Read the descriptions of two experiments below.
Experiment 1: A group of students did a test to see if the
acidity of water affects the growth of pea plants. They
followed a logical method and performed their experiment
once, using a control group and experimental groups. The
results supported their hypothesis.
Experiment 2: A group of students did a test to see if the
acidity of water affects the growth of bacteria in the water,
They used a control group and experimental groups. They
repeated their experiment several times and received the
same results each time.
Which experiment is more likely to be reliable, and why?
O A. Experiment 2, because it gave the same results every time
O B. Experiment 1, because its results supported the hypothesis
O C. Experiment 1, because it followed a logical method
O D. Experiment 2, because its setup included a control group
