Which two of the following sentences, if true, cast most doubt on the Dean's conclusion? A. The number of students majoring in physics at the undergraduate level has been increasing steadily over the years, a trend that is expected to continue. B. The number of students studying chemistry declined even before cutbacks in research funding were noted. C. Most postgraduate students of physics move to careers in computer science and engineering. D. The Dean's own university has recently increased the number of staff members teaching postgraduate physics. E. Most of the postgraduate students are not interested to pursue a career in basic physics research after their postgraduate study. ___
