数学很烂(其实从小就很烂...), call me a retard on math!!! Well, 48对于自己其实算正常 =P 大概因为烂, JJ的难题都没见什么,估计是老在低分区struggle... 1. Given 452*37*16, add 1 to which one of the 7 integers will increase the value of the product by less than 1000? 2. For a line in XY plain, given slope of the line -1/5 and the line passes through point (a,b) (a,b are constant numbers that I don't freaking remember...), what's the formula that best describes such line? 3. What is the value of the square root of a^2b^16((ac)^2)^-2? I think the answer was b^8c^-2.. 4. 2*10^5 + 1 is guaranteed to be divisible by which of the integers listed below? The choices were 2,3,4,5,6.... 不记得了... Verbal 也还算正常, 两次GMAT PREP 都是这个 range... CR: (This is what I remember in terms of content, NOT the original context...) 1. The Federal revenue anti-fraud department always gives one week notice before auditing a bank...then the argument says this is really bad because doing so will allow the bank time to cover up any fraud commission. Asked for assumption...the answer should be something like covering up won't make it even better for the Federal Dept to trace evidences of fraud. 2. Because of increasing crime rate, some dude suggests that high level police officer's salary should be linked to their performance in their respective as reflected by crime rate. If crime rate decreases, then the officer should get a pay raise, and vice versa. Asked to weaken...the answer should be something like it is impossible to calculate crime rates by a completely unbiased and independent officer. 3.Some company got 3 departments, one of them had a major employee cut, while the other two only employed a moderate number of employee, a number that was significantly less than that of the cut. However, overall the average pay of the company slightly increase. Asked which is best supported by this...the answer should be something like the average pay of the newly employed is higher than that of the cut 4.一道GWD-24-Q22的变体. Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-ray because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. X-rays of patients of many different orthopedists working in several hospitals were reviewed. Asked which was best supported by this...the answer was it was uncessary to order follow-up x-rays of ankle fracture initially judged stable. 5.In some place, gardeners there often dumb some weed to the river as gardening waste. The nutrition provided by the river is very damn good for the growth of such weed. The weed is expanding like crazy and choking a rare plant that resides also in the river. Therefore, gardeners should take the blame. Asked to weaken...answer should be something like a strong seasonal wind brought the weed to the river from somewhere far away.

RC: (Again, this is what I remember in terms of content, not the original context...) Evolution of horse.
Evolution of horse. Saying horses, unlike other animal such as squrril, change a lot from ancient days til modern.
Saying horses, unlike other animal such as squrril, change a lot from ancient days til modern. First, horses in ancient days used to live in forest and fed on leaves. Ice age came, most part of the forest was covered by ice sheet. Horses had to migrate to some plain where it was warm enough for grass to grow. So their diet changed from leaves to grass. But their metabolic system could not break down glutose in grass as effectively so they had to eat a whole lot and also their bodies became a lot bigger because the bigger the body is , the better it can store energy.

Second, horses' faces were lengthened for better chance of survival. The ancestor of horse used to feed on leaves but in the plain, when they were feeding on grass, their eyes were always blocked by surrounding tall grass and therefore they were unable to see pretators coming.
