I gave my students this multiple choice question: In a lab experiment, students are testing the identity of an unknown powder. Which method is most appropriate to move the powder to a balance?

Only one answer is correct among these 4 choices:
- sweep with a brush onto transfer paper
- scoop with lab spatula onto transfer paper
- pinch with fingers and lift onto transfer paper
- pour from bottle onto transfer paper

Could you tell me which one is correct?
