The Cycles of Matter

Question 6 • Environmental Science A

In what way do investigations build scientific knowledge?

Answer

The results of investigations lead to questions that cannot be tested.

They reflect the opinions and social values of scientists, ensuring valid information.

The results of investigations lead to new questions, which lead to new investigations.

They are not influenced by the research of earlier scientists, so they are able to address gaps in understanding.

Explanation

Investigations build scientific knowledge through an ongoing cycle: evidence from one investigation raises new questions, and scientists investigate those questions to learn more. This matches choice C, “The results of investigations lead to new questions, which lead to new investigations.” Scientific investigations are designed to test questions, and they often build on earlier research rather than ignoring it.
