Explanation:

A representative sample should be selected randomly and without bias to accurately reflect the entire population (adults in Canada in this case). Sample 2 is a convenience sample as it consists of only those who read the newspaper and choose to respond. This self - selection can lead to bias as not all adults in Canada are newspaper readers or survey responders.

Answer:

A. Sample 2 is a convenience sample limited to readers of the newspaper and is therefore likely to be biased
