Answer 2

Answer:

There are three pairs which are S & T, G & I and S & U.

Explanation:

Looking at the letters of the word DISTINGUISH we see that for:

S T: going either in the forward or backward direction, there is no letter between them as it is in the English alphabet.

G I: In the alphabet, it is G H I, meaning there is only one letter between G I. In the word distinguish, we get G U I meaning either going back or forward, the pair is separated by one letter.

S U: The alphabet is S T U while in the current scenario we have U I S. Going forward or backwards in the alphabet, S U are separated by one letter.
