AA: The soccer competition helpsthe increase in the number of tourisms, therefore the city should initiate otherinternational sport event for helping increase the tourisms visiting andeconomic development ( I paraphrase the argument, the original version isslightly different).
AI:  Business, more than the government organization,have the duty for society’s problems.
Reading
1.      China exclusion act in 1982 related to the restrictionof the immigration. This act has turn on hingeon the future immigration to USA. There is a question related to hinge, I chose“this is a small but critical factor…”
 
2.      P1: invisible particles in the universe

P2: what particles form the black object in the universe? It cannot be madeby neutrons and protons as they are too small… Neither can it be made byNeutrino, which is a too light weighted particle. Experiment indicated themovement of the Neutrino is very fast, so it cannot form clumps and therebyvery sluggish.

P3: People build a standard model to study the particles. It can beproved by theoretical approaches. The model is named as “symmetrical sth” (forgotthe name).

P4:Talk about this model. This model find a particle, named as Neutrinal, (whichhas similar properties as Neutrino, but Neutrinal is more stable and nointeraction with electronic magnify.
Logical reasoning
1.      Organic produce has fewer pesticides than theconventional products. Therefore, people eat healthier with organic produce.  In fact, people tend to eat excessive junkfood and less fruits and vegetables.  Askfor assumption: I chose People who buy organic products eat lots of junk foods…
2.      Not complete version:
City’shospital has a cost of 75% lower than other hospitals and its system is veryeffective. Therefore other hospital should also lower the cost. Ask weaken: Ichose The people who come to City’s hospital do not spend expensive medication…
Gummer:
Do remember the sentence, only theexaminable point:
1.      The use of dependent: should go with dependenton or dependent +none
2.      Of that
3.      Colon verse comma (exam question: …United States,as follow the reasoning or United States: reasoning without as—notice thechange from comma to colon).
Math
I don’t remember pretty much everything.
There is one question is asking the sum of a+b+c,given that absolute value of A+ absolute value of B + absolute value of C =a+2^0.5b+πC
Solve: Open each absolute value: -A+B+C, I chose 15.

那道数学题咋算啊...好抽象.
我就算出来B=2

gmatg2011

A= /4+2^0.5+3pi/, something like that, same for B=/.../ and C=/.../, I dont remember the exact number for this question, this is why I used A, B, C to represent three different absolute values. As for each absolute value, you can have two possible answers. To save your time, A=/../=-A (change the sign), B and C donot change the sign. So -A+B+C=a+2^0.5b+πc--you can then find value a, b, c. The sum of a+b+c=15 The other possibilities wont give you the answer listed in the question. Hope it makes sense.
