“Native to the coastal swamps of the Carolinas, Venus fly traps attract insects by secretion of sweet nectar and spring shut in less than a tenth of a second, digesting the prey thoroughly enough that only dried skin fragments remain when its sealed stomach opens again ten days later.”
A. Venus fly traps attract insects by secretion of sweet nectar and spring shut in less than a tenth of a second, digesting the prey thoroughly enough
B. Venus fly traps attract insects by secretion of sweet nectar, they spring shut in less than a tenth of a second, and with such thorough digestion of the prey
C. Venus fly traps use secretion of sweet nectar to attract insects, spring shut in less than a tenth of a second, and digest the prey so thoroughly
D. the Venus fly trap attracts insects by secretion of sweet nectar, springing shut in less than a tenth of a second and digesting the prey so thoroughly
E. the Venus fly trap attracts insects by secretion of sweet nectar, springs shut in less than a tenth of a second, and it digests the prey thoroughly enough
I know this is an old topic, but I think this problem is important to understand.
When you read the first sentence and then decide where to start, the best place to look is sometimes the non-underlined portion. Here, the non-underlined portion gives a HUGE signal: "when
its stomach opens again" shows that the noun HAS to be singular. Just noticing this eliminates answers A, B, and C ("Venus fly traps" is plural).
Between D and E, the decision point is mostly between "digesting the prey so thoroughly" and "digests the prey thoroughly enough". The latter is grammatically incorrect ("thoroughly enough that" is very wrong), and leaves answer D remaining.
A takeaway from this is to look at the non-underlined portion when you start. Often, as in this problem, the non-underlined portion is essential to determine decision points.
Hope this makes sense.
