A researcher develops a questionnaire to assess the personality trait of impulsivity among adults. In a journal article, he presents evidence that college students tend to get essentially the same score if they take the test twice, 3 months apart. He also presents the average score, the highest score, and the lowest score obtained by two large samples; one done with 3,000 college students and another done with 1,750 adults who are not in college. However, when one reviews the sample questionnaire items, it seems clear that they relate more to whether a person is sociable, outgoing, and fun than to whether an individual is impulsive. As a result, one would question the _______ of the researcher’s questionnaire.
A) standardization
B) reliability
C) reliability and validity
✔️D) validity✔️

2. The Kshatriyas - This was the ruling and warrior varna, made up of kings, generals, soldiers, and their families. The whole society counted on them for guidance and protection, and they were expected to learn religion from the Brahmans and maintain high standards of ritual purity.
3. The Vaishyas - This was a practical varna composed of craftspeople, traders, merchants, and farmers. They had the important jobs of growing food and keeping the society's economy running smoothly.
