Q27:TT-GWD 2-30
Most insomnia is not an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications, anxiety about travel, or stress before a job interview.

A. ！an illness or a physical condition so much as a symptom of another problem that may simply  be a reaction to certain medications
B. an illness or a physical condition so much as symptomatic of another problem that may be a simple one, like a reaction caused by certain medications
C. so much an illness or a physical condition but a symptom of another problem that may be as simple as when certain medications cause a reaction            
D. so much an illness or a physical condition, but it is a symptom of another problem, maybe a simple one like certain medications causing a reaction        
E. so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications                                    

19. GWD28-Q19:
Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface, where plankton live.  Nevertheless, some areas, though rich in these nitrogen compounds, have few plankton.  These areas have particularly low concentrations of iron, and oceanographers hypothesize that this shortage of iron prevents plankton from thriving.  However, an experimental release of iron compounds into one such area failed to produce a thriving plankton population, even though local iron concentrations increased immediately.
Which of the following, if true, argues most strongly against concluding, on the basis of the information above, that the oceanographers’ hypothesis is false?
A. Not all of the nitrogen compounds that are sometimes found in relatively high concentrations in the oceans are nutrients for plankton.
B. Certain areas of the ocean support an abundance of plankton despite having particularly low concentrations of iron.
C. The release of the iron compounds did not increase the supply of nitrogen compounds in the area.
D. ！A few days after the iron compounds were released, ocean currents displaced the iron-rich water from the surface.
E. The iron compounds released into the area occur naturally in areas of the ocean where plankton thrive.

Q19

question: argue against concluding the hypothesis (iron is important) is false.

Premise: 1) plankton thrives in areas with lots of nitrogen counpounds
             2) BUT, some areas, a lot of nitrogen compounds, not much plankton
             3) these areas have little iron, hypothesis that iron is important to plankton's living.
             4) an experimental release of iron failed to produce a thriving plankton population, even though local iron concentrations increased immediately


这道题的问题是：即便是这样的实验结果，也不能说哪个缺铁的假设是错误的。让你找一个支持假设的原因。

那么，就要找，如果有其他原因导致这些铁元素没有发挥想象中的作用，那么就能支持题目假设了。

a) irrelevant
b) weaken the hypothesis... hypothesis says iron is important. this answer weakens.
c) irrelevant. hypothesis is about iron and the survival of plankton
D) corrent. iron compounds were washed away and the temporary existance of iron compound cannot support the thriving of plankton. 如果铁元素长时间存在，或许就能是浮游生物生存。
E) support the hypothesis. prove iron is imporant

A. ！an illness or a physical condition so much as a symptom of another problem that may simply  be a reaction to certain medications
B. an illness or a physical condition so much as symptomatic of another problem that may be a simple one, like a reaction caused by certain medications
C. so much an illness or a physical condition but a symptom of another problem that may be as simple as when certain medications cause a reaction            
D. so much an illness or a physical condition, but it is a symptom of another problem, maybe a simple one like certain medications causing a reaction        
E. so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications  

E is corrent.

A) not so much.... as.......    answer choice used idiom incorrectly.
B) like is wrong. 举例 is such as
C) when certain medications cause a reaction , awkward and not parellel to the rest of the sentence. 3 noun phases should be in parellevel
D) "IT" is not clear, and like is wrong
