Concept:
- Three of the four options are Korean or general, and only one is the single most famous printed page in the chapter on print culture.
- Grouping the options by country of origin settles this question quickly.
Step 1: Group the options by origin.
Korean Jikji and Tripitaka Koreana are both Korean works. Chinese script is a writing system rather than a book. That leaves the Diamond Sutra as the only single Chinese printed book on the list.
Step 2: Match the grouping with the picture.
The page carries Chinese characters and is laid out as one printed sheet of a scroll. A Chinese printed book therefore fits, and the two Korean choices do not.
Step 3: Use the date clue from the chapter.
The Diamond Sutra of 868 CE is the earliest printed book with a date on it, and its page is the image used again and again to show how woodblock printing worked.
Step 4: Rule out the writing-system trap.
Option (D) is worded to tempt a student who sees Chinese characters and stops there. The question says identify the picture, which means name the work and not the script.
Final Answer: (B) Diamond Sutra
