How to transform the current tab into an image and after that into text?

The problem I have is this: I have 2 kind of questions (see them below). So, here it is: there is a web where questions pop-up and the top 3 fastest persons who answer, get a score for that. I want to make a database with questions, but the OCR method I should use is a bit abstract to me. (NOTE: you can't click the text or select it. It's like an image into the browser). Should I save the whole page as an image and than parse the immage to get the text?

The method should be very fast and finish the whole task in less than 2 seconds. Maybe 1 second or 2 at most. My problem is that in the begining, I want to save the question and further, to save the answer, but for now, I have no ideea how to treat the question in order so save it.

I would like to know a method to use a C# library for OCR. The data storage will not be a problem.
