Question

Which sentence uses the correct form of the verb?

A
Bright flowers are a sign of spring.
B
That bird nest are a sign of spring.
C
The big, blue sky are a sign of spring.
D
A white butterfly are a sign of spring.

Answer 1

'A' is the only sentence that displays correct grammar. "Are" should be used to refer to the plural form (in this case, bright flowers) of a noun. In the incorrect choices, "are" is referring to singular nouns, which is not grammatically correct.
