Problem: Please answer a question about the following article about Data compression:
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.
What can average a color across similar areas to reduce space?
A: Compression algorithms

Question: Read this and answer the question

Daphne was a nymph, daughter of the river god Peneus, who had scorned Apollo. The myth explains the connection of Apollo with (daphne), the laurel whose leaves his priestess employed at Delphi. In Ovid's Metamorphoses, Phoebus Apollo chaffs Cupid for toying with a weapon more suited to a man, whereupon Cupid wounds him with a golden dart; simultaneously, however, Cupid shoots a leaden arrow into Daphne, causing her to be repulsed by Apollo. Following a spirited chase by Apollo, Daphne prays to her father, Peneus, for help, and he changes her into the laurel tree, sacred to Apollo.

Who is Daphne's father?
Answer: Peneus

Problem: Under the 1963 constitution, Massamba-Debat was elected President for a five-year term. During Massamba-Debat's term in office the regime adopted "scientific socialism" as the country's constitutional ideology. In 1965, Congo established relations with the Soviet Union, the People's Republic of China, North Korea and North Vietnam. Massamba-Debat's regime also invited several hundred Cuban army troops into the country to train his party's militia units and these troops helped his government survive a coup in 1966 led by paratroopers loyal to future President Marien Ngouabi. Nevertheless, Massamba-Debat was unable to reconcile various institutional, tribal and ideological factions within the country and his regime ended abruptly with a bloodless coup d'etat in September 1968.
Who became president of the Congo in 1963?
The answer is the following: Massamba-Debat

In Germany, groups such as Einsturzende Neubauten developed a unique style of industrial music, utilizing avant-garde noise, homemade instruments and found objects. Members of that group would later go on to collaborate with members of the Birthday Party. In Brazil, the post-punk scene grew after the generation of Brasilia rock with bands such as Legiao Urbana, Capital Inicial and Plebe Rude and then the opening of the music club Madame Sata in Sao Paulo, with acts like Cabine C, Titas, Patife Band, Fellini and Mercenarias, as documented on compilations like The Sexual Life of the Savages and the Nao Wave/Nao Sao Paulo series, released in the UK, Germany and Brazil, respectively.[citation needed]
What type of music included noise, homemade instruments, and randomly found objects?
industrial

Input: Anti-aircraft warfare
Service trials demonstrated another problem however: that ranging and tracking the new high-speed targets was almost impossible. At short range, the apparent target area is relatively large, the trajectory is flat and the time of flight is short, allowing to correct lead by watching the tracers. At long range, the aircraft remains in firing range for a long time, so the necessary calculations can in theory be done by slide rules - though, because small errors in distance cause large errors in shell fall height and detonation time, exact ranging is crucial. For the ranges and speeds that the Bofors worked at, neither answer was good enough.

What small errors caused large errors in shell fall height and the time until exploding?
Output: small errors in distance

Problem: Please answer a question about the following article about Black people:
Black people is a term used in certain countries, often in socially based systems of racial classification or of ethnicity, to describe persons who are perceived to be dark-skinned compared to other given populations. As such, the meaning of the expression varies widely both between and within societies, and depends significantly on context. For many other individuals, communities and countries, "black" is also perceived as a derogatory, outdated, reductive or otherwise unrepresentative label, and as a result is neither used nor defined.
Can the term "black people" have different meanings?
A:
the meaning of the expression varies widely both between and within societies, and depends significantly on context.
