False. 'Must' can be used for both obligation and deduction. For obligation: 'You must complete the form.' For deduction: 'She must be at home because her car is here.' The context determines the meaning. In deduction, 'must' shows logical certainty, while in obligation, it shows necessity. Other modals like 'may' and 'can' also have multiple uses, so it's important to consider the sentence context.
