Explanation:
A prepositional phrase is a group of words that contains a preposition (e.g. <em>in, on, near, by, for</em>, etc), its object, and words that modify the object. The object can be a noun, a gerund (a verb form ending in <em>-ing</em> that acts as a noun), or a clause.
In the <em>Answer</em> section, you can see the correct answers. I have pointed out the prepositional phrases (what you are supposed to underline once) and have underlined the objects (what you are supposed to underline twice). Like this, we can clearly see what the elements of prepositional phrases are.
