Read the following paragraph along with the question and answer. Then, respond with whether the answer is correct.
Passage: Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video. 

Question: Based on the explanation in the article, why do you expect to happen with the water and oil?

Answer: That they won't combine easily

Is the answer correct? Respond with only "Yes" or "No" and no additional text.
Yes
No. The passage explains that differences in density cause some things to float in or sink. Based on this information, we would expect the oil to float
