Answer:
To avoid the ethical issues a true experiment would cause.
Explanation:
A quasi-experiment is a factual conventional study that is used to calculate the causal effect of interference on a target population without an irregular function. Quasi-experimental research shares closeness with traditional experimental design or randomized controlled trials, but lacks the element of random assignment specifically for treatment or control.
Instead, quasi-experimental designs typically allow the researcher to control the assignment to treatment status, but use some criterion other than random assignment (For example- an eligibility cutoff mark).
While not all land is suitable for agricultural, farmers can use irrigation and fertilizer to make land arable.
Much debate, however, is centered on the impact of agriculture on early humans. Advances in agriculture and the domestication of animals in such places as Mesopotamia allowed people to form semi-sedentary and sedentary settlements, which led to the development of complex societies and civilizations.
hope this helps get a good grade :)
