Which step will they most likely complete as part of this investigation?

Collect and observe soil from different areas of the community.
Test the texture of one sample of soil.
Investigate a property of soil using a control group.
Observe the pH of a common type of local soil.

Answer:

Collect and observe soil from different areas of the community

Explanation:

Since the investigation is comparative (key word), it will be necessary to compare different kinds of soils. Testing one soil would not work for this. You need more than one test sample!
