input: Please answer the following: Question: "Which of the following is easier for humans to perceive: small differences in color or in brightness?" Context: "Video data may be represented as a series of still image frames. The sequence of frames contains spatial and temporal redundancy that video compression algorithms attempt to eliminate or code in a smaller size. Similarities can be encoded by only storing differences between frames, or by using perceptual features of human vision. For example, small differences in color are more difficult to perceive than are changes in brightness. Compression algorithms can average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression. Some of these methods are inherently lossy while others may preserve all relevant information from the original, uncompressed video." Answer:
++++++++++
output: brightness

input: Please answer the following: Question: "Who had the least soldiers in the Battle of Chosin Reservoir?" Context: "On 25 November at the Korean western front, the PVA 13th Army Group attacked and overran the ROK II Corps at the Battle of the Ch'ongch'on River, and then decimated the US 2nd Infantry Division on the UN forces' right flank. The UN Command retreated; the U.S. Eighth Army's retreat (the longest in US Army history) was made possible because of the Turkish Brigade's successful, but very costly, rear-guard delaying action near Kunuri that slowed the PVA attack for two days (2729 November). On 27 November at the Korean eastern front, a U.S. 7th Infantry Division Regimental Combat Team (3,000 soldiers) and the U.S. 1st Marine Division (12,00015,000 marines) were unprepared for the PVA 9th Army Group's three-pronged encirclement tactics at the Battle of Chosin Reservoir, but they managed to escape under Air Force and X Corps support firealbeit with some 15,000 collective casualties." Answer:

output: U.S. 7th Infantry Division Regimental Combat Team

input: Please answer the following: Question: "What underwent major alterations in the Byzantine lands and the land now known as Iran?" Context: "Religious beliefs in the Eastern Empire and Persia were in flux during the late 6th and early 7th centuries. Judaism was an active proselytising faith, and at least one Arab political leader converted to it.[J] Christianity had active missions competing with the Persians' Zoroastrianism in seeking converts, especially among residents of the Arabian Peninsula. All these strands came together with the emergence of Islam in Arabia during the lifetime of Muhammad (d. 632). After his death, Islamic forces conquered much of the Eastern Empire and Persia, starting with Syria in 634635 and reaching Egypt in 640641, Persia between 637 and 642, North Africa in the later 7th century, and the Iberian Peninsula in 711. By 714, Islamic forces controlled much of the peninsula in a region they called Al-Andalus." Answer:
++++++++++
output: Religious beliefs

input: Please answer the following: Question: "Tribes cannot impact?" Context: "Thirty-nine Native American tribal governments are based in Oklahoma, each holding limited powers within designated areas. While Indian reservations typical in most of the United States are not present in Oklahoma, tribal governments hold land granted during the Indian Territory era, but with limited jurisdiction and no control over state governing bodies such as municipalities and counties. Tribal governments are recognized by the United States as quasi-sovereign entities with executive, judicial, and legislative powers over tribal members and functions, but are subject to the authority of the United States Congress to revoke or withhold certain powers. The tribal governments are required to submit a constitution and any subsequent amendments to the United States Congress for approval." Answer:
++++++++++
output:
state governing bodies such as municipalities and counties
