Article: The USB Battery Charging Specification Revision 1.1 (released in 2007) defines a new type of USB port, called the charging port. Contrary to the standard downstream port, for which current draw by a connected portable device can exceed 100 mA only after digital negotiation with the host or hub, a charging port can supply currents between 500 mA and 1.5 A without the digital negotiation. A charging port supplies up to 500 mA at 5 V, up to the rated current at 3.6 V or more, and drops its output voltage if the portable device attempts to draw more than the rated current. The charger port may shut down if the load is too high.

Question: What defines a new type of USB port, called the charging port?
Ans: The USB Battery Charging Specification Revision 1.1


Here is a question about this article: Formal schooling did not start in Hungary until the age of ten. Instead, governesses taught von Neumann, his brothers and his cousins. Max believed that knowledge of languages other than Hungarian was essential, so the children were tutored in English, French, German and Italian. By the age of 8, von Neumann was familiar with differential and integral calculus, but he was particularly interested in history, reading his way through Wilhelm Oncken's Allgemeine Geschichte in Einzeldarstellungen. A copy was contained in a private library Max purchased. One of the rooms in the apartment was converted into a library and reading room, with bookshelves from ceiling to floor.
What is the answer to this question: What languages were Von Neumann and his siblings taught?
****
So... English, French, German and Italian

Problem: Please answer a question about the following article about Armenia:
In the 1988–89 school year, 301 students per 10,000 population were in specialized secondary or higher education, a figure slightly lower than the Soviet average. In 1989 some 58% of Armenians over age fifteen had completed their secondary education, and 14% had a higher education. In the 1990–91 school year, the estimated 1,307 primary and secondary schools were attended by 608,800 students. Another seventy specialized secondary institutions had 45,900 students, and 68,400 students were enrolled in a total of ten postsecondary institutions that included universities. In addition, 35% of eligible children attended preschools. In 1992 Armenia's largest institution of higher learning, Yerevan State University, had eighteen departments, including ones for social sciences, sciences, and law. Its faculty numbered about 1,300 teachers and its student population about 10,000 students. The National Polytechnic University of Armenia is operating since 1933.
How many students did Yerevan State University have in 1992?
A: 10,000


Question: Read this and answer the question

From July to September 1989, Voyager 2 discovered six moons of Neptune. Of these, the irregularly shaped Proteus is notable for being as large as a body of its density can be without being pulled into a spherical shape by its own gravity. Although the second-most-massive Neptunian moon, it is only 0.25% the mass of Triton. Neptune's innermost four moons—Naiad, Thalassa, Despina and Galatea—orbit close enough to be within Neptune's rings. The next-farthest out, Larissa, was originally discovered in 1981 when it had occulted a star. This occultation had been attributed to ring arcs, but when Voyager 2 observed Neptune in 1989, Larissa was found to have caused it. Five new irregular moons discovered between 2002 and 2003 were announced in 2004. A new moon and the smallest yet, S/2004 N 1, was found in 2013. Because Neptune was the Roman god of the sea, Neptune's moons have been named after lesser sea gods.

When was Neptune's moon Larissa discovered? 
Answer:
1981
