Question: Family history is a risk factor for asthma, with many different genes being implicated. If one identical twin is affected, the probability of the other having the disease is approximately 25%. By the end of 2005, 25 genes had been associated with asthma in six or more separate populations, including GSTM1, IL10, CTLA-4, SPINK5, LTC4S, IL4R and ADAM33, among others. Many of these genes are related to the immune system or modulating inflammation. Even among this list of genes supported by highly replicated studies, results have not been consistent among all populations tested. In 2006 over 100 genes were associated with asthma in one genetic association study alone; more continue to be found.
Is there an answer to this question: What else are these genes closely related to?

Answer: the immune system or modulating inflammation

Question: Paris is a city of books and bookstores. In the 1970s, 80 percent of French-language publishing houses were found in Paris, almost all on the Left Bank in the 5th, 6th and 7th arrondissements. Since that time, because of high prices, some publishers have moved out to the less expensive areas. It is also a city of small bookstores; There are about 150 bookstores in the 5th arrondissement alone, plus another 250 book stalls along the Seine. Small Paris bookstores are protected against competition from discount booksellers by French law; books, even e-books, cannot be discounted more than five percent below their publisher's cover price.
Is there an answer to this question: How many bookstalls are located along the Seine?

Answer: 250

Question: All government officers of the United States, including the President, the Justices of the Supreme Court, state judges and legislators, and all members of Congress, pledge first and foremost to uphold the Constitution. These oaths affirm that the rule of law is superior to the rule of any human leader. At the same time, the federal government has considerable discretion: the legislative branch is free to decide what statutes it will write, as long as it stays within its enumerated powers and respects the constitutionally protected rights of individuals. Likewise, the judicial branch has a degree of judicial discretion, and the executive branch also has various discretionary powers including prosecutorial discretion.
Is there an answer to this question: What branch of government can determine what acts it writes?

Answer: legislative branch

Question: The Antarctic fur seal was very heavily hunted in the 18th and 19th centuries for its pelt by sealers from the United States and the United Kingdom. The Weddell seal, a "true seal", is named after Sir James Weddell, commander of British sealing expeditions in the Weddell Sea. Antarctic krill, which congregate in large schools, is the keystone species of the ecosystem of the Southern Ocean, and is an important food organism for whales, seals, leopard seals, fur seals, squid, icefish, penguins, albatrosses and many other birds.
Is there an answer to this question: What is the keystone species of the Arctic Ocean?

Answer:
