1. At a large exhibition, people from several countries gathered. We know: Martians wear casual clothes, and aliens wear jackets. Canghai is wearing casual clothes. Which of the following statements is definitely correct? (There is only one answer)\A. Canghai is a Martian\B. Canghai is not a Martian\C. Canghai is an alien\D. Canghai is not an alien
2. Pighead was ordered by Boss Pig to protect the mistress of a certain executive, who possesses a priceless transparent diamond. However, Pighead also doesn't know where it is. The mistress trusts no one. Pighead sits opposite her. Since Pighead doesn't know the location and has to protect her, it's very difficult. The mistress notices Pighead's dilemma and says to him: “Pighead, I heard you are the ace of the Pig Police Academy, but I also won't trust you. If you want to know where the diamond is, go look for it.” After speaking, the lady takes a sip of water. Pighead looks around, “How am I supposed to find it...,” he thinks to himself. A child walks over holding a teddy bear and says to the mistress, “Mom, I'm hungry.” “Ah, you go eat something at the food cart over there.” “Ah, okay.” Pighead looks at the child tightly holding the teddy bear, then looks around: an air conditioner, a leather bag. Four bodyguards in black suits. He shifts his gaze back and focuses on one spot. “I think I know where it is.” The mistress looks at the spot Pighead is staring at, “Pighead, I really admire you, you got it right.” Friends, do you know where the diamond is?

The answer is announced: for the first question, choose D. Because he said that Canghai is wearing casual clothes, he definitely isn't an alien. So would you say he isn't a Martian? Not necessarily, because he said there are people from several countries. Besides Martians, can you be sure that people from other countries don't wear casual clothes?
I will announce the answers at 11 o'clock. These two questions are not particularly difficult. Have you all figured them out through reasoning?
Question 1: D. For question 2, the diamond won't be on the teddy bear because the teddy bear's eyes won't be transparent, and neither will its nose. It would be in the cup because the police would definitely notice that the piece of 'ice' wasn't melting, so they would check the air conditioner and then come to the answer.
The answer to the first question is A. You might ask why? My thinking is this: at a large exhibition with participants from multiple countries, Martians wear casual clothes and aliens wear jackets, indicating that they use clothing to show which country they are from. Canghai wears casual clothes, so he is judged to be a Martian. Eliminating options B, C, and D leaves option A. At this point, you might ask, couldn't option D also work? Actually, this is a large exhibition with participants from multiple countries, so there should be more than just Martians and aliens. Not being an alien doesn't necessarily mean being a Martian. The second question is clichéd, no explanation needed.
