SEOUL North Korea shut down its Punggye-ri nuclear test site on Thursday to demonstrate its commitment to denuclearization in advance of the planned U.S.-North Korea summit. The development came hours before President Donald Trump called off the highly anticipated meeting. The South Korean government welcomed the North's unilateral nuclear concession to help facilitate a broader agreement with the United States to completely end its nuclear weapons program in exchange for ending punishing sanctions and security guarantees. "We are hoping that this action will become the opportunity for complete denuclearization in the future," South Korea Foreign Ministry spokesman Noh Kyu-duk said. However, while the closure of the nuclear test complex is a significant symbolic gesture, analysts are skeptical it will seriously inhibit the Kim Jong Un government's ability to carry out further nuclear tests in the future. "That renders the test site unusable, but not forever and it's not like North Korea has a shortage of mountains or people to make new tunnels," said Jeffrey Lewis, the director of the East Asia Nonproliferation Program at the Middlebury Institute of International Studies in California, during an interview with Vice News. North Korea conducted all six of its nuclear tests at the Punggye-ri underground site that includes at least two extensive tunnel systems, according the 38 North website that monitors the North's nuclear activities. Each nuclear test conducted at the site was progressively more powerful, with the first bomb detonated in 2006 producing an estimated 1-2 kiloton yield, much less powerful than the 16-kiloton bomb the United States used on Hiroshima during World War II, and the last test in 2017 producing close to a 250-kiloton yield. There were reports that the last nuclear test in September of 2017 triggered a tunnel collapse rendering the site unusable, but analysts say there were still two other tunnels that could be used for future tests. Earlier this year North Korean leader Kim Jong Un... Question: Probably how long was Jeffrey Lewis' interview with Vice News? === The answer to the above question is

Question: NOT A PROBLEM: Person A: I was really surprised to learn that your mum used to live in Wales. Person B: My mum? No, she never did that. You must be thinking of someone else. Person A: No, I'm not. I told her how my parents are from Cardiff and she said she'd lived in Newport until she was 18. Person B: She did not. Person A: Yes, she did. Person B: Nope. She'd have told me. Person A: Well, where do you think she grew up, then? Person B: In Yorkshire, of course. Like the rest of us. Person A: You're wrong, you know. Person B: Bet I'm not. Person A: OK, well, I'm going to phone her and ask her. You'll see. PROBLEM: Person C: You still have my Kindle. Person D: I do not. I gave it back to you two weeks ago. Person C: No, you didn't. You said you were going to, but you never actually gave it to me. Person D: I did. I remember. It was when we were having lunch in Starbucks. Person C: No, that's when you said you'd left it in your car and would get it when we'd finished eating but then you forgot all about it. Person D: Look, I gave it back to you. I think you're just trying to get a new Kindle out of me, and let me tell you: it ain't gonna work. Person C: You're just trying to keep my Kindle for yourself. Well, I'm not going to let you get away with it. I'm going to tell your mum, so there. It really depends whether the parents are in a position to shed any light on the contentious issue or if involving them would just make an awkward situation worse. If parental input will be helpful, welcome the chance to confer with them; if it won't, let the other person do what they will and trust your parents to have more sense than to get involved in a purely private argument. Question: What got left in the car === The answer to the above question is
OPTIONS:
- Lunch
- Mum

Question: SEOUL The annual U.S.South Korea joint military exercises currently underway have historically been a very public demonstration of force intended, in part, to counter North Korea's aggressive nuclear and missile tests. But with looming diplomatic summits aimed at reaching a deal to end the North's nuclear program, media coverage of the drills has so far been limited. This week, the U.S. Second Infantry Division held a public tree planting ceremony at Camp Casey in South Korea, near the inter-Korean border. "It is my belief that this tree, like those that have come before it, shall symbolize the roots that bind us together, and to our past in an enduring way," said General Jon Howerton, the deputy commander of the U.S. 2nd Infantry Division, at the event. The journalists attending the tree ceremony were also permitted to watch a shooting competition to determine the best marksmen in the participating U.S. and South Korean divisions. The Camp Casey event was one of the few joint military training activities that news organizations have, so far, been allowed to cover, and it illustrates how the United States and South Korea are downplaying the offensive component of this year's combined exercises. "This is clearly in order to send a signal to North Korea that South Korea and the United States are not willing to escalate the situation any further," said Go Myong-Hyun, a North Korea analyst with the Asan Institute for Policy Studies in Seoul. This year's Foal Eagle and Key Resolve combined military exercises are similar in scale to past drills, with more than 23,000 U.S. troops and 300,000 South Korean forces engaging in joint battlefield maneuvers, and responding to computer-simulated attacks from North Korea. But the start of the drills was delayed this year at South Korea's request to set a peaceful tone for the Pyeongchang Winter Olympics in the South and to facilitate the North's participation in the games. Question: What does South Korea's leader think of Donald Trump? === The answer to the above question is
OPTIONS:
- He's pompous
- not enough information
- He's funny
- He's trustworthy
Answer:
not enough information
