Problem: Cognitive neuroscientists consider memory as the retention, reactivation, and reconstruction of the experience-independent internal representation. The term of internal representation implies that such definition of memory contains two components: the expression of memory at the behavioral or conscious level, and the underpinning physical neural changes (Dudai 2007). The latter component is also called engram or memory traces (Semon 1904). Some neuroscientists and psychologists mistakenly equate the concept of engram and memory, broadly conceiving all persisting after-effects of experiences as memory; others argue against this notion that memory does not exist until it is revealed in behavior or thought (Moscovitch 2007).

Problem: Broadband wireless services were offered by both dial up and non-dial up ISPs in major cities, such as Mogadishu, Bosaso, Hargeisa, Galkayo and Kismayo. Pricing ranged from $150 to $300 a month for unlimited internet access, with bandwidth rates of 64 kbit/s up and down. The main patrons of these wireless services were scholastic institutions, corporations, and UN, NGO and diplomatic missions. Mogadishu had the biggest subscriber base nationwide and was also the headquarters of the largest wireless internet services, among which were Dalkom (Wanaag HK), Orbit, Unitel and Webtel.

Problem: Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the Appalachian Highlands physiographic division as consisting of thirteen provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, Saint Lawrence Valley, Appalachian Plateaus, New England province, and the Adirondack provinces. A common variant definition does not include the Adirondack Mountains, which geologically belong to the Grenville Orogeny and have a different geological history from the rest of the Appalachians.
What has a similar geological history to the Appalachians?
