AT THE BEGINNING HE SEAMS ANGRY AND UPSET BUT IN THE END HIS WHOLE MOOD CHANGES
The answer is C. "the man's behavour led me to guess...upset in someone."
Sentences A and B describe the actions and manners, showing the man's behaviour and anxiety: casting quick glances, his foot beating on the hot pavement etc. appearing he could even explode with anger. At some point (C), <em>he changed and just got calm, wainting silently, leading the speaker to wonder if the cause of all this could be the bus' delay.</em>
After a procedur has been completed, some questions can be asked to help evaluate the results. Here are these questions:
1. Were the steps completed in order?
- This is important to ask because it may be necessary to change the order the next time the procedure is done.
2. What could be done differently in the future?
- This is important to ask because it can find problems with the procedure that was done to improve for the next one.
3. Was the expected outcome reached?
- If the expected outcome wasn't reached maybe the procedure shouldn't be repeated. Unless of course the surprise outcome was something good.
It was called the Weimer Republic. It was a democratic republic resembling (somewhat) the same sort of government the United States has. It failed for a number of reasons.
The first and most important was that the German population felt they had been sold down the drain. They felt that their government had failed them the moment the Versailles treaty was signed. There were many riots and uprisings that happened during the Republic. It was chaotic in Germany and unstable.
This anger that people felt had all the earmarks of "DO SOMETHING" and do it now. That psychology led to the rise of Hitler, although it was slow in coming. The treaty of Versailles had to be rewritten a couple of times simply because Germany was not paying. The terms were just too steep, but even if they were much more lenient, it wouldn't have made much difference. Germany was just too angry internally.
I would pick the last one, but it is awfully simplistic.
