May need way to select image from original document while editing questions
Consider page 3 of Exam3BS110s08dem.pdf, which has a food chain above question 6a. This food chain, unfortunately, seems to have been "drawn" completely with text. The line (probably hyphens) is included in choice (c) of question 5, but then the actual text of the food chain is included after choice (b) of question 6.
The text can be deleted, but then the food chain is not included at all.
