The correct answer is option 1) i.e. DCBA.

  • D is the first sentence because it introduces the subject of the passage 'acid rain' and explains it.
  • Both B and C can be placed in the second position, but since BA would form a pair, C would follow D.
  • B talks of 'emissions of sulfur dioxide and nitrogen oxide' and A talks of governments' efforts to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere. Therefore, A must follow B.
