Paracompletion Question 1 - CAT 2023

The sentence fits best in Option 3 because it comes right after the paragraph introduces the surprising genetic connection between Native Americans and Japanese people. At this point, the reader already knows about the discovery, so the sentence can naturally explain what this finding means from an archaeological point of view.

The earlier positions don’t work because the genetic connection has not been properly introduced yet. Putting the sentence there would make the explanation feel out of order.

The second position is especially unsuitable because there is no earlier reference to a discovery that the sentence could explain.

The last position would also disturb the flow. The similarities are already mentioned before that point, and the following sentence begins with “This suggests,” which clearly refers to those similarities. Adding the given sentence there would break that connection.

Therefore, Option 3 is the correct choice.
