Question

Summarize the following by paraphrasing:
To retrieve the diamonds, the earth is crushed and concentrated. The concentrated material is then sorted by passing it over streams of water on greased tables. Since diamonds are water repellent, they will stick to the grease while the other minerals will absorb water and pass over the grease. The diamonds are then removed from the grease and cleaned, examined, sorted and graded.

• A. The diamonds may be separated from crushed earth by passing them through water flowing over a greased table. The diamonds adhere to the grease from which they are removed and cleaned.
• B. The diamonds are taken out of the crushed earth by passing them over a table that has grease on it. As they flow over the table through a water stream, they get attached to the grease and are later removed, cleaned, examined, sorted and graded.
• C. Diamonds get attached to grease and can be separated from crushed earth using water-grease systems.
• D. To get the diamonds, they are passed through water over greased tables to which they get attached. Later, they are removed from the grease and sorted.
