Which detail best demonstrates discourse between characters?excerpt from A Good Place for Maggieby Ofelia Dumas Lachtman"ACCIDENT AT GREENSTON NUCLEAR PLANT, No Danger to Community, Officials Say."Every time that headline from yesterday's Los Angeles News flashed into her mind, MargaritaMaggie-Cruz griped the steering wheel of herw more tightly and assured herself that she was doing the right thing. It wasn't as if she were in danger from the Greenston plant in the deserthundreds of miles away, but those headlines had been the convincing factor in her decision. Yes, it was the right thing to do, and hour after houras she drove north of Los Angeles, she had felt more and more competent and more secure. Until now.For the last hour she had been so intent on the changing countryside that she forgot to buy gas. The gauge said empty.

Gas isalmost twice as high up here as it is in Los Angeles. But I'm not complaining. When she had driven mile after mile without finding a gas station,she had begun to think that maybe being sixteen and a half didn't make her that smart, maybe a trip like this was a little much for her. Now shefelt better. She stretched and thought, Dad would be proud of me. I'm doing what is right for me. Oh, I'll miss my friends, especially Mim andLorena. I'll even miss Ryan.
