Question: What is the difference in percentage between the product descriptions written in Arabic and Thai?
SQL: SELECT CAST(SUM(CASE WHEN T1.Name = 'Arabic' THEN 1 ELSE 0 END) AS REAL) * 100 / SUM(CASE WHEN T1.Name = 'Thai' THEN 1 ELSE 0 END) FROM Culture AS T1 INNER JOIN ProductModelProductDescriptionCulture AS T2 ON T1.CultureID = T2.CultureID
