Problem: LaserDisc:

During the early years, MCA also manufactured discs for other companies including Paramount, Disney and Warner Bros. Some of them added their own names to the disc jacket to signify that the movie was not owned by MCA. After Discovision Associates shut down in early 1982, Universal Studio's videodisc software label, called MCA Videodisc until 1984, began reissuing many DiscoVision titles. Unfortunately, quite a few, such as Battlestar Galactica and Jaws, were time-compressed versions of their CAV or CLV Disco Vision originals. The time-compressed CLV re-issue of Jaws no longer had the original soundtrack, having had incidental background music replaced for the video disc version due to licensing cost (the music would not be available until the THX LaserDisc box set was released in 1995). One Universal/Columbia co-production issued by MCA Disco Vision in both CAV and CLV versions, The Electric Horseman, is still not available in any other home video format with its original score intact; even the most recent DVD release has had substantial music replacements of both instrumental score and Willie Nelson's songs. An MCA release of Universal's Howard the Duck, sees only the start credits shown in widescreen before changing to 4:3 for the rest of the film. For many years this was the only disc-based release of the film, until widescreen DVD formats were released with extras. Also, the LaserDisc release of E.T. the Extra-Terrestrial is the only format to include the cut scene of Harrison Ford playing the part of the school headmaster telling off Elliott for letting the frogs free in the biology class.

What other companies did MCA manufacture discs for?

Problem: Compact disc:

Replicated CDs are mass-produced initially using a hydraulic press. Small granules of heated raw polycarbonate plastic are fed into the press. A screw forces the liquefied plastic into the mold cavity. The mold closes with a metal stamper in contact with the disc surface. The plastic is allowed to cool and harden. Once opened, the disc substrate is removed from the mold by a robotic arm, and a 15 mm diameter center hole (called a stacking ring) is created. The time it takes to "stamp" one CD is usually two to three seconds.

How large is the screw that forces the plastic into the cavity?

A: unanswerable

Problem: Multiracial American:

By the 1980s, parents of mixed-race children (and adults of mixed-race ancestry) began to organize and lobby for the ability to show more than one ethnic category on Census and other legal forms. They refused to be put into just one category. When the U.S. government proposed the addition of the category of "bi-racial" or "multiracial" in 1988, the response from the general public was mostly negative. Some African-American organizations and political leaders, such as Senator Diane Watson and Representative Augustus Hawkins, were particularly vocal in their rejection of the category. They feared a loss in political and economic power if African Americans abandoned their one category.

Who lobbied for the ability to show more than one ethnic category on legal forms before the 1980s?

A: unanswerable

Problem: Dog:

The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.

What do humans get exposed to with pets that may help them not get sick?

A:
immune-stimulating microorganisms
