Context and question: Both intensive and free-range farming have animal welfare concerns. In intensive systems, cannibalism, feather pecking and vent pecking can be common, with some farmers using beak trimming as a preventative measure. Diseases can also be common and spread rapidly through the flock. In extensive systems, the birds are exposed to adverse weather conditions and are vulnerable to predators and disease-carrying wild birds. Barn systems have been found to have the worst bird welfare. In Southeast Asia, a lack of disease control in free-range farming has been associated with outbreaks of avian influenza.
How is the spread of the avian flu related to the conditions in which chickens are kept?
Answer: In Southeast Asia, a lack of disease control in free-range farming has been associated with outbreaks of avian influenza.
Context and question: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.
What happens outside the 1/1000 second to 1/second exposure range?
Answer: reciprocity failure
Context and question: On January 7, 2012, Beyoncé gave birth to a daughter, Blue Ivy Carter, at Lenox Hill Hospital in New York under heavy security. Two days later, Jay Z released "Glory", a song dedicated to their child, on his website Lifeandtimes.com. The song detailed the couple's pregnancy struggles, including a miscarriage Beyoncé suffered before becoming pregnant with Blue Ivy. Blue Ivy's cries are included at the end of the song, and she was officially credited as "B.I.C." on it. At two days old, she became the youngest person ever to appear on a Billboard chart when "Glory" debuted on the Hot R&B/Hip-Hop Songs chart.
At what hospital was the baby delivered?
Answer:
Lenox Hill Hospital
