PROBLEM: Passage: African Americans made up 41 percent of death row inmates while making up only 12.6 percent of the general population. (They have made up 34 percent of those actually executed since 1976.) However, that number is lower than that of prison inmates, which is 47 percent. According to the US Department of Justice, African Americans accounted for 52.5% of homicide offenders from 1980 to 2008, with whites 45.3% and Native Americans and Asians 2.2%. This means African Americans are less likely to be executed on a per capita basis. However, according to a 2003 Amnesty International report, blacks and whites were the victims of murder in almost equal numbers, yet 80 percent of the people executed since 1977 were convicted of murders involving white victims. 13.5% of death row inmates are of Hispanic or Latino descent, while they make up 17.4% of the general population.

SOLUTION: What percentage of American death row prisoners are South American

PROBLEM: Passage: Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Some basic emotions can be modified to form complex emotions. The complex emotions could arise from cultural conditioning or association combined with the basic emotions. Alternatively, similar to the way primary colors combine, primary emotions could blend to form the full spectrum of human emotional experience. For example, interpersonal anger and disgust could blend to form contempt. Relationships exist between basic emotions, resulting in positive or negative influences.

SOLUTION:  What isn't the name of the theory Plutchik created?

PROBLEM: Passage: In 1986, Michael Dell brought in Lee Walker, a 51-year-old venture capitalist, as president and chief operating officer, to serve as Michael's mentor and implement Michael's ideas for growing the company. Walker was also instrumental in recruiting members to the board of directors when the company went public in 1988. Walker retired in 1990 due to health, and Michael Dell hired Morton Meyerson, former CEO and president of Electronic Data Systems to transform the company from a fast-growing medium-sized firm into a billion-dollar enterprise.

SOLUTION:
What year didn't Michael Dell bring in Lee Walker to the company?
