I gave my students this multiple choice question: A student accidentally drops a test tube that breaks when it hits the floor. Which method is the best way to retrieve the broken glass?

Only one answer is correct among these 4 choices:
- pick up the pieces with a paper towel
- use a chemical spill kit
- use a dustpan and broom
- pick up the pieces by hand

Could you tell me which one is correct?

use a dustpan and broom
