no mate... u read the question rong... it was suposed 2 be the one tht lost the LEAST water ... 
didn't the question ask for the plant surface that loses the water most rapidly?
Yer, thats what I thought - so it must be the smalest bar?
Because if it lost a lot if water the paper would turn pink quickest...right?? 
Ya, but loss of water=absence of water
presence of water turns the chloride paper pink, which means the absence of water should 
not turn it pink, therefore the one tht took the 
most time 
lost water most rapidly... 
 
Hmmm....
