Question

Directions for questions: Each question has a set of four statements. Each statement has three segments. Choose the alternative where the third segment in the statement can be logically deduced using both the preceding two, but not just from one of them.

A. A few farmers are rocket scientists. Some rocket scientists catch snakes. A few farmers catch snakes.
B. Poonam is a kangaroo. Some kangaroos are made of teak. Poonam is made of teak.
C. No bulls eat grass. All matadors eat grass. No matadors are bulls.
D. Some skunks drive Cadillacs. All skunks are polar bears. Some polar bears drive Cadillacs.

• A. C and D
• B. A and C
• C. C only
• D. B only

Hint:

Two statements are of the form 'some ... some ...' or 'one individual ... some members ...', which prove nothing. Check the other two by sets.

Answer 1

The Correct Option is A

Step 1: Statement A:
Some farmers are rocket scientists, and some rocket scientists catch snakes. The snake-catching rocket scientists may not be the farmers. A fails.

Step 2: Statement B:
Poonam is a kangaroo, and some kangaroos are made of teak. Poonam may not be one of the teak ones. B fails.

Step 3: Statement C:
No bulls eat grass, and all matadors eat grass. So no matador can be a bull. 'No matadors are bulls' follows, and both segments are used. C works.

Step 4: Statement D:
Some skunks drive Cadillacs, and all skunks are polar bears. So those skunks are polar bears who drive Cadillacs. 'Some polar bears drive Cadillacs' follows, using both segments. D works.

Step 5: Match with the options:
The valid statements are C and D.

Final Answer:
The correct option is (1): C and D
