Answer to Question 1

C

Answer to Question 2

If one wants to draw conclusions from an experiment, one has to know that the study manipulates and validly measures the underlying psychological construct that he or she claims to be measuring and manipulating within the study. For example, if anxiety is the independent variable in a study, the researcher must be certain that the instrument validly measures anxiety and not some other construct.
