The passage below is part of an article about evolution of birds. And I had to choose where the sentence:
“Furthermore, migration allows birds to avoid climates that are too hot or too cold during certain seasons.”
has to be placed in the paragraph.
A. Flight provides numerous benefits. B. It enhances hunting and scavenging; many birds consume flying insects, an abundant, highly nutritious food resource. C. Flight also provides ready escape from earthbound predators and enables some birds to migrate great distances to exploit different food resources and seasonal breeding areas. D.
I chose D as the answer without much thinking because it seemed like an obvious choice to me but the book says the answer is C. Can you explain to me why the sentence has to be inserted in C?
