5. Which of the following sentences contains an italicized word that's used as a predicate adjective?
A. Jerry looks ill today.
B. Jerry looks at the map.
C. Jerry looks disdainfully at the pile of laundry.
D. Jerry looks into the microscope.
The sentence that contains a predicate adjective is A. Jerry looks ill today. A predicate adjective is the first adjective following a linking verb such as to be, or to look, in this case. The word "ill" is an adjective and it follows the verb looks. B is incorrect because "at the map" is a prepositional phrase. C is incorrect because "disdainfully" is an adverb, not adjective. D is incorrect because "into the microscope" is also a prepositional phrase, given that it starts with a preposition.
