For the safety-conscious Swedish market, a United States manufacturer of desktop computers developed a special display screen that produces a much weaker electromagnetic field surrounding the user than do ordinary screens.Despite an advantage in this respect over its competitors,the manufacturer is introducing the screen into the United States market without advertising it as a safety improvement.
which of the following,if ture ,provides a raionale for the manufacturer's approach to advertising the screen in the United States.
b the manufacturer does not want its compeitiors to become aware of the means by which the company has achieved this advance in technology
d an emphasis on the comparative safety of the new screen would call into question the safety of the many screens the manufacturer has already sold in the United States
各位高手请指教,这两个选项我当时纠结了很久,b为什么不对呢? |
