(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.

I don’t intend to wait for that, but, like the people in fairy tales, travel away into the world and seek my fortune. I know I can find it.”

(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
