2, Why is society interested in your intelligence and schooling??

Essentially, intelligence and schooling show what they have studied and acquired and what they are interested in and give a clue what kind of person you are. It might be easy way to know who you are and to ascertain you are adapted to the situation. People guess that the higher levels of education they have, the more efficiently they can work, while If someone have low level of intelligence , they guss they wouldn't be adpated becasue he will not make use of the work, however I think the intelligence and schooling don't show everythings who you are, just one hint to know the person. In the socity of Japan people tend to look only thier schooling or intelligence and adopt to a job. they sometimes don't look thier personality or motivation. I think it is very unfair and intelligence is not only education and schooling.

3, Do you think intelligence is fixed at birth, or is it constantly changed??

I think almost all people's intelligence are constantly changed. I can consider some reasons. It will be effected by the environment, their live or the relationship with people will give respectively feeling or thinking and be many different knowleges, and also the interests or educations are accumulated and get suprior capacity. Their accumulated experiences or knowlege have thier intelligence grow up. Yet a few people have outstanding talent by nature, even they haven't made efforts. Even if we make efforts tremendously, we are inferior to them. They are inherited by their parents or ancestors, however we migh get the motivation to keep making efforts, its feeling can be one of the intelligence. I hope we are all equal.

8, What does being "street smart" mean??

I regard "street smart" as the ability to live efficiently and flexibility. They need to adapt to the situations fast case by case, solve a problem efficiently and think flexibility. To be a street smart, they need many knowleges. If they have many knowleges, they can reach a conclusion fast and even they don't solve the problem straight, they can find other way to solve it with many knowleges. Depending on the circumstance, they live counfortably, that is street smart.
