Hi
KarishmaB MartyMurray GMATNinjaIf we slightly tweak the option (B) in question-3 by inserting "an", would it be the correct answer then?
3. The first paragraph primarily performs which of the following functions in the passage?B. It explains how "an" environmental damage can cause effects that last for generations.My reasoning is "an environmental damage" would refer to the condition given in the passage that reduces oxygen levels. I think original (B) generalises "environmental damage", hence, incorrect.
Please let me know.
I think it still would not be correct.
Even with “an environmental damage,” option B would still be wrong because the first paragraph does
not explain effects that last for generations. It focuses on immediate consequences of hypoxia: escape to unsafe habitats, increased predation risk, and reduced fertility. Long-term or generational effects are introduced only in the second paragraph, when gene function, sex ratios, and population survival are discussed.
So the problem with B is not just over-generalization. It is that the
time scale described in the option does not match what the first paragraph actually does.
