she decided to leave her job and travelling the world. *\n\nparallel\nnot parallel

Brief Explanations:

Parallelism in grammar requires that items in a series or connected by a conjunction (like "and") follow the same grammatical form. In the sentence "She decided to leave her job and travelling the world," the first item is an infinitive ("to leave"), while the second item is a gerund ("travelling"). To be parallel, both should be infinitives ("to leave... and [to] travel") or both should be gerunds. Because the forms are mismatched, the sentence lacks parallel structure.

Answer:

Not parallel
