Input: Read this: 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.
Question: Where are the biggest population of Puerto Ricans on the mainland?

Output: many Puerto Ricans have migrated to New York City, Orlando, Philadelphia, and other areas of the Eastern United States

Input: Read this: Before creation of Warsaw Pact, fearing Germany rearmed, Czechoslovak leadership sought to create security pact with East Germany and Poland. These states protested strongly against re-militarization of West Germany. The Warsaw Pact was primarily put in place as a consequence of the rearming of West Germany inside NATO. Soviet leaders, as many European countries in both western and eastern side, feared Germany being once again a military power as a direct threat and German militarism remained a fresh memory among Soviets and Eastern Europeans. As Soviet Union had already bilateral treaties with all of its eastern satellites, the Pact has been long considered 'superfluous', and because of the rushed way in which it was conceived, NATO officials labeled it as a 'cardboard castle'. Previously, in March 1954, the USSR, fearing the restoration of German Militarism in West Germany, requested admission to NATO.
Question: What officials said the Pact was a "superfluous castle"?

Output: unanswerable

Input: Read this: Annelids are members of the protostomes, one of the two major superphyla of bilaterian animals the other is the deuterostomes, which includes vertebrates. Within the protostomes, annelids used to be grouped with arthropods under the super-group Articulata ("jointed animals"), as segmentation is obvious in most members of both phyla. However, the genes that drive segmentation in arthropods do not appear to do the same in annelids. Arthropods and annelids both have close relatives that are unsegmented. It is at least as easy to assume that they evolved segmented bodies independently as it is to assume that the ancestral protostome or bilaterian was segmented and that segmentation disappeared in many descendant phyla. The current view is that annelids are grouped with molluscs, brachiopods and several other phyla that have lophophores (fan-like feeding structures) and/or trochophore larvae as members of Lophotrochozoa. Bryzoa may be the most basal phylum (the one that first became distinctive) within the Lophotrochozoa, and the relationships between the other members are not yet known. Arthropods are now regarded as members of the Ecdysozoa ("animals that molt"), along with some phyla that are unsegmented.
Question: What are lophophores?

Output: fan-like feeding structures
