Question

unit test
choose the option that correctly pluralizes the missing word in this sentence.
most of my favorite music was made in the ______.
choose 1 answer.
a 90s
b 90s
c 90s

Explanation:

To pluralize a decade like the 1990s, we abbreviate it as '90s: the apostrophe comes before the numbers to stand in for the omitted "19", and we add an "s" to indicate the plural decade without an extra apostrophe after the "s" (which would show possession, not plurality).

Answer:

C. '90s
