Question 47: Seeing adults – and children – who simply refuse to be unglued from their cellphones, no matter where they happen to be, is very common. Cellphone users often seem to forget that others share the same planet, and the talkers can be completely insensitive to those around them – to the noticeable annoyance of non-cellphone users. Cellphones have lives, increased business opportunities, and kept friendships going, but they have also been known to destroy the magic of the movies, make everyone at a restaurant turn around and stare, and bring many a meeting to an abrupt halt. People have even been known to carry their mobile phones to funerals! Your cellphone is undoubtedly very important to you because it keeps you in touch with the hundreds of urgent things you have to do every day. If you are a frequent cellphone user, you will insist that these gadgets are, after all, supposed to be anywhere – anywhere phones. Isn’t that why we call them mobile? It is true that cellphones would not be of much use if you could not use them anywhere and anytime. And that is exactly why most cellphones come with a host of features you can use to ensure that disturbance to others is kept to a minimum. Even the most basic cellphones have a range of ring settings, with some adequate soft-toned not to annoy those around you. Some phones vibrate or flash a light to alert you, and some let out quiet little beeps. The voice mail option allows you to switch off and still no miss any calls or messages at all. So enjoy the benefits that cellphones bring, and at the same time, show consideration for others. The author seems to think that taking cellphones to funeral ________.

Verse 48: Despite the fact that too much fat can be harmful, a moderate fat intake is actually essential to the maintenance of good health. Some of the symptoms of fat deficiency include flaking skin, emaciation, reduced functioning of the immune system, and fertility problems. Recent studies have linked fat-free diets to increased stress and aggression, and note that those who try to eliminate fat completely from their food intake may be at risk for developing eating disorders: a small amount of fat in a meal will produce a feeling of satiety which lasts much longer than the sensation of fullness produced by protein or carbohydrates. At least two teaspoons of fat per day is needed in order for the digestive system to absorb vitamins A, D, E and K, which are fat soluble. These vitamins are essential for healthy hair, skin, teeth, and eyes. Without the ability to absorb these vitamins, children run the risk of developmental and neurological disorders. Adults need these vitamins to produce fertility hormones. Some types of fat actually help to reduce harmful cholesterol levels. Polyunsaturated fats such as corn, soybean, and sesame oil, and monounsaturated fats like chicken fat and olive oil, seem to lower blood cholesterol, while saturated fats – those found in red meat, dairy products, and tropical oils – seem to raise the level of the kind of cholesterol that accumulates as plaques on arterial walls. Paying attention to the type of fat consumed is just as important as reducing total fat intake. The word “accumulates” in the passage is closest in meaning to_________.
