Since it was quite easy to stack interconnections (wires) inside the embedding matrix, the approach allowed designers to forget completely about the routing of wires (usually a time-consuming operation of PCB design): Anywhere the designer needs a connection, the machine will draw a wire in straight line from one location/pin to another. This led to very short design times (no complex algorithms to use even for high density designs) as well as reduced crosstalk (which is worse when wires run parallel to each otherwhich almost never happens in Multiwire), though the cost is too high to compete with cheaper PCB technologies when large quantities are needed.
It was difficult to stack interconnections inside of what?
A: unanswerable

Based on the strength of his work, Universal signed Spielberg to do four TV films. The first was a Richard Matheson adaptation called Duel. The film is about a psychotic Peterbilt 281 tanker truck driver who chases the terrified driver (Dennis Weaver) of a small Plymouth Valiant and tries to run him off the road. Special praise of this film by the influential British critic Dilys Powell was highly significant to Spielberg's career. Another TV film (Something Evil) was made and released to capitalize on the popularity of The Exorcist, then a major best-selling book which had not yet been released as a film. He fulfilled his contract by directing the TV film-length pilot of a show called Savage, starring Martin Landau. Spielberg's debut full-length feature film was The Sugarland Express, about a married couple who are chased by police as the couple tries to regain custody of their baby. Spielberg's cinematography for the police chase was praised by reviewers, and The Hollywood Reporter stated that "a major new director is on the horizon.":223 However, the film fared poorly at the box office and received a limited release.
Which TV film Spielberg directed played off 'The Exorcist'?
A: Something Evil

Other microscopic procedures may also aid in identifying infectious agents. Almost all cells readily stain with a number of basic dyes due to the electrostatic attraction between negatively charged cellular molecules and the positive charge on the dye. A cell is normally transparent under a microscope, and using a stain increases the contrast of a cell with its background. Staining a cell with a dye such as Giemsa stain or crystal violet allows a microscopist to describe its size, shape, internal and external components and its associations with other cells. The response of bacteria to different staining procedures is used in the taxonomic classification of microbes as well. Two methods, the Gram stain and the acid-fast stain, are the standard approaches used to classify bacteria and to diagnosis of disease. The Gram stain identifies the bacterial groups Firmicutes and Actinobacteria, both of which contain many significant human pathogens. The acid-fast staining procedure identifies the Actinobacterial genera Mycobacterium and Nocardia.
What is Geimsa stain?
A:
a dye
