Question: Since the late twentieth century, the number of African and Caribbean ethnic African immigrants have increased in the United States. Together with publicity about the ancestry of President Barack Obama, whose father was from Kenya, some black writers have argued that new terms are needed for recent immigrants. They suggest that the term "African-American" should refer strictly to the descendants of African slaves and free people of color who survived the slavery era in the United States. They argue that grouping together all ethnic Africans regardless of their unique ancestral circumstances would deny the lingering effects of slavery within the American slave descendant community. They say recent ethnic African immigrants need to recognize their own unique ancestral backgrounds.
Try to answer this question if possible: Who do black writers say should not recognize their own unique ancestral backgrounds?
Answer: unanswerable
Question: Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 has the distinction of being the only naturally occurring fissile isotope. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. While uranium-238 has a small probability for spontaneous fission or even induced fission with fast neutrons, uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction. This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating.

Answer: Uranium-238
Question: Jonassohn and Bjornson postulate that the major reason why no single generally accepted genocide definition has emerged is because academics have adjusted their focus to emphasise different periods and have found it expedient to use slightly different definitions to help them interpret events. For example, Frank Chalk and Kurt Jonassohn studied the whole of human history, while Leo Kuper and R. J. Rummel in their more recent works concentrated on the 20th century, and Helen Fein, Barbara Harff and Ted Gurr have looked at post World War II events. Jonassohn and Bjornson are critical of some of these studies, arguing that they are too expansive, and conclude that the academic discipline of genocide studies is too young to have a canon of work on which to build an academic paradigm.
Try to answer this question if possible: What two writers examined the lack of an accepted and singular definition for genocide?
Answer: Jonassohn and Bjornson
