The 168-page extraction could not be theme-graded at all — the chapter marker returns nine scattered hits that resolve into no structure — so it is excluded from every cross-board comparison. Its A1 of 1 and A7 of 5 are placeholders scored by analogy with the board's other science volumes. Treat both as not established.",
