"All Men are Created Equal" has changed since the Declaration of Independence
Think back to when slavery was still happening. Slavery was inhumane, and should have never happened. Slavery showed that NOT all men were created equal, just because of their and skin color. The Civil War was a historical event that showed that people wanted to fight for slavery to end, and eventually, thanks to the South, it did. So, "All Men are Created Equally" has changed because now people actually think that it is true. Racism is starting to go down.

The Silk road was much more because it was the only way to connect to China and trade with them. Chinese people were inovators and were not just simple traders. Thanks to the Silk road Europeans could get silk and spices and fireworks and gunpowder and numerous other inventions that were not found anywhere else in the world. If it hadn't been for Silk road Europe would've been much less developed.
all summer long, a group of men huddled in a stifling hot room in Philadelphia (Madison almost passed out from the heat) to develop the framework for a government that would govern the newly independent states of America.
"A" is quite correct, though "C" adds a bit more detail of how soldiers felt about Trench Warfare. In my honest opinion, I think "D" is the correct answer.
Trench Warfare was rather horrific, and brutal to say the least -- it was also "boring" during stalemates if neither party was engaging in any sort of push.
Note: I'm not a teacher of any sorts! This is just my opinion from things I've learned in the previous years.
