Input: Article: The original NAS Bermuda on the west side of the island, a seaplane base until the mid-1960s, was designated as the Naval Air Station Bermuda Annex.

An additional US Navy compound known as Naval Facility Bermuda (NAVFAC Bermuda), a SOSUS station, was located to the west of the Annex near a Canadian Forces communications facility. Although leased for 99 years, US forces withdrew in 1995, as part of the wave of base closures following the end of the Cold War.

Now answer this question: What was the NAS primarily a base for?

Output: seaplane


Article: Short-term memory is also known as working memory. Short-term memory allows recall for a period of several seconds to a minute without rehearsal. Its capacity is also very limited: George A. Miller (1956), when working at Bell Laboratories, conducted experiments showing that the store of short-term memory was 7±2 items (the title of his famous paper, "The magical number 7±2"). Modern estimates of the capacity of short-term memory are lower, typically of the order of 4–5 items; however, memory capacity can be increased through a process called chunking. For example, in recalling a ten-digit telephone number, a person could chunk the digits into three groups: first, the area code (such as 123), then a three-digit chunk (456) and lastly a four-digit chunk (7890). This method of remembering telephone numbers is far more effective than attempting to remember a string of 10 digits; this is because we are able to chunk the information into meaningful groups of numbers. This may be reflected in some countries in the tendency to display telephone numbers as several chunks of two to four numbers.

Question: How much information can one store and recall in short-term memory?
Ans: capacity is also very limited
