• 1. D
  ( why because in the case of S was happened when R should Happened.Similarly R was happened by Q,And finally Q was happened by p).

• 1. (c) because R happens means S happens, so S was happened means R was happened. If R will be happen
  then after S will happen. So without R S will not happen.
  
  2.(b) because S was not happened means R was not happened, R was not happened means Q was not happened and Q was not happened means P was not happened.
