Multiple choice

Directions: In the following question, an argument is followed by two assumptions. Which of the assumptions is/are implicit in the argument?

Argument: In mathematics, the principles are palpable, but removed from ordinary use so that for want of habit, it is difficult to turn one's mind in that direction. But if one turns it thither ever so little, one sees the principles fully. Assumptions: (A) One must have a quite inaccurate mind to reason wrongly from principles of mathematics. (B) It is almost impossible that principles of mathematics should escape notice.

  1. Assumption (A) alone is implicit.

  2. Assumption (B) alone is implicit.

  3. Both (A) and (B) are implicit.

  4. Neither (A) nor (B) is implicit.

  5. Either (A) or (B) is implicit.

A Correct answer
Explanation

Only assumption (A) is implicit. If one turns one’s mind to the principles, one sees them fully, so that one will not reason wrongly from them. Assumption (B) is not implicit as ‘it is difficult to turn one’s mind in that direction’.
