Final answer:
The answer identifies types of errors in sentences, such as parallel structure, explanation structure, and dangling construction, and provides corrections. It also addresses comma placement and subject-verb agreement to improve sentence clarity and coherence.
Step-by-step explanation:
Identification and Correction of Sentence Errors
Here, we'll identify the type of error in several sentences and then suggest corrections to sentence structures and verb usage:
Parallel structure error in sentence 1 should be revised to 'after school we planned to do homework and to go swimming'.
Sentence 2 is correct (C) with no error as it already maintains a parallel structure.
Dangling construction error in sentence 3 can be corrected by specifying the subject, 'Players must do many warm-up exercises to prepare for the game'.
Explanation structure error in sentence 4 should be 'My reluctance to join your group arises from not knowing your activities'.
Each sentence either contains an error pertaining to parallel structure, explanation structure, a dangling construction, or there could be no error at all (C). It's important to recognize these issues to improve clarity and coherence in writing.
Comma Usage and Verb Correction
For review questions focusing on comma usage, we insert or omit commas where necessary:
Sentence 1 needs a comma before 'and' - 'I finally found my keys, and I got to work just in time.'
In Sentence 2, the comma after 'table' is correct, but not needed after 'and' - 'Mrs. Contreras threw out her old coffee table and cleaned the carpet.'.
Correct verb usage is pertinent for maintaining subject-verb agreement and ensuring clarity in sentences:
The correct form of the verb in 'Mathematics is the fundamental language of physics' (sentence 3).
