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.

[EX Q]: We investigated the effects of pulsed ultrasound on swelling, muscle soreness perception, relaxed-elbow extension angle, and muscular strength.', 'Eight sets of concentric and eccentric actions induced delayed-onset muscle soreness of the elbow flexors. Group 1 received 20% pulsed ultrasound treatments (1-MHz, 7 minutes, 1.5 W/ cm(2) temporal peak intensity) twice a day immediately after postexercise assessments and at 3, 24, 27, 48, 51, 72, and 75 hours postexercise. Group 2 received sham treatments immediately after postexercise assessments and at 3,27, 51, and 75 hours postexercise and true treatments of pulsed ultrasound at 24, 48, and 72 hours postexercise. Group 3 received sham treatments of no ultrasonic output immediately after postexercise assessments and at 3, 24, 27, 48, 51, 72, and 75 hours postexercise.', 'Thirty-six college-age females.', 'We recorded upper-arm circumference, perceived soreness, relaxed-elbow extension angle, and elbow-flexion strength before (pretest), immediately postexercise, and at 24, 48, 72, and 96 hours postexercise.', 'We noted differences over time but no treatment effect between groups or interactions between time and group for upper-arm circumference, perceived soreness, relaxed-elbow extension angle, or elbow-flexion strength.

[EX Q]: Humans can easily restore a speech signal that is temporally masked by an interfering sound (e.g., a cough masking parts of a word in a conversation), and listeners have the illusion that the speech continues through the interfering sound. This perceptual restoration for human speech is affected by prior experience. Here we provide evidence for perceptual restoration in complex vocalizations of a songbird that are acquired by vocal learning in a similar way as humans learn their language.', "European starlings were trained in a same/different paradigm to report salient differences between successive sounds. The birds' response latency for discriminating between a stimulus pair is an indicator for the salience of the difference, and these latencies can be used to evaluate perceptual distances using multi-dimensional scaling. For familiar motifs the birds showed a large perceptual distance if discriminating between song motifs that were muted for brief time periods and complete motifs. If the muted periods were filled with noise, the perceptual distance was reduced. For unfamiliar motifs no such difference was observed.
[EX A]: Does stimulus familiarity affect perceptual restoration in the European starling ( Sturnus vulgaris )?

[EX Q]: This pilot study, the first of its type, was conducted to determine the clinical outcome of glaucoma drainage implant (GDI) surgery supplemented with injectable crosslinked hyaluronic acid (HA) in patients with severe glaucoma.', 'This was a retrospective chart study involving 10 eyes of 10 patients with severe glaucoma (glaucomatous visual field loss worse than -20 dB) who had previously undergone GDI surgery supplemented with crosslinked HA with a 2-year follow-up. Surgical success was defined as intraocular pressure (IOP) &lt;21 mm Hg with a reduction of ≥40% (definition A) or ≥50% (definition B) from baseline IOP on 2 consecutive follow-up visits, IOP &gt;5 mm Hg on 2 consecutive follow-up visits, and neither reoperation of glaucoma nor loss of light perception vision.', 'The mean ± SD baseline IOP before GDI was 38.5 ± 10.7 mm Hg, and the mean IOP at the last follow-up visit was 13.0 ± 5.0 mm Hg, with a mean pressure drop of 24.4 ± 10.9 mm Hg (62%; p = 0.005). According to definition A, life-table analysis showed an overall success rate of 80%, while according to definition B, the success rate was 50% after 24 months of follow-up. Complications were infrequent and not serious. No complications resulting from the reticulated HA therapy itself were observed.
