Which of the following options DO NOT fit in the 3 R's of waste management?

  1. A.Refuse
  2. B.Recycle
  3. C.Reduce
  4. D.Reuse

Correct answer

A. Refuse

Explanation

The correct answer is A, Refuse. The 3 R's of waste management are Reduce, Reuse and Recycle; Refuse is not one of them. Reduce means creating less waste in the first place, such as buying fewer packaged goods and switching off lights to save power. Reuse means using a thing again, like refilling a bottle or turning old clothes into bags. Recycle means sending waste such as paper, glass, metal and plastic to be made into new products. NCERT gives the three in this order, and the order matters: reducing is the best option and recycling the last resort because it still uses energy. Some newer lists add Refuse and Repurpose to make 5 R's, but the paper asks about the 3 R's. B is wrong because recycling is one of the three. C is wrong because reducing is the first R. D is wrong because reuse is the second R. Exam tip: 3 R's = Reduce, Reuse, Recycle, in that order of preference.
