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: How long did it take to shut down the nuclear testing site?

Patch's mother was named Silver, because high summer sun made her fur shine that colour. She had a marvellous drey high up a spruce tree, carved out long ago by a woodpecker, and since extended into a two-chambered home full of bright things. The journey along the sky-road to her drey did not take long. When Patch looked inside, he saw a hundred colours glittering in the sunlight, shining from bits of metal and glass set into Silver's walls and floor. But his mother was not there. He could tell by the faintness of her smell that no squirrel had been here in some time. There were two faint traces of scent, several days old; that of Silver, and that of another squirrel, a musky scent that Patch did not recognize. A scent that made his tail stiffen as if danger was near. Patch stared into his mother's empty drey for a moment. It wasn't normal for a squirrel to abandon her drey for days, not in the middle of winter. And he hadn't seen Silver for three days. Not since all the acorns had disappeared from the earth. Patch ran back to his own tree, and then to the maple tree next door, to his brother Tuft's drey. He ran very fast. He was hungrier than ever, and he was beginning to be very worried. He was relieved when he looked into Tuft's drey and found it occupied. Tuft himself was not present, but Brighteyes was, and their babies, and it was clear from the smells that Tuft had only just departed. "Hello, Patch," Brighteyes said weakly. "Would you like to come in?" Patch entered. Brighteyes was curled up with her babies in the drey's deepest, warmest corner. The last time Patch had visited, a week ago, this had been a den of noise and chaos, with all Brighteyes' four babies running and jumping and playfighting. Today they lay weakly beside Brighteyes, and the once-shining eyes from which their mother had taken her name were dim and clouded. Question: After visiting his mother's drey, who did Patch speak to? Options: A. His mother. B. Brighteyes. C. not enough information D. His brother. === The correct answer is
(A).

When I first started out in the field, I was working at a private hospital in the locked psychiatric unit, and there was a call from one of the med floors requiring someone from our unit to assist with a problem of a young man who had bitten through his cotton restraints on his wrists. They were requesting he be restrained with leather ones. I had not done any restraining and was asked to assist a woman counselor to show me the ropes (no pun intended). When we arrived in the patients room, I was shocked to see a man in his early 20's flailing around spasmodically on the bed with his gums bleeding in between his teeth. The nurse informed us that the patient was dying of a liver disease and his body and brain had become toxic, causing delirium. The counselor instructed me to hold down his arms and she placed him in leather restraints which were fastened to the side of the bed. The most upsetting thing which to this day I can not remove from memory was this man literally snapping his jaws at me like a mad animal with traumatized bloody gums from biting so hard on the cloth restraints. There was nothing I, or anyone could do, except keep him restrained from hurting himself or others. It is the kind of witness to suffering I had never experienced before, and I felt almost relieved when the nurse quietly said, " He will die before morning. " I suppose what is so traumatic about witnessing such situations is the utter sense of helplessness. I was a trained therapist, and in this situation, I was unable to do anything, and was rendered powerless. I recall being plagued by this young man's face for some time when I tried to go to sleep at night. Bruce Kugler Question: When did the patient finally succumb to the disease?
