In this exercise, you are to pick out those sentences from a list which have a given logical form. For instance, on this first page, you are asked to pick out sentences with the form ~P&Q. All this form means is that the main connective of the given sentence is '&' and the first conjunct of this sentence is a negation. (Thus '~(AvS)&M' counts but '~Av(S&M)' does not. The latter has 'v' as its main connective.)
Which of the following sentences have the form '~P&Q'?
