Verbal Ability - Spotting Errors - Discussion

@Nishant.

An industry as defined by many dictionaries is a particular form of economic or commercial activity. There are many industries around the world: the car industry, the computer industry, the clothing industry, the list goes on and on. Those are all examples of different industries. But when you are talking about the idea or concept of such commercial activity in general, you must say industry without the article because now it's working as a mass noun.

The manufacturer is growing not the industry. The sentence is stressing on the manufacturer's growth. Not on the industry's growth.

It's option A because 'one of' or 'any of' is followed by plural words.

So here 'Industry' becomes 'industries'.

It indicates the manufacturer I think instead of fastest-growing it will be the fastest grower. Am I right?

The reason look after is correct because the marketing manager will take care of the marketing network.

I think there is no error as here look up(improve) suits the sentence not look after(take care).

"growing in the industry" should be replace by growing industry. Am I right?

"growing in the industry" means, It should be "growing industry".

I Think in 3rd sentence. It will be "in the company".

How come A correct I think it's fast growing.
