Question

The image shows the taxonomic hierarchy. Which level contains organisms most similar to each other?
<!-- AI image prompt | slot:taxonomic_hierarchy_v3 | paste into Gemini/DALL-E/Midjourney: STRICT RULES — OBEY EVERY ONE OR THE IMAGE IS UNUSABLE:
(1) The image contains EXACTLY 16 text labels and nothing else: 8 hierarchy-level names + 8 example values. Listed top-to-bottom: "Domain" + "Eukarya"; "Kingdom" + "Animalia"; "Phylum" + "Chordata"; "Class" + "Mammalia"; "Order" + "Primates"; "Family" + "Hominidae"; "Genus" + "Homo"; "Species" + "Homo sapiens". (2) ZERO silhouettes, ZERO illustrations, ZERO icons, ZERO drawings of organisms anywhere on the image. NO Earth icon, NO animal silhouettes, NO human figure, NO plant drawings. The image is text-only with colored bars. (3) ZERO descriptive text beyond the 16 listed labels. NO words like "specific", "general", "narrow", "broad", "similar", "different", "shared", "unique". (4) ZERO arrows, ZERO numbering (no 1/2/3...), ZERO size emphasis (every row is the same height). (5) Background: pure flat white (#FFFFFF).

SUBJECT: One scientific textbook taxonomic-hierarchy chart. Canvas 1300x900, pure white background. Eight equal-height horizontal bars stacked top to bottom, no gaps between bars.

BARS — equal height (~95 px each), full canvas width except for ~50 px margin left and right. Each bar a different soft pastel color: row 1 = light violet (#d6c2e8); row 2 = light blue-violet (#c5cae8); row 3 = light blue (#b5d8eb); row 4 = light teal (#bdebda); row 5 = light green (#d4ebbd); row 6 = light yellow (#ebe5bd); row 7 = light orange (#ebd1bd); row 8 = light pink (#ebc2c8).

TYPOGRAPHY (each bar): On the left half of the bar, write the level name in bold black sans-serif ~36pt: "Domain", "Kingdom", "Phylum", "Class", "Order", "Family", "Genus", "Species". On the right half (~40%% of bar width from the left edge), write the example value in regular weight black sans-serif ~30pt: "Eukarya", "Animalia", "Chordata", "Mammalia", "Primates", "Hominidae", "Homo", "Homo sapiens" (italicize the last two as scientific names — "Homo" and "Homo sapiens").

FINAL REMINDER: The image is purely text-on-color-bars. NO organism silhouettes, NO Earth icon, NO any drawings. The student must KNOW that Species is the most specific level (= organisms most similar). Adding silhouettes whose count decreases bottom-down breaks the question by visually answering it. -->
