One parent picks up the child from daycare while the other parent goes to the grocery store and begins to make dinner. This is an example of which principle is at work?
The correct answer is There are gains from trade.
<h3>Why are there gains from trade?</h3>
The price of one commodity relative to the other commodity that the two countries agree to trade. Good trade conditions allow a country to import goods at a lower opportunity cost than the cost of producing goods domestically, thus benefiting the country from trade.
Trade is central to ending world poverty. Countries that are open to international trade tend to grow faster, innovate, be more productive, and provide people with higher incomes and more opportunities. Open trade also benefits low-income households by providing consumers with more affordable goods and services.

Answer:
d. dependent variable
Explanation:
In research, the independent variable is the variable that can be manipulated by the researchers and which will have an effect on another variable that is called the dependent variable. (Therefore, the variable in which the affect is perceived is called the dependent variable).
The researchers don't really have control over the dependent variable but it is the one that it's being tested and see how it responds to the independent variable.
In this example, the researchers want to see if depression has an effect on the negative emotions being remembered. We can see that they want to see if depression will have this effect. Therefore, since <u>depression might affect </u>the remembering of negative emotions, the negative emotions would be the dependent variable.
I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)
but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments
