masya89 [10]

Answer:

Cultural diffusion

Explanation:

The Cultural diffusion was made possible first through the trade, since the economic activity often impacts many other key areas of life.

<em>In the this case , Buddhism originally from India came through the Silk Road and subsequent trade routes that stretched into China at the time Han Dynasty ruled.</em>

Difference between first past the post system and proportional system??​
bulgar [2K]

Answer:

In the first past the post system, as the name implies, the party or candidate winning the a plurality of votes obtains all the political seats being contested.

For example, suppose we have three parties, and 20 seats being contested in a fictional election. The results are:

Red party - 60%

Green party - 30%

Blue party - 10%

Under a first past the post system, the Red Party would obtain all the 20 seats.

Under a proportional system, on the other hand, each party or candidate gets a proportional amount of seats corresponding to the percentage of the votes.

For example, if the number of seats contested is 20, and we obtain the same results as above, the number of seats for each party (in bold) would be:

Red party - 60%  - 12 seats

Green party - 30% - 6 seats

Blue party - 10% - 2 seats
