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.

[EX Q]: The extent to which tolerance acquired in one motion environment can be transferred to another has not been fully elucidated. This study compares three provocative motion stimuli and whether tolerance acquired from cross-coupled motion and torso rotation can be transferred to simulated aircraft motion.', "There were 18 healthy subjects (9 men and 9 women), 18-44 yr of age, who were divided into 3 groups. Each group was exposed to the following desensitization procedure in a pseudo-random repeated measures design. In condition D1, subjects were exposed to 4 consecutive days of cross-coupling and on the 5th d they were exposed to simulated aircraft motion. In D2, subjects were exposed to 4 consecutive days of torso rotation and on the 5th day they were exposed to the simulated aircraft motion as in D1. In D3, subjects were exposed to 5 consecutive days of simulated aircraft motion. Based on Graybiel's diagnostic criteria, severity of motion sickness on the 1st and 5th day in D1, D2, and D3 were compared.", 'Cross-coupled motion was the most provocative stimulus followed by torso rotation and simulated aircraft motion. Within each motion stimulus, there was evidence of desensitization (p < 0.001) within 4 d. There were no significant differences in the severity of motion sickness observed on the 5th day regardless of the desensitization stimuli.

[EX Q]: To describe the novel use of a chorioretinal biopsy technique to confirm the microbiological diagnosis of endogenous Escherichia coli (E. coli) endophthalmitis, when other investigations have been proven nondiagnostic.', 'Case report of an 82-year-old white man with endogenous endophthalmitis without a clearly identifiable source of infection.', 'After systemic cultures and multiple aqueous and vitreous samples were unable to identify a causative organism, chorioretinal biopsy of a subretinal abscess was used to confirm the microbiological diagnosis. This ensured appropriate ophthalmic and systemic treatment of infection.

[EX Q]: Stem cells within the intestinal epithelium generate daughter cells that undergo lineage commitment and maturation through the combined action of the Wnt and Notch signaling cascades. Both pathways, in turn, regulate transcription factor networks that further define differentiation toward either enterocytes or 1 of 3 secretory cell lineages (Paneth, goblet, or enteroendocrine cells). In this study, we investigated the role of the Wnt-responsive, Ets-domain transcription factor Spdef in the differentiation of goblet and Paneth cells.', 'The in vivo function of Spdef was examined by disrupting the Spdef gene in mice (Spdef(-/-) mice) and analyzing the intestinal phenotype using a range of histologic techniques and DNA microarray profiling.', 'In accordance with expression data, we found that loss of Spdef severely impaired the maturation of goblet and Paneth cells and, conversely, led to an accumulation of immature secretory progenitors. Spdef appears to positively and negatively regulate a specific subset of goblet and Paneth cell genes, including Cryptdins, Mmp7, Ang4, Kallikreins, and Muc2.
