An experiment was conducted to determine which type of fruit attracts the most fruit flies. Equal sized pieces of apple, pear, and banana were placed in separate containers at different areas around the school. The containers allowed the fruit flies to enter, but the fruit flies were unable to escape. After one day, observations were made by the students. Which best describes an error the students made in the experiment? A) too many types of fruit were used B) fruit flies were unable to escape C) different areas around the school were used D) one day is not long enough for the experiment

C

Explanation:

The error that the student made was to place the containers for the different fruits in different areas around the school.

In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.

The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.

The correct option is C.
