Which of the following, if true, would tend to weaken most seriously the prediction of scientific secrecy described above? (A) Biotechnological research funded by industry has reached some conclusions that are of major scientific importance. (B) When the results of scientific research are kept secret, independent researchers are unable to build on those results. (C) Since the research priorities of biotechnology companies are not the same as those of academic insititutions, the financial support of research by such companies distorts the research agenda.
