Minimal pairs are a tool used in linguistics to discern the phonemes in a language. A minimal pair is a pair of words that differ in only one sound. They are useful for identifying salient (meaningful) differences in the phonetics (sounds) of a language. For example, consider the words "bit" and "bat" - identical except for the vowel sound: because English speakers can hear the difference and would say these are different words, we conclude there are two different phonemes - short i and short a in English. On the other hand, "grab" and "glad" differ in two ways and so they are less useful for zeroing in on the structure of the language.

What we will try to do in this exercise is to identify options that differ in just one property.

Example

Maybe the exercise would be to identify existing products or services that differ by just one thing? Or some aspect of education? Or
