Just as a person is unable to answer all questions.  We cannot excpect a program to answer all questions.  If I ask someone "What time is it?"  And they answer "I don't know I don't have a watch."  I cannot assume they don't understand english.  If I ask "What color is this chip?"  and they reply "I don't know I cannot see the chip."  Again I cann assume they don't understand english.  Even if they answer a question wrong.  "How many feet are in a mile?"  and they answer "isn't there 12?"  I can't assume they don't understand english, they may just be english majors.   |
