Well, 
The answer would be the number 3
why? because in the beginning when Ferdinand de Lesseps, a french engineer who built the swiss canal decided to create one in the isthmus of Panama due to its ideal location and width to save a lot of time and money on travels, they brought over from France workers and machines, used to create the swiss canal previously, but due to the clay soil and the tropical conditions they quickly broke, forcing workers to do most of the work manually.
Also, due to the heat and the still water, mosquitoes carrying different diseases like malaria and dengue, swarmed the area biting and infecting the workers, ultimately killing most.
Making them give up the whole project.

This question refers to the lynching of Emmett Till.
This question refers to the moment in which Till was flirting with Carolyn Bryant. Although Till believed that his actions were relatively harmless, the older man warned him against them, as he knew they could lead to trouble.
This older man was a local, so he understood the social rules that regulated interactions between black and white people in the South. He knew how these interactions often led to problems for black people. He most likely learned the rules through the process of socialization that he engaged in from the moment he was born. They were passed down to him through his parents, friends, relatives, neighbours, etc. These rules are often enforced in a social way, not through law, but through the actions of the community. In this case, they were enforced through violence and murder.
