补发一個有很多人看不懂的怪題

july_0112

M1. the number 50，60and 70, weighted arithmetic mean as w1, w2 and w3 respectively, the sum of them is 1, the mean is less than 60, which of the following is true?

I. w1> w3
II. w1< w3
III. w2=0

A. I
B. II
C. III
D. I and III
E. II and III

這題出現在第十五左右, 懷疑是測試題.  因為有人第一題就碰上了.  我M50, 所有可能我之前連錯3題以上.  Anyway, 我當時也看不懂.  現在覺得它是在說:
w1+w2+w3=1 and
(50*w1+60*w2+70*w3)/3<60
如果我的想法是對的話, 選A.

SC
V1. ...who has no time and patient [劃線]
A. to get screened by [someone/something]
B. to get screening by [someone/something]
C. screening by [someone/something]
D. for screening by [someone/something]
應該是D, 因為no time跟for v-ing/to do [something].  可是我覺得to get screened太口語.  to get screening不如用for screening

V2. 全劃線: Led by [a person], a discovery...
簡單: 是一個team被led by [a person], 不是discovery.  這題看邏輯主語加which不可以指句子, 要用discovery.

V3. [劃線], the X and the Y villages...(大慨)
A. When compared to the A and the B tribes(大慨)
B. Compared to those of the A and the B tribes(大慨)
C. Compared to that of the A and the B tribes(大慨)

廷sure的: villages不能跟tribes比...that不能指複數

CR:
剛看KFC, 能記得的KFC上都有.

RC: 剛看KFC,都有

=============================================

後記:
考得不好, 雖然對我的SCs and CRs的答案廷確定(由其是CR因為考完後才發現KFC上有原題...sigh).
可是本人RC不好(GWD的RC的accuracy只有55%左右).  不覺得考題變難(本人的2戰) or 變奇怪.  可是有可能GMAC改了算分的方法.  Anyway, 只是guessing.
tips: RC一定要對位, 我考時候沒有耐性去對位因為想save time for難題(太貪心)..結果最後4題還有17分鐘...
還沒想要不要再戰...太累啦...
