Statements:

All computers are markers.

All erasers are markers.

All pens are erasers.

Conclusions:

I. No pen is a computer.

II. Some erasers are computers.

• A. Both conclusions I and II follow
• B. Only conclusion II follows
• C. Only conclusion I follows
• D. Neither conclusion I nor II follows

Answer 1
