QUES: There are four categories of terra nullius, land that is unclaimed by any state: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies such as the Moon or Mars. In the last three of these, international treaties (the Antarctic Treaty, the United Nations Convention on the Law of the Sea, and the Outer Space Treaty respectively) prevent colonization and potential statehood of any of these uninhabited (and, given current technology, not permanently inhabitable) territories.

Where was the United Nations Convention located?

The Yellowstone River rises on the continental divide near Younts Peak in Wyoming's Teton Wilderness. It flows north through Yellowstone National Park, enters Montana near Gardiner, and passes through the Paradise Valley to Livingston. It then flows northeasterly across the state through Billings, Miles City, Glendive, and Sidney. The Yellowstone joins the Missouri in North Dakota just east of Fort Union. It is the longest undammed, free-flowing river in the contiguous United States, and drains about a quarter of Montana (36,000 square miles (93,000 km2)).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where does the Yellowstone meet the Missouri river?
Ah, so.. North Dakota

Question: Several performing arts groups and facilities are on the University of Michigan's campus, as are museums dedicated to art, archaeology, and natural history and sciences. Founded in 1879, the University Musical Society is an independent performing arts organization that presents over 60 events each year, bringing international artists in music, dance, and theater. Since 2001 Shakespeare in the Arb has presented one play by Shakespeare each June, in a large park near downtown. Regional and local performing arts groups not associated with the university include the Ann Arbor Civic Theatre, the Arbor Opera Theater, the Ann Arbor Symphony Orchestra, the Ann Arbor Ballet Theater, the Ann Arbor Civic Ballet (established in 1954 as Michigan's first chartered ballet company), The Ark, and Performance Network Theatre. Another unique piece of artistic expression in Ann Arbor is the fairy doors. These small portals are examples of installation art and can be found throughout the downtown area.
Try to answer this question if possible: What organization presents over 6 events each year?

QUES: iPod batteries are not designed to be removed or replaced by the user, although some users have been able to open the case themselves, usually following instructions from third-party vendors of iPod replacement batteries. Compounding the problem, Apple initially would not replace worn-out batteries. The official policy was that the customer should buy a refurbished replacement iPod, at a cost almost equivalent to a brand new one. All lithium-ion batteries lose capacity during their lifetime even when not in use (guidelines are available for prolonging life-span) and this situation led to a market for third-party battery replacement kits.
Which iPod component did Apple somewhat inconveniently made non-replaceable?

ANS:
batteries
