Below are sql tables schemas paired with instruction that describes a task. Using valid SQLite, write a response that appropriately completes the request for the provided tables. ### Instruction: What is the highest K 2 O, when Na 2 O is greater than 1.87, when Fe 2 O 3 is greater than 0.07, when Objects is Ritual Disk, and when Al 2 O 3 is less than 0.62? ### Input: CREATE TABLE table_7207 (
    "Objects" text,
    "Date" text,
    "SiO 2" real,
    "Al 2 O 3" real,
    "Fe 2 O 3" real,
    "K 2 O" real,
    "Na 2 O" real
) ### Response: SELECT MAX("K 2 O") FROM table_7207 WHERE "Na 2 O" > '1.87' AND "Fe 2 O 3" > '0.07' AND "Objects" = 'ritual disk' AND "Al 2 O 3" < '0.62'
