<span>The population explosion was caused by two things. One was the
natural birthrate of the colonists. Partly because of the time-honored farm family tradition that large families meant more people to work (and maybe because there wasn’t much else to do on those long winter nights in the country), the size of many American families was astounding.

But the growth was by no means all from within the colonies. Immigration was the second factor in the population explosion. It continued at a brisk pace, not only from England but also from other Western European countries.
The answer is patterned.
Nozick’s theory of justice claims Distribution is based solely on the final outcome (how it came about)
On the other hand, justice according to Rawls’ Difference Principle depends entirely on the distribution pattern within the society.
The answer is "<span>drive-reduction theory".</span>
The theory<span> was presented by behaviorist Clark Hull and further created
by his partner Kenneth Spence. As per the hypothesis, the reduction<span> of drives</span><span> is the essential
power behind inspiration. While the drive<span>-reduction theory was at
one time a prevailing power in brain research, it is to a great extent
overlooked today. </span></span></span>
