Help me correct these three sentences? Thank you!

If a professor is conducting a market research of a cola company, let's say, Coca-Cola, on how do their customers feel about the taste of its new product, the new Coca-Cola. To know the answer, the professor has to ask the customers directly. His/her students can help him/her to design a questionnaire, and in this process, students can better understand the principles of designing a questionnaire.

See above for my suggestions.

Thank you. But why I can't add "a" before "market research"?

Because we don't do "a market research", we simply do/undertake "market research".
