Answer:
Here's the answer to the best of my ability..
You're asking for what sentence is missing a hyphen and I see nothing wrong with the one sentence that doesn't have a hyphen.
But if you're asking for what sentence is using a hyphen incorrectly then option B is your answer because machine gun doesn't need a hyphen.
If you're asking which sentences are using the hyphen correctly then option's A, and C are your answer.
If you're the question you asked has no mistakes then the best answer would be option D because that's the only option without a hyphen.
Hope this helps.
The correct answer is that Alex and Joe have C. Contrary views of life.
This is because contrary means opposing, or opposite. Using the metaphor of the cherry, Alex believes that life is a bowl of cherries, meaning that he looks at life in a positive way. To Joe, life is "the pits", which means he is looking at life with a negative view. This shows the opposing, or contrary nature, of their beliefs, which shows you that the answer is C.
Hope this helps!
