Despite the opium outlaw, the British continued to bring the drug into China. This resulted in the Opium Wars which lasted from 1839-1842. The possibility of war was threatened by Lin (leader of China) during the early 1830's when he wrote a letter to Queen Victoria. However, Britain did not see this as a threat and ended up easily defeating the Chinese due to their strong naval forces. The Treaty of Nanjing ends the Opium Wars and results in China losing Hong Kong.
The reason why it takes a long time to ratify the Articles of Confederation is that U.S. just declared independent from Britain, in other words, they just passed the Declaration of Independence, and in order to keep a country on track, they need some sorts of form of government, and they don't want to repeating the history, or have another tyrant, or a king, to rule over them again, which is a part of reason why they declared independent (the actual reasons is the king taxes us for no reason and we can't participate in the government), so they need all of the 13 states to approve, or sign, the Articles of Confederation, majority of them signed it, some of them having issues about the rights in the Articles of Confederation, so someone, I forgot his name, promised to includes all of the rights into the Articles of Confederation, which they can't do it instantly, which later known as the Bill of Rights (the first 10 amendments), so it takes longer to get the whole Articles of Confederation to be approved, or ratified.
Hope this help, my English is not that well so please excuse for it.
I think none of them were great honestly. They should not have been accepted
