CRITICAL REASONING

(6 questions)

1) In Los Angeles, a political candidate who buys saturation radio advertising will get maximum name recognition.

What does the statement above logically convey?

(a) Radio advertising is the most important factor in political campaigns in Los Angeles.

(b) Maximum name recognition in Los Angeles will help a candidate to win a higher

percentage of votes cast in the city.

(c) Saturation radio advertising reaches every demographically distinct sector of the

voting population in Los Angeles.

(d) For maximum name recognition a candidate need not spend on media channels other

than radio advertising.

(e) A candidate’s record of achievement in the Los Angeles area will do little to affect his

or her name recognition there.

2) A newly discovered disease is thought to be caused by a certain bacterium.

However, a recently released research notes that the bacterium thrives in the presence of

a certain virus, implying that it is actually the virus that causes the new disease.

Which of the following, if true, would most strengthen the argument above?

(a) In the absence of the virus, the disease has been observed to follow infection by the

bacterium.

(b) The virus has been shown to aid the growth of bacterium, a process which often leads

to the onset of the disease.

(c) The virus alone has been observed in many cases of the disease.

(d) In cases where the disease does not develop, infection by the bacterium is usually

preceded by infection by the virus.

(e) Onset of the disease usually follows infection by both the virus and the bacterium.

3) The local high school students have been clamoring for the freedom to design their

own curricula. Allowing this would be as catastrophic as allowing 3-year- olds to choose

their own diets. These students have neither the maturity nor the experience to equal that

of the professional educators now doing the job. Which of the following statements, if true, would most strengthen the argument above?

(a) High school students have less formal education than those who currently design the

curricula.

(b) 3-year- olds do not, if left to their own devices, choose healthful diets.

(c) The local high school students are less intelligent than the average teenager.

(d) Individualized curricula are more beneficial to high school students than are the

standard curricula, which are rigid and unresponsive to their particular strengths and

weaknesses.

(e) The ability to design good curricula develops only after years of familiarity with

educational life.

4) The rate of violent crime in this state is up 30% from last year. The fault lies entirely in

our court system: Recently our judges’ sentences have been so indulgent that criminals

can now do almost anything without fear of a long prison term.

The argument above would be weakened if it were true that:

(a) 85% of the other states in the nation have lower crime rates than does this state.

(b) White-collar crime in this state has also increased by over 25% in the last year.

(c) 35% of the police in this state have been laid off in the last year due to budget cuts.

(d) Polls show that 65% of the population in this state opposes capital punishment.

(e) The state has hired 25 new judges in the last year to compensate for deaths and

retirements.

5) Because of a serious recent drought in Florida during the orange-growing season, the

price of oranges will be three times higher than the usual price. This will drive up the cost

of producing orange juice, pushing up the prices for the consumer.

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

(a) The recent drought was not as severe as scientists predicted.

(b) States other than Florida also supply oranges to juice manufacturers.

(c) Other ingredients are used in the production of orange juice.

(d) Last year the price of oranges was lower than the average price over the last years.

(e) The price of oranges will eventually be $0.58 per crate.

6) All German philosophers, except for Marx, are idealists.

From which of the options below can the statement above be most properly inferred?

(a) Except for Marx, if someone is an idealist philosopher, the he or she is German.

(b) Marx is the only non-German philosopher who is an idealist.

(c) If a German is an idealist, the he or she is a philosopher, as long as he or she is not

Marx.

(d) Marx is not an idealist German philosopher.

(e) Aside from the philosopher Marx, if someone is a German philosopher, the he or she is

an idealist.
