Chinese Emperor Qianlong response to outside influences.

Qianlong, the emperor of China, in response to Lord Macartney wrote a letter to King George III.  He states that the Chinese and the British way of life is different that he was not interested in developing a trade relationship between the two powers.

Hope this helps!

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
