37. editorialist: drivers with a large number of demerit points who additionally have been convicted of a serious driving-relative offense should either be sentenced to jail or be forced to receive driver reeducation, since to do otherwise would be to allow a crime to go unpunished. only if such drivers are likely to be made more responsible drivers should driver re-education be rmended for them. unfortunately, it is always almost impossible to make drivers with a large number of demerit points more responsible drivers.

38. amphibian populations are declining in numbers worldwide. not coincidentally, the earth's ozone layer has been continuously depleted throughout the last 50 years. atmospheric ozone blocks uv-b, a type of ultraviolet radiation that is continuously produced by the sun, and which can damage genes. because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to uv-b radiation. in addition, their gelatinous eggs lack the protection of leathery or hard shells. thus, the primary cause of the declining amphibian population is the depletion of the ozone layer.

each of the following, if true, would strengthen the argument except:

(a) of the %26amp;lt;i%26amp;gt;var%26amp;lt;/i%26amp;gt;ious types of radiation blocked by atmospheric ozone, uv-b is the only type that can damage genes.

(b) amphibian populations are declining far more rapidly than are the populations of nonamphibian species whose tissues and eggs have more natural protection from uv-b.

(c) atmospheric ozone has been significantly depleted above all the areas of the world in which amphibian populations are declining.

(d) the natural habitat of amphibians has not be smaller over the past century.

(e) amphibian populations have declined continuously for the last 50 years.
