"What are the three basic methods for the simple separation of molybdenum-copper ores?"
...
"What are the five key elements in the preparation of Pure Tungsten Compound?"
...
"The electric current of the Third Level electric eel and the current of Plasma Coil Maze Bug are respectively suitable for ionizing which types of metals?"
...
Ren Zhong answered each question one by one.
