I found these CR's (& their answers) a bit off... :x
Just wanna make sure by knowing your answers...

1. Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.
Which of the following, if true, would most weaken the argument above?
(A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.
(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.
(C) Employers often hire extra help during holiday and warm weather seasons.
(D) The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s.
(E) The teenage unemployment rate has occasionally declined in the years since 1960.

2. A recent survey of all auto accident victims in Dole County found that, of the severely injured drivers and front-seat passengers, 80 percent were not wearing seat belts at the time of their accidents. This indicates that, by wearing seat belts, drivers and front-seat passengers can greatly reduce their risk of being severely injured if they are in an auto accident.
The conclusion above is not properly drawn unless which of the following is true?
(A) Of all the drivers and front-seat passengers in the survey, more than 20 percent were wearing seat belts at the time of their accidents.
(B) Considerably more than 20 percent of drivers and front-seat passengers in Dole County always wear seat belts when traveling by car.
(C) More drivers and front-seat passengers in the survey than rear-seat passengers were very severely injured.
(D) More than half of the drivers and front-seat passengers in the survey were not wearing seat belts at the time of their accidents.
(E) Most of the auto accidents reported to police in Dole County do not involve any serious injury.

3. Six months or so after getting a video recorder, many early buyers apparently lost interest in obtaining videos to watch on it. The trade of businesses selling and renting videos is still buoyant, because the number of homes with video recorders is still growing. But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times.
Which of the following, if true, would most seriously weaken the conclusion above?
(A) The market for video recorders would not be considered saturated until there was one in 80 percent of homes.
(B) Among the items handled by video distributors are many films specifically produced as video features.
(C) Few of the early buyers of video recorders raised any complaints about performance aspects of the new product.
(D) The early buyers of a novel product are always people who are quick to acquire novelties, but also often as quick to tire of them.
(E) In a shrinking market, competition always intensifies and marginal businesses fail.

Vicky:

The first is really weird, I did it myself and made a mistake as well. Now I agree it's simply off the point.
Other 2 are correct.
Second: Answer B.
Just try to pick numbers and test this logic. The solution lies in pure mathematics. To be sure that seat belts are really crucial, you must be convinced that those 20% unscathed represent far more than 20 percent of total number of drivers. Otherwise the proportion of wearing seat belts&hurt and those not wearing seat belts&unhurt is equal.

Third: Answer B.
Assumption: Only growng number of VCR buyer's keeps the market alive.
Fact: existing VCR owners will rent and buy videos cause many films are specifically produced as video features.

Any other ideas? :roll:

About first one.

I found it not so difficult.

Argument obviously assumes that high wages are the only (or most important) determinant of high unemployment among teens.

For B it is clear that THERE ARE OTHER REASONS besides rising wages.

So B - weakening the argument

Hope this helps!

Misha:

I could agree with you only given the fact that in this particular case we don't have better (stronger) argument suggesting there must be some other reason for high unemployment rate.

The argument does not explicitly state that rising unemployment rate was necessarily followed by rising subminimum wage for teens (the point you are trying to make).
Just on the contrary - the argument say "if Congress institutes a subminimum wage, a new lower legal wage for teenagers", which assumes it had already been constant for a long time. (If it had been changing, they should have said if Congress fixes a minimum wage on a certain level to prevent from rising).

Bottom line: I don't like this question 8-)
