Read the passage.
What purpose does the juxtaposition serve in the passage?
Imagine that a person pays taxes to the government, but has
no say in how the government uses the money. This
situation is very real for teenagers with jobs. The voting age
in the United States is 18, but many teenagers start to work
when they are 16. This means some teenagers have to pay
taxes but do not have a voice in elections. The voting age
should be lowered. As the Founding Fathers said, "No
taxation without representation."
It suggests that teenagers should not pay taxes.
It argues that teenagers should earn their money.
It explains why teenagers should be allowed to vote.
It emphasizes that many teenagers should work harder.

one context clue that me find the meaning of luxuriance was that the base word of luxuriance is luxury, so i think that luxuriance means something that is luxury, or something luxurious.

where is the sentence at?

personaly i think it is a hope this !

the passage can be best described as: "the british legislature extended an unwarranted jurisdiction".

we can say that because the text clearly states how the people of the colonies warned the british about their excessive desire to rule over them, without taking into consideration the difficulties their brothers had experienced in america: they struggled to establish the colonies, to adapt to new types of weather, fight with the natives, etc., and how they now see (or then saw) the only way out was to cut all ties with the british, since they ignored the people's petitions.
