Problem: Guam:

In 1899, the local postage stamps were overprinted "Guam" as was done for the other former Spanish colonies, but this was discontinued shortly thereafter and regular U.S. postage stamps have been used ever since. Because Guam is also part of the U.S. Postal System (postal abbreviation: GU, ZIP code range: 9691096932), mail to Guam from the U.S. mainland is considered domestic and no additional charges are required. Private shipping companies, such as FedEx, UPS, and DHL, however, have no obligation to do so, and do not regard Guam as domestic.

Which private shipping company charges more to ship packages to Guam?

Problem: A series of new editors-in-chief oversaw the company during another slow time for the industry. Once again, Marvel attempted to diversify, and with the updating of the Comics Code achieved moderate to strong success with titles themed to horror (The Tomb of Dracula), martial arts, (Shang-Chi: Master of Kung Fu), sword-and-sorcery (Conan the Barbarian, Red Sonja), satire (Howard the Duck) and science fiction (2001: A Space Odyssey, "Killraven" in Amazing Adventures, Battlestar Galactica, Star Trek, and, late in the decade, the long-running Star Wars series). Some of these were published in larger-format black and white magazines, under its Curtis Magazines imprint. Marvel was able to capitalize on its successful superhero comics of the previous decade by acquiring a new newsstand distributor and greatly expanding its comics line. Marvel pulled ahead of rival DC Comics in 1972, during a time when the price and format of the standard newsstand comic were in flux. Goodman increased the price and size of Marvel's November 1971 cover-dated comics from 15 cents for 36 pages total to 25 cents for 52 pages. DC followed suit, but Marvel the following month dropped its comics to 20 cents for 36 pages, offering a lower-priced product with a higher distributor discount.
How much did DC lower the price of its comics by?

However, from 1971 to 1975, NBA teams played preseason exhibitions against American Basketball Association teams. In the early days of the NBA, league clubs sometimes challenged the legendary barnstorming Harlem Globetrotters, with mixed success. The NBA has played preseason games in Europe and Asia. In the 2006 and 2007 seasons, the NBA and the primary European club competition, the Euroleague, conducted a preseason tournament featuring two NBA teams and the finalists from that year's Euroleague.[citation needed] In the 1998-99 and 2011-12 seasons, teams were limited to only two preseason games due to lockouts.

Context and question: The remote location of the islands makes transport to the outside world difficult. Lacking an airport, the islands can be reached only by sea. Fishing boats from South Africa service the islands eight or nine times a year. The RMS Saint Helena used to connect the main island to St Helena and South Africa once each year during its January voyage, but has done so only twice in the last few years, in 2006 and 2011. The wider territory has access to air travel with Ascension island served by RAF Ascension Island and a new airport, financed by the United Kingdom government, under construction on St Helena and due for completion in 2016. There is however no direct, regular service to Tristan da Cunha itself from either location. The harbour at Edinburgh of the Seven Seas is called Calshot Harbour, named after the place in Hampshire where the islanders temporarily stayed during the volcanic eruption.
How many times a year do airplanes service the area?

Question: Somalia established its first ISP in 1999, one of the last countries in Africa to get connected to the Internet. According to the telecommunications resource Balancing Act, growth in internet connectivity has since then grown considerably, with around 53% of the entire nation covered as of 2009. Both internet commerce and telephony have consequently become among the quickest growing local businesses.
Is there an answer to this question: Who was the first African country to get internet?

The Ming dynasty granted titles to lamas of schools such as the Karmapa Kargyu, but the latter had previously declined Mongol invitations to receive titles. When the Ming Yongle Emperor invited Je Tsongkhapa (13571419), founder of the Gelug school, to come to the Ming court and pay tribute, the latter declined. Wang and Nyima write that this was due to old age and physical weakness, and also because of efforts being made to build three major monasteries. Chen Qingying states that Tsongkhapa wrote a letter to decline the Emperor's invitation, and in this reply, Tsongkhapa wrote:
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who wrote the letter declining the Emperor's invitation?

Tsongkhapa
