Under new imperialism, Europe did not need large numbers of people to control territories because of:

(B) Improved transportation, communication, and other advantages.

The decades of European leadership over their old colonies did not influence the control of new territories. The countries, cultures, and political situations were so variable. The European experiences may have taught some important rules to new settlers, but it was not enough to allow them to lead better with fewer people.

The new settlers did not rely at all on the governments in place in their colonies to gain influence. When Europeans occupied new land, they took control of its politic and all parts of society.

The major change that happened at the end of the 18th century and in the first half of the 20th century was the development of transport and telecommunication. For example, the phone appeared in 1880 and the airplanes around 1910. In that time, the weapons became more efficient and helped better to stop the rebellions as well. All of these developments made easier the controlling over colonies.
