Correct me if I am wrong in my explanation.

The kind of question this is: Weakening

Paraphrased question:

Premises: In North Atlantic, Codfish population declined as population of Harp seals increased from two mil to three mil, so there is blame on the seal for Codfish decline, but Cod plays a negligible role in Seal’s diet.

Conclusion: Therefore, it is unlikely seals are responsible for the decline of codfish.

What I am looking for: Something I didn’t know about the correlation between Cod decrease and seal increase. (broad lol).

Answer A: No, this doesn’t weaken the argument. It’s not about how people are inconvenienced about fish because of the seals, its about Cods and Seals.

Answer B: No, but sure, there could be a threat. But, there is no information saying that Codfish are dying from this so-called threat. And, what kind of threat is it anyways?

Answer C: No. Sure they capable enough to thrive in water that cod can’t swim in, but that doesn’t mean they can only live in that type of water. They can swim to warmer water to catch cod if they wanted to.

Answer D: Yes, because if Cod feed almost exclusively on capelin, which is a staple diet for seals, then they must run into each other a lot underwater. Or maybe where you find capelin, you will find Cods, and Cods happen to get eaten too.

Answer E: No, that strengthens the argument because it suggests that the seals have nothing to do with the cod decrease.

    yes. plus the seals are sharing the food supply, leading to population decrease for cod.
