the following rule will work in the vast majority of cases:
* if you are dealing with a word that
literally describes a numerical quantity (number, rate, height, length, volume, population, etc.), then you should use "
greater".
The population of Colombia is greater than that of Argentina --> correct
The population of Colombia is more than that of Argentina --> incorrect
* if you are dealing with a word that describes some
abstract characteristic of something (power, influence, effect, etc.), then you can use "
a/an + greater" or "
more" (the latter WITHOUT 'a/an').
John's father has had a greater influence on the development of his personality than has his mother. --> correct
The Prime Minister has more power than the King, even though the latter is the country's titular leader. --> correct
* if you are dealing with a word that describes
things that you can actually count, then you should use "
more".
I have more sports jerseys than anyone else I know --> correct
* if you are dealing with an
uncountable noun that is NOT a numerical quantity, then you should use "
more".
there is more furniture in this store than in the other one --> correct
Ram is greater than 6 feet tall
Ram is more than 6 feet tall
this should be the second one (or "over 6 feet tall"). this example may not conform to the rules above; however, it is unlikely to be tested on the gmat.
Ram's height is greater than Shyam's
Ram's height is more than Shyam's
height is a numerical quantity, so use "greater".
Ram's height is greater than 6 feet
Ram's height is more than 6 feet
height is a numerical quantity, so use "greater".
