Answer:
are added; will decline eventually
Step-by-step explanation:
the point of diminishing returns sets in when the optimum capacity has been attained. at this level, increasing production by any extra unit would only bring about little or Fall in output.
if we hold the other factors of production constant/fixed while increasing one input, we will get toa stage where more additions of this input by one unit would only bring about decrease in output or cause output to fall.
therefore in summary this law States that as more increments are added, marginal benefit from increments declines eventually.
