Mary would start with a hypothesis such as, "I believe that plants with no soil will not grow because there are no nutrients coming from the soil for the plant to grow"
Then she would put the plan in place to start her experiment. She will get the same type of seeds, the same amount of water and sunlight. The only difference between the 3 plants is that one plant will have no soil, the second plant will have 1 inch of soil, the third plant will have the correct amount of soil.
She will run the experiment for 2 weeks to see whether the plants have grown and what the conclusion is. She will record how much the plants have grown every day, she will measure the height of each plant.
At the end of 2 weeks, she will gather all her data and come to a conclusion.
True, in order to make their mercantilist economy succeed Britain needed to import raw materials from its colonies
I would say that B is the most accurate. This is because:
Pull factor is something that makes someone want to <em>arrive </em>in a new country.
Push factor is something that makes them want to <em>leave </em>an old country.
B states that fighting in a homeland, something that a normal civilian wouldn't want to take part in, would make someone want to <em>leave</em> their country.
So, the answer is B!
In short, Libertarians believe the government should never violate an individuals rights (socially liberal), and should be extremely limited its power, especially in regards to the economy (economically conservative).
Carried forward, Libertarians generallysupport gay rights, a woman's right to choose ("pro-choice"), and an individuals privacy (opposed to the Patriot Act, and to a degree also opposed to the CIA). Anything that expands the individuals' rights, Libertarians support.
Economically, Libertarians generally believe that Capitalism should be unregulated. There are some blatant problems with monopoly and scams (i.e. Ponzi schemes), and a certain number of Libertarians believe there ought to be some regulation.
In a similar vein, Libertarians generally are opposed to the power of the monopoly called government. As a political philosophy, Libertarians believe the government should exist only to protect the liberties of its citizens. A strong military is acceptable, but Libertarians favor the philosophy of the founding fathers - nonintervention.
These "policies" are only as I understand them, and should not be taken as representative of all Libertarians.
