Explanation:

Prepositional phrase is a group of words that starts with a preposition, and, besides it, contains a noun or a pronoun (at three o'clock, on the table, with all my heart, under the bed etc.)

Now, "with my dryer" seems like a no-brainer, the only question is "Is it the only prepositional phrase?"

Some might identify "to fix" as the other phrase. However, although it starts with "to" it doesn't function as a preposition here, it only serves to build an infinitive. Additionally, "fix" is a verb, not a noun nor a pronoun, so this can't be regarded as prepositional phrase by any means.

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.
