Here's how to identify the prepositional phrase and underline the complete object of the preposition in the sentence:
The Lord solved the problem (with an unusual decree).
- Underline the complete object of the preposition "with": an unusual decree.
- Draw an arrow from the prepositional phrase to the word it modifies (in this case, "solved").
So, it looks like this:
- Prepositional Phrase: (with an unusual decree)
- Underlined Complete Object: an unusual decree
- Arrow to the word "solved":
The Lord solved the problem → (with an unusual decree)
↑
an unusual decree
