Answer:
3. He wants to give his dinner to the dog.
Step-by-step explanation:
Although it isn't stated specifically, we can make an inference that Matt will feed his dinner to the dog.
The phrase, "...Matt knew that "Everyone's Favorite Soup" was not his favorite soup," tells us that Matt does not want to have the soup.
Next, from the sentence, "Matt saw his chance and took it," we can guess that Matt is about to get rid of his soup.
So, from the information given, we can guess that Matt will give Dusty his soup.
The answer, then, is 3. He wants to give his dinner to the dog.
Good luck ^^
