Solution

In the end, each of them have 18 picture cards:

54 : 3 = 18 (picture cards)

At first, Billy has 21 picture cards:

18 + 3 = 21 (picture cards)

At first, Paul has 13 picture cards:

18 - 5 = 13 (picture cards)

At first, Leon has 20 picture cards:

54 - (21 + 13) = 20 (picture cards)

Answer: Billy: 21 picture cards

              Paul: 13 picture cards

              Leon: 20 picture cards.

Read the passage carefully, the state whether the statements are True or False.

American students take part in different activities at recess. The energetic students often play basketball, but they never have time to play a whole game. They just practice scoring goals. This is called “shooting some hoop”. Many of the students listen to music. Sometimes they read or study at the same time. Some of the children, mainly boys, swap baseball cards. These pictures of baseball players come in packages of candy. They swap cards with their friends, so they get the ones they want. Eating and talking with friends are the most common ways of relaxing at recess. These activities are the same all over the world.

___ Baseball cards are very popular with boys as well as girls.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.

In Britain, greetings cards are sold in chain stores and supermarkets, in newsagents’ shops, corner shops and, increasingly, in shops that specialize in the sale of cards and paper for wrapping presents in.

The most common cards are birthday and Christmas cards. Many Christmas cards are sold in aid of charity and special „charity card shops’ are often set up in temporary premises in the weeks before Christmas. A wide variety of birthday cards is available to cater for different ages and tastes. Some, especially ones for young children or for people celebrating a particular birthday, have the person’s age on the front. Many have comic, often risqué, messages printed on them, and cartoon–style illustrations. Others are more sober, with reproductions of famous paintings or attractive original designs. The usual greeting on a birthday card is ‘Happy Birthday’, ‘Many Happy Returns’ or ‘Best Wishes for a Happy Birthday’.

Some people also send special cards for Easter and New Year. Easter cards either portray images of spring, such as chicks, eggs, lambs, spring flowers, etc, or have a religious theme.

Cards are produced for every ‘milestone’ in a person’s life. There are special cards for an engagement, a marriage, a new home, a birth, success in an examination, retirement, a death in the family, etc. Some are ‘good luck’ or congratulations’ cards. Others, for example ‘get well’ cards for people who are ill, express sympathy.

Which of the following is NOT the usual greeting on a birthday card?

A. Best Wishes for a Happy Birthday

B. Happy Birthday

C. Good luck

D. Many Happy Returns
