I want to know the answer to the following question:
In the 1840s, what country could no longer adequately supply the British cotton mills?
All the background I'm provided with is that "By the 1840s, India was no longer capable of supplying the vast quantities of cotton fibers needed by mechanized British factories, while shipping bulky, low-price cotton from India to Britain was time-consuming and expensive.". Is that enough to answer the question?
Answer: yes
