Question

Identify the simple subject of the following sentence.

Moaning myrtles sneakers light up when she runs.

Answer 1

Sneakers

Step-by-step explanation:

Moaning is describing myrtles. Therefore, we're talking about the sneakers, light up when she runs is describing what the sneaker does in motion.

Answer 2

Step-by-step explanation:

Moaning Myrtle's sneakers light up when she runs.

There are a couple of errors in the sentence. Moaning is an adjective describing a particular Myrtle (one that moans).

Myrtle is the one owning the sneakers. Normally Myrtle would be a noun. It isn't. It's a possessive noun. Myrtle is a possessive and requires an apostrophe.

sneakers is the answer.
