The correct answer is: E. No error
The sentence is grammatically correct. The word “which” is used to refer to a specific person or thing, and in this case, it is referring to the driver who had met with the accident. The word “had met” is the past participle of the verb “meet,” and it is used in this sentence to indicate that the driver had already been in an accident. The word “with” is a preposition, and it is used in this sentence to indicate that the driver had been in an accident. The word “the” is a definite article, and it is used in this sentence to indicate that the driver was a specific driver. The word “accident” is a noun, and it is used in this sentence to indicate that the driver had been in a car accident. The word “would have died” is the past conditional of the verb “die,” and it is used in this sentence to indicate that the driver would have died if the bystander had not been familiar with first-aid techniques.
Here is a breakdown of each option:
- Option A: “If the by-stander had not been” is grammatically correct. The word “if” is used to introduce a condition, and the word “had not been” is the past participle of the verb “be,” and it is used in this sentence to indicate that the bystander was not familiar with first-aid techniques.
- Option B: “familiar with first-aid techniques” is grammatically correct. The word “familiar” is an adjective, and it is used in this sentence to describe the bystander. The word “with” is a preposition, and it is used in this sentence to indicate that the bystander was familiar with first-aid techniques.
- Option C: “the driver which had met” is grammatically incorrect. The word “which” is used to refer to a specific person or thing, and in this case, it is referring to the driver who had met with the accident. However, the word “which” cannot be used to refer to a person or thing that has already been mentioned. In this case, the word “that” should be used instead of “which.”
- Option D: “with the accident would have died” is grammatically correct. The word “with” is a preposition, and it is used in this sentence to indicate that the driver had been in an accident. The word “the” is a definite article, and it is used in this sentence to indicate that the driver was a specific driver. The word “accident” is a noun, and it is used in this sentence to indicate that the driver had been in a car accident. The word “would have died” is the past conditional of the verb “die,” and it is used in this sentence to indicate that the driver would have died if the bystander had not been familiar with first-aid techniques.
