Not really, and I'll try to explain why.
The correct answers to those questions as given *are* correct, insofar as
the common knowledge of the populus is concerned, and adding further
detail known only to a few is somewhat superfluous. Everyone knows what
the 'highest mountain' is and the definition of the phrase is commonly
accepted, therefore the answer *must* always be, for that majority of
people who neither know nor care about the added fine details given by
Mike, Mount Everest.
Education was once described to me as simply diminishing deception, and
the more I've thought about it over the intervening years, the more I
believe that statement to be true.
A couple of small for instances- when you're first taught numbers and
basic mathematics, you're told that there are no numbers lower than zero.
Later, you learn about negative numbers, information that was previously
withheld. When you're first taught about the atomic weights of elements,
you're taught that the weights are whole numbers usually consisting of
the number of protons and neutrons in the atom's nucleus.
Later on, you're told that, well actually they're not exactly whole
numbers.
Answers given to questions asked of kids in possession of such incomplete
knowledge are, however, accepted as correct, as allowance is made for the
amount of deception they are under at that stage in their education
process. Some answers which would be accepted as correct from an eight
year old might not be accepted as correct from a twenty-eight year old.
All Mike did was remove some of the deception from which we all suffer,
but didn't render the answer 'Mount Everest' in any way incorrect, given
the level of deception shared by all. Answers are accepted or rejected
according to the burden of deception under which a particular peer group
is labouring.
