Question 7
Choose the option that best describes the meaning of the underlined word in the given sentence.
Ehrlich's argument that expanding human populations cannot be sustained on an Earth with finite carrying capacity is irrefutable and, indeed, almost tautological.
Solution
Option A: Correct.
Understanding the meaning of the word and then the sentence is the key to the question.
Even if one of them is correctly understood, one may arrive to the right answer.
Irrefutable uses "ir" suffix which means "not", so irrefutable means something that can not be refuted.
So the sentence now means Ehlrich's argument can not be refuted or proven incorrect.
So option A, Indisputable is closest in the meaning.
