Explanation:

Question 2

A field study involves observing subjects in their natural environment. The first option has a scientist investigating a mouse’s growth in nature by watching, which fits. Designing a tool (second) is about tool development, lab study (third) is controlled environment, and controlling food/exercise (fourth) is an experiment, not field study.

Variation means differences. "Different" relates to variation (showing differences). "Consistent" and "similar" imply sameness, and "untrustworthy" is about reliability, not variation.

Answer:

A. A scientist investigates a mouse’s growth in nature by watching the animal.
