input: Please answer the following: Extract the answer to the question from the following context. 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.

output: brightness

Please answer this: Extract the answer to the question from the following context. Question: Who/what was involved in a short attack? Context: Antarctica continued to become more isolated and finally developed a permanent ice cap. Mountain building in western North America continued, and the Alps started to rise in Europe as the African plate continued to push north into the Eurasian plate, isolating the remnants of Tethys Sea. A brief marine incursion marks the early Oligocene in Europe. There appears to have been a land bridge in the early Oligocene between North America and Europe since the faunas of the two regions are very similar. During the Oligocene, South America was finally detached from Antarctica and drifted north toward North America. It also allowed the Antarctic Circumpolar Current to flow, rapidly cooling the continent.

Problem: Extract the answer to the question from the following context. Question: What is Han cursive known as today? Context: Contrary to the popular belief of there being only one script per period, there were in fact multiple scripts in use during the Han period. Although mature clerical script, also called (bafen) script, was dominant at that time, an early type of cursive script was also in use by the Han by at least as early as 24 BC (during the very late Western Han period),[b] incorporating cursive forms popular at the time, well as many elements from the vulgar writing of the Warring State of Qin. By around the time of the Eastern Jin dynasty, this Han cursive became known as zhangcao (also known as / licao today), or in English sometimes clerical cursive, ancient cursive, or draft cursive. Some believe that the name, based on zhang meaning "orderly", arose because the script was a more orderly form of cursive than the modern form, which emerged during the Eastern Jin dynasty and is still in use today, called jincao or "modern cursive".

A: licao

Problem: Given the question: Extract the answer to the question from the following context. Question: A judge works for the? Context: Mali's constitution provides for an independent judiciary, but the executive continues to exercise influence over the judiciary by virtue of power to appoint judges and oversee both judicial functions and law enforcement. Mali's highest courts are the Supreme Court, which has both judicial and administrative powers, and a separate Constitutional Court that provides judicial review of legislative acts and serves as an election arbiter. Various lower courts exist, though village chiefs and elders resolve most local disputes in rural areas.

input question: Extract the answer to the question from the following context. Question: Where does the name derive? Context: A bantam is a small variety of domestic chicken, either a miniature version of a member of a standard breed, or a "true bantam" with no larger counterpart. The name derives from the town of Bantam in Java where European sailors bought the local small chickens for their shipboard supplies. Bantams may be a quarter to a third of the size of standard birds and lay similarly small eggs. They are kept by small-holders and hobbyists for egg production, use as broody hens, ornamental purposes, and showing.???
output answer: Bantam in Java where European sailors bought the local small chickens for their shipboard supplies

input question: Extract the answer to the question from the following context. Question: What is the difference? Context: The storage in sensory memory and short-term memory generally has a strictly limited capacity and duration, which means that information is not retained indefinitely. By contrast, long-term memory can store much larger quantities of information for potentially unlimited duration (sometimes a whole life span). Its capacity is immeasurable. For example, given a random seven-digit number we may remember it for only a few seconds before forgetting, suggesting it was stored in our short-term memory. On the other hand, we can remember telephone numbers for many years through repetition; this information is said to be stored in long-term memory.???
output answer:
long-term memory can store much larger quantities of information for potentially unlimited duration
