Which option would you put in the following sentence "Caroline may ... go away next week. The sentence was taken from a grammar book  .You are supposed to put the right form of either  must or have to . The only one which I  can think of  is  may be able  , but it comes from  can. Cheers  in advance

...may have to go away...
(may and must never go together as far as I can recall)
it could be that her company is making her go somewhere (for example).

Douglas recalled it right: Modals don t go together. Hence, your answer is have to . Meaning: It s not sure, but there are signs in the air she may have to go away. I may have to do some more work, but I don t know yet. It depends on my boss and other circumstances. Hope this helps. Peter

Have to is not really a true modal verb. It is a semi-modal. That is why it is the correct option. Two modals cannot go together. However, a modal and a semi-modal verb can.

I hope that helps explain why one is correct and the other isnt.
