Which of the following is evidence that Grandpa Bill had an external conflict? Jason picked up a model helicopter on his grandfather’s desk. “This is cool,” he said, spinning the blade on top. His grandfather walked over and took thehelicopter in his hand. He looked at it for a moment without saying a word. “It’s a Huey. I flew one just like it in Vietnam.” “You mean the Vietnam War, Grandpa Bill?” Jason asked. He knew his grandfather had fought in the war, but he never liked to talk about it. Grandpa Bill nodded. “The Huey was equipped with rockets and machine guns. Some of them even had grenade launchers.” Jason’s first instinct was to say that was cool. A helicopter with all those weapons would be amazing. But then he realized Grandpa Bill was a war veteran. The reason why he didn’t like to talk about the war was because it had been frightening. “Were you scared?” Jason asked, looking into Grandpa Bill’s eyes. “Of course. But I had a very important job in the Huey. I had to escort troops for the Army and Marines. The Huey became a symbol of the U. S. forces in Vietnam,” Grandpa Bill said, his voice quiet. “Some people say I’m a hero, but I’m not so sure.” Wiping a tear from his eye, he began telling Jason about his time in Vietnam.
