These questions are taken from I.M.Copi's 'symbolic logic' ( edition -5, sec. 3.8, pg- 61 )philo q.jpg
File is being attached.

Your difficulty appears to be not only with Symbolic Logic but also with reading English. It is clearly stated that this forum is not intended to do your work for you but to help you. Tell us what you do understand about this problem (you might begin with telling us what your understanding of the "strong method of conditional proof" is) and you have been able to do on it.
