A student observes dark clouds are surrounding the school and the grass on the playground is wet. The student reasons that it rained. Which scientific skill did the student use to determine that it rained?

A)Classification

B)Observation

C)Inference

D)Prediction

Is it c?

Good point. You are really thinking. :-) I have to agree that the student used inference!

it is inference i got it right

I can't choose two options. And it seems like the student did not observe that it rained, rather he/she observed the dark clouds and playground, right?

But the student observed the dark clouds and wet grass.

Yes, but the question asks about which skill the student used to determine that it rained.

Both B and C.

Thank you very much for your help!
