6 - "is." It is a message.

8 - "founded" is probably a better answer. Though if someone is looking through a place they don't know, maybe he found several cities. Hard call.

9 - you probably picked the best answer, but released would be ok, too.

10- answers 1 and 3 would be better.
#3 - dormant (sp)

#8 should be "founded"

Scroll down below the visual thesaurus chart, and read the verb definition under found2

#10 should be "astonished"
Re #3 --

I think the subject is plural! "Three dots, three dashes and three dots..."

Therefore, "are" is the correct verb.

(The word "message" is the predicate nominative, not the subject.)
