Q: 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 "Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally."?
A: Which isotope appears first in the decay sequence, neptunium-237 or uranium-233?

Q: 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 "Alternative approaches, such as the British aid agency's Drivers of Change research, skips numbers and promotes understanding corruption via political economy analysis of who controls power in a given society."?
A: What is Driver's of Change's role?

Q: 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 "The term heartwood derives solely from its position and not from any vital importance to the tree. This is evidenced by the fact that a tree can thrive with its heart completely decayed. Some species begin to form heartwood very early in life, so having only a thin layer of live sapwood, while in others the change comes slowly. Thin sapwood is characteristic of such species as chestnut, black locust, mulberry, osage-orange, and sassafras, while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule. Others never form heartwood."?
A: What is it called when the heart is decomposed and becomes heartwood?

Q: 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 "Ski troops were trained for the war, and battles were waged in mountainous areas such as the battle at Riva Ridge in Italy, where the American 10th Mountain Division encountered heavy resistance in February 1945. At the end of the war, a substantial amount of Nazi plunder was found stored in Austria, where Hitler had hoped to retreat as the war drew to a close. The salt mines surrounding the Altaussee area, where American troops found 75 kilos of gold coins stored in a single mine, were used to store looted art, jewels, and currency; vast quantities of looted art were found and returned to the owners."?
A:
What area did they put the stolen items?
