Identify the problem in the following sentence: My aunt came to visit we took her to the museum.
A. Fused sentence
B. Inverted word order
C. Sentence fragment
D. Comma splice

A: fused sentence.
A fused sentence is a sentence that incorrectly fuses w no punctuation.

It wouldn’t be Inverted word order because that would mean the sentence is out of order, it is in order telling us “my aunt come to visit, we took her to the museum” it wouldn’t be “we took her to the museum, my aunt came to visit”

A sentence fragment is only part of a sentence that’s only telling us one piece of information, this is a full sentence telling us everything we need to know, it’s just not punctuated correctly.

A comma splice is using a comma where one is not needed, I see no comma in this sentence, therefor this wouldn’t be correct.
