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.

Example Input: Context: No formal assessment of life expectancy in women with BRCA1 and BRCA2 mutations in these genes has been reported previously. We have evaluated life expectancy using actuarial analysis and assessed the effect of breast and ovarian cancers on premature death in >1,000 BRCA1/2 carriers.', 'Families with pathogenic mutations in BRCA1 and BRCA2 have been ascertained in a 10-million population region of United Kingdom since 1996. Mutation carriers and their first-degree relatives were used in an analysis of breast and ovarian cancer incidence and mortality as well as to derive and compare an actuarial assessment of life expectancy.', 'Six hundred twelve BRCA1 and 482 BRCA2 female mutation carriers were identified from 482 families. Life expectancy was significantly reduced for BRCA1 carriers compared with BRCA2 (P = 0.0002). This effect was attributable to an increased death rate from ovarian cancer (P = 0.04). Kaplan-Meier analysis revealed a better long-term survival from early-stage ovarian cancer in BRCA2 carriers but no significant differences in deaths from breast cancer or from women presenting with late-stage ovarian cancer. There was no other major contributing cause to death other than breast/ovarian cancer in BRCA1/2 female carriers.\Question: Is better life expectancy in women with BRCA2 compared with BRCA1 mutations attributable to lower frequency and later onset of ovarian cancer?
Example Output: Interventions to reduce ovarian cancer incidence are likely to have a greater effect on life expectancy in BRCA1 compared with BRCA2 carriers.

Example Input: Context: rs1333049 polymorphism on chromosome 9p21 has been shown to affect susceptibility to coronary artery disease (CAD) in Caucasians. This study examined the association of rs1333049 with myocardial infarction (MI), angiographic severity of CAD and clinical outcome after a first acute MI in Han Chinese.', 'rs1333049 polymorphism was genotyped in 520 patients with a first acute MI and in 560 controls. The number of angiographically documented diseased coronary arteries (luminal diameter stenosis > or = 50%), echocardiographic left ventricular ejection fraction (LVEF), and major adverse cardiac events (MACE) during follow-up (mean, 29+/-15 months) were recorded.', 'Patients with MI had higher frequencies of the CC genotype (30.0% vs. 20.7%) or C allele (55.5% vs. 46.2%) compared with controls (all p<0.01). rs1333049 polymorphism was strongly associated with MI [odds ratio (OR) 1.48, 95% confidence interval (CI) 1.22-1.79] after adjusting for traditional risk factors. Although longer hospitalization stay was observed in patients with the rs1333049-C allele, this polymorphism was not related to angiographic severity of CAD, LVEF, and occurrence of MACE after MI.\Question: Is chromosome 9p21 polymorphism associated with myocardial infarction but not with clinical outcome in Han Chinese?
Example Output: This study demonstrates an association of rs1333049 polymorphism locus on chromosome 9p21 with risk for MI, but not with post-MI prognosis in Han Chinese.

Example Input: Context: To compare the Tardieu Scale as a clinical measure of spasticity after stroke with the Ashworth Scale.', 'Cross-sectional study.', 'Sixteen people, living in the community three years after their stroke.', 'The Ashworth Scale and Tardieu Scale as well as laboratory measures of spasticity (stretch-induced electromyographic (EMG) activity) and contracture (maximum passive joint excursion) were collected from the affected elbow flexors and extensors and ankle plantarflexors and dorsiflexors by three examiners who were blinded to the results of the other measures.', 'The percentage exact agreement (PEA) between the Tardieu Scale and a laboratory measure of spasticity was 100% for both the elbow flexors and ankle plantarflexors. This was significantly (P= 0.02) greater than the PEA of 63% for both muscles between the Ashworth Scale and the same laboratory measure of spasticity. For contracture, the PEA between the Tardieu Scale and a laboratory measure was 94% for both the elbow flexors and the ankle plantarflexors. Pearson correlation coefficients between the Tardieu Scale and laboratory measures of spasticity were 0.86 for the elbow flexors and 0.62 for the ankle plantarflexors and between the Tardieu Scale and laboratory measures of contracture were 0.89 for the elbow flexors and 0.84 for the ankle plantarflexors.\Question: Does the Tardieu Scale differentiate contracture from spasticity whereas the Ashworth Scale is confounded by it?
Example Output:
In all cases that spasticity was overestimated by the Ashworth Scale, participants had a contracture. These findings suggest that the Tardieu Scale differentiates spasticity from contracture whereas the Ashworth Scale is confounded by it.
