Answer to Question 1

ANS: B

Feedback
A The wide availability of subjects could positively affect the feasibility of the study.
B Feasibility refers to the pragmatic considerations of a study (e.g., availability of subjects, cost).
C Informed consent for children would not affect availability of subjects.
D Lack of previous studies would suggest a need for the study but does not influence feasibility.

Answer to Question 2

ANS: A

Feedback
A An extraneous or mediating variable is one that interferes with the operations of the variables being studied, such as the study's outcome, which is susceptibility to influenza.
B A subject's knowledge of vitamin C's functions is not likely to act as a mediating variable in this study.
C The gender of participants is not likely to act as a mediating variable in this instance.
D The marital status of subjects is not likely to act as a mediating variable in this scenario.
