Ask yourself what part of speech "two" is- both are completely different parts of speech, but one of your answers is right
In the sentence "The two sisters lived in Yorkshire, England," the subject is "two sisters."

In this case, the action being performed is "lived," and it is the two sisters who are doing the living. Therefore, "two sisters" is the subject of the sentence.
