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: To assess the role of whole-body computed tomography (CT) for determining morphological suitability before multiorgan retrieval (MOR) in brain dead patients.', 'Fifty-one clinically brain dead patients (21 women, 30 men; mean age 61 year±15) were included in this prospective, single center study. All patients had CT angiography of the brain and whole-body CT examination. CT images were evaluated for the presence of morphological abnormalities of lungs, liver and other abdominal organs and presence of vascular anatomical variants. The results of CT examinations were compared to intraoperative findings observed during organ harvesting and/or the results of histopathological analysis of biopsy specimens. The impact of whole-body CT examination on the harvesting process was evaluated.', 'Ninety-five percent of vascular anatomical variants that were found intraoperatively were depicted on CT. CT density measurements predicted surgical finding of steatosis in 80% of patients. Whole-body CT changed the MOR strategy in 21/51 patients (41%) including 3 MOR cancellations and 8 grafts refusals, whereas organ harvesting was continued in 10 patients after histopathological analysis was performed.
Answer: Selection of potential graft donors using whole-body CT is reliable and improves graft selection during MOR.
Example Output: Is simultaneous CT angiography and whole-body CT an effective imaging approach before multiorgan retrieval?

Example Input: Context: Contralateral groin exploration in children with unilateral inguinal hernia is still controversial, particularly in infants. The patency rate of processus vaginalis is highest in infants but there are few data on the subsequent risk of contralateral hernia development in infants. In this retrospective study, we aimed to find out the incidence of contralateral inguinal hernia following unilateral inguinal herniotomy in infants aged less than one year.', 'All infants who underwent a unilateral Inguinal herniotomy between January 1990 and December 1998 were studied retrospectively. Infants with bilateral hernia (n = 7) were excluded from the study.', 'One hundred and one infants (93 boys and 8 girls) were studied. Median age at operation was 23 (range 2-52) weeks. The herniotomy was right-sided in 75% of the infants. Follow-up ranged from three and a half years to 11 years. A contralateral hernia developed in nine infants (9.0%). One of the initial hernias was incarcerated. Median time from operation to occurrence of contralateral hernia was 18 (range 2-60) months. None of the contralateral hernia was incarcerated. Age, sex, incarceration and side of initial hernia did not influence the development of contralateral hernia.
Answer: The low incidence and benign nature of contralateral hernia development in infants undergoing a unilateral inguinal herniotomy does not justify routine contralateral groin exploration.
Example Output: Is contralateral groin exploration justified in infants with a unilateral inguinal hernia?

Example Input: Context: Peroxisome proliferator-activated receptor (PPAR)-β/δ is a transcription factor that belongs to the nuclear hormone receptor family. There is little information about the effects of the immediate administration of specific ligands of PPAR-β/δ (GW0742) in animal models of acute ischemic stroke. Using a rat model of middle cerebral ischemia occlusion (MCAO) in\xa0vivo, we have investigated the effect of pretreatment with GW0742 before MCAO.', 'The neuroprotective effect of GW0742 against acute ischemic stroke was evaluated by the neurologic deficit score (NDS), dry-wet weight, and 2,3,5-triphenyltetrazolium chloride staining. The levels of interleukin (IL)-1β, nuclear factor (NF)-κB, and tumor necrosis factor (TNF)-α were detected by an enzyme-linked immunosorbent assay. The expressions of inducible nitric oxide synthase (iNOS), Bax, and Bcl-2 were detected by Western blot. The apoptotic cells were counted by in situ terminal deoxyribonucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling assay.', 'The pretreatment with GW0742 significantly increased the expression of Bcl-2, and significantly decreased in the volume of infarction, NDS, edema, expressions of IL-1β, NF-κB, TNFα, and Bax, contents of iNOS and the apoptotic cells in infarct cerebral hemisphere compared with rats in the vehicle group at 24\xa0hours after MCAO.
Answer: The study suggests the neuroprotective effect of the PPAR-β/δ ligand GW0742 in acute ischemic stroke by a mechanism that may involve its anti-inflammatory and antiapoptotic action.
Example Output:
Does activation of peroxisome proliferator-activated receptor β/δ attenuate acute ischemic stroke on middle cerebral ischemia occlusion in rats?
