Read the last paragraph of the text again and choose the right answer to the question after it.

In summer I have to go by bicycle when there is a traffic jam. It takes about an hour and a half. It’s a bit long but much faster than walking. I have nothing to complain about, because the weather forecast is good for this week. And if there are a lot of traffic jams, I will get to the office and enjoy the nice weather.

The question is:

Why does the author go by bicycle in summer time?

because there is a traffic jam and it is much faster than walking
because it helps to keep fit
because it is an ecological way of travelling

задание 5
Read the whole text one more time and choose the right answer to the question after it.

This week there are more traffic jams than usual. Buses, taxis, everything is blocked. In such situations, I take the subway. I live 20 minutes from the metro station, but if I walk fast, it takes me about 12 minutes. But when I take the subway, I have to spend 30 minutes to go to the office. That is why I prefer to go by bus.

I have a direct way without changing the transport. If it rains, I also take the bus. After that if I take the subway, my office is one hour from home. And it is about 40 minutes if I take the bus. I can also go by tram; it is cheaper a bit but it is much longer. I have to go with a lot of stops.
