GMATNinjaWhen it comes to parallelism with prepositions, when MUST I use the preposition and when CAN I assume it is implicitly there? For example, which of the following sentences are correct?
“He enjoyed talking to his friends
at the gym and
at the store.”
“He enjoyed talking to his friends
at the gym and the store.”
Also, how can I determine whether the content that is being paralleled is the prepositional phrase or the nouns themselves? Is there a precedence (e.g., if there is a prepositional phrase parallelism opportunity, you must use the preposition parallel structure even if you can parallel just the nouns)? For example, is there a precedence of one of the sentence structures below over the other?

Posted from my mobile device Like a lot of SC issues, this one depends on context. Consider 3 different scenarios.
Scenario 1: "Tim has lived in France and Spain." vs "Tim has lived in France and in Spain."
The two sentences are on equal footing. They mean exactly the same thing and so the GMAT can't ask to choose between them.
Scenario 2: "Tim has lived both in France and Spain" vs "Tim has lived both in France and in Spain."
Now, because we get that special parallelism trigger, "both," the two elements following the trigger must be identical. Therefore, "Tim has lived both
in France and
in Spain is correct," while the first sentence is incorrect.
Scenario 3: "A combination of vanilla and chocolate makes for a delicious sundae." vs "A combination of vanilla and of chocolate makes for a delicious sundae."
This one comes down to meaning. The construction in the second sentence, "a combination of vanilla and of chocolate" doesn't make sense, because it sounds as though there are two combinations: one combination of vanilla and a second combination of chocolate. But a combination, by definition, contains at least two elements. A combination of vanilla alone is incoherent, since the vanilla hasn't been combined with anything, so you don't have a sundae at all! In this case, we'd want one combination, consisting of vanilla and chocolate.
The takeaway: first, determine whether you have a special parallel trigger, such as "both." If you do, the components must both have the preposition if the first element does. Otherwise, ask yourself if the presence or absence of the preposition changes the meaning. If it doesn't, the two are on equal footing, and it's not a decision point. If the preposition
does change the meaning, ask yourself which construction is more logical.
I hope that helps!
Another follow up question on parallelism: Why does the sentence sometimes end in an object form of the pronoun and sometimes the subject form? For example:
“She now had a number of friends much smarter than she.” vs.
“Compared to the Jones, Peter was better suited to the lifestyle than they were.” vs.
For each set of sentences, is it that one sentence is better than the other or is one of the two actually wrong?
