Very well. I'll give you some context.
Clause 10(2) reads:
(2) The Superintendent may (a) conduct studies, surveys and research programs and compile statistical and other information…
The word "may" is used here. The problem is that further on, it says that we must obtain the lowest price possible. So how can we obtain that information, namely, what the lowest possible price is, if the word "must", which would require the superintendent to provide it, isn't used? The word "may" indicates that it's optional.
