Hello. You forgot to show the quote to which the text refers, the quote is:
"Ahhh" the crownd went, "ahhh," as at the most beautiful of fireworks, for the sky was alive now, onde instant a pond and at the next a womb of new turns: "Ahhh," went the crownd, "ahhh!"
Answer and Explanation:
The lake presents a calm and peaceful environment, without many elements and turbulences, in contrast to a water that is full of elements, twists and mysteries. When the author shows that the sky in an instant was in a lake and in the other a uterus, he shows that in an instant the sky was calm and placid, but afterwards, it was filled with admirable presentations, causing movement, admiration, curiosity and interpretation, as a uterus.
