The correct answer is C. Reference groups
Explanation:
In sociology which is the field that studies society and social structures, human groups can be classified into different categories including primary/secondary groups, out/in groups and reference groups. In the case of reference groups, this includes classmates, co-workers and any other peer that mainly works as a reference for the individual in terms of standard of measurements. Indeed individuals in reference groups observe others and behave according to other people in order to fit. This can be seen in the case presented as a student is in a basketball team and she has not received an academic award her peers had, which makes the student measure herself in comparison to others that are a reference and in the same way other students mock at her because she does not fit in the group.
The correct answer is :
An upper body performance test known as the sitting medicine ball throw (SMBT) is used to assess muscular health in older people. The aim of this study was to assess the test-retest reliability and validity of the SMBT in older women. In this study, 35 ladies (mean age: 75.15 + 6.39 years) took part. Over the course of three sessions, subjects completed SMBT trials utilising standard ball masses (SMBT4 lb and SMBT3 kg). On the first day, instruction in the SMBT and chest press 1 repetition maximum (CP1RM) was given. The tests were repeated on day 2, but data were recorded. On day 3, SMBT was retested, and then chest press peak power (CPPP) values between 30 and 80 percent of CP1RM were assessed.
The CPPP and SMBT4lb (r = 0.775, p 0.001) and SMBT3kg (r = 0.734, p 0.001) exhibited significant relationships (p 0.05), and the SMBT distance showed expected ageing reductions (r = -0.724 to -0.626, p 0.001), proving its validity. There was found to be high reliability between testing days, and Bland-Altman plots revealed few locations that deviated significantly from the bounds of agreement. The SMBT is a valid and incredibly trustworthy instrument that health providers can use to track upper body muscular power deficits in older women and enhance treatment regimens.

Answer:
4. people must make trade-offs.
Explanation:
Scarcity is the shortage of supply with respect to demand. It arises due to unlimited wants contrasted with limited resources - having alternative uses.
Scarcity : Demand > Supply
This leads to trade off (sacrifise) of something to attain anything, since the limited resources are short of unlimited wants & have alternative uses.
Eg : Having fixed money income (analogous to resources) & many commodities in consumption basket (analogous to wants); if one commodity is gained - it would be at the cost of sacrifising (trade off) some other commodity.
<span>The theme of the poem from Edgar Allan Poes' "To One in Paradise" in the third stanza reveals that there are losses from which people do not fully recover. It presents the audience about how the narrator feels that his life is nothing without his loved one and that no matter what he did in order to forget the pain, he just could not forget her.</span>
