Professor: A marine biologist argues that transmission of sea lice from farm salmon to wild salmon is unlikely in the Broughton Archipelago, British Columbia, citing numerous studies suggesting that salinities less than 30 parts per thousand are unfavorable to sea-lice survival. The biologist concludes that the archipelago's 25-30 parts per thousand salinity range between March and June, the critical period for wild salmon migration, tends to suppress sea-lice proliferation. But a review of the literature shows that salinities of 25-30 parts per thousand in combination with British Columbia's cool spring temperatures favor the flourishing of sea lice. In this passage, the professor attempts to undermine the biologist's argument by
  • Apointing out that a condition claimed to be necessary for sea-lice survival is not sufficient for it 分析该选项
  • Bciting studies that suggest that salinity levels were not measured reliably 分析该选项
  • Cclaiming that there is evidence showing that one of its premises is false 分析该选项
  • Dquestioning the reliability of the biologist's scientific sources 分析该选项
  • Eshowing that its conclusion is inconsistent with its premises 分析该选项
