Concept:The supply curve shifts only when a non-price determinant of supply changes.
A change in the price of the good itself causes movement along the same curve, not a shift.
Explanation:Technology affects production efficiency and shifts the supply curve.
Weather influences output, especially in agriculture, and can shift supply.
Population size affects the availability of labour and the number of potential producers.
These are genuine supply-side factors.
Price is not a supply shifter because it only moves the point along the curve.
Taste is a factor that shifts demand, not supply.
Thus, the set containing technology, weather, and population is the best answer.
Answer:B. Technology, weather and population
