Final answer:
The data entry containing a misplaced comma is B) The culture, did not grow any bacteria because the comma separates the subject from its verb unnecessarily. Commas should be used to enhance clarity in sentences, not to disrupt them.
Step-by-step explanation:
The data entry with a misplaced comma is option B) The culture, did not grow any bacteria. The comma after 'culture' is not needed and improperly separates the subject from its verb. Commas should be used to separate clauses, before conjunctions in compound sentences, after introductory elements, in lists, and to set off non-essential information. In this case, the sentence should read: The culture did not grow any bacteria, without a comma.
When reviewing entries for comma usage, it is crucial to identify if the sentence structure requires a comma for clarity or if it disrupts the flow of the sentence. For example, in the provided sentences, the following corrections would apply:
- 1. I finally found my keys, and I got to work just in time. (Add comma before the conjunction.)
- 2. Mrs. Contreras threw out her old coffee table and cleaned the carpet. (Omit comma as the sentence contains two verbs but is not a compound sentence.)
- 3. Taking the elevator to the roof, we hoped we could see the skyline and the bay. (Place a comma after introductory phrase and omit the comma before 'and' because it's not a compound sentence.)
- 4. Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy. (Place a comma after the introductory clause and before 'and' in the list if following the Oxford comma rule.)
- 5. I let my neighbor borrow my phone because she said hers was tapped by the police. (No comma needed as the reason is directly related to the action.)
Understanding the rules of comma placement is an essential part of writing clear and coherent sentences. Omitting or incorrectly placing a comma can alter the meaning of a sentence or create confusion for the reader.
