  "note": "A 2006-curriculum chemistry NOC'd in February 2018, whose eight chapters are the same eight titles in the same order as Sindh's, with the convergence running down to matching section headings. Structurally it is the clearest example of the narrow-and-thick design: about thirty pages per unit across eight units, against Punjab's roughly thirteen pages across thirteen chapters. Its religious content is historical rather than scriptural, a section on the Muslim period from 600 to 1600 AD describing it as the era of the alchemists, which is why A1 sits at 2 with no scripture anywhere. Its most cited feature is a gender one and it is unflattering: this book contains the corpus's only named woman scientist, and only as the answer to a naming puzzle about why curium's symbol is Cm rather than C, Cu or Cr. Marie Curie never appears as a scientist who did something, which is why the A7 of 5 stands despite the mention. The book also has zero climate-change content.",
