Question: At over 5 million, Puerto Ricans are easily the 2nd largest Hispanic group. Of all major Hispanic groups, Puerto Ricans are the least likely to be proficient in Spanish, but millions of Puerto Rican Americans living in the U.S. mainland nonetheless are fluent in Spanish. Puerto Ricans are natural-born U.S. citizens, and many Puerto Ricans have migrated to New York City, Orlando, Philadelphia, and other areas of the Eastern United States, increasing the Spanish-speaking populations and in some areas being the majority of the Hispanophone population, especially in Central Florida. In Hawaii, where Puerto Rican farm laborers and Mexican ranchers have settled since the late 19th century, 7.0 per cent of the islands' people are either Hispanic or Hispanophone or both.
Is there an answer to this question: Which group is least likely to be proficient in English?

Answer: unanswerable


Question: In 1965, Pope Paul VI decreed in his motu proprio Ad Purpuratorum Patrum that patriarchs of the Eastern Catholic Churches who were named cardinals (i.e., patriarch cardinals) would also be part of the episcopal order, ranking after the six cardinal bishops of the suburbicarian sees (who had been relieved of direct responsibilities for those sees by Pope John XXIII three years earlier). Patriarch cardinals do not receive title of a suburbicarian see, and as such they cannot elect the dean or become dean. There are currently three Eastern Patriarchs who are cardinal bishops:
Is there an answer to this question: How many Western Patriarchs are currently cardinal bishops?

Answer: unanswerable


Question: Manufacturers of devices may have their own proprietary numbering system, for example CK722. Since devices are second-sourced, a manufacturer's prefix (like "MPF" in MPF102, which originally would denote a Motorola FET) now is an unreliable indicator of who made the device. Some proprietary naming schemes adopt parts of other naming schemes, for example a PN2222A is a (possibly Fairchild Semiconductor) 2N2222A in a plastic case (but a PN108 is a plastic version of a BC108, not a 2N108, while the PN100 is unrelated to other xx100 devices).
Is there an answer to this question: What was once an indicator of the devices creator?

Answer: a manufacturer's prefix
