The passage directly states: "By 1873 Britain was exporting iron and steel worth about £77 million, double the value of its cotton export." This is a straightforward fact-based MCQ — memorise the figure along with the context (double cotton exports) as examiners sometimes ask it as a one-liner or short answer too.
