Answer to Question 1

C

Answer to Question 2

As David Berliner has argued, schools and classrooms differ from each other in a number of ways, including quality and quantity of personnel, teaching methods, budget, leadership, and community support. In addition, cognitive and effective outcomes of schooling are affected by complex interactions among such factors as student characteristics, teacher characteristics, curriculum materials, socioeconomic status of the community, and peer influences. The result of all this complexity is that teaching methods and programs that work the same way for a broad sample of teachers and students in different school districts are few and far between.

It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
