What does this type of text structure highlight? What is the cause?
I don't think any segregation law angered black people in
Montgomery more than bus segregation. And that had
been so since the laws about segregation on public
transportation had been passed. That was back in 1900,
and black people had boycotted Montgomery streetcars
until the City Council changed its ordinance so that
nobody would be forced to give up a seat unless there was
another seat to move to. But over the years practices had
changed, although the law had not.
