A researcher did an experiment testing the effects of noise on students' ability to study effectively in different environments.There were three levels of background noise and two different environments so the design was a 3 × 2.The researcher obtained an interaction effect and decided to try to identify the source of the interaction effect by testing the effects of the noise variable separately at each level of the environment variable.Which of the following types of effects in the analysis of a complex design was the researcher testing?
A)main effect
B)simple main effect
C)moderator effect
D)comparison of two means

The researcher is testing the simple main effect, which is the effect of one independent variable at a specific level of another independent variable. In this case, the researcher is testing the effect of noise at each level of environment separately, which is a simple main effect.
