I have to underline the word or phrase or clause that is not parallel sentence and then rewrite it
The dog had to choose between jumping over the fence or he could have dug a hole underneath it.
Is this correct: I would underline between and to rewrite the sentence as follow
The dog had to choice either jumping over the fence or digging a hole underneath it.
So for the next sentence:
She disliked going to the beach, hiking in the woods, and she didn't care for picnics either.
So I would underline: and she didn't care for picnics either.
So my new sentence would be:
She disliked hiking in the woods also she did not care for picnics and going to the beach.
You need to underline or he could have dug a hole underneath it.
Your correction is correct (except for choice rather than choose).
You don't need "also."
A better sentence:
She disliked hiking in the woods, picnicking, and going to the beach.
To determine if a sentence is parallel, we need to look for elements that should be in the same grammatical form. In this case, we are comparing two actions that the dog could have done: "jumping over the fence" and "digging a hole underneath it."
In the original sentence, the phrase "between jumping over the fence or he could have dug a hole underneath it" is not parallel. This is because the verb forms are different: "jumping" is a gerund (a verb form ending in -ing, used as a noun), while "dug" is a past tense verb.
To correct this, let's rewrite the sentence to make it parallel:
The dog had to choose either to jump over the fence or to dig a hole underneath it.
In this revised sentence, both options are presented using the same grammatical form, using infinitive verb phrases starting with "to."
