Read the following statements and choose the correct conclusion that can be logically inferred from these Statements.
Statements:
A. All bulls are bells.
B. Some bulls are cows.
C. Some bells are chairs.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Some bells are bulls.
“All bulls are bells” puts the whole circle of bulls inside the circle of bells. So the bells that are bulls exist, and “Some bells are bulls” follows by turning the first statement round. The diagram shows one way of drawing all three statements; a conclusion follows only if it is true in every such drawing.
Why the other options are incorrect
Option (1) All bells are cow. — Incorrect. Only some bulls are cows; nothing puts every bell among the cows.
Option (2) Some cows are chairs. — Incorrect. The chairs are linked only to some bells; the cows and chairs may not meet at all, as in the diagram.
Option (4) All bells are bulls. — Incorrect. All bulls are bells, but the bells circle can be larger than the bulls circle, so not every bell need be a bull.
