Question: I'm taking a test and have to guess the right answer to the question after the article. Article: I was driving home on a very hot afternoon and about to near a crossing . One of the major traffic light had gone out , and a police officer was standing in the middle of around twenty lanes of very busy traffic . The fact was that he had no hat or shade to shield him from the burning sun but , he was upbeat and doing a fabulous job . I saw a drugstore on the comer , and while I was there , I wanted so badly to get some water for the officer ! I had some hesitation , though , as it was a little out of my comfort zone to communicate with a stranger in this way . I discussed , struggled , left , drove part-way home , turned around , went back to the drugstore , got water , and then found myself thinking about how to hand it to him in the busy crossing . I knew that he might not be able to take it - he wouldn't have hands to hold it since he was busy making motions to direct the traffic - but I had to try . I drove into the crossing , rolled down my windows as I passed the officer , and gave him the bottle of water . Though he wasn't able to take the bottle , he broke into a smile and said , " Thank you . " I drove home , feeling better for having persisted . And I was even inspired to call the station that afternoon to make sure they knew what a great job he did that day . It felt good to spread the positivity , and it was the least I could do . Question: What is the main idea of the passage ? Options: A: It is a hard job to work as a traffic police officer B: Spreading the positivity can make the world more beautiful C: The government should find better ways to solve the heavy traffic . D: Trust is very important to make friends with a strange man .
