Question

I left out these two sentences. Thank you

1) Nature is first described as a magic element and then suddenly is turned into a dangerous creature.
2) Nature is moved by a Mighty Spirit, whose presence is manifest in every stone and tree.

Answer 1

Both sentences are fine.

Answer 2

I thought you might be interested in an article about English grammar in the workplace:

This passage explains and illustrates why you should ALWAYS include that serial comma before the conjunction:

<i>Tom Kamenick battled fellow attorneys at a Milwaukee, Wis., public-interest law firm over use of "the Oxford comma" — an additional comma placed before the "and" or "or" in a series of nouns [or phrases]. Leaving it out can change the meaning of a sentence, Mr. Kamenick says: The sentence, "The greatest influences in my life are my sisters, Oprah Winfrey and Madonna," means something different from the sentence, "The greatest influences in my life are my sisters, Oprah Winfrey, and Madonna," he says. (The first sentence implies the writer has two celebrity sisters; the second says the sisters and the stars are different individuals.) </i>
