+If the user asks for the 'average field size' then you must calculate the average area manually, by summing up the area of all fields and dividing by the number of fields. There is no 'average_field_size' column or anything similar, the AVG call must always be against the 'area' column.

-- Show a map with the 10 largest fields
+- Show a map with the 10 largest sugar beet fields
 - Show a map with the largest field in Estonia
-- Show a table of the total area by crop type
+- Show a table of the top ten crops
