To test the effects of a nitrogen fertilizer on cantaloupe production, researchers grew cantaloupe plants and harvested their fruit over three years. In each year, half the plants were grown using a nitrogen fertilizer, and the other half were grown using a control fertilizer that contained no nitrogen. The researchers concluded that the nitrogen fertilizer increases cantaloupe yield.

Which choice best describes data in the graph that supports the researchers' conclusion?

Question

Accepted Answer

In every year of the experiment, plants treated with the nitrogen fertilizer had a greater yield than did plants treated with the control fertilizer.

Answer

In every year of the experiment, plants treated with the nitrogen fertilizer had a yield of at least 30 pounds per acre.

Answer

The 2018 yield for plants treated with the control fertilizer was greater than was the 2019 yield for plants treated with the nitrogen fertilizer.

Answer

The yield for plants treated with the nitrogen fertilizer increased from 2017 to 2018.
