הכלללא קוראים את הקטע ואז את השאלות. קוראים את השאלות קודם, ואז קוראים את הקטע כשאתם כבר יודעים מה אתם מחפשים - זה ההבדל בין לסיים בזמן ללא לסיים.

2קראו את הקטע ברצף אחד. אל תעצרו על מילה לא מוכרת - ההקשר יסביר אותה, ואם לא, כנראה לא צריך אותה.
3סמנו בראש איפה כל פסקה נמצאת: על מה היא, ומה תפקידה בטיעון.

המלכודתאפשרות שנכונה בעולם אבל לא נאמרה בקטע. המבחן שואל מה כתוב, לא מה נכון - וידע כללי הוא מה שמפיל כאן, במיוחד כשהנושא מוכר לכם. אם אי אפשר להצביע על השורה, זו לא התשובה.

שאלה 1
Read the passage:
Anyone who spends a day at the seaside will notice that the water does not stay in one place. At some hours it covers most of the beach, and at others it pulls far back, leaving wet sand and rock pools. These regular changes are called tides, and most coasts have two high tides and two low tides a day.
Tides are caused mainly by the Moon. The Moon's gravity pulls on the Earth's oceans and creates two bulges of water, one on the side of the Earth facing the Moon and one on the opposite side. As the Earth turns, each coast passes through both bulges, so the sea rises and falls twice. The Sun also pulls on the oceans, but because it is so much farther away, its effect is less than half as strong.
When the Sun and the Moon are in line, at new moon and full moon, their pulls add together, and high tides are extra high. These are called spring tides, although they have nothing to do with the season. When the two pull at right angles, the difference between high and low water is smaller, and these are called neap tides. The shape of the coast matters too. In the Bay of Fundy in Canada, the water can rise and fall by more than fifteen metres.
Which of the following is the best title for the passage?
אThe Beaches of Canada
בHow the Sun Heats the Oceans
גWhy the Sea Comes and Goes
דWhy Spring Is the Season of High Water

שאלה 2
Read the passage:
Every photograph, song and message stored on a computer is, at the most basic level, a long series of zeros and ones. This system, known as binary, uses only two digits, unlike the familiar decimal system, which uses ten. Just as the decimal number 305 means three hundreds, no tens and five ones, each position in a binary number represents a power of two, so the binary number 101 means one four, no twos and one one: five.
The reason computers rely on binary lies in their hardware. A modern chip contains billions of tiny switches called transistors, each of which is either on or off. Distinguishing between two states is far more reliable than distinguishing between ten. A small change in voltage caused by heat or electrical noise is unlikely to turn an "on" into an "off", whereas it could easily turn a six into a seven if a single wire had to carry ten different levels. Consequently, engineers have found it simpler and cheaper to build machines that handle huge numbers of simple two-state signals.
Text is handled in exactly the same way. Under a widely used standard, the capital letter A is stored as the number 65, which the machine records as 1000001. A single binary digit is called a bit, and a group of eight bits is called a byte.
Which of the following is the most appropriate title for the passage?
אThe Long History of the Decimal System
בHow Transistors Are Manufactured
גWhy Computers Make So Many Errors
דThe Two-Digit Language of Machines

שאלה 3
Read the passage:
In April 1815, Mount Tambora in Indonesia produced the most powerful eruption in recorded history. The immediate devastation was local, but its most far-reaching consequences came the following year, thousands of kilometres away. In 1816, much of Europe and eastern North America endured a summer of frost, snow and incessant rain; harvests failed, food prices soared, and hunger and unrest followed. It came to be remembered as the Year Without a Summer.
The culprit was not the ash, most of which fell out of the atmosphere within weeks, but sulphur dioxide. Injected into the stratosphere, above the weather that would otherwise wash it out, the gas formed a fine haze of sulphate droplets that reflected part of the incoming sunlight back into space. Such a veil can persist for a year or more, lowering temperatures across the globe. The 1991 eruption of Mount Pinatubo in the Philippines, far smaller than Tambora, nonetheless cooled the planet measurably for about two years.
It might seem to follow that volcanoes offset global warming, but the comparison is misleading. Their cooling is transient, whereas carbon dioxide from human activity accumulates over centuries; human emissions now exceed those of all the world's volcanoes many times over. Some scientists have proposed imitating eruptions by deliberately releasing sulphate particles, yet the idea remains highly controversial, partly because it would mask warming rather than remove its cause.
Which of the following is the most suitable title for the passage?
אThe Hungry Year in Europe
בEruptions, Sunlight and a Colder World
גA Volcanic Cure for Modern Global Warming
דHow Volcanoes Are Formed

שאלה 4
Read the passage:
Visitors to medieval churches are sometimes told that the panes in the windows are thicker at the bottom because glass is really a very slow-moving liquid that has sagged under gravity over the centuries. The explanation is appealing, and it contains a grain of truth: glass is an amorphous solid, lacking the orderly crystalline structure of, say, ice or metal, and physicists still debate how best to classify it. As an account of the windows, however, it collapses under scrutiny.
The irregularities are far better explained by how the panes were made. Before modern techniques, window glass was often produced by spinning a blob of molten glass into a large disc, which inevitably varied in thickness, and glaziers generally, though not invariably, set the heavier edge at the bottom. Panes installed thick side up do exist, which is hard to reconcile with centuries of downward flow. Moreover, if glass flowed perceptibly at room temperature, ancient Roman glassware and centuries-old telescope lenses, whose precise shapes remain intact, would have deformed long ago.
Calculations based on the viscosity of glass settle the matter: at ordinary temperatures, noticeable flow in a window would take far longer than the age of the universe. The myth persists, perhaps, because it offers a vivid explanation for a real observation, which is more than can be said for the mundane truth.
Which of the following is the most suitable title for the passage?
אUneven Windows and a Persistent Myth
בHow Telescope Lenses Are Made
גThe Crystal Structure of Ice and Metal
