Croton's jays lack the navigational ability to find their way south on their own.

C - In the spring, Croton's jays migrate north in the company of Tattersall warblers.

Although the solution to the above problem can be reached through POE,option C tells about the migration to north and not to the migration to south(as stated by the conclusion)

This sentence is correctly strengthening since this indicates that Croton's jays migrate north before they migrate again to south with the crookbeaks, requiring assistance in both the travels.

Every fall Croton's jays migrate south. The jays always join flocks of migrating crookbeaks with which they share the summer and winter territories. If a jay becomes separated from the crookbeaks it is accompanying, it wanders until it comes across another flock of crookbeaks. Clearly, therefore, Croton's jays lack the navigational ability to find their way south on their own.

Which of the following, if true, most strengthens the argument above?
A - Croton's jays lay their eggs in the nest of crookbeaks, which breed upon completing their southern migration.
B - The three species of most closely related to crookbeaks do not migrate at all.
C - In the spring, Croton's jays migrate north in the company of Tattersall warblers.
D - Species other than Croton's jays occasionally accompany flocks of migrating crookbeaks.
E - In the spring, crookbeaks migrate north before Croton's jays do.

What need to find = most strengthens the argument above

conclusion words ----clearly , therefore

Conclusion ----. Clearly, therefore, Croton's jays lack the navigational ability to find their way south on their own.

Need to emphasis on conclusion ----let's discuss each given statement

A - Croton's jays lay their eggs in the nest of crookbeaks, which breed upon completing their southern migration.

conclusion is on navigational ability to find the way in the argument , which needs to be strengthens ,while statement A emphasis on the habit of CJ laying eggs in the nest of crookbeaks

B - The three species of most closely related to crookbeaks do not migrate at all.

Premises is about only CJ and Crookbeaks , which are specific in the argument , while three species are general ---not related to argument

C - In the spring, Croton's jays migrate north in the company of Tattersall warblers.

migrate north in the company ------Croton's jays lack the navigational ability to find their way south on their own , means CJ Needs company to reach ----strength

D - Species other than Croton's jays occasionally accompany flocks of migrating crookbeaks.

Species other than Croton's-----out of scope , argument is about CJ

E - In the spring, crookbeaks migrate north before Croton's jays do.

look at word ---Before ---To strengthen we need together or accompany
