Given below are two statements :
Statement I : Municipal solid waste includes Garbage and Rubbish.
Statement II : Garbage consists of both combustible and non combustible materials.
In the light of the above statements, choose the most appropriate answer from the options given below :
Statement I is true but Statement II is false.
This question tests the correct classification of municipal solid waste (MSW).
Statement I says municipal solid waste includes garbage and rubbish. This is true. MSW is broadly divided into garbage (putrescible, decomposable food and kitchen waste), rubbish (non-putrescible waste), ashes, and other categories. So garbage and rubbish are indeed components of MSW.
Statement II says garbage consists of both combustible and non-combustible materials. This is false. It is rubbish, not garbage, that is made up of both combustible materials (paper, cardboard, wood, plastic) and non-combustible materials (glass, metal, crockery). Garbage specifically refers to the wet, decomposable, putrescible organic waste from food preparation and handling. Mixing up the definitions of garbage and rubbish is the trap here.
Therefore Statement I is correct but Statement II is incorrect.
Why the other options are wrong:
Saying both statements are true wrongly accepts the false definition of garbage.
Saying both are false wrongly rejects the correct statement about MSW composition.
Saying only the first is false and the second true reverses the actual truth values.
Takeaway: Garbage = decomposable food waste; rubbish = the mix of combustible and non-combustible dry waste.
Correct answer: Statement I is correct but Statement II is incorrect.
