Here is a question about this article: Uranium-238 is the most stable isotope of uranium, with a half-life of about 4.468×109 years, roughly the age of the Earth. Uranium-235 has a half-life of about 7.13×108 years, and uranium-234 has a half-life of about 2.48×105 years. For natural uranium, about 49% of its alpha rays are emitted by each of 238U atom, and also 49% by 234U (since the latter is formed from the former) and about 2.0% of them by the 235U. When the Earth was young, probably about one-fifth of its uranium was uranium-235, but the percentage of 234U was probably much lower than this.
What is the answer to this question: What is the half-life of uranium-234?
****
So... 2.48×105 years


Here is a question about this article: Resorting to this verbal device, however, did not protect the "Ancient Near East" from the inroads of "the Middle East." For example, a high point in the use of "Ancient Near East" was for Biblical scholars the Ancient Near Eastern Texts relating to the Old Testament by James Bennett Pritchard, a textbook of first edition dated 1950. The last great book written by Leonard Woolley, British archaeologist, excavator of ancient Ur and associate of T.E. Lawrence and Arthur Evans, was The Art of the Middle East, Including Persia, Mesopotamia and Palestine, published in 1961. Woolley had completed it in 1960 two weeks before his death. The geographical ranges in each case are identical.
What is the answer to this question: Who excavated ancient Ur?
****
So... Leonard Woolley


Here is a question about this article: In 2010, bills to abolish the death penalty in Kansas and in South Dakota (which had a de facto moratorium at the time) were rejected. Idaho ended its de facto moratorium, during which only one volunteer had been executed, on November 18, 2011 by executing Paul Ezra Rhoades; South Dakota executed Donald Moeller on October 30, 2012, ending a de facto moratorium during which only two volunteers had been executed. Of the 12 prisoners whom Nevada has executed since 1976, 11 waived their rights to appeal. Kentucky and Montana have executed two prisoners against their will (KY: 1997 and 1999, MT: 1995 and 1998) and one volunteer, respectively (KY: 2008, MT: 2006). Colorado (in 1997) and Wyoming (in 1992) have executed only one prisoner, respectively.
What is the answer to this question: Since 1976, how many prisoners has Nevada executed?
****
So...
12
