Q: 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: Why was a set training schedule used in a study of training performance of runners? === The answer to the above question is
Answer: it allowed for a more accurate assessment of any changes

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: How could Kim help his country become very rich? === The answer to the above question is

A: Agree to the unilateral disarmament proposal offered by the US.

- a couple weeks
- not enough information Now, answer this question: He picked me up at my house, and after getting back on the main road he turned up the volume on the radio. "Why do you even listen to that stuff?" I asked. It was schlock-rock, simple and unadorned wailing backed by incessantly grating guitars. "I don't really know." "You don't actually like it, do you?" I knew he didn't; I knew what he preferred. His apartment walls were lined with recordings of classical, even archaic music, European folk instrumentals. Maybe rock, once in a while, but he had had something amplified and pitch-altered on every time we'd been together lately. "I think we listen to pop music to punish ourselves," he said. "An aural bed of nails to compensate for our sins." "Those sins being...?" "I don't know... sometimes, don't you ever get so sick of everything you just want to cram your ears full of garbage to spite it all?" This was not normal second-date dialogue, but Phillip and I had known each other for a long time. "It's like you'd rather inflict pain," he said, "like you want to inflict pain on yourself, just for pure spite against... the stuff around us." "You'd choke on garbage to get back at a culture who would do it for you anyway?" "Yeah, kind of. Does that make sense?" "In a very cliched, pop-psychology sort of way, yes." I turned down the volume, then shut the radio off entirely. "Don't you ever want to hurt like that?" he asked. "It's why you read some thriller instead of a classic, it's why you watch TV instead of reading a book, it's why you watch a sitcom instead of PBS, it's why you watch Family Guy instead of the Simpsons." (I might have snorted at this point.) "Because you have to do the bad thing." Question: Phillip and the narrator had known each other for: === The answer to the above question is
