Font resizing in the question header ad text

[brianagina]

Resizing the question header in red and the question text before the tables to match with the initial font size in previous pages. For example the question header "Do this in groups" should be of the same font size as page 15 of the EPUB. And the question text "Which is the odd one out?" should be of the same font size as the caption's text font size. This is applicable to the drag and drop question as well.
