关于英语TPO17 阅读第二篇 的 一道题, 求助大家!
Paragraph 5: Less colorful birds and animals that inhabit the rain forest tend to rely on forms of signaling other than the visual, particularly over long distances. The piercing cries of the rhinoceros hornbill characterize the Southeast Asian rain forest, as do the unmistakable calls of the gibbons. In densely wooded environments, sound is the best means of communication over distance because in comparison with light, it travels with little impediment from trees and other vegetation. In forests, visual signals can be seen only at short distances, where they are not obstructed by trees. The male riflebird exploits both of these modes of signaling simultaneously in his courtship display. The sounds made as each wing is opened carry extremely well over distance and advertise his presence widely. The ritualized visual display communicates in close quarters when a female has approached.
10. What can be inferred from paragraph 5 about the less colorful birds and animals that inhabit the forest?
○These species are less able to see color. and therefore they communicate with one another using nonvisual signals.
○These species generally live in less densely wooded environments than more colorful birds and animals do.
○The cries of these species do not carry as well over distances as the cries of more colorful birds and animals.
○These species depend more on nonvisual signals for communication because they are less visible in their environment.
正确答案是D
可是D中的because they are less visible in their environment 在该段中哪里可以推断出来啊?
麻烦各位看一下,有劳了
