Question

Choose the best option to complete the sentence.
It's been reported that human beings' lives _____ prolonged by a new wonder drug.

• A. has been
• B. will have been
• C. are being
• D. will be

Answer 1

Answer: (C)

are being

Option C is correct as the sentence is in the present perfect tense and it states that the process of prolonging human lives is still happening. Hence the option, are being, is the correct answer.

Option A is incorrect as the plural noun, lives, requires to be followed by 'have' and not 'has'.

Option B is in the future perfect continuous tense and since the sentence is in the present perfect tense, option B is incorrect.

Option D is incorrect as it is in the simple past tense and doesn't match with the general tense of the sentence.
