Answer:A

Explanation:

A soft drink will definitely be a poor comparison menu because it initially started the experiment with a bacon cheeseburger. From the experiment, it doesn't correlate with the representativeness.

Answer: a. ​soft drink sales

Explanation: A poor comparison item would be the soft drink sales. For a sample unit to be representative, all of the elements in a population should have the same chance to be part of the larger sample. A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. All other options are in a way similar to the bacon cheeseburger except soft drink sales. Therefore it is not representative of the whole.
