Question

Which of the following measures in the 4R principle means to use resources less and only when necessary?

• A. Reduce
• B. Reuse
• C. Recover
• D. Recycle

Answer 1

The correct option is A Reduce

The 4R principle to save environment from pollution are:
$\bullet$ Reduce - Minimal use of resources to reduce the amount of waste produced from it
$\bullet$ Reuse - Use the resources again instead of throwing them away after single use
$\bullet$ Recycle - Most materials can be recycled into another form instead of dumping them after use
$\bullet$ Recover - Reclaiming the materials helps to process them and make use of them elsewhere

So, reduce is one of measures in 4R principle which indicated to use the resources less.
