This is Set 2 of this part of the Cambridge English First Examination about a person who has invented a cardboard bike. The emphasis is on grammar and vocabulary.
Part 2 consists of a text in which there are 8 gaps. You are required to draw on their knowledge of the structure of the language and understanding of the text in order to fill the gaps.
In this part, as there are no sets of words from which to choose the answers; you have to think of a word which will fill the gap correctly.
