Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Craig Venter and Francis Collins of the National Institute of Health jointly made the announcement of the mapping of the human genome in 2000. Upon examining the data from the genome mapping, Venter realized that although the genetic variation within the human species is on the order of 13% (instead of the previously assumed 1%), the types of variations do not support notion of genetically defined races. Venter said, "Race is a social concept. It's not a scientific one. There are no bright lines (that would stand out), if we could compare all the sequenced genomes of everyone on the planet." "When we try to apply science to try to sort out these social differences, it all falls apart.""?

A: If race is a social concept, then differences within the human species are of what kind?

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "In the United States, the term "treaty" has a different, more restricted legal sense than exists in international law. United States law distinguishes what it calls treaties from executive agreement, congressional-executive agreements, and sole executive agreements. All four classes are equally treaties under international law; they are distinct only from the perspective of internal American law. The distinctions are primarily concerning their method of approval. Whereas treaties require advice and consent by two-thirds of the Senators present, sole executive agreements may be executed by the President acting alone. Some treaties grant the President the authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. And finally, congressional-executive agreements require majority approval by both the House and the Senate, either before or after the treaty is signed by the President."?

A: In international relations which body of jurisprudence generally defines treaties between nations?

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Kerry said that he had intended the remark as a jab at President Bush, and described the remarks as a "botched joke", having inadvertently left out the key word "us" (which would have been, "If you don't, you get us stuck in Iraq"), as well as leaving the phrase "just ask President Bush" off of the end of the sentence. In Kerry's prepared remarks, which he released during the ensuing media frenzy, the corresponding line was "... you end up getting us stuck in a war in Iraq. Just ask President Bush." He also said that from the context of the speech which, prior to the "stuck in Iraq" line, made several specific references to Bush and elements of his biography, that Kerry was referring to President Bush and not American troops in general."?

A: Where did Kerry reference Bush?

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Short-distance passerine migrants have two evolutionary origins. Those that have long-distance migrants in the same family, such as the common chiffchaff Phylloscopus collybita, are species of southern hemisphere origins that have progressively shortened their return migration to stay in the northern hemisphere."?

A:
The shortening of the return of migration has what?
