Answer: (A) Surveys are generally cheaper to conduct.
Explanation:
Both surveys and experiments are valid means to scientifically establish data about groups of people and how the way specific variables influence them. A survey examines the way a variable we have no control over has affected, for example, a group of people. In an experiment, one of the variables is manipulated while the other one is measured.
Surveys are comparatively inexpensive, especially if they are online surveys, and even if incentives are provided to participants.
Committees are necessary in Congress because committee members play key roles in floor debates about the bills that they foster.
Committees help to organize the most important work of Congress considering, shaping, and passing laws to govern the nation.
