• They are locked in place.

• They can move past one another.

• They move freely in all directions.

• They are locked in place, but can vibrate.

Maria is examining a straw in a glass of water. She observes that the straw appears bent when seen through the water from the side. What is the best explanation for this observation?

• Light is absorbed by the glass, causing the straw to appear bent.

• Light is reflected off the glass, causing the straw to appear bent.

• Light refracts when it enters the water, causing the straw to appear bent.

• Light is scattered when it enters the water, causing the straw to appear bent.
