Question: Directions: 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.
(d) ‘C and D’ is the correct answer choice.
Statement A is invalid: The ‘Some F’ who are RS and the ‘Some RS’ who can catch snakes need not have any relationship between them.
CS = People who catch snakes
RS = Rocket scientists
F = Farmers
Note: ‘Many’ or ‘a few’ are both translated as ‘some’ to convert the statements in the standard form.
Statement B is invalid. Poonam need not be among the some kangaroos that are made of teak.
Statement C is valid. No matadors can be bulls because the former eat grass, while the latter do not.
EG: Creatures that eat grass
M: Matadors
B: Bulls
Statement D is valid. The some PB (shaded portion) are in effect the ‘Some skunks’ that drive Cadillacs.
