Read the passage:
Do Old Windows Flow?
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 NOT mentioned as evidence against the flowing-glass explanation?
אtemperature readings taken in medieval churches
בpanes that were installed with the thick side up
גthe intact shapes of ancient glassware
דcalculations based on the viscosity of glass

Read the passage:
Why Your Recorded Voice Sounds Strange
Many people are surprised, and even a little upset, when they hear a recording of their own voice for the first time. It often sounds higher and thinner than they expected, and some refuse to believe that it is really them. Yet their friends and family will say that the recording sounds exactly like the person they know.
The reason is that we hear our own voice in two different ways. When we speak, sound travels through the air to our ears, just as it does when we listen to other people. At the same time, the vibrations of our voice also travel through the bones of our head directly to the inner ear. These vibrations make the lower sounds seem stronger, so our voice sounds deeper and fuller to us than it really is.
You can test this with a simple experiment. Put your fingers in your ears and hum. The sound seems louder, because now you are hearing it mostly through your bones. A microphone, however, picks up only the sound that travels through the air. This means that the voice on the recording is the one that everyone else hears, while the voice in our head is heard by nobody but ourselves.
Which of the following is NOT mentioned in the passage?
אhow sound reaches our ears through the air
בwhy some voices are naturally deeper than others
גwhat happens when we hum with our fingers in both our ears
דhow friends react to a person's recorded voice

Read the passage:
Why Computers Count in Twos
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 NOT mentioned in the passage?
אthe name given to a single binary digit
בthe number of bits in a byte
גthe decimal value of the binary number 101
דwho invented the binary system

שאלה 4
Read the passage:
Reading a Rainbow
A rainbow can appear only when two conditions are met: the sun must be shining, and there must be raindrops in the air in front of the observer. An observer looking at a rainbow always has the sun behind them. For this reason, rainbows are most often seen in the early morning or late afternoon, when the sun is low and a shower is passing on the opposite side of the sky.
The colours are produced inside each raindrop. When sunlight enters a drop, it bends, or refracts, and because each colour bends by a slightly different amount, white light is separated into its components. The light then reflects off the back of the drop and bends again as it leaves. Red light emerges at an angle of about 42 degrees from the point directly opposite the sun, and violet at a slightly smaller angle, so the bow always has red on the outside and violet on the inside.
Sometimes a fainter second bow appears outside the first. It is produced by light that reflects twice inside the drops, and its colours are reversed, with red on the inside. The sky between the two bows looks noticeably darker. Since the angles depend on the position of the observer's eyes, no two people ever see exactly the same rainbow; each sees light from a different set of drops.
Which of the following is NOT mentioned in the passage?
אthe colour on the outside of the main bow
בwhere the sun must be when a rainbow is seen
גhow long a rainbow usually lasts
דthe order of the colours in the second bow
