When providing multiple answers to a single questions QuestyCaptcha does not convert the answers to lower case, but it does convert the user input to lowercase which can make the question unanswerable. In contrast, when providing a single answer as a String, it is converted to lowercase as expected. Furthermore, the example at http://www.mediawiki.org/wiki/Extension:QuestyCaptcha#Question_and_Answer_Setup implies that you should be able to provide answers in upper case. It is mentioned in a comment in the QuestyCaptcha.php file that the answers should be lowercase but it is easy to miss.
Change 122104 had a related patch set uploaded by JustJustin: QuestyCaptcha ignore answer case when stored in an array https://gerrit.wikimedia.org/r/122104
