
The answer is the following: Bahamas

Problem: Electroluminescence as a phenomenon was discovered in 1907 by the British experimenter H. J. Round of Marconi Labs, using a crystal of silicon carbide and a cat's-whisker detector. Soviet inventor Oleg Losev reported creation of the first LED in 1927. His research was distributed in Soviet, German and British scientific journals, but no practical use was made of the discovery for several decades. Kurt Lehovec, Carl Accardo and Edward Jamgochian, explained these first light-emitting diodes in 1951 using an apparatus employing SiC crystals with a current source of battery or pulse generator and with a comparison to a variant, pure, crystal in 1953.
What was the nationality of the man who discovered Electroluminescence?
The answer is the following: British

Problem: During the Cenozoic era, specifically about 25 million years ago during the Miocene and Pliocene epochs, the continental climate became favorable to the evolution of grasslands. Existing forest biomes declined and grasslands became much more widespread. The grasslands provided a new niche for mammals, including many ungulates and glires, that switched from browsing diets to grazing diets. Traditionally, the spread of grasslands and the development of grazers have been strongly linked. However, an examination of mammalian teeth suggests that it is the open, gritty habitat and not the grass itself which is linked to diet changes in mammals, giving rise to the "grit, not grass" hypothesis.
the spread of grasslands and what have been strongly linked?
The answer is the following:
development of grazers
