instruction:
Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
question:
original question: Which tv character has the final tv appearance in the episode named [Unending]?
answer: thor
answer type: TV Character.
auxiliary information: "Unending" is the season finale of the tenth season and series finale of the science fiction television series Stargate SG-1, and the show's two-hundred sixteenth episode overall. Written and directed by Robert C. Cooper, the episode originally premiered in the United Kingdom on Sky One on March 13, 2007, and in the United States on June 22, 2007 on the Sci Fi Channel. The episode attracted approximately 2.2 million viewers on its American broadcast, a ratings success for the Sci Fi Channel. The episode begins with the mass suicide of the Asgard race, who try to preserve their legacy by giving all of their accumulated knowledge and technology to the SG-1 team and the crew of the Earth ship Odyssey. When the ship is attacked by Ori warships, Lieutenant-Colonel Samantha Carter creates a time dilation field that speeds up time within the ship, and it takes fifty years until a defense against the Ori weapons can be found.

question:
original question: How many medical treatments are being tested by [Physicians' Health Study]?
answer: 2
answer type: Medical Treatment.
auxiliary information: To assess the effect on cardiovascular mortality of alternate-day consumption of 325 milligrams of aspirin and, secondarily, the effect on cancer incidence of alternate-day consumption of 50 milligrams of beta-carotene.BACKGROUND: Thrombosis plays a major role in the late stages of coronary occlusion. Platelet aggregation is a large component in the formation of arterial thrombi. In pharmacologic studies, aspirin has been shown to inhibit platelet aggregation and, therefore, might be expected to prevent coronary occlusion. These effects are apparent in the dose range of l00-l000 mg/day, and may be most evident at l60 milligrams daily. Higher doses seem to be no more effective in either inhibition of platelet agreeability or prolonged bleeding time. Although an early case-control study by Jick and Miettinen showed a large benefit, most observational studies had shown a cardiovascular benefit of about 20 percent. Conclusive data could only result from a randomized trial with a large sample size. DESIGN NARRATIVE: Randomized, double-blind, fixed sample. Participants were randomized into one of four treatment groups: one 325 milligram aspirin tablet every other day, alternating with one 30 milligram capsule of beta-carotene; one aspirin every other day, alternating with one capsule of beta-carotene placebo; one aspirin placebo tablet every other day, alternating with one capsule of beta-carotene; and one aspirin placebo tablet every other day, alternating with one capsule of beta-carotene placebo. Major endpoints for the cardiovascular component of the study were cardiovascular mortality, total mortality, and coronary events.
answer:
How many different medical treatments are being tested by [Physicians' Health Study]?

question:
original question: Which composition has the subjects of [Mother]?
answer: mother
answer type: Composition.
auxiliary information: Mothers are women who inhabit or perform the role of bearing some relation to their children, who may or may not be their biological offspring. Thus, dependent on the context, women can be considered mothers by virtue of having given birth, by raising their child, supplying their ovum for fertilization, or some combination thereof. Such conditions provide a way of delineating the concept of motherhood, or the state of being a mother. Women who meet the third and first categories usually fall under the terms 'birth mother' or 'biological mother', regardless of whether the individual in question goes on to parent their child. Accordingly, a woman who meets only the second condition may be considered an adoptive mother, and those who meet only the third a surrogacy mother. The above concepts defining the role of mother are neither exhaustive nor universal, as any definition of 'mother' may differ based on how social, cultural, and religious roles are defined. The parallel conditions and terms for males: those who are fathers do not, by definition, take up the role of fatherhood. It should also be noted that mother and fatherhood are not limited to those who are or have parented.
