Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Example Input: Context: Chronic HIV/HCV co-infection carries increased risk of cirrhosis, hepatocellular carcinoma, and death. Due to anti-inflammatory properties, HMG co-A inhibitors (statins) may be useful adjunctive therapy to reduce liver disease progression.', 'Clinical information was extracted from the Veterans Affairs HIV and HCV Clinical Case Registries (1999 - 2010). HIV-related variables included combination anti-retroviral therapy (cART) era of diagnosis, CD4 cell count, and percent time with undetectable HIV viral load. Metabolic variables included diabetes, low-HDL, and hypertension. Statin use was measured as percent time with active prescription (time-updated throughout the follow-up period). Cox proportional hazards analysis was used to determine risk factors for cirrhosis (ICD-9 or APRI>2) overall and in groups stratified by alanine aminotransferase (ALT) level above and below 40IU/L.', 'The cohort included 5985HIV/HCV co-infected veterans. The majority was black race, and the mean age at index date was 45 years. Statin use was significantly protective of cirrhosis for patients with ALT 40IU/L; for every 30% increase in time on statin, there was a 32% decreased risk of developing cirrhosis (HR 0.68, 95% CI 0.47 -0.98). Diabetes and low-HDL were significantly associated with cirrhosis in patients with ALT > 40IU/L (HR 1.15, p<0.04 and HR 1.3, p<0.0001).
Answer: Statin drug use is beneficial in mitigating the risk of liver disease progression for HIV/HCV co-infected patients without advanced liver disease. Low-HDL and diabetes in co-infected patients with abnormal ALT have greater risk of cirrhosis development.
Example Output: Do statin drugs decrease progression to cirrhosis in HIV/HCV co-infected individuals?

Example Input: Context: To determine the prevalence of fathers' attendance at pretest cancer genetic counseling sessions with mothers undergoing BRCA1/2 genetic testing for hereditary breast/ovarian cancer (HBOC) risk, and to identify psychosocial and other correlates of fathers' attendance.", 'One hundred and twenty-one fathers of minor-age children who were spouses/partners of women (mothers) undergoing such counseling and testing were recruited, completed a behavioral self-report survey, and provided data about their sociodemographic backgrounds, father-child cancer communication histories, parenting relationship quality, and information-seeking and perceived knowledge.', 'A total of 27.3% of fathers attended pretest cancer genetic counseling with mothers. Compared to fathers who did not attend pretest cancer genetic counseling, those who did had stronger parenting alliances with mothers, were more likely to have sought out information about BRCA1/2 testing, and felt more informed about testing. In an adjusted logistic regression model of session attendance, the strength of the parenting alliance was associated with a 6% increase in the likelihood of attending genetic counseling (odds ratio [OR]=1.06, 95% confidence interval [CI]=1.01, 1.12, p<.05) and greater perceived knowledge about BRCA1/2 testing was associated with a four-fold increase in the likelihood of session attendance (OR=4.03, CI=1.77, 9.37, p<.001).
Answer: One in three fathers attend pretest cancer genetic counseling with mothers undergoing BRCA1/2 testing; those who do have closer parenting relationships and are more informed about BRCA1/2 testing.
Example Output: Does prevalence and correlate of mothers and fathers attending pretest cancer genetic counseling together?

Example Input: Context: FAAH degrades endocannabinoids and fatty acid amides. FAAH inhibition reduces micturition frequency and counteracts bladder overactivity in rats. We studied the effects of the peripherally active selective FAAH inhibitor URB937, and the CB1 and CB2 receptor antagonists rimonabant and SR144528, respectively, on single unit afferent activity of primary bladder afferents in rats.', 'Female Sprague Dawley®️ rats were anesthetized. Single unit afferent activity of A or C-fibers from the L6 dorsal roots was recorded during bladder filling before and after URB937 administration with or without rimonabant or SR144528. Drugs (1 mg/kg) were given intravenously. FAAH, CB1 and CB2 expression, and expression of the sensory marker CGRP inthe L6 dorsal root ganglion were compared by immunofluorescence.', 'A total of 102 single afferent fibers (48 A and 54 C-fibers) were isolated from 57 rats. URB937 decreased single unit afferent activity of C-fibers to a mean SEM of 78% 9% and of A-fibers to a mean of 67% 7% while increasing bladder compliance to a mean of 116% 3%. The effects of URB937 on single unit afferent activity and bladder compliance were counteracted by rimonabant or SR144528. Rimonabant increased single unit afferent activity ofeach fiber type but SR144528 affected only A-fiber activity. CGRP positive L6dorsal root ganglion neurons showed strong FAAH, CB1 and CB2 staining.
Answer: To our knowledge we report for the first time that inhibiting peripheral FAAH depresses the A and C-fiber activity of primary bladder afferents via CB1 and CB2 receptors. CB antagonists alone exerted facilitatory effects on single unit afferent activity during bladder filling in rats. The endocannabinoid system may be involved in physiological control of micturition as regulators of afferent signals.
Example Output:
Does inhibition of peripheral FAAH depress activities of bladder mechanosensitive nerve fibers of the rat?
