Operant chamber is
laboratory apparatus consisted of the response lever, electrified grid and food dispenser.
Operant chamber (also known as Skinner’s box) is a
typical laboratory chamber (apparatus) in which the behavior and learning
process of rats was examined. This chamber is mostly empty, it has a food
dispenser, response lever which gives food when it’s pressed and sometimes
electrical greed. With this chamber, Skinner has learned in his research that
rats firstly press the lever by mistake, but that begins to happen more and
more. After some time, rats learn that when they press the lever they get food
as a reward. At the other experiment, rat have learned the same way that when
they press the lever, the electrified grid is turned off.

Hi, you've asked an incomplete question. The remaining part of the question reads;
the first paragraph;
<em>I spent my teens and much of my twenties collecting printed rejections. Early on, my mother lost $61.20—a reading fee charged by a so-called agent to look at one of my unpublished stories. No one had told us that agents weren’t supposed to get any money upfront, weren’t supposed to be paid until they sold your work. Then they were to take ten percent of whatever the work earned. Ignorance is expensive. That $61.20 was more money back then than my mother paid for a month’s rent.</em>
The last sentence of the first paragraph (“That . . . month’s rent”) primarily serves to
A. <em>justify an action by invoking an ethical principle</em>
B. clarify a point by defining an ambiguous term
C. show how anecdotal evidence supports a claim
<em>D. provide meaningful context for a revealing statistic</em>
<em>E. demonstrate that a common practice has harmful effect</em>
Answer:
<u><em>D. provide a meaningful context for a revealing statistic</em></u>
Explanation:
By saying, "<em>That $61.20 was more money back then than my mother paid for a month’s rent" </em>the narrator had revealed a very interesting statistic about the value of money back then.
In other words, the context surrounding the statement helps the average reader quickly understand that a month's rent used to be <em>lesser</em> than $61.20; very interesting statistics at that.
