A student conducted an experiment that used two rose plants to determine if a liquid formula for fertilizer was better than a dry formula. He tested each fertilizer on a single plant for one month, and he concluded that the liquid formula was better. When
he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked
for additional trials because
O she did not believe the new formula helped plants grow better than the old formula
O it was necessary to see data from more plants before the conclusion could be accepted.
O it was necessary to have tested the fertilizer on different kinds of plants.
O she thought he should test additional fertilizer formulas on the same two plants

In an experiment, conclusion can be made only after verifying all the results various times as difference in experimental conditions can leads to change in results.

As in given experiment, the student tested fertilizers only in a single plant and gave conclusion, but the result may change if  he performs that same experiment in a different plant or in a different experimental condition. Thus, his teacher most likely asked him for additional trail because 'it is necessary to observe data from various plants before making an conclusion that can be accepted.'
