To answer the question we can look at the
definitions of both "efficiency". and equity", and decide which
action falls under what category:
Efficiency is the quality to successfully finish a job
without wasting any time or resources, by this definition when Eric does not
care about how the pieces are distributed, he is showing efficiency, not
wasting time or energy to distribute, but finishing the distribution.
Equity means the ability to be partial or fair with all, when Eric cares about how the pieces are
distributed, he is showing equity.
