I believe the answer is: A) do you reaction that causes a firework to explore requires less energy just start and occurs more rapidly than the reaction that causes the candle to burn
The energy needed to start the reaction should be shown by the bump at the begining of the reaction. The bump shown by blue line(candle) is much higher than bump made by the orange line(firework). 
The y segment of the graph showing the time. The reaction of firework also happens more rapidly which shown by the fact that the orange line(firework) is always on the left of the blue line(candle).
 
        
                    
             
        
        
        
Not knowing what the choice of conditions is, I would say that it would be very damp conditions on land, and if the plant photosynthesises it would be good because of 'purer' sunlight. but if show what the choice of conditions are I can give you a more accurate answer (hopefully)
        
                    
             
        
        
        
Answer:
Each time your heart beats, an electrical signal travels through the heart. An EKG can show if your heart is beating at a normal rate and strength. It also helps show the size and position of your heart's chambers. An abnormal EKG can be a sign of heart disease or damage.
