Final answer:
The phrase suggests that time is a finite resource and should be managed carefully, making time management crucial.
Step-by-step explanation:
The phrase 'Remind yourself that time is our most precious resource' conveys the importance of time management and the concept of scarcity of resources, suggesting that we should use our time wisely as it is limited. Given that there are only twenty-four hours in a day, we must make choices about how we allocate this time, and these choices inherently mean we cannot do everything we might want to. This phrase emphasizes the value of time, underscoring its finite nature and the need for careful decision-making in how we use it. The correct answer to the student's question is C) Time management is crucial.
