Text structure and rhetorical purpose

Explain what a passage or sentence does within the writer's larger argument or narrative.

What you will tackle

  • Identify overall organisation and main rhetorical purpose
  • Explain the function of a sentence or detail
  • Distinguish speaker, narrator, character and author perspective

Function differs from subject matter

A sentence about a failed experiment might introduce a problem, qualify an earlier claim or supply a counterexample. Name the rhetorical move and explain its connection to surrounding sentences. An overall purpose should account for the passage's sequence, not just one detail.

Track whose perspective is represented

A character's claim is not necessarily the narrator's judgement or the author's opinion. A narrative may reveal a discrepancy between what a character believes and what the reader can infer. In an argument, distinguish a position being reported from the position being defended.

Build your notes, then practise

Work on paper before opening an explanation. Guided tasks provide a starting point; independent tasks remove the scaffolding; application tasks ask you to justify a method or interpretation in context.

Guided practice

Guided 1

Original passage: ‘The old explanation attributes the decline to weather. Yet records from sheltered sites show a similar fall. The new study therefore tests whether a shared change in food supply offers a better account.’ What does the second sentence do, and what is the overall purpose?

Show a starting hint

Label the move each sentence makes.

Compare with the explained answer
  1. The first sentence states an existing explanation.
  2. The sheltered-site evidence challenges its sufficiency.
  3. The last sentence introduces a competing explanation to investigate.

Answer / response criteria: The second sentence supplies a counterexample; the passage motivates testing an alternative explanation.

Independent practice

Independent 1

Original prose: ‘“No one has noticed,” Tomas thought, hiding the broken handle. Across the room, his sister set a tube of glue beside his cup and said nothing.’ Distinguish Tomas's belief from the evidence available to the reader.

Compare with the explained answer
  1. Tomas believes the damage has gone unnoticed.
  2. The sister's action implies awareness without stating her full motive.
  3. The narrative creates a discrepancy between his confidence and the reader's evidence.

Answer / response criteria: Tomas believes no one knows, while the glue suggests his sister may have noticed; the narrator does not directly confirm her motive.

Application practice

Application 1

Plan the structure of a short explanation that first introduces a common belief, then presents a counterexample and finally qualifies the belief. Write one sentence for each function on the topic ‘larger samples always remove bias’.

Compare with the explained answer
  1. State the belief clearly.
  2. Give a large but self-selected survey as a counterexample.
  3. Conclude that size reduces sampling variability under suitable designs but does not automatically remove selection bias.

Answer / response criteria: One valid sequence: ‘Large samples are often assumed to remove bias. A million volunteers from one interest group can still misrepresent a city. Sample design matters alongside size.’
