Question

1. what do online simulators allow users to do?

a. only analyze data
b. perform manual calculations
c. conduct experiments with physical tools
d. conduct experiments and model scenarios using interactive digital interfaces

Explanation:

Online simulators are digital tools. They don't just analyze data (a is too limited). They are digital, so no physical tools (c is wrong). They automate, not manual (b is wrong). They use digital interfaces for experiments and modeling.

Answer:

d. Conduct experiments and model scenarios using interactive digital interfaces
