I think the answer would be D, since you are not allowed to drive between the hours of 11pm to 5 am. Hope it helps!
I don't see a link, can you state the question and then I can help you please?
Extraneous
An <em>extraneous variable</em> is a variable in an experiment that you are not intentionally studying. These variables usually provide undesired affects on the experiment.
In this example, the independent variable is whether a sentence is humorous or not, and the dependent variable is the memory performance score. However, because the humorous sentences are only given to males, and the non-humorous sentences are only given to females, gender becomes an extraneous variable as you are not intentionally testing gender's relation to the dependent variable, but it is still affecting the experiment.
