Write a question from the passage such that it identifies a character (a person or a thing) in the passage.

Input: Consider Input: It was a dream, then a place, then a memory. My father built it near the Suwannee River. I like to think it was in the heart of Florida, because it was, and is, in my heart. Its name was Dogland. Some people say you can know others if you know the central incidents that shaped their lives. But an incident is an island in time, and to know the effect of the island on those who land there, you must know something about the river they have traveled. And I must warn you before we begin, I don't know that river well. I visit that time and place like a ghost with poor vision and little memory. I look up the river and see fog rolling in. I look down the river, and the brightness of the approaching day blinds me. I see shapes moving behind me and beyond me, but who they are and what they do, I cannot say. I will tell what I know is true, and I will invent what I believe is true, and that, I think, is all you can ask any storyteller to do. I learned the Nix family history from the stories Pa told. Even at the age of four, I suspected that Pa's stories might not be perfectly true. When Pa said we Nixes came to North America as indentured servants working our way out of debtor's prison, Grandma Bette would make a face and say he couldn't know that. When he said we Nixes had Lakota and Ojibwe blood in our veins, Grandma Bette would say she wasn't prejudiced, but it simply wasn't so: she and Pa and his brothers and sisters were dark because her people were Black Dutch, from a part of Holland where everyone had black hair and black eyes. And then Grandma Bette wouldn't say a word for half an hour or more, a very long time for Grandma Bette to be quiet.

Output: Whose stories were not always true?

Input: Consider Input: "Looks good, Boys." Billy-Eye knew he had been taking a big chance leaving the final details for his sons to handle. He had not even visited the place all week. It was Friday, 5:30 PM--thirty minutes before the grand opening of Billy-Eye's Arcade and Dance Barn.
The arcade room had been arranged nicely--although not the way Billy-Eye would have done it. But still, it was good. The two popcorn machines were ready to go. High school aged workers were ready to hand out bags of the stuff. The first group in the competition was warming up on the bandstand. A stand-alone blackboard to the right side of the drums had the name of the band written across it in white chalk: The Triangulators. Each band would be responsible for putting their name on that board.
"Glad you like it, Daddy." Craig beamed. Finally, he had done something right.
"So, what do you think? Will we have a full house tonight?" said Billy-Eye.
"Sure," said Lenny with a naive smile.
"Hopefully," said Craig. "They get in free, get to hear eleven bands, and get all the free popcorn and coke they want. I'm sure the kids have heard our radio ad."
"Maybe we should have made the games free too," said Lenny.
"Hey, we can't give everything away," said Billy-Eye. "We're only charging a quarter for the games as it is." He walked back out into the main hall. "Is the refrigerator all stocked up?"
"Yes, Sir," said Craig. "It's loaded with frozen pizzas, hot dogs, and condiments. And we've got plenty of hot dogs buns and candy."
"And the soda fountains?"
"Ready to go."
"And I see you got the ice machine set up." Billy-Eye smiled. "Great. I'm proud of you boys."

Output: Who took a big chance on leaving the final details for hi sons to handle.

Input: Consider Input: U.S. President Donald Trump attempted to reset his relationship with Africa on Monday, as he hosted Nigerian President Muhammadu Buhari.
Buhari is the first sub-Saharan African leader to have a White House summit with Trump, who has been criticized for reportedly making derogatory comments about Africa.
During his public remarks with Buhari, Trump focused mostly on common goals and shared interests, such as fighting terrorism and expanding trade.
"We love helicopters he loves them more than I do," joked Trump, referring to his administration's decision to approve a $600 million military sales deal to Nigeria.
Buhari thanked Trump for approving the deal, which the administration of former President Barack Obama had suspended over allegations of human rights abuses.
"I worked it out so that now you can buy the helicopters that you want," Trump said, adding, "We make the best military equipment in the world, and our friends can now buy it."
Human rights groups have accused the Nigerian military of torture, rape and extrajudicial killing in its almost decade-long campaign against the Boko Haram extremist group.
Tens of thousands of people have been killed in the insurgency, and hundreds of schoolgirls kidnapped, as the group gained notoriety and spread to neighboring countries, posing one of the most severe threats to West Africa's Sahel region in recent years.
Although Nigeria has been a major partner in the U.S. fight against Islamist extremists in Africa, relations have faced challenges over the past year.
In January, Nigeria joined a list of outraged African countries demanding an explanation from the U.S. ambassador after Trump's reported vulgar comments referring to African countries.
Asked whether those comments came up during his private meeting with Trump, Buhari declined to comment.

"I'm very careful with what the press says about other than myself. I'm not sure about, you know, the validity or whether that allegation was true or not. So, the best thing for me is to keep quiet," Buhari said.
Output: Who is the Nigerian president?
