Text B, Paragraph 2
A surge in global demand for eco-friendly footwear has led to significant price increases in Italy's shoe market. One local shoe manufacturer quickly adjusted its output to produce more footwear. Analysts predict that this flexibility will allow the company to capture market share more rapidly than competitors with more rigid production methods.

Using a PES diagram, explain how flexibility in production might impact the price elasticity of supply for shoes in Italy.
