Ethicist: Studies have documented the capacity of placebos to reduce pain in patients who believe that they are receiving beneficial drugs. Some doctors say that they administer placebos because medically effective treatment reinforced by the placebo effect sometimes helps patients recover faster than good treatment alone.

But administering placebos is nonetheless ethically questionable, for even if a placebo benefits a patient, a doctor might, for example, have prescribed it just to give the patient satisfaction that something was being done.

The ethicist's argument depends on which one of the following assumptions?

  1. A patient's psychological satisfaction is not a consideration in administering medical treatment.
  2. The motivation for administering a placebo can be relevant to the ethical justification for doing so.
  3. Medical treatment that relies on the placebo effect alone is ethically indefensible.
  4. The pain relief produced by the placebo effect justifies the deception involved in administering a placebo.
  5. Administering a placebo is not ethically justified if that treatment is not prescribed by a doctor.

Answer(s): B

Explanation:

The author comes down squarely on the ethical dubiousness of administering placebos on the grounds that, beneficial or not, the placebo may have been prescribed merely in order to placate the patient. For that evidence to lead to the conclusion, the author must be assuming that the ethics of placebo administration has something to do with the motivation behind prescribing placebos.
If [The motivation for administering...] were false, the author could still question the ethics of prescribing placebos, but not on the grounds of a doctor's motives for doing so.



After the United Nations Security Council authorized military intervention by a coalition of armed forces intended to halt civil strife in a certain country, the parliament of one UN member nation passed a resolution condemning its own prime minister for promising to commit military personnel to the action. A parliamentary leader insisted that the overwhelming vote for the resolution did not imply the parliament's opposition to the anticipated intervention; on the contrary, most members of parliament supported the UN plan.

Which one of the following, if true, most helps to resolve the apparent discrepancy presented above?

  1. The UN Security Council cannot legally commit the military of a member nation to armed intervention in other countries.
  2. In the parliamentary leader's nation, it is the constitutional prerogative of the parliament, not of the prime minister, to initiate foreign military action.
  3. The parliament would be responsible for providing the funding necessary in order to contribute military personnel to the UN intervention.
  4. The public would not support the military action unless it was known that the parliament supported the action.
  5. Members of the parliament traditionally are more closely attuned to public sentiment, especially with regard to military action, than are prime ministers.

Answer(s): B

Explanation:

The paradox or "discrepancy" is that a country's parliament was all for the UN decision to send in an international peacekeeping force, yet censured its own prime minister for promising troops to that force. Option [In the parliamentary leader's nation...] resolves the dilemma by implying that it wasn't the promise of troops that irked the parliament, but rather the unconstitutional involvement of the prime minister in that promise. It's not at all paradoxical, in light of [In the parliamentary leader's nation...], for a parliament to say "We're in favor of sending troops, but we not you, prime minister, are supposed to make that judgment."



People who are good at playing the game Drackedary are invariably skilled with their hands. Mary is a very competent watchmaker. Therefore, Mary would make a good Drackedary player.

The flawed pattern of reasoning in the argument above is most similar to that in which one of the following?

  1. People with long legs make good runners. Everyone in Daryl's family has long legs. Therefore, Daryl would make a good runner.
  2. People who write for a living invariably enjoy reading. Julie has been a published novelist for many years.
    Therefore, Julie enjoys reading.
  3. All race car drivers have good reflexes. Chris is a champion table tennis player. Therefore, Chris would make a good race car driver.
  4. The role of Santa Claus in a shopping mall is often played by an experienced actor. Erwin has played Santa Claus in shopping malls for years. Therefore, Erwin must be an experienced actor.
  5. Any good skier can learn to ice-skate eventually. Erica is a world-class skier. Therefore, Erica could learn to ice-skate in a day or two.

Answer(s): C

Explanation:

The stimulus conclusion "X would make a good Y" is only paralleled by options [People with long legs make good...] and [All race car drivers have good reflexes...]: the conclusions in [People who write for a living invariably] and [The role of Santa Claus in...] are flat-out assertions of fact, and option [Any good skier can learn to...] is is a vague speculation. Only [All race car drivers have good reflexes...] parallels the structure that we can express algebraically as: All X are Y. A particular individual is Z; therefore, that individual would make a good Y.

The Daily Gazette

If The Daily Gazette denies each of the following subscriber's requests, each of the denials could be justified solely on the basis of the policy stated above EXCEPT:

  1. Mr. Rathanan did not send in his advance payment two weeks ago; he states that his inaction was intended as cancellation and requests that he not be charged for the past two weeks of delivery of The Daily Gazette.
  2. Dr. Broder called The Daily Gazette Monday morning to report that her Sunday edition had not been delivered; she requests credit instead of the offered replacement copy.
  3. The Daily Gazette was delivered to Ms. Herrera during her one-week vacation even though she called on a Wednesday to stop delivery the following Monday for the entire week; she requests credit for the full week's delivery.
  4. Although Ms. Jackson telephoned The Daily Gazette at the beginning of June requesting that her subscription be canceled on June 30, delivery was continued until July 3 when she called to complain; she requests that she not be charged for the papers delivered in July.
  5. Ms. Silverman was out of town on Sunday and Monday and when she returned on Tuesday she found that her Sunday edition had not been delivered; she called The Daily Gazette on Tuesday afternoon requesting credit for the undelivered copy.

Answer(s): C



Expert witness: Ten times, and in controlled circumstances, a single drop of the defendant's blood was allowed to fall onto the fabric. And in all ten cases, the stained area was much less than the expected 9.5 cm2. In fact, the stained area was always between 4.5 and 4.8 cm2.1 conclude that a single drop of the defendant's blood stains much less than 9.5 cm2 of the fabric.

Which one of the following, if true, most undermines the value of the evidence for the expert witness's conclusion?

  1. If similar results had been found after 100 test drops of the defendant's blood, the evidence would be even stronger.
  2. Expert witnesses have sometimes been known to fudge their data to accord with the prosecution's case.
  3. In an eleventh test drop of the defendant's blood, the area stained was also less than 9.5cm2--this time staining 9.3 cm".
  4. Another person's blood was substituted, and in otherwise identical circumstances, stained between 9.8 and 10.6 cm2of the fabric.
  5. Not all expert witnesses are the authorities in their fields that they claim to be.

Answer(s): C

Explanation:

The task here is to weaken the conclusion that a single drop of this defendant's blood stains "much less than 9.5 square cm of the fabric." The evidence consists of 10 samples, each of which covered about of that area.
But if an 11th sample covered almost the entire 9.5 square cm, as option [In an eleventh test drop of...] points out, then the witness' certainty about a droplet's being sure to stain "much less than 9.5" must be reduced to almost zero.
