Hello everybody!

If I use "which one", is it wrong?

1. Either we go by train or we rent a car. Which do you prefer?
2. Either of the children can come with us; we don't mind which.

    No. 'Which one' is better than 'which' in the second sentence. It sounds a little abrupt to use a bare 'which' when speaking of people.

    I would say 'which', but there is very little in it. If you hadn't mentioned 'car' and 'train' (suppose you had written 'either we drive or we fly') then I would be more strongly in favour of 'which', but I cannot think of an example where you could not use 'which one'.

    If the choice is between objects ('You can either have a pear or a peach'), then I would say 'which one', but 'which' isn't wrong.
