Passage 2 Questions 1to 5 are based on the following passage:
Sometimes a book can help change history. One book that certainly did was Uncle Tom’s Cabin, Written by Harriet Beecher Stowe. It was a book that spoke out against slavery.
As Harriet Beecher Stowe wrote her book, there were over3.5 million slaves in the United States. Slaves were usually in the cotton-growing states of the South. The Northern States has ended slavery.

In the South, many people were very angry at the people in the North. By 1861 the two parts of the country were at war. The Civil War, which lasted until of cease, was made to happen by many things.

Did you know that London is one of the most multicultural cities in the world？ Here, there are about 300 different cultures living side by side. Forget tea and sandwiches, now it is more common for a Londoner to drink cappuccino for breakfast, and eat Thai food for lunch in the local pub. Let’s see how life has changed in Britain’s capital.
A India
Most people from India arrived in London in the 1950s and 60s. Now there is a strong Asian presence here – in the shops, markets and, of course, the restaurants.

Southall, in the far west of the city, is one of many places well known for its Indian culture.
B Poland
This community represents more than 1% of the UK’s total population and is growing rapidly. In London, many Polish people live in the Hammersmith area, in the west of the city. Here, there are several Catholic churches, and delicatessens which sell the country’s specialities such as beetroot soup (barszcz) or Polish cakes and snacks. Were they right to come？ Young Poles say they can easily earn three times as much money here as at home, where unemployment remains high.
C West Africa
