Question

Fact $1$: Pictures can tell a story.
Fact $2$: All storybooks have pictures.
Fact $3$: Some storybooks have words.
If the first three statements are facts, which of the following statements must also be a fact?
I: Pictures can tell a story better than words can.
II: The stories in storybooks are very simple.
III: Some storybooks have both words and pictures.

• A. I only
• B. II only
• C. III only
• D. None of the statements is a known fact.

Answer 1

The correct option is C III only

Statements I and II are not supported by the facts. Statement III is true because if all story-books have pictures and only some have words, then some storybooks have both words and pictures.
