The answer is (A) Greg’s education was covered by a donation, and Hunter’s education was covered by taxes.
This is due to the fact that Greg has a benefactor, which is <em>someone who gives his or her money to help another person</em> – in this case, the benefactor is donating their money for Greg’s private schooling.
In Hunter’s case, he doesn’t have to pay for tuition because his public school students' tuition is paid using the citizen’s taxes.
Countries would be able to increase their productivity for the services with comparative advantage. A country then can sell products they produce efficiently and also would buy from other nations the products that they cannot produce. The comparative advantage can lose if there are competitors operating in a low wage country.
Convection currents are vertical circular movements of fluids that transfer energy due to changes in density.
Answer:
a. <em>Independent - </em>age; <em>Dependent - </em>intelligence
b. Cross-sectional
Explanation:
Scientific experiments label the variables that they employ in two ways: dependent and independent. Independent variables are those that are changed or manipulated by the researchers. In this case, the researchers are exercising control over the variable of age by selecting a particular type of people. This also means that the researchers believe this variable to have a direct effect on the dependent variable.
On the other hand, dependent variable refers to the variable being tested and measured. It receives this name because the variable is "dependent" on the independent variable. In this case, intelligence is the variable that is believed to depend on age.
Finally, this is also an example of a cross-sectional study. Cross-sectional studies interview different samples of people at a particular point in time. This allows us to have a snapshot of a group at a particular moment. This is different from longitudinal studies, which follow the same sample of people over a long period of time.
