V1 说虽然雇佣临时工比雇佣全职的员工更加省钱，但是临时工的忠诚度没有全职员工的忠诚度高，但是有证据表明临时工的忠诚度是很高的，所以企业不会在解雇掉一部分正式工，雇佣临时工的同时面临着大规模的人员辞职。问assumption
辞退正式工，雇佣临时工的这件事，不会让那些没有被辞退的正式工想着要辞职
V2 有个公司准备用临时工来替换部分全职员工以降低成本。公司认为因为临时工的工作状态不比被替换的那些员工差，因此推断出换人后公司的总体工作状态并不会下降。问在evaluate这个论点时以下哪个选项必须被考虑。我只记得我选的那项了，即需要确认替换临时工是否会给公司里没被替换的全职员工的工作状态造成影响。
V3 企业打算把部分regular employees换成临时工，因为临时工和regular employees的效率没有差别，但是又担心会影响员工的loyalty。有人提出这种担心是多余的。问题是，以下哪项assumption是这个观点base的。我选的是：没有被replace的这部分regular employees不会由于部分regular employees被替换掉而失去忠心。
V4 有一家公司打算用temporary employees来取代部分permanent employees。有人质疑说temporary employees的loyalty比不上permanent employees，但是事实显示，new temporary employees are as loyal as these permanent employees they have replaced.结论是使用temporary employees不会使公司员工整体的loyalty下降。问增强。我选的是，被替换掉的这部分permanent employees的loyalty不比留下来的那部分permanent employees的loyalty差。作者: Bala 时间: 2010-10-29 13:36

GWD28-Q19原题 感谢chinamerica提供
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. (Answer)
E. The iron compounds released into the area occur naturally in areas of the ocean where plankton thrive.作者: Bala 时间: 2010-10-29 13:36
