Junior biomedical researchers have long assumed that their hirings and promotions depend significantly on the amount of their published work. eople responsible for making hiring and promotion decisions in the biomedical research field, however, are influenced much more by the overall impact that a candidate's scientific publications have on his or her field than by the number of those publications. The information above, if accurate, argues most strongly against which of the following claims? A. Even biomedical researchers who are just beginning their careers are expected already to have published articles of major significance to the field. B. Contributions to the field of biomedical research are generally considered to be significant only if the work is published. C. The potential scientific importance of not-yet-published work is sometimes taken into account in decisions regarding the hiring or promotion of biomedical researchers. D. People responsible for hiring or promoting biomedical researchers can reasonably be expected to make a fair assessment of the overall impact of a candidate's publications on his or her field. E. Biomedical researchers can substantially increase their chances of promotion by fragmenting their research findings so that they are published in several journals instead of one.
[机经17] 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.
