If the awareness of a pretest poses a problem, the researcher may opt not to inform participants of the pretest. This means that the researcher is least likely to tell the participants what is being studied and why, as indicated in option D. Disguising the pretest (option A) or embedding it in a set of irrelevant measures (option B) are strategies that could be employed to minimize the awareness of the pretest. A Solomon four-group design (option C) involves using two groups (one with a pretest and one without) and two control groups (one with a posttest only and one with neither pretest nor posttest) to test the effect of pretesting. While this design can be used to address the problem of pretest awareness, it is not the least likely option.
