a decrease in productivity would be represented by a change from\na. a to b\nb. b to a\nc. s₁ to s₂\nd. s₂ to s₁

Answer

Brief Explanations:

A decrease in productivity means that for the same cost, firms can produce less. This shifts the supply curve to the left. The original supply curve is $S_1$ and a left - ward shift gives $S_2$. So a decrease in productivity is represented by a change from $S_1$ to $S_2$.

Answer:

C. $S_1$ to $S_2$
