[Q]: Passage: For more than 40 years, Paul Ekman has supported the view that emotions are discrete, measurable, and physiologically distinct. Ekman's most influential work revolved around the finding that certain emotions appeared to be universally recognized, even in cultures that were preliterate and could not have learned associations for facial expressions through media. Another classic study found that when participants contorted their facial muscles into distinct facial expressions (e.g. disgust), they reported subjective and physiological experiences that matched the distinct facial expressions. His research findings led him to classify six emotions as basic: anger, disgust, fear, happiness, sadness and surprise.
[A]: Who has agreed that emotions are discrete?


[Q]: Passage: Instruction is the facilitation of another's learning. Instructors in primary and secondary institutions are often called teachers, and they direct the education of students and might draw on many subjects like reading, writing, mathematics, science and history. Instructors in post-secondary institutions might be called teachers, instructors, or professors, depending on the type of institution; and they primarily teach only their specific discipline. Studies from the United States suggest that the quality of teachers is the single most important factor affecting student performance, and that countries which score highly on international tests have multiple policies in place to ensure that the teachers they employ are as effective as possible. With the passing of NCLB in the United States (No Child Left Behind), teachers must be highly qualified. A popular way to gauge teaching performance is to use student evaluations of teachers (SETS), but these evaluations have been criticized for being counterproductive to learning and inaccurate due to student bias.
[A]: What is the opposite term used for instructors?


[Q]: Passage: During the rule of the Fatimid and Mamluk dynasties and their successor states in the medieval Middle East, many of the ruling elite founded madaris through a religious endowment known as the waqf. Not only was the madrasa a potent symbol of status but it was an effective means of transmitting wealth and status to their descendants. Especially during the Mamlūk period, when only former slaves could assume power, the sons of the ruling Mamlūk elite were unable to inherit. Guaranteed positions within the new madaris thus allowed them to maintain status. Madaris built in this period include the Mosque-Madrasah of Sultan Ḥasan in Cairo.
[A]:
Which class of people founded the madaris during the ancient period?
