The given line graph represents the variation of acidity level caused by three different sweet food in human mouth per minutes within the period of 40 minutes.
At a glance, at the moment of eating any type of sweet food which are fruits, cane and honey had the same level of acidity at 7pH. In addition the graph pointed out two different time of decay occurrence for each sweet type at level of 5.5 pH.
Post the first 5 minutes, the level of pH decrease for all sugar type to level below 5 pH, where cane seemed to have the lowest level at around 3.7 pH. In the second interval, honey had experienced stabilized trend, whereas cane and fruit exhibited increases in pH, at just above 4pH and 5 PH respectively.
For the possibility of decay to occur with level of 5.5PH, it obvious that all the sweet food had experiences two times of likelihood at the beginning and at another point later. However, for the first time occurrent, all types have converged to nearly 5 minutes. For the second time of possible decay to appear, cane had the shorter amount of time needed to decay at about 13 minutes, followed by fruit food at 20 minutes. Ultimately, honey take the longest time to start decay again at about 30 minutes.
