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.

Let me give you an example: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 ± 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
The answer to this example can be: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
Here is why: The question is based on the following sentences from the passage (i) Group 2 innate lymphoid cells (ILC2s) {ii) In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (iii) As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. and (iv) They were also associated with increased blood eosinophilia

OK. solve this:
To ascertain body temperatures in older people.', 'Analysis of oral temperatures obtained from elderly subjects residing in the community and nursing home.', 'A single nursing home, office setting, and community center.', 'One hundred nursing home residents and 50 subjects residing in the community.', 'Three oral temperatures were measured in nursing home residents and once in community dwellers using an electronic digital thermometer.', 'The average age of subjects was 80.7. Temperatures ranged from 94.0 degrees F to 99.6 degrees F. In nursing home subjects, the 6 a.m. mean temperature was 97.3 degrees F, 4 p.m. mean was 97.4 degrees F, and 10 p.m. mean was 97.8 degrees F. The single midday mean temperature in community dwellers was 97.7 degrees F. Ninety-seven of 100 (97%), 94 of 100 (94%), and 83 of 96 (86%) recordings were below 98.6 degrees F in nursing home residents at 6 a.m., 4 p.m., and 10 p.m., respectively. Similarly, 45 of 50 (90%) community dwellers had midday temperatures below 98.6 degrees F. Repeated-measures analysis demonstrated an increase in temperature during the day. The increase was greatest in the youngest old, with no significant change in body temperature over the course of the day in the oldest old.
Answer:
Is older colder : temperature range and variation in older people?
