Reаd the fоllоwing pаssаges and determine the authоr’s implied topic and main idea. Passage C The Aswan High Dam, built in Egypt with Russian support, was supposed to provide hydroelectric power and to increase Egypt’s food supply by controlling the unpredictable Nile River. The project meant that great art treasures were flooded as submerged land was drained for cultivation. However, only one-tenth of an acre of land was made available for each person added to Egypt’s population during the period of construction. One result of the dam was that the Nile no longer flooded the delta farmlands annually. These annual floods served to restore the farmland fertility with deposited silt. This no longer the case, the quality of the farmland decreased. The dam also cut off the nutrients that had been washed to the Mediterranean Sea as a result of the annual floodings. Because of this, or the change in the salinity of the sea that the dam produced, the sardine catch dropped from 18,000 tons per year to 500 tons per year. The stable lake created by the dam allowed aquatic snails to flourish. The snails serve as an intermediate host to a blood fluke that bores into humans causing the dreaded disease, schistosomiasis. The construction of that dam had important political implications at the time.

One of the challenges in reducing sugar for heart health is how hidden it is in everyday foods. Even items labeled “low-fat” often contain added sugars to make up for taste. Breakfast cereals, salad dressings, pasta sauces, and even some breads can be loaded with added sugars. The American Heart Association recommends that men consume no more than 36 grams (9 teaspoons) of added sugar per day while women should limit themselves to 25 grams (6 teaspoons) daily. Unfortunately, one can of soda alone can exceed these limits. Sugar may taste sweet, but its effects on the heart are anything but. While many people associate sugar with weight gain or cavities, few realize the serious toll it can take on cardiovascular health. Research over the past decade has made one thing clear: a high-sugar diet significantly increases the risk of heart disease—even in people who aren't overweight. When we consume excess sugar—especially from added sugars found in soda, desserts, and processed foods—our body undergoes several changes that can stress the cardiovascular system. One of the first effects is increased blood pressure. Sugar prompts the kidneys to retain sodium and water, which raises blood volume and strains the heart. In addition, sugar promotes chronic inflammation, a condition where the body's immune response remains constantly active. Over time, inflammation can damage arteries, making them more prone to plaque buildup and narrowing. This contributes to atherosclerosis, a major cause of heart attacks and strokes. Sugar also disrupts healthy cholesterol levels. It can lower HDL ("good") cholesterol and raise levels of LDL ("bad") cholesterol and triglycerides, fats in the blood that, when elevated, are strongly linked to heart disease. A large study published in JAMA Internal Medicine found that people who got 17%–21% of their daily calories from added sugar had a 38% higher risk of dying from heart disease compared to those who consumed less than 10%. This shows that sugar’s impact on the heart is dose-dependent and cumulative. Even if you don’t feel or look unhealthy, consuming too much sugar regularly can silently damage your heart over time. The connection between sugar and heart health is undeniable. From raising blood pressure and cholesterol to triggering inflammation, sugar can significantly increase your risk of heart disease. Reducing added sugar in your diet—even by a little—can protect your heart and improve your overall health. So the next time you reach for something sweet, think of your heart and choose wisely. 1.
