As said by Martin Luther king:" A lie cannot live."

Yes. That's good.

okay thanks Ms.Sue!

Change the colon to a comma, and it'll be perfect!

why wouldn't the colon be acceptable?

The part before the colon is not a complete sentence. It's a dependent (subordinate) clause.

oh I see it now thanks!

You're welcome!

Yes, you can start a sentence with "As." However, it is important to note that starting a sentence with "As" typically introduces a dependent clause, which needs to be followed by an independent clause to form a complete sentence.

Here's an example:

"As the sun started to set, the sky turned a brilliant shade of orange."

In this sentence, the dependent clause "As the sun started to set" is followed by the independent clause "the sky turned a brilliant shade of orange," which gives the complete meaning.

When beginning a sentence with "As," it's helpful to ensure that the structure and meaning of the sentence are clear and logical.
