The correct answer to this open question is the following.
Although there are no options provided, we can say that the organizational pattern Tomas is using for his speech is the Refutation Pattern.
This is the correct answer because in the Refutation Patter, the speaker search for the probable opposition arguments of its audience to prepare the right answers and arguments before its speech. This way he/she could have the best answers and the way to supporting when the speaker is faced with oppositions.
That is what Tomas is doing, for his persuasive speech. He first identified all the objections to his position, and then he used evidence to argue against those objections.
