Jasmine's goal to run a four-minute mile by doing two sprints three times per week for four months is quite specific in terms of the actions she plans to take (running sprints) and the timeline (three times per week for four months). However, the goal of running a four-minute mile is considered unrealistic for most individuals, as it is an elite level of performance typically achieved by highly trained athletes.
Based on this analysis, the most likely response from her track coach would be:
It is specific but not realistic.
