Use the Following Research Scenario to Answer the Next Four

Use the following research scenario to answer the next four questions:
A researcher was interested in the effects of 1) alcohol consumption and 2) content of a videotape, on how likely one is to support rape myths.  The researcher randomly assigned 60 college-aged males to one of the following three groups: no alcohol consumed, a moderated amount of alcohol consumed, and a large amount of alcohol consumed.  Additionally, half of the participants were shown the educational video on rape myths. The other half of the participants watched a documentary on owls (a control condition) .  At the end of the study all the participants filled out a survey on rape myth acceptance.  Higher scores on the survey indicated higher acceptance of rape myths.
What would you suggest if the researcher found that alcohol consumption increased rape myth acceptance, but only when the participants had watched the owl video?

A) There is an interaction between alcohol consumption and video type.
B) There is a main effect of alcohol consumption.
C) There is a simple effect of alcohol in the educational video condition.
D) There is a main effect of the video condition.
