Statement: Should high chimneys be installed in industries?

Arguments:

1. Yes. It reduces pollution at ground level.

2. No. It increases pollution in upper atmosphere

  • A.Only argument I is strong
  • B.Only argument II is strong
  • C.Either I or II is strong
  • D.Neither I nor II is strong
  • E.Both I and II are strong

Answer: A

Correct answer: Only argument I is strong

Argument I names the purpose of a tall chimney: it releases the smoke well above the ground, where people breathe. Argument II confuses matters - the same quantity of smoke is released either way, so pollution is dispersed rather than increased. Only I is strong.
