The average price of chicken in the United States was $1.50 per pound from 1995 to 1999 and $2.00 per pound from 2000 to 2004, an increase of about 33 percent. Meanwhile, the average consumption of chicken per capita per year from 1995 to 1999 was 100 pounds; the corresponding figure for 2000 to 2004 was the same. It seems, then, that rising chicken prices have no effect on consumers’ decisions.
The conclusion above would be more properly drawn if we knew that:
(A) Inflation did not increase the price index by as much as 33 percent from the first period to the second and thereby make the real prices between the two periods equal.
(B) Average per capita income in the United States was less than 33 percent higher from 2000 to 2004 than from 1995 to 1999.
(C) The average price of beef during 2000 to 2004 was not higher than it was from 1994 to 1999, so that consumers looked for alternatives.
(D) In general, American consumers are price-insensitive.
(E) From 2005 to 2009, the average price of chicken in the United States will reach $2.67 per pound but the average consumption of chicken per capita per year will remain 100 pounds.
