Question
Two groups of students hypothesized that rocks on Earth’s surface are damaged by acid rain.
● Group X tested the hypothesis by examining properties of some rocks and pouring a weak acid, vinegar, on each of the rocks.
● Group Y later repeated the same procedure with a different group of rocks.
The rocks used for the investigations and the results from each student group are shown below.
Which of the following best describes an advantage Group X has over Group Y in supporting the hypothesis? SC.6.N.1.4
a
Group X tested the rocks before Group Y did.
b
Group X tested more rocks that are smoother.
c
Group X tested a greater variety of rocks than Group Y did.
d
Group X tested rocks with a greater average mass

The best answer is:
**c. Group X tested a greater variety of rocks than Group Y did.**
This option suggests that Group X's results are potentially more generalizable because they examined different types of rocks, which may provide stronger evidence to support the hypothesis regarding the effects of acid rain on rocks. The variety of rocks tested can help determine if the effects of acid rain vary based on rock type.
