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.

Ex Input:
Context: We hypothesized that self-reported pad use per day (PPD) after pubovaginal sling (PVS) correlated with postoperative quality of life (QOL) scores.', 'Two hundred fifteen women completed the incontinence impact questionnaire 7 (IIQ-7) and urogenital distress inventory 6 (UDI-6) before PVS and during follow-up. Starting 3 days before a visit, women recorded the number of protective urinary pad changes per day. Analysis of variance and Pearson correlation tests were used to determine if women reporting zero, one, or greater than or equal to two urinary pads per day after PVS had significantly different changes in baseline QOL scores.', 'Over a mean 8.5 months follow-up after PVS, 131, 56, and 28 women reported zero, one, and greater than or equal to two pad changes/day. Each pad group showed progressively less improvement from baseline IIQ-7 and UDI-6 scores after PVS. Change in IIQ-7 and UDI-6 scores negatively correlated with PPD (p < 0.0001).
Answer: Self-reported PPD after PVS reflects patient perception of urinary-specific QOL.

Ex Output:
Does self-reported pad use per day reflect patient quality of life after pubovaginal sling surgery?

Context: The aim of this study was to examine the utility of a hierarchical algorithm incorporating codes from the International Classification of Functioning, Disability and Health--ICF (WHO, 2001) and the International Statistical Classification of Diseases-ICD (WHO, 1994) to classify reasons for eligibility of young children in early intervention.', 'The database for this study was a nationally representative enrollment sample of more than 5,500 children in a longitudinal study of early intervention. Reasons for eligibility were reviewed and matched to the closest ICF or ICD codes under one of four major categories (Body Functions/Structures, Activities/Participation, Health Conditions, and Environmental Factors).', 'The average number of reasons for eligibility provided per child was 1.5, resulting in a population summary exceeding 100%. A total of 305 ICF and ICD codes were used with most (77%) of the children having codes in the category of Body Function/Structures. Forty-one percent of the sample had codes of Health Conditions, whereas the proportions with codes in the Activities/Partipication and Environmental Categories were 10 and 5%, respectively.
Answer: The results demonstrate that ICD and ICF can be jointly used as a common language to document disability characteristics of children in early intervention.

Ex Output:
Do iCF and ICD codes provide a standard language of disability in young children?

Context: The aim of this in vitro study was to evaluate the cytotoxicity of resin-modified glass-ionomer lining cements submitted to different curing regimes and applied to an immortalized odontoblast-cell line (MDPC-23).', "Forty round-shaped specimens of each experimental material (Fuji Lining LC and Vitrebond) were prepared. They were light-cured for the manufacturers' recommended time (MRT = 30 s), under-cured (0.5 MRT = 15 s), over-cured (1.5 MRT = 45 s) or allowed to dark cure (0 MRT). Sterilized filter papers soaked with either 5 microL of PBS or HEMA were used as negative and positive control, respectively. After placing the specimens individually in wells of 24-well dishes, odontoblast-like cells MDPC-23 (30,000 cells/cm2) were plated in each well and incubated for 72 h in a humidified incubator at 37 degrees C with 5% CO2 and 95% air. The cytotoxicity was evaluated by the cell metabolism (MTT assay) and cell morphology (SEM).", 'Fuji Lining LC was less cytotoxic than Vitrebond (p < 0.05) in all the experimental conditions. However, the cytotoxicity of Fuji Lining LC was noticeably increased in the absence of light-curing while the same was not observed for Vitrebond. The length of light-curing (15, 30 or 45 s) did not influence the toxicity of both lining materials when they were applied on the odontoblast-cell line MDPC-23.
Answer: The light-activation plays an important role in reducing the cytotoxicity of Fuji Lining LC. Following the manufacturer' recommendation regarding the light-curing regime may prevent toxic effect to the pulp cells.

Ex Output:

Does effect of curing regime on the cytotoxicity of resin-modified glass-ionomer lining cement applied to an odontoblast-cell line?
