It snowed heavily one night, and the temperature dropped to -5 degrees the next morning. The detective questioned the suspect in the case. When asked if she had any evidence that she was not at the crime scene at around 11 o’clock last night, the single woman replied: “At around 9 o’clock last night, my old TV broke down and caused a short circuit and power outage. Because I lacked knowledge of electricity and could not repair it myself, I took a sleeping pill and went to sleep. This morning, less than 30 minutes ago, I called the electrician, and he told me that I would have power as long as I turned on the switch at the front door.”
However, when the detective scanned the entire house and his eyes fell on the large glass fish tank by the window, he immediately saw through the woman’s lie. What did the detective find?

“Where were you last Sunday?” the sheriff asked a suspect. “I was climbing a mountain. Look, this is the photo of me on the top of the mountain. After reaching the top, I felt a sense of accomplishment, so I decided to drink a can of beer and put the camera in a suitable position to take a selfie of the moment I opened the beer. After returning, I named this photo “Drinking a Celebration Wine.” “The suspect said, while taking out a photo to show the sheriff. The sheriff looked at the photo and said, “The scenery is very good, and there are clouds on the mountainside. The mountain you climbed must be very high.” “Hey, it’s very high, 3,500 meters.” The man thought that the detective believed his alibi and answered quite proudly.
“But,” the sheriff’s face suddenly changed, and he said sternly, “You are lying, this photo is fake!” What is the flaw in this photo?

A suspect in a murder case was camping in the mountains, and Detective Anne drove to investigate. Anne entered the suspect’s tent on a green patch between the mountains.

The suspect argued that he picked them up in the mountains. He had lived in this tent for more than a month and had never been to the city.
Anne said: “You need to make up a new lie.” So, where did Anne see the flaw?
