In recent years, many cabinetmakers have been winning acclaim as artists. But since furniture must be useful, cabinetmakers must exercise their craft with an eye to the practical utility of their product. For this reason, cabinetmaking is not art.

Which of the following is an assumption that supports drawing the conclusion above from the reason given for that conclusion?

• Some furniture is made to be placed in museums, where it will not be used by anyone.
• Some cabinetmakers are more concerned than others with the practical utility of the products they produce.
• Cabinetmakers should be more concerned with the practical utility of their products than they currently are.
• An object is not an art object if its maker pays attention to the object's practical utility.
• Artists are not concerned with the monetary value of their products.

Physician: The hormone melatonin has shown promise as a medication for sleep disorders when taken in synthesized form. Because the long-term side effects of synthetic melatonin are unknown, however, I cannot recommend its use at this time. Patient: Your position is inconsistent with your usual practice. You prescribe many medications that you know have serious side effects, so concern about side effects cannot be the real reason you will not prescribe melatonin.

The patient's argument is flawed because it fails to consider that

• the side effects of synthetic melatonin might be different from those of naturally produced melatonin
• it is possible that the physician does not believe that melatonin has been conclusively shown to be effective
• sleep disorders, if left untreated, might lead to serious medical complications
• the side effects of a medication can take some time to manifest themselves
• known risks can be weighed against known benefi ts, but unknown risks cannot

In Asia, where palm trees are nonnative, the trees' flowers have traditionally been pollinated by hand, which has kept palm fruit productivity unnaturally low. When weevils known to be efficient pollinators of palm flowers were introduced into Asia in 1980, palm fruit productivity increased—by up to 50 percent in some areas—but then decreased sharply in 1984.

Which of the following statements, if true, would best explain the 1984 decrease in productivity?

• Prices for palm fruit fell between 1980 and 1984 following the rise in production and a concurrent fall in demand.
• Imported trees are often more productive than native trees because the imported ones have left behind their pests and diseases in their native lands.
• Rapid increases in productivity tend to deplete trees of nutrients needed for the development of the fruit-producing female flowers.
• The weevil population in Asia remained at approximately the same level between 1980 and 1984.
• Prior to 1980 another species of insect pollinated the Asian palm trees, but not as efficiently as the species of weevil that was introduced in 1980.
