2.	a.	Two ways ambiguous:
		i)	`Everyone is such that (he or she works toward some goal)`.
		ii)	`Some goal is such that (everyone works toward it)`.
			(ii) implies (i).
	b.	Not ambiguous
	c.	Four ways ambiguous:
		i)	`Every day is such that (someone eats at a restaurant on that day)`.
		ii)	`Someone is such that (every day is such that (he or she eats at a restaurant on that day))`.
			[Notice that, although `that day` is a demonstrative phrase (and might thus be counted an individual term), it does not have a reference independent of the quantifier phrase `every day`. It therefore functions here like a pronoun with `every day` as its antecedent. The phrase `the truck` has a similar function in `A truck struck a car but only the truck was damaged`.]
		iii)	`A restaurant is such that (every day is such that (someone eats at it on that day))`.
		iv)	`Some person and restaurant are such that (he or she eats at it every day)`.
			(iv) implies all the others; (ii) and (iii) each imply (i).
