Context and question: Insects play important roles in biological research. For example, because of its small size, short generation time and high fecundity, the common fruit fly Drosophila melanogaster is a model organism for studies in the genetics of higher eukaryotes. D. melanogaster has been an essential part of studies into principles like genetic linkage, interactions between genes, chromosomal genetics, development, behavior and evolution. Because genetic systems are well conserved among eukaryotes, understanding basic cellular processes like DNA replication or transcription in fruit flies can help to understand those processes in other eukaryotes, including humans. The genome of D. melanogaster was sequenced in 2000, reflecting the organism's important role in biological research. It was found that 70% of the fly genome is similar to the human genome, supporting the evolution theory.
What is a common insect used for research purposes?
Answer: fruit fly Drosophila melanogaster
Context and question: Following the Xinhai Revolution against the Qing dynasty in 1912, Qing soldiers were disarmed and escorted out of Tibet Area (U-Tsang). The region subsequently declared its independence in 1913 without recognition by the subsequent Chinese Republican government. Later, Lhasa took control of the western part of Xikang, China. The region maintained its autonomy until 1951 when, following the Battle of Chamdo, Tibet became incorporated into the People's Republic of China, and the previous Tibetan government was abolished in 1959 after a failed uprising. Today, China governs western and central Tibet as the Tibet Autonomous Region while the eastern areas are now mostly ethnic autonomous prefectures within Sichuan, Qinghai and other neighbouring provinces. There are tensions regarding Tibet's political status and dissident groups that are active in exile. It is also said that Tibetan activists in Tibet have been arrested or tortured.
Where did Tibet become incorporated into in 1915?
Answer: unanswerable
Context and question: President Franklin D. Roosevelt promoted a "good neighbor" policy that sought better relations with Mexico. In 1935 a federal judge ruled that three Mexican immigrants were ineligible for citizenship because they were not white, as required by federal law. Mexico protested, and Roosevelt decided to circumvent the decision and make sure the federal government treated Hispanics as white. The State Department, the Census Bureau, the Labor Department, and other government agencies therefore made sure to uniformly classify people of Mexican descent as white. This policy encouraged the League of United Latin American Citizens in its quest to minimize discrimination by asserting their whiteness.
People of what descent were classified as white by the federal government at the suggestion of President Roosevelt?
Answer:
Mexican
