Based on my information, your correct answer would actually be the very first option. When the city was actually well protected, they're still people that could still come in and repelled and attacks from the invaders. But this is what those other people have thought, they were not able to actually break in. They were so armed and protected as a small little city, they were not able to break in the city at any point. This would be the reason to why the Constantinople didn't fall until 1453. Your answer would then be the first option as it would read the following: "<span>The city was well protected and repelled attacks by Invaders".</span>
Since there is no background information, I would assume they could be going on strike.
I'm pretty sure his biggest objective in the civil war was to (B.) which is Save the Union.
1.8 Million people were at his inauguration.
So a social contract is where a "persons' moral and/or political obligations are dependent upon a contract or agreement among them to form the society in which they live".
Rousseau was most famous for coming up with the term but examples have always existed and exist right now.
An example of how a social contract works would be the legal system. For augments sake, if I say you stole all my money and you deny it, instead of fighting it out with fists or me raiding your house to find it with a gun, we both put our faith in the legal system which we both agree will be more impartial, and get to the truth. I surrender my right to take matters into my own hands on the condition that you will also do the same. Why did we do this? Because there are more benefits than not having this system in place. I may not be able to get personal revenge on you for stealing my money but I also am protected from people doing the same to me. People who are born in a state metaphorically "sign" the contract when they are born in order to live in the state.
A primitive example if you want would be that two people meet in the woods looking for berries. Both have guns and are distrustful of the other. They are constantly looking over their shoulders at each other out of fear which prevents them from going about their berry gathering. Eventually they both agree to a "contract" that they will both give up their guns at the same time. They do this because whilst you do not want to give up your gun, it means that you don't have to worry about getting shot in the back so times are more productive.
The theory is the same even if people disagree on why social contracts exist. Folk like Rousseau thought that social contracts arose because at the end of the day, humans are more interested in personal liberty and life and wish to avoid conflict as much as possible. More pessimistic people like Hobbes thought it was because humans are so naturally warlike that we needed social contracts to prevent our own violent natures.
