Teacher: Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.
Teacher: Now, understand the problem? If you are still confused, see the following 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).
Solution: 1
Reason: There is a line in the passage which say 'The aim of this study was...' which suggests that it is talking about a specific aim. Hence, the output should be 1 as this passage has a definite aim.

Now, solve this instance: Magnesium (Mg) is an essential cofactor for enzymes involved in glucose and insulin metabolism. Low intakes of dietary magnesium may be linked to greater risk of metabolic syndrome (MS) in older adults.', 'The objective of this study was to examine the cross-sectional relationship between dietary Mg intake, metabolic risk factors and MS in elderly adults.', 'This study was conducted in a sample of 535 (179 men and 356 women) community-living adults aged 60 years and in Boston Massachusetts between the years 1981 and 1984. Dietary Mg intake was assessed by a 3-day food record and categorized by quartiles of dietary intake. The MS was defined based on criteria set by the Third Report of the National Cholesterol Education Program except that body mass index was used in place of waist circumference. Logistic regression analysis was used to examine the association between quartile categories of Mg intake, prevalence of MS and components of the MS. Models were adjusted for age, gender, BMI, race, educational attainment, marital status, smoking status, alcohol intake, exercise, energy intake, percentage of calories from saturated fat, use of antihypertensive or lipid medication.', 'Mg intake was inversely associated with the MS; those with the highest intake of Mg had significantly lower risk of having MS compared to the lowest quartile of intake (OR: 0.36, 95% CI 0.19-0.69, P for trend 0.002). Significant inverse relationships were observed between Mg intake and BMI (OR: 0.47, 95% CI: 0.22-1.00, P trend = 0.03), and fasting glucose (OR: 0.41, 95% CI 0.22-0.77, P trend = 0.005).
