half as many the same number twice as many an unpredictable number
I gave my students this multiple choice question: Mitosis occurs in living things when a cell divides to produce two cells. Compared to the original cell, how many chromosomes are in each of the resulting cells?

Only one answer is correct among these 4 choices:
- half as many
- the same number
- twice as many
- an unpredictable number

Could you tell me which one is correct?

the same number
