Given a passage, 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: This study addresses the potential utility of preoperative functional imaging with magnetoencephalography (MEG) for the selection of glioma patients who are likely to benefit from resective surgical treatment regarding postoperative morbidity.', 'One hundred and nineteen patients with gliomas adjacent to sensorimotor, visual and speech related brain areas were investigated preoperatively with a MAGNES II biomagnetometer. In each patient the pre-surgical evaluation was focussed on the visual, sensorimotor cortex and/or of the speech related brain areas. A grading system was then used according to the distance of the MEG activation sources to the nearest tumour border to determine the further treatment. The therapeutic options consisted in conservative treatment, stereotactic biopsy and/or a radiation and chemotherapy, substantial cytoreduction and the gross total removal of the lesion.', 'From 119 investigated patients, 55 patients (46.2%) were not considered for surgery due to tumour invasion to functional cortex. Sixty four patients (53.8%) were chosen for resective surgery. In the surgical group only four patients (6.2%) suffered from neurological deterioration.
Example Output: Does magnetic source imaging support clinical decision making in glioma patients?

Example Input: Pulmonary hypertension (PH) is prognosti- cally important in chronic obstructive pulmonary disease (COPD). Since PH only weakly correlates with hypoxemia, other factors must play a role.', 'To investigate whether polymorphisms of the serotonin transporter (5HTT), serotonin-2a receptor (5HTR2a) and endothelial nitric oxide synthetase (eNOS) are related to PH in COPD.', 'In 59 COPD patients who underwent right heart catheterization, 6-min walking distance, NYHA functional class, pulmonary function tests, blood gases and 5HTT, 5HTR2a and eNOS (4ab and T298C) polymorphisms were determined.', 'Forty-nine COPD patients in NYHA functional class III-IV were included. Ten were excluded due to comorbid causes of PH (mainly chronic thromboembolic). PH (mPAP > or =25 mm Hg) was present in 55% and usually mild, but out of proportion (mPAP > or =40 mm Hg) in 12%. Patients with PH had significantly higher frequencies of the 5HTT-L-allele (52%) compared to individuals without PH (36%), and LL homozygote patients had more severe PH. In patients with out-of-proportion PH, the L-allelic frequency was even 75%. We found no association of 5HTR2a and eNOS polymorphism with PH in COPD.
Example Output: Are genetic polymorphisms of the serotonin transporter , but not the 2a receptor or nitric oxide synthetase , associated with pulmonary hypertension in chronic obstructive pulmonary disease?

Example Input: Violence and safety exposures, primarily in the form of intimate partner violence (IPV) exposures, have been associated with increased healthcare utilization in women and variable associations with preventive services. It remains unknown, however, if broader measures of violence and safety exposures are associated with preventive healthcare utilization.', 'Data from the 2004 The Philadelphia Health Management Corporation survey were used to compare self-reported utilization of preventive healthcare services for participants who did and did not report exposures to violence or have safety concerns during the past year, using novel but nonvalidated measures of violence and safety concerns. The sample included women aged 18-96 years who reported having a usual source of care. Measures of preventive healthcare utilization included timing of last mammogram, cervical cytology, breast examination, blood cholesterol testing, blood pressure measurement, and screening for colon cancer.', 'The survey had an American Association for Public Opinion Research response rate of 30.4%. Of the 6285 women surveyed who reported having a usual source of care, 456 (7.3%) reported either an exposure to violence or safety concerns, and 5821 did not. Using logistic regression models, women aged 18-65 years who reported safety concerns were less likely to report having cervical cancer testing in the past 12 months (OR 0.68, 95% CI 0.49-0.94). Women > or =40 years who reported safety concerns in the last year were less likely to report having clinical breast examinations (OR 0.63, 95% CI 0.43-0.93) or mammography (OR 0.57, 95% CI 0.39-0.83). Physical violence exposure was not significantly associated with preventive healthcare utilization.
Example Output:
Do women with safety concerns report fewer gender-specific preventive healthcare services?
