Input: Read this: In the 19th century, a house near Ephesus in Turkey was found, based on the visions of Anne Catherine Emmerich, an Augustinian nun in Germany. It has since been visited as the House of the Virgin Mary by Roman Catholic pilgrims who consider it the place where Mary lived until her assumption. The Gospel of John states that Mary went to live with the Disciple whom Jesus loved,[Jn 19:27] identified as John the Evangelist.[citation needed] Irenaeus and Eusebius of Caesarea wrote in their histories that John later went to Ephesus, which may provide the basis for the early belief that Mary also lived in Ephesus with John.
Question: In what century did Mary live in Ephesus with John?

Output: unanswerable

QUES: Ducks are medium-sized aquatic birds with broad bills, eyes on the side of the head, fairly long necks, short legs set far back on the body, and webbed feet. Males, known as drakes, are often larger than females (simply known as ducks) and are differently coloured in some breeds. Domestic ducks are omnivores, eating a variety of animal and plant materials such as aquatic insects, molluscs, worms, small amphibians, waterweeds, and grasses. They feed in shallow water by dabbling, with their heads underwater and their tails upended. Most domestic ducks are too heavy to fly, and they are social birds, preferring to live and move around together in groups. They keep their plumage waterproof by preening, a process that spreads the secretions of the preen gland over their feathers.

Why can't you identify a duck from other poultry?

QUES: To allow for greater movement while dancing and singing, Madonna was one of the earliest adopters of hands-free radio-frequency headset microphones, with the headset fastened over the ears or the top of the head, and the microphone capsule on a boom arm that extended to the mouth. Because of her prominent usage, the microphone design came to be known as the "Madonna mic". Metz noted that Madonna represents a paradox as she is often perceived as living her whole life as a performance. While her big-screen performances are panned, her live performances are critical successes. Madonna was the first artist to have her concert tours as reenactment of her music videos. Author Elin Diamond explained that reciprocally, the fact that images from Madonna's videos can be recreated in a live setting enhances the realism of the original videos. Thus her live performances have become the means by which mediatized representations are naturalized. Taraborrelli said that encompassing multimedia, latest technology and sound systems, Madonna's concerts and live performances are deemed as "extravagant show piece, a walking art show."
What did Madonna use in her concerts?

ANS: hands-free radio-frequency headset microphones

Problem: Under the Koppen climate classification, using the 0 C (32 F) coldest month (January) isotherm, New York City itself experiences a humid subtropical climate (Cfa) and is thus the northernmost major city on the North American continent with this categorization. The suburbs to the immediate north and west lie in the transition zone from a humid subtropical (Cfa) to a humid continental climate (Dfa). The area averages 234 days with at least some sunshine annually, and averages 57% of possible sunshine annually, accumulating 2,535 hours of sunshine per annum. The city falls under USDA 7b Plant Hardiness zone.
How many hours of sunshine does New York receive every year?
---
Answer:
2,535
