Thanks Andy030,
after reread page 57 again and again finaly it make sense to me that the topic in page 57 is one of the main(important) part of PRing. Forming questions of the material we've read can stimulate our brain to find the answers and not necessarily we can get the answrs at that very moment but our brain will continuely finding the answer even when we did not think about the questions anymore until.....the AHA !!! will pop up from our mind.
Since my only source available is the PR book and this forum, do you think I can do it?
