Freezing point is defined as the temperature needed for a liquid to turn into a solid and a melting point is the temperature needed for a solid to become a liquid. Sodium Chloride has a lower freezing point than water, as such when it is added to icy roads it helps to melt the ice faster by lowering the melting point of the water making it turn into a liquid faster/easier even if it is "cold" outside.

When might it be preferable to use direct quotations rather than summarizing or paraphrasing
Drupady [299]

Answer:

It is better to use direct quotation rather than summarizing or paraphrasing when you want to share the author's original words.

Explanation:

In writing, it is sometimes necessary to share an authors original words in order to buttress a point or validate an argument. In such cases where it is necessary to use exactly the same diction as the author in order to communicate a point clearly, it is apt to use a direct quotation rather than attempting to summarize or paraphrase the original words of the author.

Hence direct quotation is used to share an author's original words.
