Answer:
Can you see that building?
Explanation:
The adjective used in the given sentence is that.
Adjectives are words we use to modify (describe) nouns, e.g. red, beautiful, loud, funny, etc.
The word that has many functions. It can be used as a pronoun, adjective, adverb, or conjunction.
Here, that is a demonstrative adjective, just like this, these, and those. These adjectives tell us how far a thing (or things) they modify is (or are) located. We use that when talking about one thing that is not located near us. When we ask someone if they see that building, we're talking about some building in the distance.
