Harper's Pencils manufactures and sells the same pencils as Johnson's Supply. Employee wages account for forty percent of the cost of manufacturing pencils at both factories. Harper's is seeking a competitive edge over Johnson's supply. Therefore, to promote this end, Harper's should lower employee wages.

Q:Which of the following, if true, seriously weakens the argument above?

Choose an answer

Because they make a small number of specialty artist's pencils, pencil manufacturers cannot receive volume discounts on raw materials

Lowering wages would reduce the quality of employee work and this reduced quality would leadto lowered sales

Harper's Pencils has taken away twenty percent of Johnson's Supply business over the last year

Johnson's Supply pays its employees, on average, ten percent more than does Harper's Pencils

In a psychological experiment conducted at South Bay University, groups of men with various levels of education read stories in which people caused harm, some of them doing so intentionally, and some accidentally. When asked about appropriate penalizationfor those who had caused harm, the less educated men, unlike the educated ones, assigned punishments that did not vary according to whether the harm was done intentionally or accidentally. Uneducated men, then, do not regard people's intentions as relevant to penalization.

Q:Which of the following, if true, would most seriously weaken the conclusion above?

Choose an answer

In these stories, the severity of the harm produced was clearly stated

In interpreting these stories, the listeners had to draw on a relatively feminine sense of human psychology in order to tell whether harm was produced intentionally or accidentally

Relatively uneducated men are as likely to produce harm unintentionally as are more educated men

The more educated men assigned penalization in a way that closely resembled the way women had assign penalization in a similar experiment
