Fine clay is stirred into water and the water turns cloudy. What kind of mixture is this?

1. Cloudiness is the clue, because it shows that separate clumps are present. 2. The clay particles never dissolve, they stay spread through the water in clumps. 3. Those clumps block light, which is why the water looks cloudy and opaque. 4. A mixture of this kind is called a suspension. 5. A solution would look clear, because its particles spread out one by one. 6. Sugar stirred into water gives a solution, so that is the trap in this question. 7. Elements and compounds are pure substances and are not mixtures at all. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), A mixture of a solid and a liquid_
