SEOUL Arms control experts estimate that the dismantlement of North Korea's nuclear program could take a decade to complete, and cost $20 billion, if a nuclear agreement is reached between U.S. President Donald Trump and North Korean leader Kim Jong Un when they meet in Singapore on June 12. "The hard work has not yet begun, and it is gong to take sustained energy on the part of the United States, South Korea, Japan, China and North Korea. It's going to be a multiyear long process," said Daryl Kimball, the executive director of the Arms Control Association in Washington. President Trump has said he expects a "very positive result" from the North Korea nuclear summit, but he also said it will likely be the beginning of a process to resolve differences over the extent of the North's denuclearization, and the specifics regarding what sanctions relief, economic aid and security guarantees would be offered in return. U.S. Defense Secretary Jim Mattis said on Sunday that North Korea would only receive sanctions relief after it takes "verifiable and irreversible steps to denuclearization." This position aligns closer to the Kim government's stance that denuclearization measures and concessions be matched action for action. And it backs away from demands made by some in the president's national security team that Pyongyang quickly and unilaterally dismantle all its weapons of mass destruction before any concessions would be offered. North Korea is estimated to have 20 to 80 nuclear warheads, both known and covert nuclear research and processing sites, and thousands of ballistic missiles that can be launched from mobile vehicles, and submarine based launchers have been tested in recent years. With such an extensive nuclear arsenal it could cost $20 billion to achieve the U.S. goal of complete, irreversible, and verifiable nuclear dismantlement (CVID), according to a recent study conducted by Kwon Hyuk-chul, a Kookmin University professor of security strategy. Kwon based his assessment in part on past nuclear deals... According to the above context, choose the correct option to answer the following question. Question: Kwon Hyuk-chui probably believes Options: A. Thinks the deal is good for North Korea B. That it will be expensive for North Korea to denuclearize C. Thinks it was cheap for Ukraine to denuclearize D. not enough information

In recent weeks, the investigation into possible collusion between President Donald Trump's presidential campaign and Russia has intensified, raising the prospect that the probe could become an issue in advance of the November midterm congressional elections. Former Trump campaign manager Paul Manafort made another appearance in federal court in Washington Wednesday, where he pleaded not guilty to the latest round of charges brought by special counsel Robert Mueller. Last week, Rick Gates, Manafort's former deputy, pleaded guilty to lying to prosecutors and is now cooperating with the investigation. In mid-February, 13 Russians were indicted in connection with election meddling, which deputy attorney general Rod Rosenstein described as an effort to "promote discord in the United States and undermine public confidence in democracy. We must not allow them to succeed." Congressional inquiries also continue. Hope Hicks, the White House communications director and a longtime Trump aide, was the latest figure to testify before a congressional committee on the Russia probe. Hicks declined to answer some questions before a closed session of the House Intelligence Committee, frustrating several Democrats. "This is not executive privilege. This is executive stonewalling," said ranking committee Democrat Rep. Adam Schiff. But there was more pushback from the White House this week. President Trump fired off a series of tweets dismissing the probe as a "WITCH HUNT." "They have had this phony cloud over this administration, over our government," Trump told reporters at the White House last month. "And it has hurt our government, it does hurt our government. It is a Democrat hoax." Democrats reject that view, including Sen. Mark Warner, the top Democrat on the Senate Intelligence Committee. "I continue to believe that this is the most important thing that I will work on in my whole public career, and getting the whole truth out is extraordinarily important," he said. Warner's committee is also investigating possible... According to the above context, choose the correct option to answer the following question. Question: What issues were the Senate Intelligence Committee too exploring? Options: A. issues affecting the November midterm elections B. not enough information C. whether or not the probe was indeed a witch hunr D. whether or not there was collusion between Russia and President Trump

Once again, I've analysed my year of travel to see if I'm any closer to reducing it year on year. It's an annual habit, and if often kicks off new ideas that might affect my team's next year of work. The good answer is: yes, there is less travel! And not just that, but having reduced the schlepping I do, I've been able to hire more amazing people to lead on our work, and celebrate one of NoTosh's best years ever in terms of the quality, quantity and breadth of work we're doing. Key to traveling less has been a marked increase in the number of folk who see and are now reaping the value of working with us online. I've avoided as many as 20,000 miles of travel thanks to greener clients, who are also many dollars better off having not paid for the airmiles that are wrapped up in our regular fee structure. The quality of our work is better, too, thanks to this. We are doing fewer of those day-long workshops with teachers or leaders, when an hour or even thirty minutes before the day gets started is more worthwhile. We're seeing more school leaders take this up, although it's harder to get teachers into the habit of taking 30 minutes 'me time' to jump into a coaching session on the day or week ahead. But it's starting, and the value to us all is huge. Coaching is very different to 'consulting a Personal Learning Network' on Twitter. It's intense, targeted, focussed and involves a one-on-one discussion that arrives quickly at resolutions to current day challenges that will have a long-term impact. And we come back to measure whether that impact actually happened. I don't think it's a way of working that many are used to in Education, although many corporate clients have had some rare experience with it. Encouraging both groups to take more regular time out for coaching, little and often, is a real challenge, but we're beginning to see some huge impact from relatively little input (and relatively few dollars!). According to the above context, choose the correct option to answer the following question. Question: What do they do online Options: A. teach others B. They coach and help people C. encourage groups D. not enough information
