How to approach it

Predict from the governing principle before looking for a matching option. Then reject alternatives by checking direction, units, limiting behaviour or the physical meaning of each statement.

  1. 1

    The correct choice is B: 0.60

  2. 2

    A is the fraction above the surface. D inverts the ratio and should be rejected on sight — a fraction of a volume cannot exceed 1.
