Thanks
AjiteshArunSo these two parts are instead in a parallelism right? I thought when we see a "comma + conjunction" it was a sign that an independent clause was coming, and therfore there should be a noun or pronoun as the main subject of this new independent sentence. I'll be very grateful If you have any thoughts or examples to understand better this concept that seems that I need to strengthen.

Hi Crismore,
Those are some really good questions. Let's start with what's happening behind the scenes (point 1):
1. Sentences (1a) and (1b) are the same.
1a. {sub1}
{verb1} and {verb2}.
is the same as
1b. {sub1} {verb1} and {sub1} {verb2}.
All that's happening here is that content that is common to both elements joined by the
and is being removed ({sub1} is common to both). Basically, (
1a) is a reduced form of (
1b). Although in some cases we may prefer the longer version, this is generally a good thing, as it makes the sentence shorter and simpler.
2. To answer your first question, yes, you can absolutely look a this as a list of two verbs.
3. As for your second question, I know where you're coming from on this, as that "rule" has gained a lot of traction on GMAT Club. However, that "rule" really isn't all that reliable. A "
, and" between two elements doesn't
necessarily mean that those two elements must be independent clauses. Go through
this official question, and then take a look at the correct option:
A newly developed jumbo rocket will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and at a lower cost.
The problem with punctuation is that there are very few absolutes, very few rules that we can apply with confidence. This is why I generally advise my students not to prioritise calls based on punctuation.
