How does the writer present change in lines 49 to 66?

This question tests the writer's methods and their effect (R3 and R4) across an eighteen-line stretch. Ten marks means the examiner expects a shaped argument, not a list, and the mark scheme's top band asks specifically for a sustained interpretation.

1 to 3 marks: isolated detail or simple comment

Noting that a new hide has been built, or that avocets are back, and calling it 'a change'. Accurate, but the question already told you the topic is change.

4 to 7 marks: explanation

1. Change is presented as gain, not only as loss. Avocets, 'once vanished from this coast altogether, were breeding again on the scrapes behind the old sea defences' (lines 53 to 54). The word 'altogether' makes the earlier absence total, so the return is a genuine reversal rather than a slight improvement. [1]
2. Human change is treated the same way. A new hide stands 'where once there had only been a gap in the hawthorn hedge' (lines 49 to 50), and inside it a laminated chart records the birds now present. The reserve has acquired an institution and a record, which is why the writer can learn about the avocets at all. [1]
3. The vocabulary of the passage stops being nostalgic here. 'Recorded', 'listed', 'breeding' are administrative and biological rather than elegiac, and the shift in register signals that the writer is now reading the marsh rather than mourning it. [1]

8 to 10 marks: sustained interpretation

The top band belongs to candidates who notice that the passage moves from cataloguing change to accepting a principle. The turn is at lines 55 to 57: the marsh 'had not simply survived the years between my visits, it had rearranged itself entirely, gaining species even as it lost the shape I remembered'. 'Rearranged' is the key choice. It denies both decline and preservation and substitutes a third idea, redistribution, in which the total is not the point.

Then the writer supplies the authority for that idea by returning to his grandfather, who 'had taught me that a saltmarsh was never finished, that it was always being built and unbuilt by the same patient sea, and that a person returning to it should expect to find a stranger's shore' (lines 64 to 66). This is why the section is structured as it is. The lesson was given before the changes happened, so the writer is not inventing consolation on the spot; he is applying an inherited frame that lets him call the shore strange without calling it ruined. An answer that explains this sequence, inheritance first and observation second, has interpreted the passage rather than summarised it.

Where marks are lost

Working line by line from 49 to 66 almost guarantees a mark in the middle band, because chronology is not an argument. Decide your claim about how change is presented, then order your evidence to serve it.
