C for me.

Here is my logic.

First there is a SVA issue. Companies in the pollution control industry....have recently experienced.. So it needs to be have instead of has - this eliminates A, D, and E.

We read choice b and see that when prospering is incorrect - should be was prospering to be in SVA with the sentence. So that leaves us with only C.

Hope that helps.

The first logic is correct ie the options will end with 'have'.
But for SVA shouldnt it be 'many companies...were prospering...'? IMO the option doesnt match up.
Am I right?
Also, where is this question from?

This is where i also got confused. Seems like the 'were prospering' modifier is for the industry. It wasn't intuitive or explicit.

I got these questions from the Jamboree question bank

Which makes the remainder of "until a few years ago...." refer to the industry not the companies. So it should be the industry was prospering not the industry were prospering.

Make sense?

IMO, this is not a valid example . It is just not about SVA alone but there is also an element of comparison in it. In the original, we are comparing performance of the industry until few year’s ago with the performance of the companies recently. This shift of object is illogical. Per se, logically speaking, the companies, the subject of the clause, do two functions; first, they did well earlier and then have not not so well recently. If we mean to describe the industry’s profits, thenwe can straight away start with the industry, dropping the reference to the company’s altogether.

IMO, this is a faulty topic and no choice is tenable

plural subj needs plural verb

the modifier is more clear here

In above the c answers the question correctly. SVA issue leaves us with just B and C. Out of the two C is correct since the was refers to singular Pollution Control industry and have correctly refers back to Many Companies.

the 'which' takes the immediate preceeding noun i.e. 'control industry' -> hence 'was' is correct
