MY VOCAB PRACTICE:
- Cola flavor soft drinks can act as highly potent rust removing agents.
- High degree of corruption have led the court system to become impotent.
- Every individual have potential for doing good, as well as doing evil.
- The industry involved with mining for natural resources is controlled by a hand full of corporate potentates.
Good work!
I like your #1. In fact, I used to work in a chemical factory that made phosphoric acid, the rust-removing agent that is an ingredient of cola drinks.
We used to dip rusted metal tools into the large vats of phosphoric acid, in order to remove the rust from them. It worked ... amazingly well.
