The fewer restrictions there are on the advertising of legal services, the more lawyers there are who advertise their services, and the lawyers who advertise a specific service usually charge less for that service than the lawyers who do not advertise. Therefore, if the state removes any of its current restrictions, such as the one against advertisements that do not specify fee arrangements, overall consumer legal costs will be lower than if the state retains its current restrictions.

If the statements above are true, which of the following must be true?
(A) Some lawyers who now advertise will charge more for specific services if they do not have to specify fee arrangements in the advertisements.
(B) More consumers will use legal services if there are fewer restrictions on the advertising of legal services.
(C) If the restriction against advertisements that do not specify fee arrangements is removed, more lawyers will advertise their services.
(D) If more lawyers advertise lower prices for specific services, some lawyers who do not advertise will also charge less than they currently charge for those services.
(E) If the only restrictions on the advertising of legal services were those that apply to every type of advertising, most lawyers would advertise their services.

Above question is discussed here: the-fewer-restrictions-there-are-on-the-advertising-og10-151118.html

When there is less rainfall than normal, the water level of Australian rivers falls and the rivers fl ow more slowly. Because algae whose habitat is river water grow best in slow-moving water, the amount of algae per unit of water generally increases when there has been little rain. By contrast, however, following a period of extreme drought, algae levels are low even in very slow-moving river water.

Which of the following, if true, does most to explain the contrast described above?
(A) During periods of extreme drought, the populations of some of the species that feed on algae tend to fall.
(B) The more slowly water moves, the more conducive its temperature is to the growth of algae.
(C) When algae populations reach very high levels, conditions within the river can become toxic for some of the other species that normally live there.
(D) Australian rivers dry up completely for short intervals in periods of extreme drought.
(E) Except during periods of extreme drought, algae levels tend to be higher in rivers in which the flow has been controlled by damming than in rivers that flow freely.

Although parapsychology is often considered a pseudoscience, it is in fact a genuine scientific enterprise, for it uses scientific methods such as controlled experiments and statistical tests of clearly stated hypotheses to examine the questions it raises.

The conclusion above is properly drawn if which of the following is assumed?

(A) If a field of study can conclusively answer the questions it raises, then it is a genuine science.
(B) Since parapsychology uses scientific methods, it will produce credible results.
(C) Any enterprise that does not use controlled experiments and statistical tests is not genuine science.
(D) Any field of study that employs scientific methods is a genuine scientific enterprise.
(E) Since parapsychology raises clearly statable questions, they can be tested in controlled experiments.

The fewer restrictions there are on the advertising of legal services, the more lawyers there are who advertise their services, and the lawyers who
advertise a specific service usually charge less for that service than the lawyers who do not advertise. Therefore, if the state removes any of its current restrictions, such as the one against advertisements that do not specify fee arrangements, overall consumer legal costs will be lower than if the state retains its current restrictions.

If the statements above are true, which of the following must be true?
(A) Some lawyers who now advertise will charge more for specific services if they do not have to specify fee arrangements in the advertisements.
(B) More consumers will use legal services if there are fewer restrictions on the advertising of legal services.
(C) If the restriction against advertisements that do not specify fee arrangements is removed, more lawyers will advertise their services.
(D) If more lawyers advertise lower prices for specific services, some lawyers who do not advertise will also charge less than they currently charge for those services.
(E) If the only restrictions on the advertising of legal services were those that apply to every type of advertising, most lawyers would advertise their services.

The argument is , any restriction removed=> more lawyers will advertise => such lawyers charge less

Choice C which is , a restriction removed => more lawyers will advertise

which is in line with the argument. None of the other choices are.

When there is less rainfall than normal, the water level of Australian rivers falls and the rivers fl ow more slowly. Because algae whose habitat is river water grow best in slow-moving water, the amount of algae per unit of water generally increases when there has been little rain. By contrast, however, following a period of extreme drought, algae levels are low even in very slow-moving river water.

Which of the following, if true, does most to explain the contrast described above?
(A) During periods of extreme drought, the populations of some of the species that feed on algae tend to fall.
(B) The more slowly water moves, the more conducive its temperature is to the growth of algae.
(C) When algae populations reach very high levels, conditions within the river can become toxic for some of the other species that normally live
there.
(D) Australian rivers dry up completely for short intervals in periods of extreme drought.
(E) Except during periods of extreme drought, algae levels tend to be higher in rivers in which the flow has been controlled by damming than in
rivers that flow freely.

Since the habitat of the algae is river water, when the rivers completely dry up during extreme drought all the algae die. So after extreme drought, algae levels are naturally low. Therefore choice D. None of the other choices explain why after extreme drought algae levels are low

Although parapsychology is often considered a pseudoscience, it is in fact a genuine scientific enterprise, for it uses scientific methods such as controlled experiments and statistical tests of clearly stated hypotheses to examine the questions it raises.

The conclusion above is properly drawn if which of the following is assumed?

(A) If a field of study can conclusively answer the questions it raises, then it is a genuine science.
(B) Since parapsychology uses scientific methods, it will produce credible results.
(C) Any enterprise that does not use controlled experiments and statistical tests is not genuine science.
(D) Any field of study that employs scientific methods is a genuine scientific enterprise.
(E) Since parapsychology raises clearly statable questions, they can be tested in controlled experiments.

The argument is , parapsychology uses scientific methods => it is a genuine scientific enterprise

From the above, the assumption stated in D easily follows.
