Including Kerry, the Democratic primary race had 10 candidates, including attorney Paul J. Sheehy, State Representative Anthony R. DiFruscia, John J. Desmond and Robert B. Kennedy. Kerry ran a "very expensive, sophisticated campaign", financed by out-of-state backers and supported by many young volunteers. DiFruscia's campaign headquarters shared the same building as Kerry's. On the eve of the September 19 primary, police found Kerry's younger brother Cameron and campaign field director Thomas J. Vallely, breaking into where the building's telephone lines were located. They were arrested and charged with "breaking and entering with the intent to commit grand larceny", but the charges were dropped a year later. At the time of the incident, DiFruscia alleged that the two were trying to disrupt his get-out-the vote efforts. Vallely and Cameron Kerry maintained that they were only checking their own telephone lines because they had received an anonymous call warning that the Kerry lines would be cut.
Who did Kerry share a campaign headquarters with?
A: Anthony R. DiFruscia

Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.
Single-layer printed circuit boards have trace layers where?
A: unanswerable

Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
What is the only planet in the solar system found by empirical observation?
A: unanswerable

Baptists have faced many controversies in their 400-year history, controversies of the level of crises. Baptist historian Walter Shurden says the word "crisis" comes from the Greek word meaning "to decide." Shurden writes that contrary to the presumed negative view of crises, some controversies that reach a crisis level may actually be "positive and highly productive." He claims that even schism, though never ideal, has often produced positive results. In his opinion crises among Baptists each have become decision-moments that shaped their future. Some controversies that have shaped Baptists include the "missions crisis", the "slavery crisis", the "landmark crisis", and the "modernist crisis".
What has never helped shape Baptists?
A:
unanswerable
