Answer:

A) Bright lights will keep more students awake in class than dimmer lights.

Explanation:

Professor Boredom's hypothesis in this example is that<em> bright lights will keep more students awake in class than dimmer lights</em>. In this example, Professor Boredom is blaming sleepy students on lights. Lights are the independent variable that he can manipulate to find the number of sleepy students. The number of "sleepy students after the lecture" is according to Professor Boredom, the dependent variable that responds to the independent variable the "amount of light".
