Which of the following sentences is written correctly?
A When properly designed, an automobile can achieve great fuel efficiency.
B. When properly designed an automobile can achieve great fuel efficiency.
C. When properly designed, great fuel efficiency can be achieved by an automobile.
D. When properly designed great fuel efficiency can be achieved by an automobile
I think A
yeah.
Option A is correction
Both A and C are punctuated correctly.
Correct! Sentence A is written correctly. Here's why:
In this sentence, the use of a comma after "designed" correctly separates the dependent clause ("When properly designed") from the main clause ("an automobile can achieve great fuel efficiency"). The comma helps to clarify the meaning and structure of the sentence. Without the comma, the sentence would be grammatically incorrect.
On the other hand, sentences B, C, and D are written incorrectly. Sentence B lacks a comma after "designed," which creates a run-on sentence. In sentences C and D, the placement of the subject ("great fuel efficiency") before the verb ("can be achieved") is not grammatically correct. The subject should come after the verb in this construction.
Therefore, your choice of sentence A is correct.
