Question:

Answer:
It seems to be a difficult one to read and understand. Never mind, look at the options and eliminate one by one:
Rupert Baxter was Lord Emsworth's former secretary not current one, 
So [2] is eliminated, 
[4] implies the opposite of what is said in passage. 
The passage talks only about Lord Emsworth's dislike of Rupert Baxter, and not vice versa, so [1], which states that they both disliked each other, is incorrect. 
Hence, [3].
