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)

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

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.

If the conclusion contains a generalization, then a possible strengthener will show another instance in which the generalization holds true. A weakener, on the other hand, will show another instance in which the generalization does not hold true. Hence (C) is the right answer.

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

Option C never says about south and is not a good contender for answer. It does not give thought whether Jays cannot travel to south with out help.

Option E says Crookbeaks travel with out Jays, means Jays may or may not require some one to take them to North but they require some one to take to South.

Not able to understand how Option C is better than Option E.

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

If crookbeaks migrate before Crotons , we cannot state whether Croton will reach their destination/not, hence this doesn't strengthen the conclusion...

To strengthen the conclusion " Croton's jays lack the navigational ability to find their way south on their own." we need a statement to show that the Crotons are dependent on the crookbeaks for navigation/migration and only (C) does it perfectly.

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

As mentioned in the passage, Croton's jay is dependent on crookbeaks for migration to south.
If we are able to find some clue which suggests that the Croton's jay needs the same kind of help in migration, then that will help to strengthen the argument.
option (C) suggests the same.

B. The three species most closely related to crookbeaks do not migrate at all.
out of scope
C. In the spring, Croton's jays migrate north in the company of Tattersall warblers.
Correct choice that strenthens the conclusion of the argument that says that Croton's jays lack navigational ability.
D. Species other than Croton's jays occasionally accompany flocks of migrating crookbeaks.
Out of scope
E. In the spring, crookbeaks migrate north before Croton's jays do.
weakens the argument

Which of the following, if true, most strengthens the argument above?

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

(B) The three species most closely related to crookbeaks do not migrate at all.

(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.

Looking to strengthen the argument that Croton's Jays don't have the navigational abilities to migrate south on their own.

(A) Croton's jays lay their eggs in the nests of crookbeaks, which breed upon completing their southern migration.
Eliminate- this doesn't relate to the question of migration or navigational abilities but instead gives an alternate reason why jays might follow crookbeaks.

(B) The three species most closely related to crookbeaks do not migrate at all.
Eliminate-irrelevant, only interested in Croton's Jays so this information doesn't help us strengthen or weaken the argument.
(C) In the spring, Croton's jays migrate north in the company of Tattersall warblers.
keep-gives us evidence that the Croton's Jays can't migrate without assistance
(D) Species other than Croton's jays occasionally accompany flocks of migrating crookbeaks.
Eliminate-irrelevant because we are only looking info on Croton's Jays, not other birds

(E) In the spring, crookbeaks migrate north before Croton's jays do
Eliminate because argument specifies southern migration, not northern migration. Leaves open the option that the jays can navigate north on their own or could follow another type of bird. Looking for info specifically on Croton's Jays, not Crookbeaks.

Isn't north thing is out of scope? It is given that in conclusion that Croton's jays lack ability to find their way south. If they would have mentioned in any direction than north can be used, but for south I guess the option C is out of scope? Please clear my doubt here
