Article: The USB Battery Charging Specification Revision 1.2 (released in 2010) makes clear that there are safety limits to the rated current at 5 A coming from USB 2.0. On the other hand, several changes are made and limits are increasing including allowing 1.5 A on charging downstream ports for unconfigured devices, allowing high speed communication while having a current up to 1.5 A, and allowing a maximum current of 5 A. Also, revision 1.2 removes support for USB ports type detection via resistive detection mechanisms.

Question: What does the USB Battery Charging Specification Revision 1.2 make clear of?
Ans: there are safety limits to the rated current at 5 A coming from USB 2.0

Article: French cooperation was deemed necessary to the campaign, and Eisenhower encountered a "preposterous situation" with the multiple rival factions in France. His primary objective was to move forces successfully into Tunisia, and intending to facilitate that objective, he gave his support to Francois Darlan as High Commissioner in North Africa, despite Darlan's previous high offices of state in Vichy France and his continued role as commander-in-chief of the French armed forces. The Allied leaders were "thunderstruck" by this from a political standpoint, though none of them had offered Eisenhower guidance with the problem in the course of planning the operation. Eisenhower was severely criticized for the move. Darlan was assassinated on December 24 by Fernand Bonnier de La Chapelle. Eisenhower did not take action to prevent the arrest and extrajudicial execution of Bonnier de La Chapelle by associates of Darlan acting without authority from either Vichy or the Allies, considering it a criminal rather than a military matter. Eisenhower later appointed General Henri Giraud as High Commissioner, who had been installed by the Allies as Darlan's commander-in-chief, and who had refused to postpone the execution.

Question: Who served as High Commissioner of North Africa after Darlan's death?
Ans: Henri Giraud

Article: 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.

Question: What harsh measures do farmers use to prevent the chickens from harming themselves or others?
Ans:
some farmers using beak trimming as a preventative measure
