Answers
Answer:
Which is the underlined portion ?
Answer:
1= You don't, because it's false. If all black dots happen to be on the line and white dots on the line (and the rest of the plane is neither white nor black), there is no such pair.
2= At night , the air is denser due to humidity (obviously nights are cooler). sound requires medium to travel and so DENSER the medium, FASTER the sound travels. Humid air is denser than warmer air as in day.
3= D is the right option
You first have to realize that 26 minutes is the same thing as "under a than half hour." Once you see this, you know that the question is testing editing out repetition.
The original (answer A) doesn’t work, since it’s repeating the route length already described in the beginning of the sentence. Answer C has the same problem – it’s repeating the route time exactly as already expressed. Answer B takes one type of redundancy and replaces it with another, since it’s just a variant of the words “to complete the route” already in the sentence.
So, the only answer that fixes all the redundancies is D.
