Because the Quran is spoken in classical Arabic, many of the later converts to Islam (mostly non-Arabs) did not always understand the Quranic Arabic, they did not catch allusions that were clear to early Muslims fluent in Arabic and they were concerned with reconciling apparent conflict of themes in the Quran. Commentators erudite in Arabic explained the allusions, and perhaps most importantly, explained which Quranic verses had been revealed early in Muhammad's prophetic career, as being appropriate to the very earliest Muslim community, and which had been revealed later, canceling out or "abrogating" (nāsikh) the earlier text (mansūkh). Other scholars, however, maintain that no abrogation has taken place in the Quran. The Ahmadiyya Muslim Community has published a ten-volume Urdu commentary on the Quran, with the name Tafseer e Kabir.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the name of the Ahmadiyya Jewish Community's published Quran commentary?
Ah, so.. unanswerable

While all dogs are genetically very similar, natural selection and selective breeding have reinforced certain characteristics in certain populations of dogs, giving rise to dog types and dog breeds. Dog types are broad categories based on function, genetics, or characteristics. Dog breeds are groups of animals that possess a set of inherited characteristics that distinguishes them from other animals within the same species. Modern dog breeds are non-scientific classifications of dogs kept by modern kennel clubs.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who keeps classifications of different dog breeds?
Ah, so.. modern kennel clubs.

When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold). Xbox Live Free is included with all SKUs of the console. It allows users to create a user profile, join on message boards, and access Microsoft's Xbox Live Arcade and Marketplace and talk to other members. A Live Free account does not generally support multiplayer gaming; however, some games that have rather limited online functions already, (such as Viva Piñata) or games that feature their own subscription service (e.g. EA Sports games) can be played with a Free account. Xbox Live also supports voice the latter a feature possible with the Xbox Live Vision.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What key feature is not supported by the free version of Live?
Ah, so..
multiplayer gaming
