Answer:
Foot-in-the-door technique.
Explanation:
This technique involves having an individual do something small so that, in the long game, you manage to convince them of doing something bigger. In this case, wearing a button that says "adopt a dog today" would be a small feat to accomplish. After some weeks of wearing that, you ask this same person to adopt a dog. In this scenario, you would have greater chances of convincing them if they wore the button.
Eli Whitney invented a machine that made a great impact on American history. The cotton gin made it easier to separate the cotton seeds from the cotton fiber. The cotton gin (that Eli Whitney invented and the versions that was later made by others) made cotton planting so profitable that it increased demand for land and slave labor. It grossly contributed to the import of over 80 000 Africans. There were so many, a third of Southerners are slaves. The invention augmented the conflict that has led to the Civil War.
A country experiencing<u> inflation </u>is seeing supply surpass demand; as a result, the price of goods and services increase, and the country’s currency loses value.
<u>Explanation:</u>
A quantification of the rate at which an economy highers the average range of costs over a particular time of a basket of chosen products and services is understood as an Inflation. Inflation often represented as a percentage and may implies a decline in the purchasing power of the currency of a country.
It is not beneficial to the economy or individuals whenever inflation is too extreme of course. Inflation will always diminish money value, unless interest rates go up than inflation. And the higher the inflation, the less likely the savers would see any real value for their money.
Comedy routines that are mildly amusing in an uncrowded room seem funnier in a densely packed room is an example of social facilitation.
Social facilitation is a social psychological phenomenon that refers to the tendency for people to perform better on simple tasks when they are in the presence of other people.
The phenomenon was first identified by Norman Triplett in 1898, who found that cyclists rode faster when racing in the presence of others.
There are a number of explanations for social facilitation. One theory is that the presence of others serves as a source of motivation, leading people to try harder to succeed. Another explanation is that the presence of others provides a level of distraction that helps people focus on the task at hand.

<u>Question 1</u>
The correct answer is: "The researchers administered a questionnaire to obtain their data without trying to influence an explanatory variable of the study".
An observational study is one in which the researcher observes the effect of a variable without manipulating the conditions that surround the exposure or the subjects who are exposed to it. In this example, he simply hands out questionaires to the 353 individuals that compose the sample drawn from the population of interest: 12-year old teenagers.
<u>Question 2</u>
The correct answer is: "a cohort study".
The researcher is interested on a population group where all the components share a common characteristic (12-year old) and therefore they all belong to the same cohort. Subsequenly, he evaluates the differences between the ones who have been exposed to the explanatory variable (having a video console in the bedroom) and those who have not.
