(b) By taking one example of a local plant and animal, how would you help these parents to overcome such inhibitions about reproduction and sexuality?

Similar to the social science exam, the questions were generic while them being taken from the syllabus. The students had provided their answers in a generic manner instead of being specific as they were not taken from any particular chapter.
