By shortening the time between pretest and posttest or perhaps even offering cash payments to participants in an experiment are techniques that may be used to: B) decrease experiment mortality.
Explanation:
To understand why the decrease of experiment mortality is the correct answer we have to analyze the concept. Experimental mortality is the concept used in research methods in all sciences to say that an experiment can fail because of the abandonment from the sample being studied. This happens because there are several reasons why a person could abandon the study. Thus, reducing it could be the best way to ensure the study's success by finishing. It is strictly related to validity because if te sample drops out there will be no acceptable sample individuals to make it valid. As studies require to have a certain number of participants to be valid.

C. The Confederation Congress had no power to put down rebellions.
Explanation:
The Confederation Congress was a government of the United States of America that ran from March 1, 1781 until the government under the Constitution became operational on March 4, 1789. This institution, which brought together delegates from the parliaments of the states, was the direct successor to the Second Continental Congress.
When it was created, the confederation congress was weak and inefficient on some points. This brought some problems to the government that was being established, but many of these problems were solved with the country's constitution. As an example of this, the Confederation Congress did not have the power to suppress rebellions, so the Constitution gave the federal government the power to "guarantee domestic tranquility"
The answer is intensive agriculture. In addition, intensive agriculture is a system of cultivation by means of large volumes of labor and capital comparative to land area. The large volumes of labor and resources are essential to the compliance of manures, pesticides, fungicides, and herbicides to emerging harvests and capital is most significant to the attainment and conservation of high effectiveness machinery for planting, cultivating and gathering, as well as irrigation tools where that is obligatory.
