Answer:
The British argued that opium was only a fraction of the volume of trade delivered to China.
Explanation:
Opium was the only trade good that the British could sell in China at a profit. The British had, for centuries, been purchasing Chinese tea with silver, but the Chinese could not be enticed by any manufactured British goods. Opium, however, was another story. It was much stronger and potent than the opium China was able to produce.
