Glad you found that - my recollection was that the entirety of the ballot question had to do with the Proposition 2-1/2 Override, but I wasn't sure, so I didn't want to post and be wrong.

For those not sure what that means:
Wikipedia has a good summary (https://en.wikipedia.org/wiki/Proposition_2%C2%BD) and if you really want the nitty-gritty then the D.O.R. has a primer for officials to understand it (http://www.mass.gov/dor/docs/dls/publ/misc/levylimits.pdf).
