TED Talk speakers are generally known to be effective public speakers.
What are some mannerisms or things
you notice about this speaker that
makes him/her a good public speaker
or a “not so good" public speaker?

Things that I notice are that they're confident when they're speaking. The topic that they chose is something that they are very passionate about. Their confidence is something that gets the crowd more engaged. I also notice that they also have humor in their TED Talks, That can really help the audience more engaged as well and it also shows that sometimes it's ok to have some fun here and there. One bad and good thing that I notice is that sometimes they're really sweaty when they talk and that may not attract the crowd a lot of the times. It's also a good thing because it just shows that they're working hard. Overall I think that public speakers are good(most of them)

Explanation:

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
