The given line graph represents the variation time taken to reach acidity level across three different sweet foods in the human mouth per 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 PH at 7 pH.
Post the first 3 minutes, the level of pH decreased for all sugar types and to a level below 5 pH, in which they enter the range in which decay can occur. By this time, cane sweet seemed to have the lowest level at around 3.7 pH. In the second interval, honey had experienced a stabilized trend, whereas cane and fruit exhibited increases in pH, at just above 4 pH and 5 pH respectively.
For the possibility of decay to not to occur with a level above of 5.5 pH, it is obvious that all the sweet foods had experienced two times of unlikelihood at the beginning and at another point later. However, for the first time occurrence, all types have converged to nearly below 3 minutes. For the second time of impossible decay to appear, cane had the shorter amount of time needed to be safe from decaying at about 13 minutes, followed by fruit food at 20 minutes. Ultimately, honey took the longest time to be unlikely to decay again at about 30 minutes.
