    How could I know?

    Here is one of the questions in an exam preparation book.
    "Where has she gone?" "How ( ) I know?"
    1. could 2. might 3. should 4. would
    The book says the answer is 3. should.
    I thought both could and should were possible. The book doesn't say the reason "How could I know ?" is wrong. :(
    Would you kindly explain to me why?

    The right answer is "How should I know?"--it means : How am I supposed to know?- it expresses wonder


    "Should" expresses :
    -advice; suggestion: You should return those books to the library
    -duty, moral obligation: You should work a little harder...
    -possibility, probability: They should be at home by now.
    -wonder, surprise: How should I know?
    -criticism: You shouldn`t shout at your mother like that.

    "Could" expresses:
    -polite request: Could I borrow your pen?
    -suggestion : Maybe you could get someone to help you.
    -less than 50% certainty : Where is John? He could be at home.

    and many others

    You should search the web for further details.

    All the best,

    Re: How could I know?

    Thank you Sheena55ro for answering my question!

    I should say I'm still confusedů
    The reason why I thought "could" was possible is "could" expresses possibility and "How could I know?" was a kind of rhetorical question like "How could you do such a thing?". (I may be wrong!)

    I've just read other thread in this forum and been to an interesting site introduced in it (http://view.byu.edu/), and what I got is:
    How should I know --- 42 sentences
    How could I know --- 6 sentences
    How might I know --- 0
    How would I know --- 15 sentences
    Does this mean "How would I know?" is a possible answer???

    Need help!!!

    Re: How could I know?

    I think it's a bad question, because you could use 1/3/4 in the answer.
    How could/would = it's impossible for me to know
    should = it's none of my business to know
    I agree with you that 4 is definitely a possibility.

    PS Nice to see you're using that site, Kitty. It's worth getting to know the other features, like word + grammatical form, so you can look at things like word + gerund, etc.

    Re: How could I know?

    tdol, thank you very much for helping me!
    Your answer cleaned my confusion.
    I also thank you for telling us a useful web site and letting me know other interesting functions in the site! I hadn't realized the site had this feature until you mentioned it here. :)
    I tried searching "Good luck + preposition" and the result was good to know. I hope it'll help my writing as well.;)

    Cheers!
