Answer 1

Answer: Choice A

The conclusion is based on a voluntary response sample.

=======================================================

Further Explanation:

The people responding to the survey likely have strong opinions one way or another, and they may not represent the average population at large. This is especially true if the topic is controversial in nature.

The average person won't bother to take time to fill out the survey. So the surveys sent back will be from those who voluntarily pick themselves to send the surveys back. The results will likely be skewed in some way.

A better method would be to offer some kind of incentive so that even the average person is motivated to respond to the survey. The process of randomly selecting 1000 people is valid and doesn't need to be changed.
