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 "The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place."?

A: What did the elimination of wolves do to hydrology?

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 "Until the 1950s guns firing ballistic munitions were the standard weapon; guided missiles then became dominant, except at the very shortest ranges. However, the type of shell or warhead and its fuzing and, with missiles the guidance arrangement, were and are varied. Targets are not always easy to destroy; nonetheless, damaged aircraft may be forced to abort their mission and, even if they manage to return and land in friendly territory, may be out of action for days or permanently. Ignoring small arms and smaller machine-guns, ground-based air defence guns have varied in calibre from 20 mm to at least 150 mm."?

A: Which were developed first, ballistic munitions or guided missiles?

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 "Since the show's inception in 2002, ten of the fourteen Idol winners, including its first five, have come from the Southern United States. A large number of other notable finalists during the series' run have also hailed from the American South, including Clay Aiken, Kellie Pickler, and Chris Daughtry, who are all from North Carolina. In 2012, an analysis of the 131 contestants who have appeared in the finals of all seasons of the show up to that point found that 48% have some connection to the Southern United States."?

A: How much of a connection do winners have to being from the Southern United States?

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 "According to Vetter, the description of the Buddhist path may initially have been as simple as the term "the middle way". In time, this short description was elaborated, resulting in the description of the eightfold path."?

A:
What is the description for remaining pathway of three total, where two veer off either left and right?
