Question

practice it! which of the following is a benefit of descriptive investigation? able to study topics that experiments cannot test results repeated and verified does not have variables includes a conclusion

Explanation:

• Analyze each option:
• "able to study topics that experiments cannot test": Descriptive investigations are used to describe phenomena and can study topics where experimental manipulation is not feasible (e.g., studying natural ecosystems in their natural state, or historical events). This is a key benefit as experiments have limitations in testing certain real - world or non - manipulable scenarios.
• "results repeated and verified": This is more characteristic of experimental investigations where controlled conditions allow for replication. Descriptive investigations often lack the control needed for easy replication.
• "does not have variables": All scientific investigations involve variables (even descriptive ones, as they describe characteristics which are variables). So this is incorrect.
• "includes a conclusion": All types of investigations (descriptive, experimental, etc.) aim to draw conclusions, so this is not a unique benefit of descriptive investigation.

Answer:

A. able to study topics that experiments cannot test
