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

Let me give you an example: I really struggle to feel bad for people who actively choose to be miserable and manipulative. I'm dorky and like to use little proverbs all the time. One of my favorites is this: "you can lead a horse to water, but you can't make him drink." At the end of the day, if someone has a problem, they can never resolve it if they don't truly wish to. You can give someone all the resources in the world, but you can't force them to utilize them. When I was 16, I dated a horrible guy. He was abusive verbally, emotionally, and sexually. He was an incredibly troubled young man and refused to seek help for his severe mental health issues. I eventually came to understand that he reveled in his misery. It was his identity. He acted like he wanted a cure and I'd set him up with resources, but he refused every single one. He may have struggled with serious mental illnesses, but being miserable perversely made him happy and he loved to use his struggles to justify his inexcusable behavior. He wanted to drag as many people into his fiery pit of anguish as possible. I later suffered from severe depression myself, and I never once used it as an excuse to hurt other people. My ex wasn't struggling with his mental health in terms of deliberating and carefully harming others. He was simply exhibiting a personality trait, one he chose to cultivate… and it wasn't my problem. I ended up cutting him off completely in spite of all the threats. I will never feel bad for the awful plight he refuses to help himself out of. I have no patience for that type of person. Know what we call them? Toxic. Poison. A waste of time.
The answer to this example can be: Who was abusive to the author?
Here is why: The question is based on the following sentences in the passage - 'When I was 16, I dated a horrible guy. He was abusive verbally, emotionally, and sexually.'. The sentence clearly explains that the author's boyfriend was abusive to her.

The violent ambush that killed five Dallas police officers and wounded seven more could have been a lot worse, the city's police chief says.
Dallas Chief of Police David Brown told CNN Sunday that the slain gunman told police negotiators he wanted to "kill white people, especially white officers."
Bomb making materials and a journal were found at Johnson's home during a search Friday.
"The material were such that it was large enough to have devastating effects throughout our city and our North Texas area," Brown said.
Micah Xavier Johnson, 25, was killed by police in the deadly attack Thursday night during a protest against police killings of African American men.
Since the shooting deaths of two black men by white police officers over two days last week, protests have been held across the country. Scores of demonstrators have been arrested, with one flash point being the southern city of Baton Rouge, Louisiana, where DeRay McKesson, one of the most prominent activists linked to the police reform protest movement Black Lives Matter, live streamed his own arrest.
Police defended his arrest as a matter of public safety, but demonstrators told U.S. news outlets they believe McKesson was targeted.
McKesson was freed on bond Sunday afternoon after being charged with obstructing a highway. "I remain disappointed in the Baton Rouge police, who continue to provoke protesters for peacefully protesting. There's a lot of work to be done, with this police department specifically,'' he said.
But Louisiana Governor John Bel Edwards disagreed with McKesson's assessment. The governor told a news conference Sunday that he is proud of the state's law enforcement officers, calling their response to the protests "moderate."
In the northern city of St. Paul, Minnesota, where a second man, Philando Castile, was shot to death last week by a policeman after a traffic stop for a broken tail light, hundreds of protesters hurled firecrackers, rocks and bottles at police on Saturday.
The heavily armed officers used smoke grenades and pepper spray to break up the demonstration, with about 100 arrests. Authorities said 27 police officers were injured in the clashes.
