Minor wording fix

Minor wording fix: "answers to 'some' questions" instead of 'few'

>It will build an entire directory structure based on ~~the~~ current environment and ~~the~~ answers to ~~a few~~ **[some](http://www.differencebetween.com/difference-between-some-and-vs-a-few-in-english-grammar)** questions.
