Sister Zhao's son is in the fifth grade of primary school, and today he caused a small sensation, because he brought a magic question of Olympiad Peiyou, which shocked all the childless young people in the institute, and suddenly felt a lot of pressure.

"There was a bear that fell into a trap 19.617 meters deep and fell for exactly 2 seconds. What color is the bear? The 5 alternative answers are "white", "brown", "black", "dark brown", "gray".

Got sick, fell into a trap, and it has something to do with color?

Yuan Xiaochun said that he didn't have a stubble, and his mind was not thinking about it......

"Koharu, the director is looking for you."

Hurry up and take back your brain hole and do serious things.

Koharu returned to the director's office, uneasy.

Last time, I didn't become a standard-bearer because I had "high hopes", and this time I have to order something to come down and mess up......

I didn't think that there was still a person sitting in the office, about 40 years old, with a tough appearance and resolute eyes.

"This is Yang Jieli, political commissar of the Criminal Police Department of the State Bureau, Xiaochun, I have a case today that I want to learn about the situation from you." Fu said,

Case? Xiao Chun's heart was stunned, what case would find her?

Political Commissar Yang Xu saw her doubts and smiled at her, "Comrade Yuan Xiaochun, yes, it's like this, it's about a case of Shangyuan Temple, we found that there is an old house in your family next to Shangyuan Temple in the process of handling the case." ”

Koharu nodded, "Yes." ”

"That's good, just check with you, did Shangyuan Temple summon the heads of several old houses next to you to discuss the expansion half a year ago?"

"Yes, my father went to the meeting."

"Why did you finally tear down the one on the left, and you didn't move?"

Xiaochun was embarrassed, although it was forced by the temple, after all, it was similar to "bribery", she was very embarrassed. But still bluntly speaking,

"Because my family paid the money according to what the monk said, Shangyuan Temple said that if we donate these sponsorship fees, it will also be regarded as reinforcing Buddhism, and the house will be preserved."

"Oh, how much was donated,"

"700,000."

Koharu didn't dare to look at them anymore, his head was lowered, it really looked like he had done something bad.

"Okay," Commissar Yang got up and reached out to shake her hand, "We'll check the situation, thank you." ”

Koharu comes out,

My heart is more troubled,

What's going on? Otherwise, how could it alarm the criminal police department of the state bureau......

Before the lunch break, I received a call from He Yan,

"I'll pick you up and meet the doctor."

Koharu hurriedly said, "You say the ground, I'll go by myself!" ”

A state celebration he almost swept the whole city, what did he say like when he came!

He Yan didn't seem to want to trouble her, but insisted on picking her up, and both of them took a step back and made an appointment to meet at the entrance of the alley one stop away from the station.

Koharu walked over first, but after only a few steps, a car stopped her.

Xiaochun was startled, thinking it was He Yan, and was about to get angry, when the car window rolled down, it was the Yang political commissar just now?

"I'm sorry to scare you." Lao Yang regarded her "about to get angry" as frightened, and hurriedly appeased. Koharu shook his head, "It's okay, it's okay,"

"Do you have anything else to do now, then we'll find time to talk about it."

"It doesn't matter, you can say it."

"Okay, get in the car first, I'll make a long story short."

Lao Yang drove the car forward a little bit and pulled over.

After looking at her and thinking about it again, he said solemnly,

"I'll tell you the truth, I saw that side just now because I wanted to test you. In fact, we already know the information I just asked, and your answer is very frank. ”

Koharu looked at him in surprise!

He nodded slightly, "You are also a policeman, you should know that the case usually does not go to the criminal police department of the state bureau, and I didn't reveal all the facts of the case in front of your office just now." I'm looking for you alone because after what I've just observed, I think you can help us investigate something. This is not to tell you that when we analyzed the case, after research, we felt that the matter of your old house involved Shangyuan Temple, and you are a police officer yourself, so you are the most suitable person to cooperate with our case, but I still don't feel at ease......" He smiled, "So I took a look at it today." ”

Koharu nodded, also very solemnly, "I understand this." In fact, when I first paid the 700,000 yuan, I also had concerns, but after all, it was an old house left by my grandfather, and I was very emotional, so I didn't think much about it, just leave the house after the money is paid......"

Xiaochun is so real, it seems that Lao Yang is more relieved,

"Is the person who collects your money a great monk named Changhe?"

"Yes."

"He's dead."

Koharu looked up, his eyes wide open. Sure enough, there was a murder!

"Not only that, some antique treasures in Shangyuan Temple have also been stolen one after another, especially a set of Dehua white porcelain tea sets, which is very important." Lao Yang looked at his watch, "That's it, you come to the criminal police department tomorrow, and we'll talk about it in detail." It's just a reminder here, because the case is complicated, so I hope you will keep it secret for the time being, and don't say much in the office. ”

Koharu nodded, "I know." ”

Until she got into He Yan's car, Xiaochun still seemed a little absent-minded, she was thinking about the case.

"What do you think, soul?"

He Yan drove away, she was silent, He Yan reached over and pulled her face.

Koharu slapped his hand "Nasty." "The frown is old and dead,

He Yan smiled evilly, "Don't say it, let's stop and talk wildly." ”

Xiaochun's brain turned quickly, and he crossed him, "I'm thinking about an Olympiad math problem, I guess you can't do it with a perverted pig brain." ”

He Yan smiled lightly at this time, "Let's hear it." ”

"There was a bear that fell into a trap that was 19.617 meters deep and fell for exactly 2 seconds. What color is the bear? She also made it more difficult and didn't tell him the alternative answers.

He Yan was really silent.

Thinking that he couldn't answer, Koharu felt proud, turned his head to look out the window again, and continued to think about himself.

suddenly

"Black." He said.

Xiaochun looked at him, still disdainful, "Don't talk nonsense, anyone can get one." ”

He leaned back in his chair relaxedly, flicked the steering wheel freely, looked ahead, his lips slightly curved,

"The trap is 19.617 meters deep and the fall time is 2 seconds, so g = 9.8085, indicating that the latitude of the trap is about 44 degrees. According to the geographical distribution of bears, there are no bears in the southern hemisphere, and it can be confirmed that it should be 44 degrees north latitude.

Design a ground trap for a bear, and that must be a terrestrial bear. Most terrestrial bears have poor eyesight and have difficulty distinguishing traps, so they are prone to falling into them.

In the case of terrestrial bears, there are the following bear species: brown bear, American black bear, and Asiatic black bear. Since the trap is 19.617 meters deep, the soil must be the impact parent material, so that it is easy to excavate. Although brown bears have geographical distribution, they are mostly high-altitude areas, and they are fierce, the risk factor of hunting is large, and the value is not as high as that of black bears, and the general bear paws and bear bile are taken from black bears. And because the geographical distribution of black bears does not coincide with brown bears, it can be determined: black. It was the black bear that fell in. ”

Yuan Xiaochun is stupid!
