Question and options

Direction: The question has a main statement followed by four statements labelled 1, 2, 3, 4. Choose the ordered pair in which the first statement logically implies the second, given the main statement.

Main statement: Every 12 hours the clock strikes 12.
1. 6 hours have elapsed since the last time the clock struck 12
2. The clock will strike 6 times anytime now
3. 6 hours hence, the clock will strike 12
4. The clock strikes 6 every 6 hours
  1. 3, 2
  2. 3, 1
  3. 4, 2
  4. 1, 2

Answer and explanation

Correct answer: B - 3, 1
The clock strikes 12 every 12 hours. If it will strike 12 six hours hence (3), then 6 hours have elapsed since it last struck 12 (1): the pair 3, 1. The main statement says nothing about the clock striking 6, so pairs ending in statement 2 do not follow.
