Exercise 1.3 - Answers



John will come to the party. The "because", as sometimes, but not always, signals a premise.


This is perhaps ambiguous. The conclusion could be "He will come to the party because he has been invited" (i.e. and not because he wants to). Or it could be "He will come to the party", with "he has been invited" as one of the premises.


They will. (i.e. Manchester United will beat Derby County.) "Since" is another word which is often used to signal a premise.


If she is right about such things, they will. Unlike "since", "if" does not signal a premise. It does not signal the presence of something which is being offered in favour of the conclusion.
