Not Abe, Teddy, or Jack 
23A  
College concentration   MAJOR
7D   
23-Across opposite   MINOR [How do we read this clue?  In general, minor is opposite of major.  But a college minor is not 
opposite to a college major; they are adjuncts.  (In music, the major and minor scales are opposite because there are only two choices.  Men and women are opposites for the same reason.)  So, are the 
words in the grid to be compared, or what the words mean in the context of the clue?  If it is the the former, this clue is fine; if the latter, this clue is imprecise.]
