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).

But understand this, that in the last days there will come times of difficulty. For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, heartless, unappeasable, slanderous, without self-control, brutal, not loving good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, having the appearance of godliness, but denying its power. Avoid such people.
There are two answers for this question, BUT, I say D is the best of these two
A. Their trading boats were unable to go past them;
D. The Egyptians used them as a defense against the Kush's armies;
The cataracts on the river Nile are part of the river where the waters are shallow, and there's also lots of rocks that are very close to the surface of the water. This makes them unsuitable for boats and for the Kush that was a big problem. The cataracts were limiting Kush to only perform trade and military actions on land, and Egypt used that advantage to the maximum.
The Nile cataracts can be used for sailing with boats but only when there's flood, so that is only in a very short period of time, and not to mention that when there's flood the waters are very unpredictable and can be fatal.
