Answer:
The correct answer is actually letter A) Moreover, students will benefit from having the most current information.
Step-by-step explanation:
We are looking for the sentence that uses formal language properly. The one that does so is letter A.
Informal language is more casual and spontaneous. It shows a preference for shorter, simpler words, and conveys the message in a more direct way. Formal language is employed in certain spoken situations - a lecture or an interview, for instance - and is preferable when writing essays or academic papers. It takes grammatical rules into consideration, and the tone is more impersonal.
Let's compare:
No wonder he didn't show up! (Informal)
His failing to attend comes as no surprise. (Formal)
Letter A presents a formal-language version of sentence 6. "Not to mention" becomes "moreover"; "the pluses" become "benefit"; "the latest and greatest info" becomes "the most current information". The message is the same, but the observance of grammatical rules and impersonal tone is different.
Note*: Letter B did well up until the word "info", which is a bit informal. Also, it fails to mention that it is a plus, that students will benefit from the access. Thus, it is not the best option to revise the sentence.
