Problem: Dog:

Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli. As the oldest domesticated species, with estimates ranging from 9,000–30,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans and they are uniquely attuned to our behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the otherwise humble domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes. Rather, these skills parallel some of the social-cognitive skills of human children.

Dogs are estimated to be domesticated as far back as what date range of years on the calendar?

Problem: Estonian language:

The birth of native Estonian literature was in 1810 to 1820 when the patriotic and philosophical poems by Kristjan Jaak Peterson were published. Peterson, who was the first student at the then German-language University of Dorpat to acknowledge his Estonian origin, is commonly regarded as a herald of Estonian national literature and considered the founder of modern Estonian poetry. His birthday on March 14 is celebrated in Estonia as the Mother Tongue Day. A fragment from Peterson's poem "Kuu" expresses the claim reestablishing the birthright of the Estonian language:

What university did Peterson attend?

Problem: United States Air Force:

USAF rank is divided between enlisted airmen, non-commissioned officers, and commissioned officers, and ranges from the enlisted Airman Basic (E-1) to the commissioned officer rank of General (O-10). Enlisted promotions are granted based on a combination of test scores, years of experience, and selection board approval while officer promotions are based on time-in-grade and a promotion selection board. Promotions among enlisted personnel and non-commissioned officers are generally designated by increasing numbers of insignia chevrons. Commissioned officer rank is designated by bars, oak leaves, a silver eagle, and anywhere from one to four stars (one to five stars in war-time).[citation needed]

What groups is the USAF rank divided amoung?
