Consider these GP essay questions :
Are traditional gender roles still relevant ?
Is the television obsolete ?
Do we still need libraries ?
Has travel become increasingly unimportant ?
The topics (in red) can change, but the basic approach to the question need not.
Step 1 : What are the functions of the topic ? (tv, libraries, gender roles, travel etc.) Identifying the functions will help you decide which functions have been affected by change, and which ones have not.
Step 2 : What are the factors that stimulate change ? (technology ? laws and other government initiatives ? exposure to new or foreign things and ideas ? education ? affluence ? etc) What kind of changes take place as a result ? Have the original functions been affected ?
Step 3 : Which parties are affected by the change ? (consumers ? businesses ? the government ? ) How are they affected ? Which parties/groups are not so affected by the change, hence sustaining the relevance/importance of the topic in question ?
These steps help you get a fuller answer, and you can then decide how you want to sensibly arrange these ideas.
