  Although initially symptomless, glaucoma can eventually cause blindness when not properly treated. Tests under laboratory conditions of the traditional treatment, daily administration of eyedrops, show it to be as effective in relieving the internal ocular pressure that causes glaucoma as is a new laser-surgical procedure. Yet glaucoma-related blindness occurs in a significantly smaller percentage of patients who have had the surgery than of patients for whom only the eyedrop treatment was prescribed.

  7. Which of following, if true, most helps to explain the low rate glaucoma-related blindness among patients who had the surgery?

  A. Glaucoma-related blindness is no more common among patients who have had only the surgery than it is among patients who had the surgery after using the eyedrops

  B. Doctors rarely recommend the surgery for glaucoma patients who have already started the traditional course of treatment

  C. There is no known physiological cause of glaucoma other than increase in pressure inside the eye

  D. A significant percentage of the people for whom the eyedrop treatment has been prescribed fail to follow the prescribed daily regimen, because the eyedrops have unpleasant side effects.

  E. The eyedrops traditionally prescribed to treat glaucoma are normally prescribed to treat other disease of the eye.

  文章第二句和第三句用yet呈现的矛盾是:实验室里面滴眼药水和做手术是一样有用的;但是现实生活中滴眼药水的人要惨一些。

  题目让解释为啥。解释类的题都需要针对矛盾来解释。D答案说实验室确实一样好,就是理论功效不错,但是很多人因为觉得滴眼药水不舒服就没有用,所以好东西发挥不出作用,所以出现了这个矛盾。

  填空

  Baker was struck by the amount of ______ she saw at the renowned medical facility; for all their experience, the physicians could not seem to agree on the correct diagnosis for any given patient.

  A. discordance B. contention C. quackery D. nepotism E. indecision F. cronyism

  分号后面说大家没有达成一致,所以前面就是很不同,选AB。indecision主要是说不能很快决定,很犹豫,跟AB不是一个意思。DF是一组词,但是是裙带主义的意思。

  数学

  1. A box at a yard sale contains 3 different china dinner sets, each consisting of 5 plates. A customer will randomly select 2 plates to check for defects. What is the probability that the 2 plates selected will be from the same dinner set?

  做法一:第一个无所谓,所以是100%;抽第二个的时候总的还剩14个,还有4个跟之前那个一样,所以是4/14=2/7。

  做法二:假定分成红色黄色蓝色三种,都抽到红色的概率是5/15*4/14,都抽到蓝色和黄色也是这样,所以再✖️3,所以是2/7。

  做法三:15个抽2个总的有15C2种;来自于同一套的要从每5个里面抽,所以是5C2,但有三套,所以是5C2*3。所以答案是5C2*3/15C2=2/7。

  2. Mike, Scott, Jim, Kate and Pete each have a different number of assignments this month. Pete has fewer assignments than Kate, Kate has more assignments than Mike, Mike has more assignments than Jim, and Jim has more assignments than Scott. Which of the following could be the person who has the median number of assignments this month for the five people listed?

  Indicate all such answers.

  A. Mike

  B. Scott

  C. Jim

  D. Kate

  E. Pete

  从小到大排,可以确定的是PK, SJMK这样的顺序。如果P最小,中位数是J。如果P向右移一个,中位数是J,如果再右移就是P,再右移就是M。所以只可能是JPM中的一个。答案是ACE。
