The correct answer is D. Lack of sentence variety
Explanation:
Sentence variety refers to the way different grammatical constructions and types of sentences (simple, complex and compound) are used in a text or speech to convey a message. Sentence variety is especially important as it provides a good flow to the text by creating sentences that connect to each other, avoids the repetition and helps the reader to understand the text better. In the excerpt present, which is an informal text, the writer is telling to Shelley his or her experience in Venice, mainly by describing the city and other features of the place such as the gondolas, the buildings, and the artwork. This excerpt is very detail and grammatically correct, but lacks sentence variety, each of this sentence is a simple sentence, which makes the paragraph be divided into multiple short sentences that make the reader stop after every little detail and does not lead to a good flow, instead the writer could create longer complex and compound sentences that are connected with linking words and not just periods. This will improve the flow of the text, avoid the repetition and make the text easier to understand. Thus, the most obvious fault of this paragraph is the lack of sentence variety.
