The wheel is perhaps the greatest invention in history. After its invention, travelling became faster and more comfortable. A few thousand years ago, people started to use wheels on carriages. In the early 19th century, the first trains began to carry passengers. At the start of 20th century, cars became popular. Without the wheel, we would not have these inventions.

A. Would you prefer to travel alone or travel in a group?
B. Travelling in a group is superior over travelling alone in all aspects.
B In any travel there might be risks, such as unexpected hurt by wild animals, rocks and floods, or there might be other emergencies such as diseases or accidents. In such occasions friends may give immediate help. However, if you are travelling alone, such immediate help would be impossible. In addition, being with friends may add extra pleasure to the travel. They can share your loneliness, talking with you about the sights whereas you may feel lonely and bored when travelling alone.
