From the common observation, one could easily state that topics like sexuality and reproduction are rarely discussed between parents and their adolescent children as the former feels embarrassed. This has resulted in children losing their way sometimes.

(a) Explain the reasons that you feel are behind such embarrassment amongst some parents to freely discuss such issues with their growing children.

(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. Thus the questions were testing the general approach of students of their understanding of basic biology topics.
