Reactions!!!!!

The following are practice for test preparation.  I have a very difficult time with reactions.  Any suggestions before the final would be appreciated.  Thanks!

For the formation of the following ester, supply the missing reactant
                                                                                       o      c
                                                                                       =      -
_______________+_______________________yields c-c-c-c-o-c-c-c
                                                                                               -
                                                                                               c
(O is double bonded to C)

     O
      =
c-c-c-c-c yields (with H2/Pt) ??
(Double bond O)

     O
      =
c-c-c-o-c-c-c yields (with H+/H2O)  ??  
(double bond O)

        O
         =
c-c-c-c-o-bezene ring yields(with NaOH/H2O)
(double bond O)

Thank you for any help!!!!!!!!!!!!!!!!!!!!!
