Read the following context and answer the question. Context: 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: Why is there a sense that Trump and Kim Jong Un have a clear idea of the deal they ultimately want to strike? Answer:
OPTIONS:
- not enough information

Answer: There is a sense among observers that they have a clear sense because of the urgency of the deal they want to strike.

Question: Read the following context and answer the question. Context: Out of boredom, two scientists from the New Contagious Diseases Research Centre devised themselves a new game. One day, as a result of the suspension of a research project dealing with a dynamically mutating vaccine following the pattern of the eyesocket flu bacillus, they had absolutely nothing to do until the end of the day, because the boss didn't order them to wash test-tubes. They decided to play a game of hockey under the microscope. For a puck they used one of the millions of experimental bacillus, and one-arm pincettes, which as it happened also resembled hockey sticks, served as sticks. The bacillus was not happy with it at all. It wanted to rest after an exhausting task involving vaccine discouragement, and these whitecoats here planned to put it to work yet again. And this time the work was much more labor-intensive and even more exhausting than before, but the condition and health of the tired bacillus not as good as in the times of youth, about two hours ago. The scientists got excited. On a microscope slide they etched a hockey rink with laser, agreed on the rules, connected the microscope's camera to the big screen display and played until the morning. They had to change pucks several times, but that was fine, they had millions of them in stock. The next day they didn't have anything to do either and they continued to play. They even invited other colleagues and the popularity of the game was so huge they could afford to play it in a championship system. Soon, the games were joined by the guys from the car-repair garage next door. They were tough opponents and even tougher fans - they took from the lab and carried away with them several flasks and some equipment, as it turned out - to set up their own game station in pit number 5. Question: The scientists decided to play hockey with: Answer:
OPTIONS:
- The bottle cap
- not enough information
- A trash can
- The bacillus
Answer: The bacillus

Question: Read the following context and answer the question. Context: SEOUL North Korea's recent threat to pull out of the upcoming nuclear summit with the U.S. has added new urgency to South Korean President Moon Jae-in's visit to Washington next Tuesday. President Moon has played a key role in facilitating the meeting between North Korean leader Kim Jong Un and U.S. President Donald Trump scheduled to be held in Singapore June 12. At the recent inter-Korean summit Moon got Kim to affirm a broad commitment to rid the Korean Peninsula of nuclear weapons and that opened the door for Trump and Kim to negotiate a more detailed agreement to end North Korea's nuclear program. However, uncompromising positions recently voiced by U.S. National Security Adviser John Bolton demanding the North's unilateral disarmament, and by North Korea in response canceling further talks with the South and threatening to pull out of the U.S.-North Korea summit, have put the prospects for continued diplomatic progress in jeopardy. President Trump has tried to reassure the North Korean leadership that a nuclear deal would not weaken the Kim government, but would bolster it. "He'd be in his country, he'd be running his country. His country would be very rich." Trump said Thursday while meeting with NATO Secretary General Jens Stoltenberg in the White House. President Moon, who will meet with Trump in Washington on Tuesday, has said he will try to moderate differences between the U.S. and North Korea over how to achieve denuclearization, while also giving the Kim government the security guarantees and sanctions relief it wants. But the convergence of interests that have brought Moon, Trump and Kim to all agree to give diplomacy a chance seems to be diverging over how to bridge the gap between the U.S. demand for complete denuclearization prior to offering any concessions, and the North's insistence on a step by step process that would ease sanctions early on for incremental measures, such as giving up some nuclear material and allowing in outside inspectors. Question: Who recently threatened to pull out of the upcoming nuclear summit? Answer:
OPTIONS:
- the US
- North Korea
- South Korea
- not enough information
Answer:
North Korea
