   Insects that collect pollen from primroses do not discriminate between self-pollinating primroses

   This doesn't provide any reason for why self-pollinating primrose are less prevalent than non-self-pollinating primrose. In fact, it doesn't make any distinction between the two types of primrose at all.

   When insect pollinators are scarce, non-self- pollinating primroses produce larger seeds that are more likely to germinate than

   Why this is right

   This gives us a way to explain why self-pollinating primrose are less prevalent than non-self-pollinating primrose. Even though the self-pollinating primrose produce more seeds than the non-self-pollinating primrose do when pollinators are scarce, the seeds produced by the self-pollinating primrose are smaller and less likely to germinate. This explains how there could be more seeds of type X but fewer plants of type X -- the seeds from plant X don't end up sprouting and growing.

   Self-pollinating primroses that are located in areas with few insects produce no fewer seeds than do self-pollinating primroses that are located

   This tells us about a specific context in which self-pollinating primroses don't produce fewer seeds. Okay. Well then this won't help us explain why there are fewer self-pollinating primroses.

   Many primroses are located in areas in which the soil conditions that are optimal for seed

   This doesn't provide any reason for why self-pollinating primroses are less prevalent than non-self-pollinating primroses, because it doesn't make any distinction between the two types of primroses at all.

   Self-pollinating primroses can be assisted by insects during pollination but do not require the assistance of

   This tells us that self-pollinating primroses are sometimes assisted by insects. So that won't help us explain why there are fewer self-pollinating primroses. We need to hear something that's harder / worse / negative for self-pollinating primroses.
