Question

Suppose that a newspaper published the following in a
boxed corner of the want ads section:

Should handgun control be abolished? You can call the shots if
you participate in our poll tonight. If yes, call 1-900-For-Guns.
If no, call 1-900-Ban-Guns. You will be charged 50¢ for the
first minute.

Why will the results of this poll be biased?

Answer 1

Put yourself in the shoes of the caller and tell us what you think if you opt for the second choice.

Answer 2

Got it! Thank you!
