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: We examined whether or not continuous arteriovenous hemofiltration (CAVH), in the absence of renal failure, would improve either hemodynamic abnormalities or survival in a canine model of septic shock.', 'Escherichia coli 0111, as an intraperitoneal clot, was surgically implanted into 21 one- to two-year-old purpose-bred beagles. The dogs were randomized to no CAVH (control group, n = 7), sham CAVH (extracorporeal circulation without hemofiltration, n = 7), or true CAVH (hemofiltration with removal of 600 mL/hour of ultrafiltrate, n = 7). Hemofiltration began one hour after clot implantation and continued for six hours. All dogs received antibiotics and had serial hemodynamic and laboratory evaluations.', "During the first seven hours of the study, all dogs displayed a progressive, significant decrease in mean arterial pressure, cardiac index, left ventricular ejection fraction, and serum pH (all p < 0.05). Two of seven dogs in the control group, one of seven dogs in the sham CAVH group, and one of seven dogs in the true CAVH group survived seven days after clot implantation. True CAVH, which included fluid replacement with lactated Ringer's solution, significantly increased serum lactate and decreased serum bicarbonate levels after six hours (both p < 0.05). However, pH did not differ between the three treatment groups (p > 0.20). Continuous arteriovenous hemofiltration therapy had no significant effect on cardiovascular abnormalities or survival.
