Researchers studying long-term changes In regional mouse populations have found that by focusing on the populations of a rare but widespread and easily identifiable species of mouse (Species X), they can make fairly accurate estimations about the total regional mouse populations.

In a report on a recent study that Included the data tables that follow, the researchers provided some addenda:

1.

"The Species X population of Region CV increased by 123,995 between 1990 and 2005.

2.

In contrast, the Species X population of Region EW declined by about 52% during that same time.

The answer to which one of the following can be determined by using the information in the passage and tables?

A. Between 1990 and 2005, did the Species X population of EW decrease by a greater number than the Species X population of CV increased?

B. What was the approximate total mouse population of ]R in 2005?

C. Did the Species X population of IQ increase between 1990 and 2005?

D. Was the approximate total 2005 mouse population of TY larger or smaller than that of EW?

E. What caused the Species X population of TY to increase so dramatically between 1975 and 1990?
