Answer:
The correct answer is Subsidizing research and development into new weaving technologies.
Step-by-step explanation:
Human capital and investment in Research and Development are considered the two main drivers of productivity accross nations. The weaving industry is labor-intensive, but does not require highly qualified workforce, thus, an economic policy focused on education might not have a direct impact on productivity. Investing on R&D might be a better policy since it might lead to improving production techniques and increased productivity in the long term.
