Here is a question about this article: This large collection of meteorites allows a better understanding of the abundance of meteorite types in the solar system and how meteorites relate to asteroids and comets. New types of meteorites and rare meteorites have been found. Among these are pieces blasted off the Moon, and probably Mars, by impacts. These specimens, particularly ALH84001 discovered by ANSMET, are at the center of the controversy about possible evidence of microbial life on Mars. Because meteorites in space absorb and record cosmic radiation, the time elapsed since the meteorite hit the Earth can be determined from laboratory studies. The elapsed time since fall, or terrestrial residence age, of a meteorite represents more information that might be useful in environmental studies of Antarctic ice sheets.
What is the answer to this question: What do meteorites absorb that can be used to understand how old the meteorite is?

So... cosmic radiation


Here is a question about this article: A culinary staple of North Carolina is pork barbecue. There are strong regional differences and rivalries over the sauces and methods used in making the barbecue. The common trend across Western North Carolina is the use of premium grade Boston butt. Western North Carolina pork barbecue uses a tomato-based sauce, and only the pork shoulder (dark meat) is used. Western North Carolina barbecue is commonly referred to as Lexington barbecue after the Piedmont Triad town of Lexington, home of the Lexington Barbecue Festival, which attracts over 100,000 visitors each October. Eastern North Carolina pork barbecue uses a vinegar-and-red-pepper-based sauce and the "whole hog" is cooked, thus integrating both white and dark meat.
What is the answer to this question: How many people visit the lexington Barbecue festival each year?

So... over 100,000


Here is a question about this article: Immigration of Czechs from Europe to the United States occurred primarily from 1848 to 1914. Czech is a Less Commonly Taught Language in U.S. schools, and is taught at Czech heritage centers. Large communities of Czech Americans live in the states of Texas, Nebraska and Wisconsin. In the 2000 United States Census, Czech was reported as the most-common language spoken at home (besides English) in Valley, Butler and Saunders Counties, Nebraska and Republic County, Kansas. With the exception of Spanish (the non-English language most commonly spoken at home nationwide), Czech was the most-common home language in over a dozen additional counties in Nebraska, Kansas, Texas, North Dakota and Minnesota. As of 2009, 70,500 Americans spoke Czech as their first language (49th place nationwide, behind Turkish and ahead of Swedish).
What is the answer to this question: What is the most commonly spoken non-English language at homes nationwide in the U.S.?

So...
Spanish
