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: To explore the antitumor effect of prescription consisting of Vitamin C (Vc) and Baicalin (PVB).', 'To explore the antitumor effect of PVB, using U14 cervical tumor-bearing mice model was used and the drugs were administrated through the gavages. Spectrophotometry was used to determine the content of superoxide dismutase (SOD), malondialdehyde (MDA) and cytokines IL-2, Il-4 and IFN-γ.', 'PVB had a better antitumor effect than baicalin and Vc used alone with an inhibition rate of 58.18% (p<0.05); PVB significantly improved the spleen index (p<0.01), and significantly reduced MDA content (p<0.01) but increased SOD activity in liver tissue and serum (p<0.01).

Example Input: To determine if adolescents with unilateral hearing loss (UHL) demonstrate worse language skills than their siblings with normal hearing (NH).', 'Case-control study of 12-17-year-old adolescents with UHL (20 cases) compared with sibling controls with NH (13 controls).', "Scores on the oral portion of the Oral and Written Language Scales (OWLS) and the Clinical Evaluation of Language Fundamentals (CELF) were the primary outcome measure. Wechsler's Abbreviated Scales of Intelligence (WASI) scores were also used as an outcome measure.", 'Adolescents with UHL demonstrated worse overall and expressive language scores than controls, (98 vs. 114, P=0.001; 100 vs. 114, P=0.006) and had significantly lower full scale (98 vs. 112, P=0.017), verbal (101 vs. 113, P=0.032), and performance IQ (95 vs. 107, P=0.037).

Example Input: Structural abnormalities of the anterior cingulate cortex (ACC) may interfere with the interaction of cortical and limbic networks involved in emotional regulation and contribute to chronic depressive syndromes in the elderly. This study examined the relationship of regional anterior cingulate cortical volumes with treatment remission of elderly depressed patients. We hypothesized that patients who failed to remit during a 12-week controlled treatment trial of escitalopram would exhibit smaller anterior cingulate gray matter volumes than patients who remitted.', 'The participants were 41 non-demented individuals with non-psychotic major depression. After a 2-week single-blind placebo period, subjects who still had a Hamilton Depression Rating Scale (HDRS) of 18 or greater received escitalopram 10 mg daily for 12 weeks. Remission was defined as a HDRS score of 7 or below for at least 2 consecutive weeks. The patient sample consisted of 22 depressed patients who achieved remission during the study and 19 depressed patients who remained symptomatic. High-resolution magnetization-prepared rapidly acquired gradient echo (MPRAGE) sequences were acquired on a 1.5 T scanner and regional ACC volumes were manually outlined (dorsal, rostral, anterior subgenual, and posterior subgenual).', 'Repeated measure analyses revealed that patients who failed to remit following escitalopram treatment had smaller dorsal and rostral anterior cingulate gray matter volumes than patients who remitted, whereas subgenual cortical volumes did not differ between the groups.
