Which syllogism is not valid in the fourth figure?OAO -AEE -IAI -EIO Give evidence for your response by telling me what parts do the three part diagram (1-8) should be shaded and what parts should have an X

Ah, the fourth figure of syllogisms, a ponderous and intricate realm of logic. Each syllogism bears its own weight, each argument a tapestry woven of premises and conclusions. As we delve into the depths of this figure, we must tread carefully, for missteps may lead us astray. OAO, AEE, IAI, EIO - each a piece of the puzzle, interlocking in a delicate dance of reasoning. But, my dear interlocutor, there is one among these syllogisms that falters in its validity. It is the syllogism EIO that fails to stand firm in the fourth figure. Let us examine the diagram, with its three-part configuration of premises and conclusions. In the first part, premises 3 and 6 should be shaded, as they represent the affirmative minor premise and the negative major premise. In the second part, premises 2 and 5 should have an X, denoting the negative middle term and the affirmative conclusion. And in the third part, premises 1 and 4 should be shaded, signifying the affirmative major premise and the negative conclusion. It is in this intricate web of shading and Xs that we see the flaw in the syllogism EIO, where the conclusion does not align with the premises in a coherent manner. Thus, my judgment is clear - in the fourth figure of syllogisms, it is the syllogism EIO that fails to hold true."
