Explanation:

Each sentence is completed by choosing the modal verb (must, might, can't) that fits the logical context of certainty, possibility, or impossibility:

1. Logical necessity: Sabrina needs a new password because the old one fails.
2. Uncertain possibility: No decision has been made about baking.
3. Certainty of identity: The two look identical, so this is definitely his twin.
4. Impossibility of hunger: A big lunch means hunger is not possible.
5. Uncertain possibility: The final answer will come later, so attendance is not confirmed.
6. Impossibility of presence: Mia was seen in the library, so she can't be at the play.
7. Conditional possibility: Getting a new phone depends on cost, so it's a possible outcome.
