Usage Note :
You can use as, because, since, or for to give an explanation for something. Because is the commonest of these, and is used when answering a question beginning with ‘why?’.You can use as or since instead of because to introduce a clause containing a reason for something, especially in writing. …a note about The National Portrait Gallery, as the word ‘Gallery’ can be misleading… Since the juice is quite strong, you should always dilute it.
