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.

[EX Q]: Precise long-term assessment of movement and physical function following Achilles tendon rupture is required for the development and evaluation of treatment, including different regimens of physical therapy.', 'To assess intermediate-term (<10 years by conventional thinking) objective measures of physical function following Achilles tendon rupture treated nonsurgically and to compare these with self-reported measures of physical function.', 'Cross-sectional study; Level of evidence, 3.', 'Two to 5 years after Achilles tendon rupture, 9 women and 43 men (mean age, 49.2 years; range, 26-68 years) were assessed by physical examination, performance of 1-legged jumps, and 3-dimensional gait analysis (including calculation of muscle work). Self-reported scores for foot function (Achilles tendon rupture score) and level of physical activity were collected. Twenty age- and sex-matched controls were assessed in the same manner.', 'Physical examination of patients with the knee extended revealed 11.1 of dorsiflexion on the injured side and 9.2 on the uninjured side (P = .020), indicating gastrocnemius muscle lengthening. The 1-legged jump distance was shorter on the injured side (89.5 vs 96.2 cm; P < .001). Gait analysis showed higher peak dorsiflexion (14.3 vs 13.3; P = .016) and lower concentric (positive) plantar flexor work (16.6 vs 19.9 J/kg; P = .001) in the ankle on the uninjured side. At the same time, eccentric (negative) dorsiflexor work was higher on the injured side (13.2 vs 11.9 J/kg; P = .010). Self-perceived foot function and physical activity were lower in patients than in healthy controls (mean Achilles tendon rupture score, 78.6 and 99.8, respectively).

[EX Q]: It is a matter of debate whether or not ordinary heading of the ball in soccer causes injury to brain tissue.', 'To analyse concentrations of the biochemical markers of brain tissue damage S-100B and neurone specific enolase (NSE) in serum of female elite soccer players in association with a competitive game.', 'Venous blood samples were obtained from 44 female soccer players before and after a competitive game for analysis. The number of headers and trauma events (falls, collisions, etc) was assessed from videotape recordings for each player.', 'Concentrations of both brain damage markers were increased after the game (S-100B, 0.18 (0.11) v 0.11 (0.05) microg/l (p = 0.000); NSE, 10.14 (1.74) v 9.05 (1.59) microg/l (p = 0.001)). There was a significant correlation between changes in S-100B concentrations and both the number of headers (r = 0.430, p = 0.004) and the number of other trauma events (r = 0.517, p < 0.001).

[EX Q]: While the incidence of inflammatory bowel disease (IBD) among African-Americans (AAs) is increasing, there is limited understanding of phenotypic differences and outcomes by race.', 'To describe disease characteristics of AA patients compared to Caucasian (Ca) patients in a tertiary care population.', "We performed a cross-sectional review of the IBD registry at the University of Chicago from January 2008 to January 2013. Data regarding race, phenotype, disease onset, disease duration, medical therapy, and surgical treatment were abstracted from the database, then compared via Pearson's chi-square analysis, Kruskal-Wallis analysis, and logistic regression with a significance level of p < 0.05.", "A total of 1,235 patients with Crohn's disease (CD) and 541 patients with ulcerative colitis (UC) included 108 AA CD patients and 28 AA UC patients. AA CD patients had an increased rate of IBD-related arthralgias (36.5 vs. 23.9 %, p < 0.01) and surgery (p < 0.01), less ileal involvement (57.8 vs. 71.0 %, p < 0.01), and no differences for other extraintestinal manifestations or disease locations compared to Ca CD patients. AA UC patients were older at diagnosis, had an increased rate of arthralgias (28.6 vs. 14.6 %, p = 0.047) and ankylosing spondylitis/sacroiliitis (7.1 vs. 1.6 %, p = 0.035), with no differences for disease extent or rate of IBD-related surgeries compared to Ca UC patients. There were no differences in medication usage by race for CD and UC patients.
