Here is a question about this article: The Mahayana sutras are a very broad genre of Buddhist scriptures that the Mahayana Buddhist tradition holds are original teachings of the Buddha. Some adherents of Mahayana accept both the early teachings (including in this the Sarvastivada Abhidharma, which was criticized by Nagarjuna and is in fact opposed to early Buddhist thought) and the Mahayana sutras as authentic teachings of Gautama Buddha, and claim they were designed for different types of persons and different levels of spiritual understanding.
What is the answer to this question: What is a very broad genre of Buddhist scripture?
****
So... Mahayana sutras


Here is a question about this article: After secretly crossing the Yalu River on 19 October, the PVA 13th Army Group launched the First Phase Offensive on 25 October, attacking the advancing UN forces near the Sino-Korean border. This military decision made solely by China changed the attitude of the Soviet Union. Twelve days after Chinese troops entered the war, Stalin allowed the Soviet Air Force to provide air cover, and supported more aid to China. After decimating the ROK II Corps at the Battle of Onjong, the first confrontation between Chinese and U.S. military occurred on 1 November 1950; deep in North Korea, thousands of soldiers from the PVA 39th Army encircled and attacked the U.S. 8th Cavalry Regiment with three-prong assaults—from the north, northwest, and west—and overran the defensive position flanks in the Battle of Unsan. The surprise assault resulted in the UN forces retreating back to the Ch'ongch'on River, while the Chinese unexpectedly disappeared into mountain hideouts following victory. It is unclear why the Chinese did not press the attack and follow up their victory.
What is the answer to this question: When did the Chinese and US military have their first confrontation in Korea?
****
So... 1 November 1950


Here is a question about this article: Humans would also have derived enormous benefit from the dogs associated with their camps. For instance, dogs would have improved sanitation by cleaning up food scraps. Dogs may have provided warmth, as referred to in the Australian Aboriginal expression "three dog night" (an exceptionally cold night), and they would have alerted the camp to the presence of predators or strangers, using their acute hearing to provide an early warning.
What is the answer to this question: What did a dog's good hearing help humans with?
****
So...
early warning.
