To give the sentence a parallel structure, we need to ensure that all the items listed are in the same form. In this case, we are looking for a verb form that matches the structure of the other activities mentioned (shovel snow, mow the lawn).
The correct phrase to maintain parallel structure in the sentence is "to rake." This maintains consistency with the structure of the other activities mentioned and ensures that the sentence is grammatically correct and properly structured.
Therefore, the completed sentence should read: Paul doesn't like to shovel snow, to mow the lawn, or to rake leaves.
