Read the following context and choose the correct option to answer the question. Context: 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: Why did the start of the drills get delayed this year? Options: A. Per North Korea's request B. not enough information C. The US wasn't ready D. To set a peaceful tone for the Pyeongchang Olympics

Read the following context and choose the correct option to 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: What is probably true about Trump? Options: A. not enough information B. he thinks this decision will help with diplomacy C. he thinks Kim Jong Un should comply D. he thinks President Moon can help

Read the following context and choose the correct option to answer the question. Context: For active people, regular training is as important part of maintaining and increasing fitness. About the only real downside to regular exercise is the transient toll it takes on the body after a hard training session. The pain and soreness after training needs sufficient time to recover from before another hard session can be performed. A very plausible theory pushed for many years is that the post-exercise oxidative stress in the body is the primary cause of the muscle damage and fatigue experienced. If you could reduce this oxidative stress, then it would allow quicker recovery, and then more time spent training. What this theory ignores though is that oxidative damage is a natural part of how the body adapts to stressful exercise, allowing the body to repair and grow stronger to allow higher levels of performance in the future. A small scale study has previously found that trained and untrained individuals who dose up on antioxidant supplements impair important exercise training adaptations such as improved insulin sensitivity and production of oxidative stress defence proteins. Now researchers have extended this study by looking at the effect of antioxidants in trained female runners, and published their findings in the European Journal of Sports Science. Twenty-three well trained female runners took part in three separate 3-week training blocks where they took either 1 gram of vitamin C, blackcurrant juice, or a placebo drink for each of the training blocks. Each of the dietary interventions involved drinking a similar volume of fruit drink of a total of half a litre per day split over the morning and evening. The training performance of each runner was carefully measured at the beginning and end of each 3-week treatment period. The runners stuck to a set training schedule which allowed a more accurate assessment of any changes in performance over the training period. Question: Trainers may believe that: Options: A. juice is a placebo B. not enough information C. you should train less D. antioxidants are now bad
