[amp_mcq option1=”but also how long” option2=”but also on how long” option3=”but also on how much long” option4=”No improvement” correct=”option1″]
The correct answer is: A. but also how long
The other options are incorrect because they do not use the correct preposition. The preposition “on” is used to indicate a location or position, while the preposition “how long” is used to indicate a period of time. In this sentence, the writer is trying to say that the results depend not only on how much you have studied, but also on how long you have read. Therefore, the correct preposition to use is “how long.”
Here is a brief explanation of each option:
- Option A: “but also how long” is the correct answer because it uses the correct preposition.
- Option B: “but also on how long” is incorrect because it uses the preposition “on,” which is used to indicate a location or position.
- Option C: “but also on how much long” is incorrect because it uses the preposition “on” and the adverb “long,” which is not a correct combination.
- Option D: “No improvement” is incorrect because the sentence is already correct.
