Choose the set in which the third statement logically follows from the first two.
A. Dogs sleep in the open.
B. Sheep sleep indoors.
C. Dogs are like sheep.
D. All indoors are sheep.
E. Some dogs are not sheep.
F. Some open are not sheep.

Option A: AFE

Dogs sleep in the open and some open are not sheep. E need not follow these statements because there is a possibility that all dogs sleep in open that are sheep.

Option B: DCA

All indoors are sheep and dogs are like sheep. Statement A is unrelated to this. Hence, option B is wrong.

Option C: ABE
A and B contain 4 sets => Not related. Hence, E cannot be inferred.

=> None of these is the answer.
