Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators. In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.

B. large moths are proportionally much more common in warm climates than in cool climates
This option talks about why more larger moth are present in warm climates compared to cool climates as larger moth has higher optimal temperatures -> Correct

kinjiGC thanks for the explanation

I feel there is no Logically connectivity when B is plugged and the sentence is read as a whole.

In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why large moths are proportionally much more common in warm climates than in cool climates.

Generally BUT is used to spot out contradictions : Ex: I walk very fast , but I cannot Run.

Which of the following most logically completes the passage?

In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why _______.

(A) large moths are generally able to maneuver better in flight than smaller moths

(B) large moths are proportionally much more common in warm climates than in cool climates

(C) small moths are more likely than large moths to be effectively camouflaged while on vegetation

(D) large moths typically have wings that are larger in proportion to their body size than smaller moths do

(E) most predators of moths prey not only on several different species of moth but also on various species of other insects

IMO, straight B.

Only B that contains and have the relationship with the "temperature".
