Answers and Explanations

1.

When the letter "l" ends one word and begins another in a compound, a hyphen separates the words to improve readability.

3.

Correct : The afterimage slowly faded away.

"Afterimage" is correctly closed in this sentence.

4.
Original: Mary sighed in frustration as she endured another slow down during her drive to work.
Correct : Mary sighed in frustration as she endured another slowdown during her drive to work.

"Slow down" is open as a verb phrase (as in "I decided to slow down"), but in this sentence, "slowdown" is a noun and should be closed.

5.
Original: I assure you that it was a one time occurrence.
Correct : I assure you that it was a onetime occurrence.

"Onetime" is closed both in the sense of "occurring in the past" and "occurring only one time."
