John XXIII died of peritonitis caused by a perforated stomach at 19:49 local time on 3 June 1963 at the age of 81, ending a historic pontificate of four years and seven months. He died just as a Mass for him finished in Saint Peter's Square below, celebrated by Luigi Traglia. After he died, his brow was ritually tapped to see if he was dead, and those with him in the room said prayers. Then the room was illuminated, thus informing the people of what had happened. He was buried on 6 June in the Vatican grottos. Two wreaths, placed on the two sides of his tomb, were donated by the prisoners of the Regina Coeli prison and the Mantova jail in Verona. On 22 June 1963, one day after his friend and successor Pope Paul VI was elected, the latter prayed at his tomb.
When did John XXIII pray at Luigi Traglia's tomb?
A: unanswerable

40°48′27″N 73°57′18″W﻿ / ﻿40.8076°N 73.9549°W﻿ / 40.8076; -73.9549 120th Street traverses the neighborhoods of Morningside Heights, Harlem, and Spanish Harlem. It begins on Riverside Drive at the Interchurch Center. It then runs east between the campuses of Barnard College and the Union Theological Seminary, then crosses Broadway and runs between the campuses of Columbia University and Teacher's College. The street is interrupted by Morningside Park. It then continues east, eventually running along the southern edge of Marcus Garvey Park, passing by 58 West, the former residence of Maya Angelou. It then continues through Spanish Harlem; when it crosses Pleasant Avenue it becomes a two‑way street and continues nearly to the East River, where for automobiles, it turns north and becomes Paladino Avenue, and for pedestrians, continues as a bridge across FDR Drive.
On which road does 120th Street begin?
A: Riverside Drive

The capacitance of certain capacitors decreases as the component ages. In ceramic capacitors, this is caused by degradation of the dielectric. The type of dielectric, ambient operating and storage temperatures are the most significant aging factors, while the operating voltage has a smaller effect. The aging process may be reversed by heating the component above the Curie point. Aging is fastest near the beginning of life of the component, and the device stabilizes over time. Electrolytic capacitors age as the electrolyte evaporates. In contrast with ceramic capacitors, this occurs towards the end of life of the component.
What value of some capacitors decreases with age?
A: The capacitance

Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed "real ale" by the CAMRA organisation. Typically, when a cask arrives in a pub, it is placed horizontally on a frame called a "stillage" which is designed to hold it steady and at the right angle, and then allowed to cool to cellar temperature (typically between 11–13 °C or 52–55 °F), before being tapped and vented—a tap is driven through a (usually rubber) bung at the bottom of one end, and a hard spile or other implement is used to open a hole in the side of the cask, which is now uppermost. The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period to "drop" (clear) again, as well as to fully condition—this period can take anywhere from several hours to several days. At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass.
How long does it take for sediment to settle and clear after a cask ale has been tapped?
A:
from several hours to several days
