Question

A long-running online television episode guide provides a "New Episodes Today" feature that organizes daily listings by country using two-letter abbreviations. Identify all the countries included in that daily listing feature and, for each one, provide (1) its full country name and (2) its corresponding ISO 3166-1 alpha-2 country code. Ensure your answer covers every country represented in the feature.

Answer length: 200-300 words.

Depth checklist

United States, United Kingdom, Canada, Australia, New Zealand, Japan, and South Korea – identified as the complete set of countries listed under the daily 'New Episodes Today' feature, represented by the abbreviations US, UK, CA, AU, NZ, JP, and KR
Logic proof: The entities are derived specifically from the grouped country abbreviations presented together under a single daily new-episode listing category, requiring enumeration of the full set rather than a partial selection

Width checklist

United States – ISO code US
United Kingdom – ISO code GB (noting that UK is commonly used but GB is the official ISO 3166-1 alpha-2 code)
Canada – ISO code CA
Australia – ISO code AU
New Zealand – ISO code NZ
Japan – ISO code JP
South Korea – ISO code KR

Examiner rationale

The question uses deep logic by requiring the solver to identify a specific grouped feature (a daily new-episode listing organized by country abbreviations) and infer the full set of countries from that structure. It uses wide aggregation by requiring complete coverage of all listed countries and additional structured details (full country names and ISO alpha-2 codes) for each, ensuring multi-entity retrieval and verification.

Judgment

Tie

BOTH

Score 0 - 0

First, Deep Logic: Both agents fail to identify the correct complete set of countries (United States, United Kingdom, Canada, Australia, New Zealand, Japan, and South Korea). Agent A incorrectly includes Ireland and omits Japan and South Korea. Agent B incorrectly includes the Netherlands and also omits Japan and South Korea. Therefore, both fail the core entity requirement. Second, Width/Completeness: Both miss two required countries (JP and KR) and introduce one incorrect country each, so both fail the checklist aggregation requirement. Finally, Presentation & UX: Agent B has slightly better formatting and clearer structure, but accuracy is foundational. Since both responses contain significant factual errors and fail the main entity identification, this qualifies as a LOW-quality tie under the rubric.

Each tag already matches its official ISO 3166-1 alpha-2 country code, with the sole nuance that the site displays “UK” while the ISO code for the United Kingdom is “GB”; otherwise the abbreviations correspond exactly.

The “New Episodes Today” country list on the TV episode guide uses these two-letter abbreviations, each matching the ISO 3166-1 alpha-2 code for that country: AU — Australia; CA — Canada; NL — Netherlands; NZ — New Zealand; UK — United Kingdom; US — United States.[1][2] This appears to be the complete set of countries represented in that daily listing feature. On the site’s “New Episodes Today” page, the daily schedule is grouped under those six abbreviated headings, indicating the territories for which the guide tracks first-run or newly aired episodes on that date.[1] Cross-checking each abbreviation against the ISO 3166-1 alpha-2 standard confirms that all six are valid ISO country codes with the corresponding full country names listed above.[2] For clarity, the full mapping is: - AU = Australia [2] - CA = Canada [2] - NL = Netherlands [2] - NZ = New Zealand [2] - UK = United Kingdom [1][2] - US = United States [2] A small note: although “UK” is widely used and is the label shown in the feature, the formal ISO 3166-1 alpha-2 code for the United Kingdom is also “GB” in the standard’s core assignment, while “UK” is exceptionally reserved and commonly used in practice.[2] Since the question asks for the codes represented in the feature, “UK” should be reported exactly as used there.[1] ## References [1] EpGuides, “New Episodes Today” page, showing country tabs/listings by abbreviation. https://www.epguides.com/new/ [2] ISO 3166 country code reference, including AU, CA, NL, NZ, GB/UK, and US. https://www.iso.org/obp/ui/#search/code/
