You can substitute the word "many" for "myriad"
-- you'd never say "a many of ".)

has finished his

correct answer is Mozart
and Beethoven, who were in the
Classical Age (more streamlined music -- 1750-1820.)

worked hard to incorporate emotion in the
music -- 1820-1900.)

Science
Cooks routinely add
salt to water to make it boil faster -- actually
adding salt RAISES the boiling point, unless
you add a LOT of salt -- in which case, you've
actually reduced the amount of water (which
takes a lot of energy to boil) and increased
the amount of dissolved salt (which boils
at a much lower temperature.)
Learn
the nitty gritty on boiling water and salt.
Civics
A "chad" is the tiny
block of paper that is punched out when a
voter is using a punch-card ballot.
A "hanging chad" is one that does not entirely
drop off, and therefore might be a mistake.
We're not going to give you a link on this
one, since we've all heard far more about
hanging chads in the 2000 election than we
ever want to admit!
Computer
Science
It's hard to believe
that the Internet has been with us for only
about a decade! The original idea of
a World Wide Web was proposed by Tim Berners-Lee
and Robert Cailliau, who worked at CERT European
Lab for Particle Physics in Switzerland, in
1990. But before it could all
come together, they still had to create a
web browser, HTML language, and URLs (Universal
Resource Locators) so that we'd all be able
to find the sites that were not yet even dreamed
of.
