(Questions 25-30) Read the following passage and answer the questions that follow:
David
I spent some time gazing at ‘David’ inside the Galleria dell’Accademia.

(Questions 53-56) Read the following passage and answer the questions as follow:
In a Spin
You have only to watch the daily movement of the sun and the nightly turn of the stars across our sky to realise that the Earth is turning. While you may be standing completely still on the surface of the Earth, that surface is itself turning at a rate of about 1700 km/h. At this rate, our planet takes 23 hours and 56 minutes to make one full rotation on its axis relative to any distant fixed star – a period of time that astronomers call a sidereal day. This is a tiny bit shorter than our ordinary solar day which is 24 hours long – the time between high noon on two consecutive days. The sidereal and solar days are different lengths because by the time the Earth has made one full rotation on its axis and the distant star is directly overhead again, the Earth has also moved 0.986 degrees further around its nearly
18
circular orbit around the sun. As a result, at the end of a sidereal day, the Earth must continue to rotate that extra 0.986 degrees until the sun is overhead to complete a solar day. This extra rotation takes 4 minutes.
There are a number of factors that affect the rate at which a planet turns on its axis. Mercury, the closest planet to the sun, rotates much more slowly than Earth because of the dragging effect of the sun’s enormous gravity. A solar day on Mercury is the same length as 58 Earth days! Our own Earth’s spin is being slowed down by the tidal effect of the Moon and scientists have found that the Earth solar day is getting longer at a rate of 1 second every thousand years.
Q.53 Which of the following statements is true?
1) The sun is speeding up the Earth’s rate of spin.
2) Our clocks use the solar day as it is more convenient.
3) The sidereal day is longer than the solar day on Earth.
4) All planets in our solar system have the same length of sidereal day.
Q.54 What would happen if the Earth’s spin were to slow down?
1) Night-time would be longer than daytime.
2) The solar day would be shorter than the sidereal day.
3) The sidereal day and solar day would both be longer.
4) There would be more hours of daylight than hours of darkness.
Q.55 Venus spins in the opposite direction to that in which it orbits the sun, therefore
1) its sidereal day is longer than its solar day.
2) its solar day is longer than its sidereal day.
3) the length of its sidereal day is constantly changing.
4) the length of its sidereal day and its solar day are the same.
Q.56 Mercury rotates at a speed of 11 km/h. Therefore the circumference of Mercury is approximately
1) 1 550 km.
2) 9 200 km.
3) 12 100 km.
4) 15 600 km.
(Questions 57 to 60) Read the following passage and answer the questions that follow:
Bits and Bytes
While human communication is made up of letters and numbers, the processors within computers and other digital appliances communicate using a system called binary. The bi in binary means “two”. So the system is based on only using two options: either 0 or 1.
The binary system uses bits and bytes. Each bit can only have one of two values – either 0 or 1. A byte is a sequence of 8 bits. An average text file is made up of about 100 kilobytes (which is 100 000 bytes or 800 000 bits) while a TV show downloaded from the internet may be many gigabytes (1 000 000 000 bytes) in size!
19
Computer processors run billions of calculations every second. Each calculation involves converting our normal base 10 numbers which are in combinations of 10 digits, (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) into a binary code, using base 2 numbers, or powers of 2. This results in a sequence of only 0s and 1s as you can see from the table below. This table shows how base 10 numbers are coded into 4 bits. More bits would be needed for bigger numbers.

Binary can also be used to encode images for transmission over networks. The simplest versions work by breaking up an image into a series of squares. Squares that are dark are given the value 0 while those that are light are given the value 1. Each row of squares can then be represented by a sequence of bits as shown:
Squares turned into bits Rows of bits turned into a
sequence with spaces separating each row’s values
Image broken into squares

Q. 57 What binary sequence would be formed from the image below?
1) 110 110 101
2) 000 001 110
3) 001 001 010
4) 111 110 001
Q.58 Using the pattern indicated in the table, what would be the binary
code for the integer 13?
1) 1101
2) 1110
3) 1111
4) 10001
Q 59. Which of these numbers would be written as 10000 in binary code?
1) 14

During their last year at school, a teacher gave his students a questionnaire about Life Skills. One conscientious student had breezed through the questions until he read the last one: “What is the first name of the woman who cleans at your floor in the school?” Surely this was some kind of joke. He had seen the cleaner several times. She was tall, dark-haired and in her 50s, but how would he know her name? He handed in his paper, leaving the last question blank.
Just before class ended, the student asked if the last question was important. “Absolutely”, said the teacher. “In your career, you will meet many people. All are significant. They deserve your attention and care, even if all you do is learn their name, smile and say “hello.”

