[转帖]3.27 North America JJ
A lot of Math Jijin, here is sth new:
1. what's the value of a2(Pingfang)B3(lifang)?
a. a(-2)*3(-3)=36(-1) (pingfang, lifang and -1fang)
b. ab(-1)=6(-1)
2. A string has 10 bulbs, if one bulb fail, all the other bulb will fail. The probability for one bulb to fail is 0.06, what's the probability for no bulb to fail?
a.0.06 b. 0.06(10) c. 0.94(10) d. 1-0.94(10)
Verbal:
AI: The most effective leader is who can maintain high ethinic standard
AA: More people take subway, so if the station reduce the fair of shuttle bus or raise parking fee, more people will take shuttle too.
Reading:
1. Black whole
2. Maxi theory
3. Woman's work did not count in the 18 century census. Long reading, very confusing.
2. The invention of Edison's disc casette and someone's gomosphone( a similar machine). Edison's has better sound, and Edison is famous, so his invention has some initial advantage. However, vector marketing make the latter one more popular by right marketing strategy. They use the famous opera singer for advertisement and thus appeal more to consumers. 35 lines, not hard.
Sorry, I can not remeber any critical reasoning or sentence correction. The critical reasoning is very long, about 5 lines per question, need to read fast and well.
Wish all XDJM good luck! |
