Possible error in k6-learn parallel requests Test Question

[hayone1]

In the k6-learn parallel requests section, there's a question there
that goes thus.

Question 3

When might you not want to use parallel requests?

A: When you want to increase the number of requests your test is sending

B: When you have requests using multiple types of HTTP methods

C: When you're testing API endpoints

And the answer given is this which I think is at variance with the "not" in the question:

3. A. The key here is your objective, not what you're testing. If you want to increase your test throughput (the number of requests sent by k6), parallel requests would be a valid way to do that. Whether you're using multiple HTTP methods or testing API endpoints is beside the point.
