by putting his head down of it
Hello. You have not submitted the arguments to which this question refers, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
A persuasive argument is one that has the capacity to convince the reader about something. The author of this argument wants the reader to agree with what he is presenting and for this reason uses several evidences and supporting information to show that the argument is valid, true and that it must be adopted by the reader. Therefore, to answer this question, you must first read the arguments and see which one has less evidence, failing to show that it is correct and that it must be believed. In this case, this argument is the least persuasive.
1. The worst thing about being poor, (according to Junior's opinion), is that his family doesn't have enough money to take his dog, Oscar, to the vet.

She looked hard at me. And her eyes weren’t dark anymore, so I knew that she was going to tell me the truth. And trust me, there are times when the last thing you want to hear is the truth. “Junior, sweetheart,” Mom said. “I’m sorry, but we don’t have any money for Oscar.”

3. Junior got very angry at his Dad, because his Mom and Dad made a decision without him, even though it included HIS beloved pet, Oscar.
"Then Dad came home from wherever and had one of those long talks with Mom, and they decided something without me. And then Dad pulled down his rifle and bullets from the closet."
