SOCI 1301 Self Fulfilling Prophesy Questions

I’m stuck on a Sociology question and need an explanation.

1. How does the “self-fulfilling prophesy” apply to the way teachers and students act in a school?
2. Identify factors that lead to differential access to higher education.
3. Explain how standardized testing and tracking have historically worked to the disadvantage of the poor and minorities.
4. Summarize ways in which various socialist and capitalist societies supply health care to their citizens.
