RULES FOR QUOTATION MARKS USAGE:

• Direct Quotation:
  Place quotation marks before and after the exact words of a speaker or writer.
  Examples:
  The teacher said, "Did you do your homework?"
  "I know the answer," she said.
  "Eating and drinking," she said, "are not allowed in the library!"
  

• Indirect Quotations (no quotation marks needed)
  Indirect quotations are not the speaker's exact words. The word "that" is often a good clue that the words following are not being quoted exactly.
  Example: She said that she loved swimming.

• Use quotation marks to enclose the names of television shows, short poems, essays, short stories, and chapters from books.
  Example: Mark Twain wrote the novels "The Adventures of Huckleberry Finn" and "The Adventures of Tom Sawyer".

• Use quotation marks to emphasize sarcasm, irony, or humor.
  Example: Cigarettes don't kill; they "control the population growth!".

• Use single marks to enclose a quotation within a quotation.
  Example: She said, "The publisher called the novel 'a blockbuster' and wanted her to write a sequel."
