In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: The purpose of this study was to examine the effectiveness of ankle bracing and taping in preventing recurrencess of ankle sprains, specifically in female athletes.', "Varsity soccer players' medical records over a five-year period were retrospectively reviewed at a Division III women's college. Data were extracted regarding any history of ankle sprain(s), type of intervention used as prophylaxis after the ankle sprain, number of exposures, and any incidence of recurrence.", 'All collegiate varsity soccer players who had suffered a previous sprain to either one or both ankles (38 players) were identified as subjects.', 'Each previously injured ankle (n = 56) was considered as a case for the analysis. Ankles that had a previous sprain received one of four interventions: 1) a canvas, laced ankle brace (n = 19), 2) taping (n = 12), 3) a combination of taping and ankle bracing (n = 8), or 4) no treatment (n = 17).', 'The four intervention groups had a total of 1717 practice exposures and 650 competitive game exposures; exposures did not differ among the 4 groups. Ankle sprain recurrence frequency was 0%, 25%, 25%, and 35% for the braced, taped, combination, and untreated groups, respectively. The recurrence incidence for the braced group was significantly lower than that of the other three groups. The ankle sprain recurrence frequency did not differ among the taped, combination, and no treatment groups.\Question: Does ankle brace effectively reduce recurrence of ankle sprains in female soccer players?

Output: We suggest that prophylactic ankle bracing is effective in reducing the incidence of ankle sprains in female soccer players with a previous history of ankle sprains.


Input: Consider Input: Context: To investigate the existence condition of hepatitis B surface antigen(HBsAg) termination codon bias.', 'A total of 174 reference sequences of all kinds of Hepatitis B virus(HBV) genotypes were chosen from GenBank, and compared by BioEdit. Then secondary structure of RNA was constructed and analyzed together.', '(1) There were two types of HBsAg termination codon: TAA and TGA in 174 reference sequences. TAA was in 124 cases (71.26%); and TGA in 50 cases (28.74%). (2) There was codon bias selection in HBsAg termination codon, and it could affect the secondary structure of RNA and amino acid sequence encoding protein.\Question: Does [ Hepatitis B surface antigen terminate codon bias selection ]?

Output: HBsAg termination codon bias exists and may be related to RNA structure and the conservation of protein function in the evolutionary progress.


Input: Consider Input: Context: Despite efficacious treatment, alcohol use disorders contribute significantly to the disability burden. Although wider dissemination of evidence-based health care may impact on the population burden, the affordability of this strategy is unknown. This article compares the cost-effectiveness of current treatment for alcohol use disorders with the cost-effectiveness of optimal treatment, a hypothetical treatment scenario that has been informed by evidence-based practice to determine the affordability of such an approach.', 'This study calculated the cost-effectiveness in the Australian population of evidence-based health care for alcohol harmful use and alcohol dependence, as defined by the International Classification of Diseases, Injuries, and Causes of Death, 10th Revision. Outcome was calculated as years lived with disability (YLD) averted. Data from the Australian National Survey of Mental Health and Wellbeing, in conjunction with published meta-analyses and expert reviews, were used to estimate 1-year costs (1997-98 Australian dollars) and YLD averted by current health care services as well as costs and outcomes for an optimal strategy of evidence-based health care.', 'Of those currently seeking treatment, approximately 45% of those with alcohol harmful use and 58% of those with alcohol dependence receive an evidence-based intervention. The cost of this care was estimated at 73 million dollars, resulting in a cost per YLD averted of 96,813 dollars for harmful use of alcohol and 98,095 dollars for alcohol dependence. Under optimal care for harmful use, costs declined and health gains doubled, substantially reducing the cost per YLD averted to 8861 dollars. For dependence, costs doubled, but optimal treatment resulted in increased health gains, reducing the cost per YLD to 57,542 dollars.\Question: Is evidence-based care for alcohol use disorders affordable?


Output: Evidence-based care for alcohol use disorders would produce greater population health gain at an increased cost for alcohol dependence but at a reduced cost for harmful use of alcohol. For both disorders, there are substantial increases in cost-effectiveness.
