Professor Gordon finds that students who read newspapers daily display more knowledge of current events than students who do not read newspapers daily. What type of evidence does this identification of a cause of behavior exemplify? A. Cognitive awareness B. Temporal precedence of cause C. Covariation of cause and effect D. Elimination of alternative explanations

C. Covariation of cause and effect

Explanation:

When there are two variables and it is established that one variable is the cause and the other variable is the effect, the process of establishing this is known as covariation of cause and effect.

Here, the variables are the students who read newspaper and the knowledge they posses. It can be seen that those who read newspaper have more knowledge. The cause and effect relation has been established.

Hence, the question is referring to covariation of cause and effect.
