N.A Defender Type Answer Choices and Strengthen Eliminating the Weakness Answer Choices
I somehow feel that those two answer choices are very similar. Does anyone here have opinion on how those two answer choices differ? Those question types are both assumption type questions, and I assume that is why I feel those two are from similar (not the same) grounds.
For example, this is an made up argument but...
Assumption: This september, there are more people coming to watch movie in theatre A.
Conclusion: Therefore, theatre A would collect more profit this month.
Strengthen (Eliminating the Weakness AC) and NA AC could be both something like the theatre did not offer large price discount this September.
Effect (Premise): Five species of coral in the bay, including the mounds that existed for 200 years died.
Cause(Conclusion): Therefore, the blackwater incident was more serious and intense than before.
Answer Choice (D): (Defender AC) the mounds that existed for 200 years was "not" weaker last year than before.
Weakener: the mounds that existed for 200 years was weaker last year than before. (Alternative Explanation); If this is true, then the entire argument falls apart because Causation Logic is destroyed by exploring other sets of alternative explanations.
