A friend asked me to answer this question: What is the last name of the person who contributed to albums and hit singles as a songwriter?, using the article: Steven Lee Lukather (born October 21, 1957) is an American guitarist, singer, songwriter, arranger and record producer, best known as a founding member of Toto. A prolific session musician, Lukather has recorded guitar tracks for more than 1,500 albums representing a broad array of artists and genres. He has also contributed to albums and hit singles as a songwriter, arranger and producer. Lukather was a prominent contributor to several studio albums by Michael Jackson, including Thriller, the best-selling album of all time. Lukather has released seven solo albums, the latest of which, Transition, was released in January 2013. In 1976, when Lukather was nineteen years old, he was invited by his high school friends David Paich and the Porcaro brothers Steve and Jeff to join them in forming their band, Toto. He has been a member of the band ever since it began, and is still fully contributing to their album composition and touring. Lukather's reputation as a guitarist and his association with Paich and the Porcaro brothers, who also became established artists, allowed him to secure a steady flow of session work in the 1970s and 1980s. Lukather has been nominated for twelve Grammy Awards, and has won five. While his work with Toto was predominantly based on pop rock music and his solo work ventures into progressive rock and hard rock, many of Lukather's side-projects are focused on jazz fusion. He held a long-time collaboration with jazz guitarist Larry Carlton that produced a Grammy-winning live album, and he was a member of the jazz fusion band Los Lobotomys, a collaboration of notable session musicians. Since 2012, Lukather has toured with former Beatles drummer Ringo Starr's live supergroup, the All-Starr Band. Influenced by such blues-rock guitarists as Jimi Hendrix and Jimmy Page, and such jazz fusion players as Al Di Meola and Frank Gambale, Lukather is known for a "melodic and intense" playing style. He is also recognized for his efficiency in the studio, often recording tracks in one take using minimal..., what would be the answer ?

A friend asked me to answer this question: What is the name of the city that celebrated its rebirth at the Panama-Pacific International Exposition in 1915?, using the article: Rebuilding was rapid and performed on a grand scale. Rejecting calls to completely remake the street grid, San Franciscans opted for speed. Amadeo Giannini's Bank of Italy, later to become Bank of America, provided loans for many of those whose livelihoods had been devastated. The influential San Francisco Planning and Urban Research Association or SPUR was founded in 1910 to address the quality of housing after the earthquake. The earthquake hastened development of western neighborhoods that survived the fire, including Pacific Heights, where many of the city's wealthy rebuilt their homes. In turn, the destroyed mansions of Nob Hill became grand hotels. City Hall rose again in splendid Beaux Arts style, and the city celebrated its rebirth at the Panama-Pacific International Exposition in 1915.It was during this period San Francisco built some of its most important infrastructure. Civil Engineer Michael O'Shaughnessy was hired by San Francisco Mayor James Rolph as chief engineer for the city in September 1912 to supervise the construction of the Twin Peaks Reservoir, the Stockton Street Tunnel, the Twin Peaks Tunnel, the San Francisco Municipal Railway, the Auxiliary Water Supply System, and new sewers. San Francisco's streetcar system, of which the J, K, L, M, and N lines survive today, was pushed to completion by O'Shaughnessy between 1915 and 1927. It was the O'Shaughnessy Dam, Hetch Hetchy Reservoir, and Hetch Hetchy Aqueduct that would have the largest effect on San Francisco. An abundant water supply enabled San Francisco to develop into the city it has become today. In ensuing years, the city solidified its standing as a financial capital; in the wake of the 1929 stock market crash, not a single San Francisco-based bank failed. Indeed, it was at the height of the Great Depression that San Francisco undertook two great civil engineering projects, simultaneously constructing the San FranciscoOakland Bay Bridge and the Golden Gate Bridge, completing them in 1936 and 1937, respectively. It was in this..., what would be the answer ?

A friend asked me to answer this question: It is helpful if what tool can be broken down?, using the article: The ice must be cut through, broken up, or melted. Tools can be directly pushed into snow and firn (snow that is compressed, but not yet turned to ice, which typically happens at a depth of 60 metres (200 ft) to 120 metres (390 ft)); this method is not effective in ice, but it is perfectly adequate for obtaining samples from the uppermost layers. For ice, two options are percussion drilling and rotary drilling. Percussion drilling uses a sharp tool such as a chisel, which strikes the ice to fracture and fragment it. More common are rotary cutting tools, which have a rotating blade or set of blades at the bottom of the borehole to cut away the ice. For small tools the rotation can be provided by hand, using a T-handle or a carpenter's brace. Some tools can also be set up to make use of ordinary household power drills, or they may include a motor to drive the rotation. If the torque is supplied from the surface, then the entire drill string must be rigid so that it can be rotated; but it is also possible to place a motor just above the bottom of the drill string, and have it supply power directly to the drill bit.If the ice is to be melted instead of cut, then heat must be generated. An electrical heater built into the drill string can heat the ice directly, or it can heat the material it is embedded in, which in turn heats the ice. Heat can also be sent down the drill string; hot water or steam pumped down from the surface can be used to heat a metal drillhead, or the water or steam can be allowed to emerge from the drillhead and melt the ice directly. In at least one case a drilling project experimented with heating the drillhead on the surface, and then lowering it into the hole.Many ice drilling locations are very difficult to access, and drills must be designed so that they can be transported to the drill site. The equipment should be as light and portable as possible. It is helpful if the equipment can be broken down so that the individual components can be carried separately, thus reducing..., what would be the answer ?
