from previous-

-the  auditorium was  house  full by  the  time  she  reached  there,   as  if  the  whole  university  had  managed  to  squeeze  in that  moment  under  one  roof , she  was  being  ushered  and  a  few  seats  were  vacant  and  became  visible  , they  quickly  occupied  the  first  two,
-they  were  asked  to  in a  authoritative  voice  instructed  to  go  to  the  last   seats  in the  end  so  to  make  it  easier  for  the  late comers, the  voice  was either  of  their  class  fellow  self  declared  monitor or  belonged  to  a  senior  but  without  any  further  argument  they   moved   further  to  leave  their  seats   vacant  for  the  following  students,
