Each answer below contains an error. select the example of the error known as a run-on sentence. a. he went to the library. because he wanted a book. b. he went to the library he wanted a book. c. went to the library. d. he went to the library. after he wanted a book.

A. The error is the use of 'because' in a separate sentence. The conjunction 'because' links two clauses within the same sentence. The correct sentence would be:

He went to the library because he wanted a book.

B. The error is the lack of a conjunction linking the two clauses, this is, a conjunction like 'because' is missing.

He went to the library because he wanted a book.

C, Went to the library is a case of run-on sentence because it has no subject.

The structure of this run-on sentence is: <*Subject missing> + <Main Verb> + <Preposition> + <Determiner> + <Noun/Prepositional Object>

D. The clause he went to the library expresses a consequence and he wanted a book expresses a cause, therefore the use of 'after,' expressing time, as a linking word is incorrect. Only conjunctions like 'because' or 'so' can  be used in this case.

He went to the library because he wanted a book.

He wanted a book, so he went to the library.
