Given the task definition, example input & output, solve the new input case.
Write a question from the passage such that it identifies a character (a person or a thing) in the passage.
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.
Output: Who was abusive to the author?
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.

New input case for you: SINGAPORE Envoys from the United States and North Korea are holding talks to iron out any last-minute differences before Tuesday's historic summit between President Donald Trump and North Korean leader Kim Jong Un in Singapore.
White House press secretary Sarah Huckabee Sanders told reporters that veteran diplomat Sung Kim is leading the U.S. delegation in a working group meeting Monday at the city-state's Ritz Carlton hotel. The North Korea side is being led by Vice Foreign Minister Choe Son-hui.
Monday's meeting is apparently aimed at narrowing the gap between the U.S. and North Korea over the demand for North Korea to give up its nuclear weapons.
President Trump expressed confidence about his meeting upon his arrival in Singapore Sunday, telling reporters after stepping down from Air Force One that he his feeling "very good" about Tuesday's summit.
Ahead of his arrival, Trump acknowledged he is heading into "unknown territory" for the meeting Tuesday.
In response to a question from VOA News just before heading to Asia from the Group of Seven summit in Canada, Trump said "I really feel confident" about the unprecedented encounter between a sitting American president and a member of the family dynasty which has maintained iron-fist control over one of the world's most reclusive countries for three generations.
Trump added that he believes Kim, half the age of the American president, "wants to do something great for his people." But Trump cautioned that Kim "won't have that opportunity again" if the talks do not go well -- describing this opportunity for diplomacy with the United States as a "one-time shot."
Trump and others in his government have said advancement has been made on obtaining a commitment from Kim to give up all his nuclear weapons and long-range ballistic missiles. Progress could lead to a peace treaty and formally end a state of war on the Korean peninsula, which has persisted for nearly 70 years.
Whether such a deal can be done, Trump declared on Saturday, is something he will know almost from the moment they meet.
Output:
Who is leading the U.S. delegation at the Trump-Kim summit?
