B). Not likely, because the sample size is too small.

C). Not likely, because a poll is only a snapshot of what people think at the time a poll is taken.

D). Yes, because the magazine has a national circulation and the sample size is sufficiently large.

Answer:

E). Not likely, because the sample is not random and thus probably not an accurate reflection of public opinion on the issue.
