Question

nest survival by site
adapted from l. mckinnon et al., \lower predation risk for migratory birds at high latitudes.\ ©2010 by american association for the advancement of science.
the figure shows the results for the nesting 19 sites, furthermore, at four of the seven locations, averaged over the four years of the study. the 20 number of predators invading the nests increased over time at each location. this result confirmed that predators were present at the researchers chosen locations. the researchers found that the percent of 21 surviving nests was greater at locations having higher latitudes. for example, on day 9, approximately 55 percent of nests were found to have survived at the 82°n location compared to approximately 10 percent of nest survival at the 63°n location.
19
a) no change
b) sites
c) sites, however;
d) sites, in addition.
20
which choice makes the writers description of data represented in the figure most accurate?
a) no change
b) numbers of predators invading the nests decreased
c) percent of surviving nests decreased
d) percent of surviving nests increased
21
which choice makes the writers description of data represented in the figure most accurate?
a) no change
b) surviving nests was smaller
c) surviving nests remained the same
d) eggs was much lower

Explanation:

1. "sites, however," is the most appropriate as it indicates a contrast in the text. The previous and following sentences have a contrasting relationship.
2. The graph shows that the percent of surviving nests decreased over time, so "percent of surviving nests decreased" is the accurate description.
3. The text mentions that the percent of surviving nests was greater at higher - latitude locations. So, the original "NO CHANGE" is correct as it aligns with the data presented.

Answer:

1. C. sites, however;
2. C. percent of surviving nests decreased
3. A. NO CHANGE
