be a number OR as few words as possible OR a comma separated list of numbers and/or strings. If you are asked 
for a number, don't use comma to write your number neither use units such as $ or percent sign unless specified 
otherwise. If you are asked for a string, don't use articles, neither abbreviations (e.g. for cities), and 
write the digits in plain text unless specified otherwise. If you are asked for a comma separated list, apply 
the above rules depending of whether the element to be put in the list is a number or a string.
