    Question

    In the question below, a sentence is given with two blanks in it. Six choices of words have been given in two columns. The word for the first blank should be from the first column and for the second blank it should be from the second column. Choose the correct combination from the options which can fit in the blanks and make the sentence meaningful.

    A CE Correct Answer Incorrect Answer
    B BD Correct Answer Incorrect Answer
    C AF Correct Answer Incorrect Answer
    D CD Correct Answer Incorrect Answer
    E BE Correct Answer Incorrect Answer

    Solution

    The sentence tells us how the need to remember and manage relationships might have affected the brains of certain animals. 'Network' is the only suitable word from the first column for the first blank. 'Evolution' fits the second blank, as it tells us the effect of this effort on the brains of those animals. The other two words of both the columns do not make sense in their respective blanks. CD is the correct pair. Option D is the right answer.
