Virus test in mice

 

The questions are as follows:

There are 1000 Identical bottles in the lab, but one of them is toxic. You can use lab mice to test which bottle is a poison. If the mouse drinks the poison, it will die in a week. The potion in other bottles has no side effects. Could you tell me the minimum number of mice that can be used to find out which bottle is poison within a week:
A.9
B. 10
C. 32
D. 999.
E. None of the above

 

1111111111 (1023)-10000 (16)-100 (4)-10 (2)-1 (1) = 1111101000 (1000), which is 1000 in decimal format. Let the bottles and mice be arranged in a column. When the station is ready, do not move. Then, convert the number from 1 to 1000 to a 10-bit long binary string, just one to one with 10 mice. Which of the binary numbers in a bottle is 1? Let the mice have something to drink. In the future, all the mice that have been drunk will be killed, but none of them will be killed. We will designate it as toxic!
