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 1

Answer: (B)

II only

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.
