Question

1. which advantages result from using incineration over a landfill to dispose of municipal solid waste?

i. minimizing waste volume
ii. minimizing air pollution
iii. generating usable heat energy
iv. requiring more municipal solid waste
a. i only
b. ii only
c. i and iii
d. ii and iii
e. i, iii, and iv

Explanation:

Incineration reduces the volume of municipal solid waste (I). It can generate usable heat energy (III). However, it does not minimize air pollution (II is incorrect as incineration can produce pollutants). And it does not require more municipal solid waste (IV is incorrect).

Answer:

C. I and III
