Take the following as truth: Governor Frederick Weld (1880 1887) extended the residency system to Negeri Sembila n and the more recalcitrant Pahang, where the Sultan Wan Ahmad was forced to open the Kuantan tin mines to British prospectors.
Then the following statement: "Sultan Wan Ahmad was required to allow British prospectors into the Kuantan tin mines." is true, false, or inconclusive?
