V.Read the passage carefully, and then answer the question below.

In the 1970s, skateboarding suddenly became very popular. At first, skateboarders moved slowly on flat,smooth areas. Then they began to ride quickly. This is called ‘freestyle’ skateboarding. Soon they were skateboarding skillfully up ramps and doing tricks in the air. This is called ‘ramp’ skateboarding. Then they started skateboarding and doing tricks on the street. This was ‘street-style’ skateboarding – a combination of freestyle and ramp. For this, the skateboarders needed protective clothing such as knee and elbow pads and helmets. This allowed them to skateboard safely.

Today skateboarding is still a very popular sport, and there are lots of competitions.
