Read and understand · 1/2How does WorldParticle represent materials?

Read the answer and explanation

As small particles. The first paragraph names the particle representation.

Clue: MIT described WorldParticle on November 9. The AI system can model how materials such as cloth and fluids move by representing them as small particles.

Read and understand · 2/2What are the reported results?

Read the answer and explanation

Computer simulations. The second paragraph explicitly calls them computer simulations.

Clue: Researchers used the same basic AI design across six types of physical behaviour. These are computer simulations, not new materials made by the system.

Grammar in this story: A method with by

by representing them as small particles

By + ing explains the method used to model movement; them refers to the materials.
