We are comparing "rate of increase", two static elements. A rate can be greater than another one but not faster. You can say that X increases faster than Y or that the speed of X is faster than the speed of Y but "rates" do not "move" in any directions. they are static. Hence, A, B and D are out. E is obviously comparing apples and oranges and only C stands out.
Good one Paul
I was wondering if rate of increase can be compared for its fastness !!
DE are out.
AB are out bcoz of the "fastness" comparison.
C is best.
Consider this : Rate of increase = a number
for eg. 1970's = 5%
1980's = 10%
These numbers can be related only numerically not for its fastness.
I'm crossing the bridge.........
