Explanation:

🆕 New Concept Discovered: Commas after Introductory Phrases
Separating setup information from the main clause

Step 1: Identify the main clause

The main clause contains the primary subject and verb that can stand alone as a complete sentence.

In this sentence, the main action is:
"Marvin found the information he needed."

• Subject: "Marvin"
• Verb: "found"

Step 2: Identify the introductory phrase

Everything that comes before the main clause is the introductory phrase, which sets the stage (telling us where or when the action happened).

The introductory phrase is:
"On the last page of the textbook"

Step 3: Place the comma

A comma should be placed immediately after the introductory phrase to separate it from the main clause.

• Sentence: "On the last page of the textbook Marvin found the information he needed."
• With comma: "On the last page of the textbook, Marvin found the information he needed."

Looking at the selection options in the image:

• Triangle 1 is after "page"
• Triangle 2 is after "textbook"
• Triangle 3 is after "found"

The comma belongs after "textbook" (the second triangle).

Answer:

After the word textbook (the second triangle).

The corrected sentence is:
"On the last page of the textbook, Marvin found the information he needed."
