Answer to Question 1

C

Answer to Question 2

Randomization allows each subject to have an equal chance of being selected. Selection of an analogue or clinical sample limits our conclusions/generalizations based on the nature of the sample. The diversity of the sample would also limit this. Internal validity is affected by the degree to which confounding influences are controlled. As internal validity increases, external validity may decrease because the sample may not reflect conditions in the real world. Finally, the expectations of both the researcher and the subjects (blindedness) may confound the results and our interpretation of them.