(Questions 53 to 56) Read the following passage and answer the questions that follow:
The Pendulum Swing
A child moving backwards and forwards on a swing, the timing mechanism of a Grandfather clock and a weight swung to and fro on the end of a string are all examples of pendulums – devices first studied by the scientist Galileo Galilei in 1581. He noticed that, although all of the lanterns suspended from long chains in a cathedral swung backwards and forwards, they did so at different rates. He started to wonder what had the biggest effect on the period (the time taken for a lantern to make one complete swing forward and backward) – the length of the chain, the mass of the lantern or how far back the lantern was first moved before it started to swing (called its amplitude). As a scientist, he performed hundreds of experiments until he found out that all swinging objects or pendulums followed the same rules: firstly, pendulums that had the same length had the same period regardless of amplitude or the size of the mass at their end and, secondly, that the square of the period in seconds was proportional to the length of the pendulum.
Q.53 In Galileo’s experiments to determine how the length of the pendulum affects its period, the independent variable would have been the pendulum’s
1) time.
2) mass.
3) length.
4) amplitude.
Q.54 While investigating the effect of a pendulum’s mass on its period, the pendulum string breaks when you are only half way through collecting your 50 pieces of data. Which course of action is the most likely to produce unreliable results?
1) Knotting the string back together and continuing to collect data.
2) Using only the data that you collected before the string broke.
3) Starting the experiment over again with a new pendulum string.
4) Starting the experiment again using the shortened pendulum string.
Q.55 Pendulum A swings twice during the time that pendulum B swings once. What is the relationship between their lengths?
1) Pendulum A is twice as long as pendulum B.
2) Pendulum B is twice as long as pendulum A.
3) Pendulum A is four times longer than pendulum B.
4) Pendulum B is four times longer than pendulum A.
Q.56 Two pendulums, of different lengths are pulled back and released at the same time. If one has a period of 2 seconds and the other 3 seconds, how many times in a minute will both pendulums be back at their respective release points at the same time?
19
1) 10
2) 12

4) 40
(Questions 57-60) Use the following information and answer the questions that follow:
Using levers
The lever is a simple machine that allows an effort force to lift a load by means of a fulcrum or turning point. A seesaw in a playground is an example of a lever, with the riders at either end taking turns to be the load or to apply the effort force. If the riders have the similar weights, the seesaw works well.
If the difference between the weights of the riders is very large, however, the seesaw can only work properly if the larger person slides closer to the fulcrum. In general, the seesaw functions at its best when the product of the weight and the distance from the fulcrum equals the same value for each rider. This is shown in the diagrams below.
40 kg
1.5 m
0.75 m
80 kg
40 kg
40 kg
1.5 m
1.5 m

This same lever principle also allows us to lift very heavy loads with little effort provided that the lever we use is long enough and the fulcrum is placed close to the load.
Q.57 When using a screwdriver to open the lid of a can of paint, a lever action is used.
In this situation, the fulcrum of the lever is the
1) lid of the paint can.
2) rim of the paint can.
3) tip of the screwdriver.
4) the handle of the screwdriver.
Q.58 A 60 kg woman wants to ride on a playground seesaw with her 20 kg child. Which combination of the positions shown in the table below would provide the most balanced ride?

Q.59 A farmer uses a 2 m long lever to lift large rocks from the ground of his field. He places a fulcrum 20 cm from the rock end of the lever and then stands on the other end, levering out the rock.
If the farmer weighs 100 kg, what is the heaviest mass of rock that he can lift using this method?
1) 200 kg
2) 900 kg
3) 1800 kg
4) 2000 kg
Q.60 Here are two other examples of levers:
Which of the following statements is true?
1) Not all levers have a fulcrum.
2) The effort force is usually smaller than the load.
3) The fulcrum must be between the load and the effort force.
4) The effort force and the load need to be the same distance from the fulcrum.
