Question: Israel's diverse culture stems from the diversity of its population: Jews from diaspora communities around the world have brought their cultural and religious traditions back with them, creating a melting pot of Jewish customs and beliefs. Israel is the only country in the world where life revolves around the Hebrew calendar. Work and school holidays are determined by the Jewish holidays, and the official day of rest is Saturday, the Jewish Sabbath. Israel's substantial Arab minority has also left its imprint on Israeli culture in such spheres as architecture, music, and cuisine.
Is there an answer to this question: Where does Israel's diverse culture stem from?

Answer: diversity of its population


Question: When endothermy first appeared in the evolution of mammals is uncertain. Modern monotremes have lower body temperatures and more variable metabolic rates than marsupials and placentals, but there is evidence that some of their ancestors, perhaps including ancestors of the therians, may have had body temperatures like those of modern therians. Some of the evidence found so far suggests that Triassic cynodonts had fairly high metabolic rates, but it is not conclusive. For small animals, an insulative covering like fur is necessary for the maintenance of a high and stable body temperature.
Is there an answer to this question: What do placentals use their fur covering for?

Answer: unanswerable


Question: Studies of autosomal DNA, which look at the entire DNA mixture, have become increasingly important as the technology develops. They show that Jewish populations have tended to form relatively closely related groups in independent communities, with most in a community sharing significant ancestry in common. For Jewish populations of the diaspora, the genetic composition of Ashkenazi, Sephardi, and Mizrahi Jewish populations show a predominant amount of shared Middle Eastern ancestry. According to Behar, the most parsimonious explanation for this shared Middle Eastern ancestry is that it is "consistent with the historical formulation of the Jewish people as descending from ancient Hebrew and Israelite residents of the Levant" and "the dispersion of the people of ancient Israel throughout the Old World". North African, Italian and others of Iberian origin show variable frequencies of admixture with non-Jewish historical host populations among the maternal lines. In the case of Ashkenazi and Sephardi Jews (in particular Moroccan Jews), who are closely related, the source of non-Jewish admixture is mainly southern European, while Mizrahi Jews show evidence of admixture with other Middle Eastern populations and Sub-Saharan Africans. Behar et al. have remarked on an especially close relationship of Ashkenazi Jews and modern Italians.
Is there an answer to this question: What does not show shared Middle Eastern ancestry?

Answer: unanswerable


Question: Among Ike's objectives in not directly confronting McCarthy was to prevent McCarthy from dragging the Atomic Energy Commission (AEC) into McCarthy's witch hunt for communists, which would interfere with, and perhaps delay, the AEC's important work on H-bombs. The administration had discovered through its own investigations that one of the leading scientists on the AEC, J. Robert Oppenheimer, had urged that the H-bomb work be delayed. Eisenhower removed him from the agency and revoked his security clearance, though he knew this would create fertile ground for McCarthy.
Is there an answer to this question: What AEC scientists counseled delaying the development of the hydrogen bomb?

Answer:
J. Robert Oppenheimer
