Yes, you can install both my REGEXP and Oleg Sychev's Perl-compatible regular expression question side by side (on a Moodle 1.9 site).
If you want to follow Oleg's developement or ask him questions, please go to this tracker discussion: CONTRIB-2234
or this documentation pages discussion:

the reason for the 4 incorrect alternative answers below:
a the quiet revolution.
a the quiet revolution
a the quiet revolution.
a the quiet revolution
it that your expression: (|a )(|the ) ?quiet revolution\.?/i
accepts the words "a" and "the" as being either both absent, or one present and the other absent or both present!
My suggested expression (a |the )? accepts those words as being either both absent, or one present, which is the desired result.
I would remove the optional full stop, since it does not make sense to have a full stop at the end of a "sentence" which does not begin with a capital letter.
"Is there a chance of a variation sometime that simple scans a string and if it finds the desired items, it accepts it no matter what else is there?"
No. This goes against the principles I have set in my REGEXP question type. Such a feature might allow for totally unwanted words to be present in a student's answer.
Maybe what you want could be achieved using the other question type also based on regular expressions: Perl-compatible regular expression question by Oleg Sychev.

PS.- No, your regular expression is not correct : ([a|A])?([Tt]he)? ?[Qq]uiet [Rr]evolution\.? Have you actually tried it in the Preview question mode, and clicked the Show Alternatives button? Here is a correct one:
(a |the )?quiet revolution/i
would accept:
a quiet revolution
the quiet revolution
quiet revolution
and any case (capitals) variation (A Quiet Revolution, A quite revolution etc)
the /i parameter at the end means "ignore case"
Please note that there have been a number of changes in REGEXP for Moodle 2.0. See the documentation and look for the "Moodle 2.0" labels in the right margin!
@Jeff If you had clearly said so in your original post it would have saved us time.
@ Tim this is not a theme issue, that table is left-aligned in all themes in Moodle 2.0.
I am personally very much against centered elements, of which there are too many to my taste in Moodle. It lends certain pages a jagged "Christmas tree" appearance. Apart from what are obviously "title" elements, everything should be left-aligned (or right-aligned for RTL languages, of course).
However, for the sake of those "center-aligned elements" fans, including the OP, here is a CSS rule to add to your current theme which will do the trick. Please carefully copy, minding the exact blanks.
#page-mod-quiz-view .generaltable.quizattemptsummary {margin-left:auto;margin-right:auto;}
attached screenshots (using the Fusion theme) (1) before applying CSS rule (2) after applying it (table is centered)
