Which of the following supports a pre-reading activity?

Pre-reading activities are strategies used before learners engage with a text. Their purpose is to activate prior knowledge, build motivation, and set a purpose for reading, for example by predicting content from titles, images, or headings, or by brainstorming related vocabulary.

Among the given options, using a prediction task fits this definition directly: learners anticipate what the text will be about using available cues before they start reading, which activates their prior knowledge and gives them a purpose for reading.

• Summarising requires learners to have already read and understood the text, so it is a post-reading, comprehension-checking activity rather than a pre-reading one.

• Paraphrasing likewise requires learners to have already read and understood the text, so it too is a post-reading, comprehension-checking activity rather than a pre-reading one.

• Teaching grammatical structures is a focus-on-form activity that can occur at any stage of a lesson; it does not activate prior knowledge about the text's content or set a purpose for reading.

Therefore, using a prediction task is the option that supports a pre-reading activity.
