Which one of the following letters is as far after I as R is after G in the alphabet?

To determine which letter is as far after I as R is after G, we first need to calculate the distance between G and R in the alphabet.

The letter G is the 7th letter, and R is the 18th letter. To find the distance, we subtract the position of G from that of R:

18 (R) - 7 (G) = 11.

Now we apply this same distance to I. The letter I is the 9th letter in the alphabet. To find the letter that is 11 letters after I, we add 11 to the position of I:

9 (I) + 11 = 20.

The 20th letter of the alphabet is T.

Therefore, the correct answer that matches the distance calculation from I is T, not U. U is the 21st letter of the alphabet, which is only 1 place after T.
