Input: Read this: The years following 2009 marked a shift in the structure of the "Big Four" with Tottenham Hotspur and Manchester City both breaking into the top four. In the 200910 season, Tottenham finished fourth and became the first team to break the top four since Everton in 2005.

Input: Read this: During the summer growing season, phosphate is at a high level. It has a vital role in the breakdown of the sugars manufactured by chlorophyll. But in the fall, phosphate, along with the other chemicals and nutrients, moves out of the leaf into the stem of the plant. When this happens, the sugar-breakdown process changes, leading to the production of anthocyanin pigments. The brighter the light during this period, the greater the production of anthocyanins and the more brilliant the resulting color display. When the days of autumn are bright and cool, and the nights are chilly but not freezing, the brightest colorations usually develop.
Question: What does the chloropyll breakdown process lead to?

Output: unanswerable
