"To compare the leadership of different countries across Europe".

Explanation:

In the mentioned section, the author talks about Roosevelt becoming president, only a day before Hitler gaining control of Germany. This opening line shows how he is trying to put two different leadership methods against each other. He continues explaining how dictatorship was getting stronger in East Asia and parts of Europe, including Spain, while America, Britain, and France were on sidelines, not willing to confront these changes. The passage, therefore, talks about different relationships of the government, their leading styles, and how different it all was.

The author does mention Hitler's promises and the Treaty of Versailles, but not the reactions to it. Additionally, he does not explicitly say all of this was the effect of WWI and directs leads to WWII. He simply talks about different governments, their leading styles, and differences.

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:
