　　教授认为Advantages of EAS (Essential Air Service program) are not convicting at all. The subsidy should be eliminated or, at least, be reformed.

In some area, such as South Africa and Australia, the green agriculture did not appear until recently, but people live there experienced a decrease of brain size too.
