Given the task definition, example input & output, solve the new input case.
In this task, you are given two phrases: Head and Tail, separated with <sep>. The Head and the Tail events are short phrases possibly involving participants. The names of specific people have been replaced by generic words (e.g., PersonX, PersonY, PersonZ). PersonX is always the subject of the event. You have to determine whether the Head happens before the Tail or not. Classify your answers into "Yes" and "No". The phrase may also contain "___", a placeholder that can be an object, a person, and/or an action.
Example: Head: PersonX swims at the local pool<sep>Tail: PersonX learns a new way of swimming
Output: Yes
This is a good example. The Head happens before the Tail.

New input case for you: Head: PersonX achieves PersonX's potential<sep>Tail: to learn their potential
