Step-by-step Solution:

Solution

The goal is to find pairs of letters in the word CAMBRIDGE where the number of letters between them in the word is the same as the number of letters between them in the English alphabet. We must check this in both forward and backward directions.

Analysis:

After checking all possible combinations, two such pairs are found:

• First Pair (A-G):
  In the word CAMBRIDGE, there are 5 letters (M, B, R, I, D) between A and G. In the alphabet, there are also 5 letters (B, C, D, E, F) between A and G.
  
• Second Pair (G-I):
  In the word CAMBRIDGE, the pair is found by looking backward: CAMBRIDGE. There is 1 letter (D) between I and G. In the alphabet, there is also 1 letter (H) between G and I.
  

Conclusion:

There are exactly Two such pairs in the word.
