Question 1 of 10

1. Question

The primary purpose of the passage is to

examine how experiment data counters a hypothesis about bat behavior.
Correct Incorrect Correct answer

reveal how the data from an experiment can inform biological conservation.
Correct Incorrect Correct answer

analyze the results of an experiment that shows a how bats in the wild behave.
Correct Incorrect Correct answer

evaluate the effect of research on how chemical cues and foraging relate to bats.
Correct Incorrect Correct answer

Correct

Incorrect
Question 2 of 10

2. Question

Information in paragraph 1 (lines 1-15) indicates that bats’ chemical attraction to scent might

be detrimental to their livelihood due to the scent luring them to places full of predators.
Correct Incorrect Correct answer

benefit the bat population since scientists can lead bats to roost in safe locations.
Correct Incorrect Correct answer

decrease their frequency of moving roosts regardless of guano or urine.
Correct Incorrect Correct answer

improve bat population in roosts since population density is a key conservation issue.
Correct Incorrect Correct answer

Correct

Incorrect
Question 3 of 10

3. Question

Based on information presented in the passage, it can most reasonably be inferred that

bats rely on chemical and scent cues to find new habitats.
Correct Incorrect Correct answer

bats do not rely on scent cues for any aspect of their lives in the wild.
Correct Incorrect Correct answer

there is little correlation between bats’ use of scent cues and their roost determination.
Correct Incorrect Correct answer

further study is required to determine whether urine or guano influence bat roosting behavior.
Correct Incorrect Correct answer

As used in line 74, “aversion” most nearly means

dislike
Correct Incorrect Correct answer

attraction
Correct Incorrect Correct answer

Question 7 of 10

7. Question

Which finding about bats’ use of guano, if true, would best support the experiment results from the passage?

Bats’ roost location is determined by chemical rather than social cues.
Correct Incorrect Correct answer

Bats tend to use chemical cues in some aspects of their lives, but not for all situations.
Correct Incorrect Correct answer

Bats determine safety of a roost location by the absence of scent cues.
Correct Incorrect Correct answer

Bats’ use of chemical cues are determined by their previous residence.
Correct Incorrect Correct answer

Correct

Incorrect
Question 8 of 10

8. Question

Which choice provides the best evidence for the answer to the previous question?

Lines 57-59 (“By contrast\(\ldots\)locations.”)
Correct Incorrect Correct answer

Lines 59-62 (“The attraction\(\ldots\)scent.”)
Correct Incorrect Correct answer

Lines 63-65 (“Despite the\(\ldots\)roosts.”)
Correct Incorrect Correct answer

Lines 68-70 (“Hence, our\(\ldots\)low.”)
Correct Incorrect Correct answer

Correct

Incorrect
Question 9 of 10

9. Question

Which statement is best supported by the passage and the data in the figure?

Only one species of bat shows bias to scented roosts.
Correct Incorrect Correct answer

Bat populations show a mean scent bias of 0.5.
Correct Incorrect Correct answer

Bat species do not overall show a significant preference for scented roosts.
Correct Incorrect Correct answer

In Experiment 2, bat species visited scented roosts a mean number of 75 times.
Correct Incorrect Correct answer

Correct

Incorrect
