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.

Example input: 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).
Example output: 1
Example explanation: 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.
Q: Middle third clavicular fracture is effectively treated by conservative means. Previous studies showed that comminution and displacement of clavicular fractures might affect fracture healing. However, the clavicle horizontally aligns in the shoulder girdle and has different biomechanics from vertical weight-bearing bones. Therefore, this study was conducted with the hypothesis that comminution has no effect in worsening fracture healing and union configurations in conservatively treated middle third clavicular fractures.', 'One hundred ninety-eight middle third clavicular fractures treated by conservative means were reviewed and divided into 2 groups. Group 1, simple fractures, included 97 patients. Group 2, comminuted fractures, included 101 patients. Patient demographic data, initial fracture deformities, and union configurations such as angulation, overlying, and displacement were measured. Union rate and union complications such as delayed nonunion were evaluated. Data were analyzed for statistically significant differences (p<0.05).', 'Initial deformities of Group 1 and Group 2 were 11.949.59 and 9.408.57 angulation, 12.2412.96 and 11.7610.06 mm of overlying, and 13.318.63 and 13.727.42 mm of displacement, respectively, and exhibited no significant differences (p>0.05). Union rate and union complications of Group 1 were 74/97 (76.29%) and 23/97 (23.71%), respectively. For Group 2, the rates were 82/101 (81.19%) and 19/101 (18.81%), respectively. Union configuration of Group 1 and Group 2 were 13.7610.63 and 12.808.65 angulation, 11.9310.75 and 11.529.38 mm of overlying, and 9.798.33 and 10.746.68 mm of displacement, respectively, and showed no significant differences between the groups.
