Reading Questions: Labelling a diagram

 The diagram is usually related to one part of the text. The first things you need to do is find the right section.

Usually, there are technical terms on the diagram and the same words will be in the text.

Therefore, you need to find these technical words and you will have the right section.

Read the sentences around the technical words to find the missing information.

Another possibility is that you need to fill in parts of a machine, for example, so the answers will be the technical words.

In this case, you need to read the descriptions in the text (shape, position) and match those descriptions to the right part of the picture.
