"which of the following situations illustrate the problem of the introduction of new goods in the construction of the cpi? check all that apply. a. increased personal computer purchases in response to a decline in their price b. the introduction of air bags in cars c. greater use of fuel-efficient cars after gasoline prices increase d. the invention of cell phones e. more scoops of raisins in each package of raisin bran"

(b)The introduction of air bags in cars  

(e) More scoops of raisins in each package of Raisin Bran.

Explanation:

If the quality of a good decreases from one year to the next  while the price of item remains the same  then obviously value of a dollar falls . Therefore you are getting a lesser good for the same amount of money.  Similarly, if quality rises the value of dollar increases.

Therefore, the introduction of air bags in cars  and more scoops of raisins in each package of Raisin Bran  illustrate the problem of the introduction of new goods in the construction of the CPI.
