1. Which of the following best summarize the passage?
A. The diminishing numbers of chimney swift can be reversed by simple conservation efforts
This statement covers the main point of the passage: The number of these small, slender birds has decreased over the years due to habitat loss, but, since they are very adaptable, this situation can be reversed by doing simple conservation efforts, like keeping traditional masonry chimneys uncapped.
2. Which of the following can be inferred from the information in the passage?
D. The chimney swift's adaptability was severely hindered around 1970s
In the text, the author mentions that around this time the chimney swift populations started to decline sharply due primarily to habitat loss (Their environment was changed due to logging, deforestation, and the use of prefabricated chimneys), which help us infer that their adaptability was severely hindered around this time.
3. The first paragraph in the passage on chimney swifts includes this description: "...large colonies of hundreds, or even thousands, of individuals form tornado-like funnels." Why does the author include this in the passage?
B. It provides the reader with an engaging image
These words create a vivid picture in our mind that helps us see how the chimney swifts move.
4. Based on the passage, which of the following statements is true?
A. The author provides facts to support the main idea
To support the main idea, the author uses facts: he or she explains when the chimney swift population started to decline, and for what reasons (mainly due to deforestation, lodging, and prefabricated chimneys), and proves, with examples, how adaptable these birds are.
5. Which of the following lists support the main idea of the passage?
B. Logging and deforestation, changes in the ways we heat our buildings, and chimney capping have robbed the chimney swift of its preferred roosting sites.
The chimney swifts' preferred spaces to roost and nest are long, enclosed, hollow spaces, such as trees and chimney lined with clay, where they can cling to and make their nests, but the changes that we, as humans, have made in the environment, have robbed the chimney swift of its preferred roosting sites.
6. Which of the following conclusions can the reader make from the passage?
B. Chimney swifts can easily adapt roosting behaviors to any structure made of the proper material
When logging and deforestation started to take away from chimney swifts their preferred natural home, this species successfully adapted to chimneys lined with clay, where they could cling to and make their nests. From this, we can conclude that Chimney swifts can easily adapt roosting behaviors to any structure made of the proper material.
