The SAT (Scholastic Aptitude Test) is often used as a signaling device by colleges to find high- qualified students.
 
  High scores on this test can certainly communicate a lot of other qualities about a student that may make it an efficient sorting device. However, can you think of any reason why at least occasionally a high score might not signal the correct information?

  C. both demand and supply decrease and the price might rise, fall, or not change; demand increases and the price rises

Answer to Question 1

Since students are well aware that colleges and universities rely heavily on SAT scores they are likely to spend quite a bit of time, effort and money to earning high scores. In other words, since a lot of effort is expended on this one instrument it might not necessarily reflect on the overall quality of the student.

Answer to Question 2

A Selling their used cars increases the supply of used cars. Buy-ing new hybrids increases the demand for hybrids.
