Problem: From its discovery in 1846 until the subsequent discovery of Pluto in 1930, Neptune was the farthest known planet. When Pluto was discovered it was considered a planet, and Neptune thus became the penultimate known planet, except for a 20-year period between 1979 and 1999 when Pluto's elliptical orbit brought it closer to the Sun than Neptune. The discovery of the Kuiper belt in 1992 led many astronomers to debate whether Pluto should be considered a planet or as part of the Kuiper belt. In 2006, the International Astronomical Union defined the word "planet" for the first time, reclassifying Pluto as a "dwarf planet" and making Neptune once again the outermost known planet in the Solar System.
What period was Pluto closer to the sun than Neptune?

Answer: between 1979 and 1999

Problem: In 1762, towards the end of the war, French forces attacked St. John's, Newfoundland. If successful, the expedition would have strengthened France's hand at the negotiating table. Although they took St. John's and raided nearby settlements, the French forces were eventually defeated by British troops at the Battle of Signal Hill. This was the final battle of the war in North America, and it forced the French to surrender to Lieutenant Colonel William Amherst. The victorious British now controlled all of eastern North America.
Did the French hold St. John's?

Answer: French forces were eventually defeated by British troops

Problem: Videoconferencing provides students with the opportunity to learn by participating in two-way communication forums. Furthermore, teachers and lecturers worldwide can be brought to remote or otherwise isolated educational facilities. Students from diverse communities and backgrounds can come together to learn about one another, although language barriers will continue to persist. Such students are able to explore, communicate, analyze and share information and ideas with one another. Through videoconferencing, students can visit other parts of the world to speak with their peers, and visit museums and educational facilities. Such virtual field trips can provide enriched learning opportunities to students, especially those in geographically isolated locations, and to the economically disadvantaged. Small schools can use these technologies to pool resources and provide courses, such as in foreign languages, which could not otherwise be offered.
Who can benefit from two-way communication forums?

Answer:
students
