CR1。遇到 public benefit的对价格不敏感的那题    請問是哪一題??

     2
  
忘了是GWD还是大全里面做过,说一种plantkon,专家觉得它缺甚么,后来有觉得缺iron
  
问解释还是甚么?原题反正,选
D
,好像是说iron补进去几天之后就被fresh water怎么了。。。等我翻翻再来补充

 我找到了,煩請確認

GWD-28-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.

D

觉得选A  谁有答案啊

我觉得问题问的是 

哪一项 反对  (the oceanographers’ hypothesis is false) 这个结论  也就是说 哪一项认为oceanographers’ hypothesis是成立的 或者说支持

数学中:一个委员在4个学校选4个老师,选2男2女的那题,答案应该是6,并不是36~请确认。

我手邊的答案為D, 海浪帶走鐵
            
造成鐵短缺

1。DS:the average speed a bird across a lake is 18mile/s ,问这个lake是不是less than 21 kilometer?

  1)it takes the bird less than 20minutes to across the lake

 2) it takes the bird less than 0.4hour to across the lake 

偶选E ,因为这个是我最后一题。。盯着看了十几分钟。。。背下来了。。題目有無kilometermile的換算阿?

2。一个triangle,三个角分别是X Y Z,问Y=?

  1)x-y=y-z 2)x>y  偶选A   答案以 y=(x+z)/2表達即可?

4。DS:number line,X在 y 和z的左边。。问XYZ是不是在X的左边?

  1)XY<0 2)XZ<0 偶选滴E  C,得出x<0,y>0,z>0 xyz<0 且確定在X左邊

7。 类似jj98.x2y是正整数,x^y>1000?1x>52y/x>4  偶碰到的是>900,然后1)X>10 2y/x>4 选A

想請問這題有無x=2, y是正整數的條件阿?條件一不是很怪嗎?都已經給出x=2,還給個X>10的條件,是否改成y>10阿??這樣選A即可

8。有一个图,五个部分的investment。。 加起来一共是100,000,问说把每个部分减少p percent 之后save了X,问p in terms of X?10^-3X  不解這題,有人可以解釋嗎?

抛物線y=mx^2+h是否跟Xintersect   1m<0 2h>0;   偶選C忘記該思路,還請知道者告知,謝謝

我也觉得是6,虽然不大懂,但是我列过可能性,只列得出六种
