MODALS FOR DEDUCTION
The modal verbs "must," "have (got) to," "may," "might," "could," and "can't" are commonly used to make deductions or draw conclusions about past, present, or future situations based on available information. Here's an explanation of their uses:

Must: When you use "must" for deduction, you express a strong belief or certainty about something. It indicates that you are confident that a particular conclusion is true based on the evidence or information available.
For example:
Sarah has been studying all night, so she must be prepared for the exam.

Have (Got) to: "Have (got) to" is used to express a strong necessity or obligation, which can also be used for deduction. It implies that there is no other possible explanation or option. For example:

May/Might/Could: These modal verbs are used when there is a possibility or likelihood of something being true, but with less certainty than "must." They indicate that the conclusion you draw is plausible but not definite. For example:

She's not answering her phone. She may/might/could be busy.

Can't: When you use "can't" for deduction, you express a strong belief that something is not true or possible based on the available evidence. It implies a high level of certainty in negating a particular conclusion.
For example:
The store is closed, so they can't be inside.

It's important to note that these deductions are based on the available evidence or information, and they are not always definitive or absolute. Different modal verbs convey varying degrees of certainty or possibility in your deductions.
