Q&A Module?
 

I am looking for a modification to show Questions/Answers in product page.

It could be a complex solution or just a simple one. For example you get a question by email or from product page then you publish the question and answer in a special tab called Q&A.

I found over time that this modification helps a lot, much better than a testimonial or customer review.
