I believe the answer is B. You can communicate your emotions more easily. I hope this helps. I'm sorry if this is not correct. :)
Answer and Explanation:
The part of the sentence that includes a subject is "earn a great deal of money", as it shows that the sentence will talk about money and ways to earn it.
The part of the sentence that tells what happened to the guy is "the past 50 years cost more than expected," because it shows that host cities spent a lot of money even though they won large amounts of money from the Olympics. We can see this, because the subject of the sentence is "host cities".
The part of the sentence that says something positive about the games is "host cities earn a great deal of money," as it shows that there is an economic gain for the cities that host these games.
