The advantage of simulations is that they allow students to learn about a subject ______.

Correct answer: From the inside. Simulations place students inside a realistic situation, so they experience a subject from the inside.

• From outside: Learning from outside describes passive observation, not simulation.
• From the help of pens: Using pens is unrelated to the advantage of simulation.
• None of these: “None of these” is incorrect because learning from the inside is correct.
