Most Strongly Supported vs Weakening Questions

cillian-1-1-1-1

I was wondering what the main differences between most strongly supported questions and Weakening questions such as how to approach them?

Normal:

Strongly Supported:
- The Stimulus does not have an argument, but rather premises
- You have to find the conclusion of the argument in the answer choices

Weakening:
- The Stimulus has an Argument (Premises/Conclusion)
- You have to find the answer that weakens the support between the premises and conclusion in the answer choices

Causation and Phenomenon-Hypothesis:

Strongly Supported:
- The Stimulus has a phenomenon and hypothesis
- You have to find the answer that blocks out alternative hypothesis

Weakening:
- The Stimulus has a phenomenon and hypothesis
- You have to find the answer that is competing or corroborating with the hypothesis

Please let me know if this is wrong and how I can improve my understanding.

Thanks.
