Text Extract (Paragraph D):
"For more than a century, the IPK had been treated as the perfect standard. However, when the IPK was compared with its official copies in 2007, a disturbing fact emerged. The IPK was found to be 50 micrograms lighter than the average of the copies. No one knows why. It could be due to surface contamination, loss of gas from the alloy, or a mysterious quantum effect."

Answers:
1. TRUE Explanation: Paragraph A states: "For the first time in human history, being overweight has become a bigger global health crisis than hunger." Since hunger is synonymous with malnutrition, the statement is true. A Weighty Issue Ielts Reading Answers
2. FALSE Explanation: Paragraph A states that every region is seeing an increase in obesity rates, "The only region that has successfully bucked this trend is Sub-Saharan Africa." To "buck the trend" means to go against it (in this case, not seeing an increase), but the statement says there has been a decrease, which is not claimed in the text. The text implies rates are not increasing, or malnutrition is the primary issue, but elsewhere implies the trend is rising globally. Wait, looking closer at Paragraph A: "every region... is seeing an increase... The only region that has successfully bucked this trend is Sub-Saharan Africa." Correction: If they "bucked the trend" of increasing rates, their rates did not increase. The statement says there was a decrease. The text does not say they decreased, only that they did not follow the rising trend (or that malnutrition is still the main issue). Therefore, we cannot say it is TRUE. Re-evaluation: Actually, usually "bucking the trend" of rising obesity implies rates are stable or low. The statement claims a decrease. Since the text doesn't explicitly say numbers went down, just that they didn't follow the rise, this is a tricky one. However, usually, in IELTS, if the text says "X is the only place not seeing an increase," and the question says "X saw a decrease," it is often FALSE (because "not increasing" includes staying the same) or NOT GIVEN. Let's look at the standard answer key for this specific text (which is adapted from a real report summary): The text says every region is seeing an increase. Sub-Saharan Africa bucked this trend. Trend = Increase. Bucked the trend = Did not increase. Statement = Decrease. Did not increase $\neq$ Decrease (It could be stable). Therefore, the statement contradicts the implication of "increase" or provides specific info not found. Self-Correction based on typical IELTS logic: If the text says "Obesity is rising everywhere," and then "Sub-Saharan Africa bucked the trend," it means it is not rising there. The statement says it decreased. Since "not rising" does not mean "decreasing," the information is not confirmed. However, usually, for a generic TRUE/FALSE, if the text says "Obesity is a bigger crisis than hunger globally," that is true. Let's stick to the clearest answers. Actually, let's adjust the answer key to be safe: Answer: NOT GIVEN. (The text says they "bucked the trend" of increase, meaning they did not go up. It does not confirm if they went down).
3. FALSE Explanation: Paragraph B states: "high blood pressure remains the top risk factor... the rise in body mass index (BMI) is now a close second." The statement claims high blood pressure is the second highest. It is actually the first.
4. FALSE Explanation: Paragraph C quotes Professor Lopez saying: "individual willpower is no longer enough." This contradicts the statement that he believes it is sufficient.
5. NOT GIVEN Explanation: Paragraph E discusses the future: "the economic burden of obesity will surpass that of smoking... within the next two decades." It compares the future burden. It does not explicitly state the current cost comparison, though it implies obesity is rising. Since specific current figures are not compared, it is Not Given.

7. regulating / regulate Explanation: Paragraph C says: "Lopez suggests that governments must intervene to regulate the food industry..." (Note: The summary sentence structure "begin ______" requires a gerund (-ing) or a noun. "Regulating" fits best. If the question was "must ______," then "regulate" would be the answer. Let's check the grammar: "begin regulating"). Correction: The text says "intervene to regulate". The summary says "begin ______". "Begin to regulate" or "begin regulating". Let's assume the word count allows. Let's use regulating.
