In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Animals control the speed of motion to meet behavioral demands. Yet, the underlying neuronal mechanisms remain poorly understood. Here we show that a class of segmentally arrayed local interneurons (period-positive median segmental interneurons, or PMSIs) regulates the speed of peristaltic locomotion in Drosophila larvae.', 'PMSIs formed glutamatergic synapses on motor neurons and, when optogenetically activated, inhibited motor activity, indicating that they are inhibitory premotor interneurons. Calcium imaging showed that PMSIs are rhythmically active during peristalsis with a short time delay in relation to motor neurons. Optogenetic silencing of these neurons elongated the duration of motor bursting and greatly reduced the speed of larval locomotion.\Question: Does a group of segmental premotor interneurons regulate the speed of axial locomotion in Drosophila larvae?
Example Output: Our results suggest that PMSIs control the speed of axial locomotion by limiting, via inhibition, the duration of motor outputs in each segment. Similar mechanisms are found in the regulation of mammalian limb locomotion, suggesting that common strategies may be used to control the speed of animal movements in a diversity of species.

Example Input: Context: Platelet concentrates are important for support of patients with malignancies requiring myelotoxic chemotherapy. During storage, 10% to 15% of platelets may become activated resulting in the release of alpha-granules, which contain growth factors. We hypothesize that, during storage, growth factors accumulate in the plasma, specifically platelet-derived growth factor, vascular endothelial growth factor (VEGF), transforming growth factor-beta, and fibroblast growth factor-2, which may adversely affect cancer patients.', 'The concentrations of growth factors were measured by ELISA from the plasma of apheresis platelets serially throughout storage (days 1, 3, 5, and 7) and compared with concentrations in fresh plasma from healthy blood donors. Washing was evaluated as a method of growth factor removal, and an in vitro model of platelet transfusion in a patient receiving Bevacizumab (Avastin) using immunoprecipitation was employed to determine if Bevacizumab would be bound by the VEGF in apheresis platelets.', 'VEGF, platelet-derived growth factor, and transforming growth factor-beta were increased on day 1 versus fresh plasma and throughout storage reaching a relative maximum at outdate (P < 0.01, day 5 or 7). Fibroblast growth factor-2 concentrations were significantly increased on day 7 alone versus day 1 or to fresh plasma (P < 0.01). Washing removed 41 +/- 11% to 56 +/- 2% of the growth factors. Bevacizumab effectively bound the VEGF from apheresis platelets, with significant amounts of VEGF remaining in the supernatant.\Question: Do oncogenic and angiogenic growth factors accumulate during routine storage of apheresis platelet concentrates?
Example Output: Significant amounts of growth factors are present in apheresis platelets due to the isolation procedures, and these concentrations increase over storage, which may be partially removed by washing. In addition, apheresis platelet transfusion could affect cancer treatment by binding monoclonal antibodies directed against growth factors of tumor origin.

Example Input: Context: To estimate rates of heavy episodic drinking, alcohol abuse and alcohol dependence among U.S. adults 18-29 years of age and determine the relationship of these rates to student status and residence.', 'The analysis is based on data from a subsample of U.S. adults 18-29 years of age (N = 8666; 4849 female) who were interviewed as part of the 2001-02 National Epidemiologic Survey on Alcohol and Related Conditions (N = 43,093). Data were collected in personal interviews from a representative sample of adults 18 and older, living in households and selected group quarters in the United States, including Alaska, Hawaii and the District of Columbia.', 'Of all adults 18-29 years of age, 73.1% reported any drinking in the past year, 39.6% reported any heavy episodic drinking, 21.1% reported heavy drinking more than once a month and 11.0% reported heavy drinking more than once a week. Among past-year drinkers, these correspond to rates of 54.3% for any heavy episodic drinking, 28.9% for heavy drinking more than once a month and 15.0% for heavy drinking more than once a week. Although rates of heavy episodic drinking were slightly higher for college students than for noncollege students (p < .01), differences according to place of residence were greater than differences according to student status. Overall, 7.0% of adults ages 18-29 met the DSM-IV criteria for alcohol abuse in the past year, and 9.2% met the criteria for alcohol dependence. The prevalence of abuse was highest among students living off campus (p < .01), and rates of dependence were highest among students living on campus (p < .01).\Question: Do another look at heavy episodic drinking and alcohol use disorders among college and noncollege youth?
Example Output:
Heavy episodic drinking and alcohol use disorders are youth as well as college phenomena. Prevention campaigns targeted at all youth are needed to supplement interventions conducted at the campus level.
