Problem: Hebb distinguished between short-term and long-term memory. He postulated that any memory that stayed in short-term storage for a long enough time would be consolidated into a long-term memory. Later research showed this to be false. Research has shown that direct injections of cortisol or epinephrine help the storage of recent experiences. This is also true for stimulation of the amygdala. This proves that excitement enhances memory by the stimulation of hormones that affect the amygdala. Excessive or prolonged stress (with prolonged cortisol) may hurt memory storage. Patients with amygdalar damage are no more likely to remember emotionally charged words than nonemotionally charged ones. The hippocampus is important for explicit memory. The hippocampus is also important for memory consolidation. The hippocampus receives input from different parts of the cortex and sends its output out to different parts of the brain also. The input comes from secondary and tertiary sensory areas that have processed the information a lot already. Hippocampal damage may also cause memory loss and problems with memory storage. This memory loss includes, retrograde amnesia which is the loss of memory for events that occurred shortly before the time of brain damage.

Problem: Most Western and Commonwealth militaries integrate air defence purely with the traditional services, of the military (i.e. army, navy and air force), as a separate arm or as part of artillery. In the United States Army for instance, air defence is part of the artillery arm, while in the Pakistan Army, it was split off from Artillery to form a separate arm of its own in 1990. This is in contrast to some (largely communist or ex-communist) countries where not only are there provisions for air defence in the army, navy and air force but there are specific branches that deal only with the air defence of territory, for example, the Soviet PVO Strany. The USSR also had a separate strategic rocket force in charge of nuclear intercontinental ballistic missiles.
Air defence in the US Army is part of what arm?

Answer: artillery arm


Problem: The city proper is home to less than one-thirteenth of the population of South Florida. Miami is the 42nd-most populous city in the United States. The Miami metropolitan area, which includes Miami-Dade, Broward and Palm Beach counties, had a combined population of more than 5.5 million people, ranked seventh largest in the United States, and is the largest metropolitan area in the Southeastern United States. As of 2008[update], the United Nations estimates that the Miami Urban Agglomeration is the 44th-largest in the world.
Along with Palm Beach and Miami-Dade, what county is part of the Miami-Dade metropolitan area?
