Input: Read this: A "tag" in an audio file is a section of the file that contains metadata such as the title, artist, album, track number or other information about the file's contents. The MP3 standards do not define tag formats for MP3 files, nor is there a standard container format that would support metadata and obviate the need for tags.
Question: What would be needed to support metadata and obviate the need for tags?

Output: a standard container format

QUES: In Europe the Wayback Machine could be interpreted as violating copyright laws. Only the content creator can decide where their content is published or duplicated, so the Archive would have to delete pages from its system upon request of the creator. The exclusion policies for the Wayback Machine may be found in the FAQ section of the site. The Wayback Machine also retroactively respects robots.txt files, i.e., pages that currently are blocked to robots on the live web temporarily will be made unavailable from the archives as well.

What would the Internet Archive have to do if requested by someone whose content is available on Wayback Machine?
What is the answer?
ANS: delete pages from its system

QUES: During the 1960s the Department of Defense continued to scrutinize the reserve forces and to question the number of divisions and brigades as well as the redundancy of maintaining two reserve components, the Army National Guard and the Army Reserve. In 1967 Secretary of Defense Robert McNamara decided that 15 combat divisions in the Army National Guard were unnecessary and cut the number to 8 divisions (1 mechanized infantry, 2 armored, and 5 infantry), but increased the number of brigades from 7 to 18 (1 airborne, 1 armored, 2 mechanized infantry, and 14 infantry). The loss of the divisions did not set well with the states. Their objections included the inadequate maneuver element mix for those that remained and the end to the practice of rotating divisional commands among the states that supported them. Under the proposal, the remaining division commanders were to reside in the state of the division base. No reduction, however, in total Army National Guard strength was to take place, which convinced the governors to accept the plan. The states reorganized their forces accordingly between 1 December 1967 and 1 May 1968.
How many division did the Secretary of Defense cut the original 10 down to?

ANS: unanswerable

Lossy audio compression is used in a wide range of applications. In addition to the direct applications (mp3 players or computers), digitally compressed audio streams are used in most video DVDs, digital television, streaming media on the internet, satellite and cable radio, and increasingly in terrestrial radio broadcasts. Lossy compression typically achieves far greater compression than lossless compression (data of 5 percent to 20 percent of the original stream, rather than 50 percent to 60 percent), by discarding less-critical data.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How are higher percentages of cable radio attained with Lossy?
Ah, so.. unanswerable

Question: Birds need to alter their metabolism in order to meet the demands of migration. The storage of energy through the accumulation of fat and the control of sleep in nocturnal migrants require special physiological adaptations. In addition, the feathers of a bird suffer from wear-and-tear and require to be molted. The timing of this molt - usually once a year but sometimes twice - varies with some species molting prior to moving to their winter grounds and others molting prior to returning to their breeding grounds. Apart from physiological adaptations, migration sometimes requires behavioural changes such as flying in flocks to reduce the energy used in migration or the risk of predation.
Try to answer this question if possible: Why do birds need to molt?
Answer: feathers of a bird suffer from wear-and-tear

Question: The city's population increased more than sixfold during the first half of the 20th century, fed largely by an influx of European, Middle Eastern (Lebanese, Assyrian/Chaldean), and Southern migrants to work in the burgeoning automobile industry. In 1940, Whites were 90.4% of the city's population. Since 1950 the city has seen a major shift in its population to the suburbs. In 1910, fewer than 6,000 blacks called the city home; in 1930 more than 120,000 blacks lived in Detroit. The thousands of African Americans who came to Detroit were part of the Great Migration of the 20th century.
Try to answer this question if possible: What was the movement of blacks to northern cities called?
Answer:
Great Migration
