Question

Which of the following did Qin Shi Huangdi not standardize?

the widths of cart axles
currency
weights and measurements
the widths of canals

Answer 1

"The single width of cart axles encouraged trade as there was no delay in moving goods through the provinces. All carts would travel in the same wheel ruts and there would be no need to change to a cart with a different axle width in different provinces."

"Across the entire empire lengths, *weights and measures* were standardised. In any part of the empire people would receive the same amount of goods wherever they bought them. Also, a single *currency* and script were introduced. These actions benefited the country because trade and communications were much easier."
