Q.

Fact 1:All dogs like to run.
Fact 2:Some dogs like to swim.
Fact 3:Some dogs look like their masters.
If the first three statements are facts, which of the following statements must also be a fact?
I:All dogs who like to swim look like their masters.
II:Dogs who like to swim also like to run.
III:Dogs who like to run do not look like their masters.                         
A. I only B. II only
C. II and III only D. None of the statements is a known fact.

Answer: Option B
Explaination:

 


Statement II is the only true statement. Since all dogs like to run, then the ones who like to swim also like to run. There is no support for statement I or statement III.
