There are seven birds in the tree. A bird was killed. How many birds are left?

No, there are still a few left on the tree. One fell to the ground and six flew to other places in fear.

Tell you a joke.

One day, the teacher wanted to test a student in class and asked him, "There are 10 birds in the tree. Shoot one, how many are left? "

The student asked, "Is it silent pistol?"

"No."

"How big is the gunshot?"

"80- 100 decibel."

"That means it hurts your ears?"

"yes."

"Is it illegal to shoot birds in this city?"

"No offense."

"Are you sure that bird was really killed?"

"ok."

The teacher is impatient. "Please tell me how much is left."

"OK, are there any deaf birds in the tree?"

"No."

"What's wrong with being in a cage?"

"No."

"Are there any other trees nearby? Are there any other birds in the tree? "

"No."

"Are there any disabled or hungry flightless birds?"

"No."

"Is it a bird in a pregnant belly?"

"Not really."

"Birds have flowers in their eyes? Guaranteed to be 10? "

"No flowers, 10."

The teacher was sweating profusely, and the bell rang, but the students continued to ask, "Are there any fools who are not afraid of death?"

"Everyone is afraid of death."

"Will you kill two with one shot?"

"No."

"Are all birds free to move?"

"Absolutely."

"If your answer is true," the student said confidently, "if the killed bird hangs on the tree and doesn't fall off, then there is only one left. If it falls, there will be none left. " The teacher fainted immediately!
