Answer:
8. run-on
9. fragment
10. run-on
11. lack of parallel construction
12. run-on
13. fragment
14. dangling participle
15. lack of parallel construction
Step-by-step explanation:
When independent clauses are joined incorrectly, we have what is called a run-on sentence. There are two types of run-on sentences. A fused sentence is the type that happens when we join the clauses without any sort of punctuation. A comma splice is the type that happens when we join them only with a comma, but no conjunction is used.
A fragment is a group of words that looks like a sentence but lacks something essential to make sense, such as the subject or the verb.
A dangling participle is a modifier that refers to something that is not mentioned in the same sentence and, for that reason, seems to be referring to something else. It causes ambiguity.
Finally, parallelism consists in the repetition of a certain grammatical structure inside a sentence. The purpose of such repetition is to avoid confusion, making the speech clear, interesting, and easy to understand. For instance, if you are listing your hobbies and you use -ing in the first one (drawing), you should use -ing for the others as well.
