Survey Monkey is a multi-language portal; I suspect whoever created the survey entered on the French version. If you check the URL for the survey, after the https is a period then "fr", that part takes you to the French language version; if you exchange the "fr" with an "nl", it takes you to the Dutch language version of the same survey, "de" takes you to the German version etc etc etc. The content of the actual survey is in the language in which the person who created it used when he/she typed it in - it isn't that clever.
