Um....hm...lemme see....let's say D. It seems to be the most reasonable.
Explanation:
The executive branch carries out and enforces laws. It includes the president, vice president, the Cabinet, executive departments, independent agencies, and other boards, commissions, and committees. American citizens have the right to vote for the president and vice president through free, confidential ballots.
The significant consequences were that: 1. China became a Republic instead of a monarchy; 2. Foreign influences were brought to a minimum as the country almost closed its borders; 3. Increased provincial governance led to decentralization; 4. Social reforms and changes were conducted in a not as successful manner. <span />
Weather will be the primary reason. Despite its huge size. the real habitable area is probably less than 10% of its geographical size. Even Southern Ontario is deemed by many I know to be "too cold to live". 90% of Ontario and Quebec are simply inhabitable. I also personally think the entire Manitoba and Saskachewan are not suitable for human habitation unless we can create a way to simply hibernate during the 6 month winter (why there are so few people in Montana and North Dakota?) The fact that Montreal are thrive as a vibrant metropolis is already sort of a miracle and we don't see many such large cities with such severe weather. The only other case I can think of is probably Moscow.
