Derek won this year's school science fair and is a star on both the school's football and basketball teams. Outside of school, he runs his own successful business and is an accomplished musician. Obviously, Derek is good at everything he does. Therefore, he will undoubtedly make an excellent Student Government President if elected.
The argument above is suspect, because it overlooks the possibility that
A. Derek participates only in those activities at which he knows he will excel.
B. being Student Government President requires different skills than those needed to become an accomplished musician.
C. school, sports, music and business are the only activities in which Derek is engaged.
D. there may be other students who are just as qualified as Derek to be Student Government President.
E. Derek has no time in his schedule to devote to Student Government.
