The real place should theoretically have space for 87 passengers if it is an exact model and doesn't have modifications in the seat numbers.

The correct answer is:
Work is negative, the environment did work on the object, and the energy of the system decreases.
In fact, the work-energy theorem states that the work done by the system is equal to its variation of kinetic energy:
In this problem, the variation of kinetic energy 
is negative (because the final velocity is less than the initial velocity), so the work is negative, and this means that the environment did work on the object, and its energy decreased.
Change in state(from liquid to solid) and change in colour I believe.
