Given a scientific passage and an answer, generate a question for the given answer.

[EX Q]: Passage: Many samples have a lot of variation in measurements. Variation can be described with a statistic called the range. The range is the total spread of values in a sample. It is calculated by subtracting the smallest value from the largest value. Answer: range
[EX A]: What term is used to describe the total spread of values in a sample?

[EX Q]: Passage: When two plates of continental crust collide, the material pushes upward. This forms a high mountain range. The remnants of subducted oceanic crust remain beneath the continental convergence zone. Answer: high mountain range
[EX A]: When two plates of continental crust collide, the material pushes upward and forms what?

[EX Q]: Passage: When plates are pushed or pulled, the rock is subjected to stress. Stress can cause a rock to change shape or to break. When a rock bends without breaking, it folds. When the rock breaks, it fractures. Mountain building and earthquakes are some of the responses rocks have to stress. Answer: stress
[EX A]:
Mountain building and earthquakes are some of the responses of rocks when subected to what?
