…which have led to the ______ of gases and aerosols.
- (a)assimilation
- (b)absolution
- (c)collection
- (d)accumulation
Correct — D, accumulation. Human activities release gases and aerosols faster than natural processes remove them, so they build up over time, and 'accumulation' is the noun for exactly this gradual gathering or build-up. 'Collection' suggests things deliberately gathered together, 'assimilation' means absorbing or blending in, and 'absolution' means being formally forgiven — none matches a slow atmospheric build-up.
- (a)assimilation — Means absorbing or blending something in, not the gradual gathering of substances the passage describes.
- (b)absolution — Means a formal forgiveness of sins or guilt, unrelated to gases building up in the air.
- (c)collection — Implies items deliberately gathered together, not the slow, unintended atmospheric build-up meant here.
A cloze item testing the noun that best names a gradual build-up of substances in the atmosphere.
