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.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 361, after the death of Emperor Constantius, shortly followed by the murder of the very unpopular Bishop George, Athanasius returned to his patriarchate. The following year he convened a council at Alexandria, and presided over it with Eusebius of Vercelli. Athanasius appealed for unity among all those who had faith in Christianity, even if they differed on matters of terminology. This prepared the groundwork for his definition of the orthodox doctrine of the Trinity. However, the council also was directed against those who denied the divinity of the Holy Spirit, the human soul of Christ, and Christ's divinity. Mild measures were agreed on for those heretic bishops who repented, but severe penance was decreed for the chief leaders of the major heresies.
When did Athanasius return to his position as pope?
A: unanswerable

Question: Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. The city was originally laid out in a grid pattern with the North Carolina State Capitol in Union Square at the center. In the United States Civil War the city was spared from any significant battle, only falling in the closing days of the war, though it did not escape the economic hardships that plagued the rest of the American South during the Reconstruction Era. The twentieth century saw the opening of the Research Triangle Park in 1959, and with the jobs it created the region and city saw a large influx of population, making it one of the fastest growing communities in the United States by the early 21st century.
Is there an answer to this question: What happened in the 20th century?

Answer: Research Triangle Park
