I have a question about Q22. Section 2 (June 1997). I am trying to 'rule out' the wrong answer options based on the techniques from the logical reasoning bible. I understood the stimulus as following:
Prem: Some speculate that evolutionary pressure to increase diversity of gene pool causes unusually high frequency of small goats in island populations
Prem: However, in general reproductive success of a trait causes frequency of that trait in a population
Conclusion: Therefore, it is actually the case that 'reproductive success of small goats' causes unusually high frequency of small goats...
Question stem: the biologist's view, if true, provides the most support for which of the following?
A is a shell answer ('diverse gene pool' explanation is *not* the explanation of the biologist). B is an opposite answer. C is an opposite answer because it were true, than the biologist's view fails to explain why large goats, rather than small appear in greater frequency in these populations. E is out of scope.
1.-Is this ^ a correct application of the techniques in ruling out the wrong answers?
2. I am not sure exactly why D is correct is it because if we *assume the truth of the biologist's view* than the 'diverse gene pool' factor is *not* the cause of a greater frequency of small goats in these populations (instead the cause is reproductive success of these goats).
