Article: The evolution of Proto-Greek should be considered within the context of an early Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages. The characteristically Greek representation of word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language, which also seems to share some other phonological and morphological peculiarities of Greek; this has led some linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.

Question: How much evidence of the link between the languages is currently available ?
Ans: linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.


Article: New York City's food culture includes a variety of international cuisines influenced by the city's immigrant history. Central European and Italian immigrants originally made the city famous for bagels, cheesecake, and New York-style pizza, while Chinese and other Asian restaurants, sandwich joints, trattorias, diners, and coffeehouses have become ubiquitous. Some 4,000 mobile food vendors licensed by the city, many immigrant-owned, have made Middle Eastern foods such as falafel and kebabs popular examples of modern New York street food. The city is also home to nearly one thousand of the finest and most diverse haute cuisine restaurants in the world, according to Michelin. The New York City Department of Health and Mental Hygiene assigns letter grades to the city's 24,000 restaurants based upon their inspection results.

Question: How many restaurants are there in NYC?
Ans: 24,000


Article: During the Baroque era, keyboard music played on the harpsichord and pipe organ became increasingly popular, and the violin family of stringed instruments took the form generally seen today. Opera as a staged musical drama began to differentiate itself from earlier musical and dramatic forms, and vocal forms like the cantata and oratorio became more common. Vocalists began adding embellishments to melodies. Instrumental ensembles began to distinguish and standardize by size, giving rise to the early orchestra for larger ensembles, with chamber music being written for smaller groups of instruments where parts are played by individual (instead of massed) instruments. The concerto as a vehicle for solo performance accompanied by an orchestra became widespread, although the relationship between soloist and orchestra was relatively simple.

Question: What became more common during the Baroque era?
Ans: vocal forms


Article: No single feature distinguishes Annelids from other invertebrate phyla, but they have a distinctive combination of features. Their bodies are long, with segments that are divided externally by shallow ring-like constrictions called annuli and internally by septa ("partitions") at the same points, although in some species the septa are incomplete and in a few cases missing. Most of the segments contain the same sets of organs, although sharing a common gut, circulatory system and nervous system makes them inter-dependent. Their bodies are covered by a cuticle (outer covering) that does not contain cells but is secreted by cells in the skin underneath, is made of tough but flexible collagen and does not molt – on the other hand arthropods' cuticles are made of the more rigid α-chitin, and molt until the arthropods reach their full size. Most annelids have closed circulatory systems, where the blood makes its entire circuit via blood vessels.

Question: What externally divides annelids' segments?
Ans:
shallow ring-like constrictions called annuli
