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 Input:
The aim of this study was to develop an assay system that can quantify the amount of biomass in biofilms formed by different isogenic mutants of an Escherichia coli K-12 strain.', 'The reported assay, which is based on the BacTiter-Glo assay from Promega, uses bioluminescence to detect the intracellular concentration of ATP, which correlates with viable bacterial cell numbers. The quantitative data obtained with this ATP assay were compared to those obtained with the conventional crystal violet assay. As a qualitative control, scanning electron microscopy was performed.

Ex Output:
Does a combination of assays reveal biomass differences in biofilms formed by Escherichia coli mutants?

Ex Input:
Psoriasis profoundly affects patient quality of life (QOL). Amevive (alefacept), a novel and selective biologic agent, was clinically effective and significantly improved QOL in a phase 2 study.', 'The present placebo-controlled, randomized phase 3 study examined the effects of a 12-week course of intramuscular alefacept on QOL in 507 patients with chronic plaque psoriasis using both dermatology-specific questionnaires [Dermatology Life Quality Index (DLQI); Dermatology Quality of Life Scales (DQOLS)] and the Short Form-36 Health Survey (SF-36), a generic, general health questionnaire.', 'All 3 QOL measures (DLQI, DQOLS, SF-36) demonstrated that alefacept 15 mg was significantly more effective than placebo in improving QOL in patients with chronic plaque psoriasis. In addition, the improvements in QOL for patients in the alefacept 15 mg group were of similar magnitude for all 3 QOL measures.

Ex Output:
Does intramuscular alefacept improve health-related quality of life in patients with chronic plaque psoriasis?

Ex Input:
The study focuses on the analysis of the possible relationship between a common NYD-SP18 (rs6971091, G>A) gene polymorphism and weight loss after lifestyle intervention (combined dietary intake and physical activity) in overweight/obese females.', 'We genotyped 139 unrelated non-diabetic Czech females (49.5 13.3 years, average BMI at baseline 32.2 4.6 kg/m. Biochemical and anthropometrical measurements were performed before and after ten weeks of lifestyle intervention.

Ex Output:
Do body Composition Changes in Adult Females after Lifestyle Intervention Are Influenced by the NYD-SP18 Variant?
