9. Generally speaking, when you choose to buy or fall, it does fall, and then you will, er, gain profits.

10. The anticline is easy to collapse because of the tension of the anticline crust in the process of movement. The syncline is very tight and not easy to collapse
it must be easy to collapse near the fault
but it's just a Book saying that it's OK to cope with exams. In real life, there are many special situations, not necessarily syncline anticline, any situation is not good collapse. And although anticline oil and water storage performance is good, but no one is completely in accordance with the book said mining.
