Read the passage below, and then answer the question that follows.

Gideon turned the page of the herbarium, his fingers lingering on the dry, brittle frond of a *Polystichum munitum*. The specimen was dated August 14, 1912—a summer of relentless heat and dust that had choked the valley. It was on that very afternoon, under the shadow of the dying sycamore, that his father had first spoken of selling the timber rights. Gideon could still hear the dry scrape of the pen as the contract was signed, a sound that now seemed to echo in the rustle of the parchment beneath his hands. Suddenly, a sharp knock at the study door shattered the memory. His sister entered, her face pale, holding the morning post. She did not speak, but the black border on the envelope she held told him everything. Before he could reach for it, his mind retreated once more to the image of the sycamore falling, the long, groaning sigh of the wood as it split, a sound he had spent fourteen years trying to forget. He looked down at the fern; the green had long faded to a dull, metallic grey, yet it remained intact, preserved in its arrest of time, while the family estate lay in ruins around him.

In the passage, the disruption of chronological order when Gideon’s mind retreats to the falling sycamore primarily serves to do which of the following?
