Teacher: Now, understand the problem? Solve this instance: Question: How old is the magazine that Sapolsky wrote for in 1990? Passage 1:By 1968 regular air force military airlift squadrons were operating the Lockheed C-141 Starlifter, while reserve heavy airlift units still flew the obsolete Douglas C-124 Globemaster II. As the Globemaster was retired, Air Force Reserve formed associate units with the C-141. In this program reserve units flew and maintained aircraft owned by an associated regular unit. On 25 March 1968, the 730th moved to Norton Air Force Base without aircraft as an associate of the active duty 63d Military Airlift Wing. In 1973, Air Force Reserve inactivated its reserve associate groups and the squadron was assigned directly to the 445th Military Airlift Wing. Missions the 730th has flown included humanitarian relief, aeromedical flights, and airdrops of supplies and paratroopers. In 1989, the squadron participated in Operation Just Cause, the incursion into Panama that replaced Manuel Noriega as its leader.
Passage 2:As a neuroendocrinologist, he has focused his research on issues of stress and neuronal degeneration, as well as on the possibilities of gene therapy strategies for protecting susceptible neurons from disease. Currently, he is working on gene transfer techniques to strengthen neurons against the disabling effects of glucocorticoids. Each year, Sapolsky spends time in Kenya studying a population of wild baboons in order to identify the sources of stress in their environment, and the relationship between personality and patterns of stress-related disease in these animals. More specifically, Sapolsky studies the cortisol levels between the alpha male and female and the subordinates to determine stress level. An early but still relevant example of his studies of olive baboons is to be found in his 1990 Scientific American article, "Stress in the Wild". He has also written about neurological impairment and the insanity defense within the American legal system.
Passage 3:Keshilla (literally meaning "Council" in Albanian; ) was an Albanian administration in Thesprotia, Greece, during the Axis occupation of Greece (1941-1944). It was set up during the Fascist Italian occupation with the aim of annexing the Greek region into a greater Albanian state and continued its operations under Nazi German occupation until the defeat of Axis Powers and the end of World War II. This initiative was undertaken by the Cham Albanian leaders of the Dino family, in particular the brothers Nuri and Mazar Dino and received support by the majority of the Cham community, who had collaborated with the Axis. The policy of ethnic cleansing perpetrated by the Keshilla and other paramilitary organisations under the Dino clan was used by EDES resistance forces at the end of the war to expel the Muslim Cham community from the region, with the exception of small groups who had not followed them.
