Answer: B. Modern political parties and campaign tactics grew.
Is the question multiple choice?
The correct answer is all of them.
Indeed, A globe has one main advantage over maps, that it does not distort the exact scale of the size of a given country or territory, providing its user with an exact idea of the territorial sizes and differences between countries. Maps have to be distorted to a certain extent in order to make adapt them to a two-dimensional space from a three-dimensional one. The funny fact is that a spherical geoid distorts geological formations such as mountains and canyons since were these to be realistically imprinted on its surface they would be barely visible due to the very small scale of the globe. Otherwise the globe would have to be enormous, occupying the size of a large room in order to show a noticeable relief or carving for mountains or canyons.
Maps are very practical, they can be specialized in so many ways that globes cannot. They want provide far more detail that globes can and make it easier to compare nations between themselves and provide clear geodesic positioning for them. Changing the round space into flat space makes them incredibly practical as they can be easily put on a table with other documents where a globe would encumber them. And they are certainly easier to carry around than a globe. Now, the only caveat is that such advantages/disadvantages change when the globe is a virtual image like the one from Google Earth, but that is a different subject.
It would make checks and balances obsolete; one branch (lets take legislative) would be able to do whatever it sees fit without the other two branches balancing out the power. if most of the power shifted to one then the other two cant stop its decisions.
