A

Answer to Question 2

A
Feedback:
Researchers do not always tell people they are being observed, because awareness of being observed may cause people to behave atypically. A behavioral distortion due to the known presence of an observer is called reactivity. It is not an ethical problem or lack of mobility. Acquiescence response set bias is a tendency to agree with statements regardless of their content by some people (yea-sayers). The opposite tendencyto disagree with statements independently of the question contentis less common.
