Difference question (please the attached files)

This work is about an exam preparation. My tutor has given me an 5 exam questions which would be very similar to my coming exam. So I need you to find the answer for those question (see Exam question file), I also send you an exam guide lists file which the tutor want me to follow that guide for all question (what the tutor expects to see for each question), so you should follow it carefully! each question is expected to be answer about 400 words. No need for the reference for this work. Please also use simple english level as my english is quite bad (It will be easy for me to remember it :))

Ive also uploaded all of the ppt files that the tutor taught me in the class. Plz use it as a guildline. Each ppt file is for each question.

Thanks
