Why might a nation become an ally with another nation?

Usually, it's because they have something the other person wants, like if Iraq has oil and the US wants it, and Iraq wants guns and the US has that, then the two countries could form an alliance based off of trade, and the alliance could only prosper if one side has what the other side wants. Also, if a side needed help with a war, they could ask countries for help, and usually they have to give something in return, like if Guyana needed help with fighting with Kirghizistan, and they reached out to the US, the US could help them, but after the war, Guyana had to provide the US with titanium (These are examples, not actual things.). Hope this helps!

answer: i looked it up

explanation: in 1955 in montgomery, alabama, a girl refused to give up her seat on a public bus. the girl was black, and the passenger looking to take her seat was white. this is a familiar tale, but it's not about rosa parks. the girl in the story is a 15-year-old high school student named claudette colvin, and this act of defiance occurred nine months before rosa parks did the same thing. colvin was arrested, and her case is what led to the u.s. supreme court's order for the desegregation of alabama's bus system. so, why don't we know colvin's name? "later i had a child born out of wedlock; i became pregnant when i was 16," colvin says. "and i didn't fit the image either, of, you know, someone they would want to show off.
