Often the only discernible evidence an ornithologist has of the presence of certain birds is their song. This is also true for the birds themselves. Bird song serves as a means to mark nesting territory. The nature of bird song is influenced by the habitat. Low-pitched sounds travel better in areas of dense vegetation than high pitched sounds, which are common among birds nesting in open habitats. The timing and frequency of bird song are also controlled by hormones and thus are linked to the breeding season. In some species, only the male birds sing. The song of a male bird is thought to convey his fitness to female birds. A female bird may in turn use that information to select a worthy mate.
1. Which of the following statements could most logically follow the last sentence of the passage?
A. If birds were to use plumage to attract their mates, they would not need to use song for that purpose.
B. Female birds of one species are aware of the song of male birds of another species.
C. Therefore, bird song is not simply a matter of survival; it also provides entertainment.
D. Therefore, bird song may carry multiple meanings among birds.
E. Therefore, when birds with high-pitched sounds sing in the forest, their song signifies an open habitat or mating information.

Official Explanation
1. Which of the following statements could most logically follow the last sentence of the passage?
Explanation
Analyze the question stem
This is a variation on the classic Inference question. You are essentially asked to complete the passage with a logical conclusion or inference, based on the direction the author is taking.
Research
Review the last few sentences of the passage, considering what would logically come next, but also consider the scope and purpose of the passage since the next sentence will further the author's purpose in writing about the topic. The third-from-last sentence introduces the influence of hormones on bird song, and the last two sentences talk about male birds and female birds, respectively. In the third-from-last sentence, the word "also" is a continuation keyword; before this, the passage discusses the influence of habitat on bird song.
Make a prediction
A new sentence would help "explain the nature and functions of bird song," as stated in the purpose, and it would probably either summarize the information in the passage—different birds use song in different ways—or add yet another influence on bird song.
Evaluate the answer choices
(D) is correct; it summarizes the main idea of the paragraph.
(A) is unsupported. Plumage may be relevant to the ornithologist and to some birds in breeding season, but it is never mentioned in this passage. There is no evidence for its potential effect on bird song.
(B) is also unsupported; the last sentence of the passage is about females listening to male songs; however, there's nothing to indicate that it is an interspecies phenomenon.
(C) is incorrect because the entire discussion to this point has been about bird song as an adaptation for survival—to mark territory, to communicate in the surrounding habitat, to find a mate. No mention is made of entertainment.
(E) distorts details from the passage by making connections between them that the text doesn't support. High-pitched songs are common in open habitats, but that doesn't mean that the songs are intended to indicate the presence of such a habitat, and there's no connection mentioned between such songs and mating.
TAKEAWAY: Don't panic when you see an unusual question stem; think about what it's really asking and whether it fits into one of the standard question types.
