Weight gain is a complex issue. But there is little doubt that the current food environment in Western countries heavy in highly processed salty, sugary, and fatty food has a big role to play. Most of the salt eaten in our diet has been added to food in the manufacturing process. This is in contrast to the small amount of salt naturally present in most foods or what is added at the table or at home in cooking. Salt can be a desirable taste, increasing the palatability of foods in addition to helping preserve it; that's why it is commonly added in processed foods. Combining salt and fat together is thought to be a potent combination in helping to promote passive over-consumption foods. Just think of how moreish salty chips can be. Having a greater liking for salty and fatty foods is associated with eating more kilojoules overall, uncontrolled eating, and overweight in children. This link between overconsumption of food and its degree of saltiness is considered stronger than having a liking for sweet and fatty foods. Teasing out further how salt may influence the over-consumption of fatty foods, sensory researchers from Deakin University recruited 48 healthy adults to take part in a tasting panel. Over four lunchtime sessions (following on from a standardised breakfast that morning), each person ate a meal of macaroni and cheese where the fat and salt content had been manipulated. The four meal combinations were low-fat/low-salt, low-fat/high-salt, high-fat/low-salt and high-fat/high-salt. Participants were encouraged to eat as much as they wished until feeling full. Eating rate, meal agreeability, and subjective ratings of hunger and fullness were also taken. Salt promotes over-eating Eleven percent more kilojoules were consumed when the meals eaten were high in salt. And this was irrespective of if the fat content was high or low. The fat content of the meal didn't result in people eating more food by weight, but because of its greater energy density, that meant more kilojoules were eaten. According to the above context, choose the correct option to answer the following question. Question: Who has the most unhealthy food: Options: A. Mexico B. not enough information C. America D. China

Another phone call at just after three. He answered on the third ring. "Is this Mr. Ray--uh. . ." The sound of shuffling papers. "Yes." The voice brightened perceptibly, strapped on a mask of friendliness. "My name is John Donovan. I'm an attorney representing the family of Donald Ackerman. I'm sorry to be calling so late." "It's not late for me." A laugh, intended to sound nervous or flustered. To Ray, it only sounded false. "That's right, of course. Only late for me. Do you mind if I tape record this conversation?" Smooth segue, meant to catch him off guard, startle him into acceptance. "Yes, I do mind. Can I help you?" You fucking bastard. John Donovan paused on his end of the line. Ray imagined him reaching for a legal pad upon which to take notes (just as he was supposed to imagine), though, of course, the tape recorder was still running. "Um, I was wondering if I could get some information?" "Sir, federal law prohibits me from acknowledging either to confirm or deny the presence of the individual of whom you have spoken or his participation in our program." Ray grinned. "Very well done," the lawyer said. "I guess that sets the parameters." "I guess it does." "Were you working two nights ago." "Sir, I am bound by Center policy and state law from discussing with you the work schedule of our employees at this facility unless you are an officer of the law or bearing a subpoena, in which case, I am only authorized to refer you to my supervisor." Ray grinned again. He was enjoying this. "What if I told you I have possession of a subpoena?" "Have you spoken to our attorney?" Ray countered. "In fact, son, yes I have. This afternoon." Ray grunted. Standard level of communication. "That's good, because I haven't. Which means, of course, that I'm not prepared to talk to you at all until advised on my statement by legal counsel." According to the above context, choose the correct option to answer the following question. Question: What did Ray do that showed he was enjoying the conversation? Options: A. He laughed. B. He answered all John Donovan's questions. C. not enough information D. He grinned.

SINGAPORE What now? That is the question from the White House in Washington to the Blue House in Seoul and perhaps also inside the Ryongsong Residence in Pyongyang. Following the historic handshake here between a U.S. president and a North Korean leader, who inked their names to a document with vague but compelling promises, the question emanating from Sentosa's Capella Hotel was what will actually change on the Korean peninsula? Moments after the summit between Donald Trump and North Korea's Kim Jong Un concluded, VOA contributor Greta Van Susteren and I spent a few minutes with the U.S. president and his secretary of state, at the Capella. Trump was elated and within the hour would make a surprising announcement suspending "provocative" joint U.S.-South Korean drills on the Korean peninsula. "We had a great chemistry," the president, speaking to Van Susteren, said of himself and Kim. "We will do business." Secretary of State Mike Pompeo told us, "it's a great day." The president has essentially handed off to Pompeo the hard work of turning a sparse declaration on denuclearization into something truly transformative. Many will question whether Pompeo, who a decade ago was running an oilfield equipment company, is truly the man for the task. In Pompeo's background, however, are indications of his capabilities: First in his class at the U.S. Military Academy, time served on the House of Representative's intelligence committee, a brief stint as director of the Central Intelligence Agency and two meetings with Kim in Pyongyang. Perhaps he is now as astute as any American official on piecing together the Pyongyang puzzle. This correspondent an observer of the Korean peninsula over five decades, resident in Seoul for several years and once given the opportunity to frankly converse for a week (in 2013) in the North with KPA officers has gleaned some insight into the world's most reclusive state. Rarely can any collection of a few hundred words adequately encapsulate the geo-political conundrum. It is... According to the above context, choose the correct option to answer the following question. Question: Where did Pompeo go to school? Options: A. not enough information B. Seoul C. Pyongyang D. The U.S. Military Acadamy
