| YOUR FINAL ANSWER should 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, do not use comma to write your number neither use units such as $ or percent sign unless specified otherwise. | |
| If you are asked for a string, do not 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. | |
| You have access to the following tools: | |
