The correct answer is: D. No error
The sentence “The test will not need more than one and half hour to finish” is grammatically correct. The phrase “one and half hour” is a compound adjective that modifies the noun “test.” The phrase “to finish” is a prepositional phrase that modifies the verb “need.” The sentence is clear and concise, and it conveys the intended meaning accurately.
The other options are incorrect because they contain grammatical errors. Option A is incorrect because the verb “need” does not require a direct object. Option B is incorrect because
the phrase “more than one and half hour” is not a grammatically correct way to express the amount of time. Option C is incorrect because the prepositional phrase “to finish” is not necessary in this sentence.
