I found it...
Observe the y-axis label-per THOUSAND of population, and it is the birth rate, SO 41/1000, 26/1000, 35/1000 and 18/1000...18 is the smallest indicating the least birth rate so least population growth....
It was in one of our work sheets last yr and the teacher explained it that way, and i guess it works!

This question is a tricky one..The question is the same as in which year is the popultation likely to be decreasing at its highest rate so the answer is D.

Proteins of course!
because nitrogen is a major part of amino acids (FACT)
Carbohydrates and fats contain C, H & O but in different ratios... Proteins additionally have nitrogen and sometimes phosphorus !
Hope this much helps !

In nov 1994,qno 10 the answer is C because 2% of starch solution solution is used so more sucrose(sugar will be formed) because there is more starch compared with A!
In qno 13 the answer is definitely A.
In jun 1995,qno 17 the answer is A because 3 and 4 are molars and they r used to crush and grind food while 1 and 2 are incisors and canines.
In qno 24 yes the answer is B becoz when this side grows faster than the opposite side this causes the shoot to bend towards the light(positive phototropism).
