How can social promotion lead to lower academic standards

Social promotion is the most common name for the policy of promoting students to the next grade level despite poor achievement at their current grade level. It is motivated by a desire to protect the social adjustment and school motivation of struggling students, as well as a belief that these students will get more from exposure to new content at the next grade than they would from repeating their current grade.

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.
