1. Birds have been said to be descended from certain birdlike dinosaur species with which they share distinctive structural features. The fossil record, however, shows that this cannot be so, since there are bird fossils much older than the earliest birdlike dinosaur fossils that have been found.

Which of the following is an assumption on which the argument relies?

The birdlike dinosaurs have no descendants.

There are no flightless dinosaur species that have the distinctive structural features shred by birds and birdlike dinosaurs.

There are no birdlike dinosaur fossils that are older that the bird fossils but have nit yet been unearthed.

It could not have been the case that some birds were descendant from one of the bird like dinosaur species and other birds from another.

Birds cannot have been descended from dinosaur species with which the birds do not share the distinctive structural features.

2. Overuse of antibiotics often leads to a reduction in the effectiveness of the drugs; this theory has recently been bolstered by observations that people who regularly take antibiotics have fewer disease-fighting organisms in their bodies than do people who rarely take antibiotics.

If overused, one theory in regard to antibiotics becoming reduced in their effectiveness has recently been bolstered by observations that people who regularly take antibiotics have fewer disease-fighting organisms in their bodies than do people who rarely take antibiotics.

If overused, one theory regarding antibiotics becoming reduced in their effectiveness has recently been bolstered by observations that people who regularly take antibiotics have fewer disease-fighting organisms in their bodies than those who rarely take antibiotics.

The observation that people who regularly take antibiotics have fewer disease-fighting organisms in their bodies than do people who rarely take antibiotics has recently given support to one theory in regard to this phenomenon, if overused, antibiotics become reduced in their effectiveness.

The observation of people who regularly take antibiotics having fewer disease-fighting organisms in their bodies than do people who rarely take antibiotics has recently bolstered one theory about why antibiotics become reduced in their effectiveness.

4. Alice’s take-home pay last year was the same each month, and she saved the same fraction of her take-home pay each month. The total amount of money that she saved at the end of the year was 3 times the amount of her take-home pay that she didn’t save. If all money she saved last year was from her take-home pay, what fraction of her pay did she save each month?

5. Lightbox, Inc., owns almost all of the movie theaters in Washington County and has announced plans to double the number of movie screens it has in the county within five years. Yet attendance at Lightbox’s theaters is only just large enough for profitability now and the county’s population is not expected to increase over the next ten years. Clearly, therefore, if there is indeed no increase in population, Lightbox’s new screens are unlikely to prove profitable.

Which of the following, if true about Washington County, most seriously weakens the argument?

Though little change in the size of the population is expected, a pronounced shift toward a younger, more affluent, and more entertainment-oriented population is expected to occur.

The sales of snacks and drinks in its movie theaters account for more of Lightbox’s profits than ticket sales do.

In selecting the mix of movies shown at its theaters, Lightbox’s policy is to avoid those that appeal to only a small segment of the moviegoing population.

Spending on video purchases, as well as spending on video rentals, is currently no longer increasing.

There are no population centers in the county that are not already served by at least one of the movie theaters that Lightbox owns and operates.
