Hi Julia,

As in any other language, there are always different ways of expression a certain idea so there are always alternatives. For example, instead of saying 'a valuable collection of paintings' you can say 'a priceless collection of paintings', 'an invaluable collection of paintings' or 'a unique collection of paintings'.

By the way, 'any other alternatives' is a tautology.
