QUESTION TEXT: Unlike other primroses, self-pollinating primroses do…
QUESTION TYPE: Paradox
PARADOX: Self-pollinating primroses produce more seeds, but they’re rarer than non-self-pollinating primroses.
ANALYSIS: Self-pollinating primroses obviously have the advantage of having more seeds. But that’s probably not the only factor.
We need to find an advantage for non-self-pollinators, or a disadvantage for self-pollinators.
___________
- So? Self-pollinating primroses don’t need insects, so it shouldn’t matter if insects visit self-pollinating primroses.
- CORRECT. This shows that the number of seeds is not the only factor. Non-self-pollinators produce fewer seeds, but their seeds are more likely to grow.
- This tells us that insects aren’t a factor for self-pollinating primroses. So what? This does nothing to explain why there are fewer self-pollinating primroses, despite their higher seed count.
- This doesn’t distinguish between the two types of primroses. Useless.
- This gives a further advantage to self-pollinating primroses, making the situation even more confusing.
