Consider the image. This image depicts a piece of wood floating on water. Which statement accurately describes the density of the wood compared to water?

• The wood is denser than water, hence it is sinking.

• The wood is denser than water, hence it is floating.

• The wood is less dense than water, hence it is sinking.

• The wood is less dense than water, hence it is floating.

This question has two parts. First answer Part A, then answer Part B. Part A A student is observing mixtures. In cup 1, the student mixed sugar with water. In cup 2, the student mixed oil with water. Which statement is true?

• Cup 1 is a homogeneous mixture.

• Cup 2 is a homogeneous mixture.

• Cup 1 can be easily separated by filtration.

• Cup 2 can be easily separated by evaporation.
