The passage below describes an experiment.

a paper clip floating on water

Karen filled four cups with equal amounts of water. She added nothing else to the first cup, one drop of detergent to the second cup, two drops of detergent to the third cup, and three drops of detergent to the fourth cup. Then, she laid paper clips one at a time on the surface of the water in the first cup and recorded how many floated. She repeated this procedure with the remaining cups.

Identify the question that the experiment can best answer.

Does the amount of detergent added to water reduce its ability to support paper clips on its surface?

Does water dissolve more salt when it has detergent in it?
