Hi Experts ,

Can you please advise why not C and in OA don't we need a conjunction before comma?

Please advise an correct me.

Many thanks in advance.

The semi-colon in C should separate two independent clauses. Here is what precedes the semi-colon: Congestion pricing, the practice of charging a fee for driving into the busiest areas of a city at the busiest times. This is not an independent clause. It consists of a subject, "Congestion pricing," and a long modifier describing that subject. There's no main verb here, so this usage is incorrect.

in OA don't we need a conjunction before comma?

In the OA we have a non-restrictive modifier set off by commas. (Portion in red is a modifier.) Congestion pricing, the practice of charging a fee for driving into the busiest areas of a city at the busiest times, has more support among economists than among politicians. There's no need for a conjunction here.

The main clause is Congestion pricing has more support among economists than among politicians.

Hi David ,

Thank you so much for your reply. Can you please give me some example, where we don't need a conjunction.

Many thanks in advance.

We'd use a conjunction if we were connecting multiple elements within a given a grammatical category. If you're using a single modifier to describe a subject, there's no need for a conjunction: Dave, a GMAT tutor, is a nice guy. There's one modifier here - a GMAT tutor - so there's no need for a conjunction.

But if you were using multiple modifiers, a conjunction might be appropriate. Dave, a GMAT tutor and a doting father, is a nice guy.

Of course, that's not just true for modifiers. If you had multiple actions, you'd use a conjunction. Tom wants to go the beach and then drive to the movie theater. Or if you had multiple clauses, you'd use a conjunction. Tom wants to go to the beach, but Tim wants to play golf.

So it isn't the presence or absence of commas that dictate whether we use a conjunction, it's whether we have multiple elements in the same category that we need to connect somehow.
