Before Sonya left for college, she told her friend Lacy that she thought sororities were filled with snobs and that she would never consider joining one. During Sonya's first week on campus, a sorority member invited her to a party and encouraged her to pledge. After Sonya attended the party, she told Lacy, "I think some sororities are filled with snobs, but this sorority does a lot of good things for the community. It’s really a service organization." Sonya's sentiments illustrate?

Sonya's sentiments illustrate the cognitive dissonance theory.

Explanation:

Cognitive dissonance theory states that individuals feel discomfort when their attitudes and behaviors are in conflict. For the discomfort to be nonexistent, there must be harmony between our beliefs and our reality. If we are introduced to knowledge that imbalances such harmony, discomfort will take place. That is the case with Sonya. She is now trying a common tactic to get rid of the discomfort. She has chosen to explain to herself and others that that one sorority is an exception, but other sororities are still filled with snobs. By doing this, Sonya finds balance between her beliefs and the reality she has just discovered.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
