... How can both p and q be false, and pq be true? •Think of p as a “contract” and q as its “obligation” that is only carried out if the contract is valid. •Example: “If you make more than $25,000, then you must file a tax return.” This says nothing about someone who makes less than $25,000. So the imp ...

Because the addition of an adjunct to a head leaves the result category the same as the head’s category, one can continue to add on more and more adjuncts at will: this is because the highest phrasal category in the tree will always be the same category (here, A) as the one below it.
