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: When did North Korea shut down its Punggye-ri nuclear test site? === The answer to the above question is

Question: WHITE HOUSE U.S. President Donald Trump on Friday met for 80 minutes in the Oval Office with a general he described as the second most powerful man in North Korea. Afterward, Trump told reporters on the White House South Lawn that the June 12 summit in Singapore between him and North Korea's leader, Kim Jong Un, was back on. Trump, however, sought to quell some of the high expectations, saying the summit would "be a beginning" and subsequent discussions were likely to be needed to get Pyongyang to agree to denuclearization. "We're not going to go in and sign something on June 12th, and we never were," he said. "We're going to start a process." Trump declared he "never said it happens in one meeting," but that it "will ultimately be a successful process." Asked by VOA News whether the North Koreans had committed to complete, verifiable and irreversible denuclearization, Trump replied only that "we talked about a lot of things." 'Take your time' The president said he told Kim Yong Chol, the former head of North Korean military intelligence, "Take your time. We can go fast. We can go slowly." The president made clear that sanctions on North Korea would not be lifted, however, until the country agreed to give up its nuclear arsenal. As the negotiations over the Singapore summit play out in public, there is a sense among some observers that Trump and Kim Jong Un each have a clear sense of the deal they ultimately want to strike. Less clear is whether the U.S. and North Korean visions can match up in any meaningful way. "Singapore might be the first time people will have to put their cards on the table," a U.S. official said on the condition of anonymity. Upon his arrival Friday at the White House, Kim Yong Chol, who is under U.S. sanctions for links to cyberattacks against American companies, delivered a letter from Kim Jong Un. While Trump did not reveal the contents, he described the gesture as "very nice." Question: Who delivered a letter from Kim Jong Un to the White House. === The answer to the above question is
OPTIONS:
- not enough information
- Kim Yong Chol
- Kim Jong Un delivered it himself
- A person from Singapore delivered it
Answer: Kim Yong Chol

Question: September 2006, and deep in the bowels of the Adam Street private members' club in London a very special group of people is crammed into a private room, supping imported Spanish beer from a free bar. The value - on paper at least - of the companies owned by those squeezed into this tiny, boiling space would dwarf the debt of a small African nation. Among those present are some of the key players in Europe's Internet industry. The content creators, the entrepreneurs, the inventors, the investors; these are the new media moguls. And tonight they're in their element. I'm hiding at the back of the room getting slowly drunk with the event's organiser, an entrepreneur who helped raise a ridiculous sum of money for a business networking site that had projected revenues of precisely zero. His mantra, he tells me, is 'revenue is the enemy'. It's not clear what that means, but I have to admit it sounds great. A microphone is being passed around and we're watching and listening as a succession of young - mostly under forty - men - they're mostly men - rattle off their CVs and their future plans. 'He,' whispers my drinking buddy, pointing the neck of his beer bottle at a short, well-groomed man wearing a yellow checked jacket and bright red trousers, 'was in the FT yesterday. Apparently BT are going to buy the company he co-founded for half a billion dollars.' 'Fuck,' I half-whisper back. One habit you soon pick up, hanging out with dot com entrepreneurs, is swearing. 'That's a terrible fit. It's like Friends Reunited* all over again. What the hell are BT going to do with them?' 'Nothing.' 'Nothing?' 'No, the story's bullshit. Totally made up. And they fucking printed it. ' 'Fuck.' 'Of course they printed it. They called the investors to check it out, but they refused to comment. So they ran it as a "rumour". And why not? It wouldn't exactly be the most outrageous deal of the year, would it?' He has a point. Question: How is the deal between BT and the new company going to go? === The answer to the above question is
OPTIONS:
- decent
- badly
- smoothly
- not enough information
Answer:
not enough information
