Problem: Newly electrified lines often show a "sparks effect", whereby electrification in passenger rail systems leads to significant jumps in patronage / revenue. The reasons may include electric trains being seen as more modern and attractive to ride, faster and smoother service, and the fact that electrification often goes hand in hand with a general infrastructure and rolling stock overhaul / replacement, which leads to better service quality (in a way that theoretically could also be achieved by doing similar upgrades yet without electrification). Whatever the causes of the sparks effect, it is well established for numerous routes that have electrified over decades.
What can be seen in the newly electrified lines?
The answer is the following: "sparks effect"

Problem: The Diaz administration made political decisions and took legal measures that allowed the elite throughout Mexico to concentrate the nation's wealth by favoring monopolies. During this time, two-fifths of the state's territory was divided among 17 rich families which owned practically all of the arable land in Chihuahua. The state economy grew at a rapid pace during the Porfiriato; the economy in Chihuahua was dominated by agriculture and mining. The Diaz administration helped Governor Luis Terrazas by funding the Municipal Public Library in Chihuahua City and passing a federal initiative for the construction of the railroad from Chihuahua City to Ciudad Juarez. By 1881, the Central Mexican Railroad was completed which connected Mexico City to Ciudad Juarez. In 1883 telephone lines were installed throughout the state, allowing communication between Chihuahua City and Aldama. By 1888 the telephone services were extended from the capital to the cites of Julimes, Meoqui, and Hidalgo del Parral; the telecommunication network in the state covered an estimated 3,500 kilometers. The need of laborers to construct the extensive infrastructure projects resulted in a significant Asian immigration, mostly from China. Asian immigrants soon become integral to the state economy by opening restaurants, small grocery stores, and hotels. By the end of the Terrazas term, the state experienced an increase in commerce, mining, and banking. When the banks were nationalized, Chihuahua became the most important banking state in Mexico.
This state grew at a rapid pace during the Porfiriato.
The answer is the following: Chihuahua

Problem: In 1897, Victoria had written instructions for her funeral, which was to be military as befitting a soldier's daughter and the head of the army, and white instead of black. On 25 January, Edward VII, the Kaiser and Prince Arthur, Duke of Connaught, helped lift her body into the coffin. She was dressed in a white dress and her wedding veil. An array of mementos commemorating her extended family, friends and servants were laid in the coffin with her, at her request, by her doctor and dressers. One of Albert's dressing gowns was placed by her side, with a plaster cast of his hand, while a lock of John Brown's hair, along with a picture of him, was placed in her left hand concealed from the view of the family by a carefully positioned bunch of flowers. Items of jewellery placed on Victoria included the wedding ring of John Brown's mother, given to her by Brown in 1883. Her funeral was held on Saturday, 2 February, in St George's Chapel, Windsor Castle, and after two days of lying-in-state, she was interred beside Prince Albert in Frogmore Mausoleum at Windsor Great Park. As she was laid to rest at the mausoleum, it began to snow.
How was Victoria dressed for burial?
The answer is the following: a white dress and her wedding veil

Problem: A residential elevator is often permitted to be of lower cost and complexity than full commercial elevators. They may have unique design characteristics suited for home furnishings, such as hinged wooden shaft-access doors rather than the typical metal sliding doors of commercial elevators. Construction may be less robust than in commercial designs with shorter maintenance periods, but safety systems such as locks on shaft access doors, fall arrestors, and emergency phones must still be present in the event of malfunction.
What type of doors do commercial elevators use?
The answer is the following:
metal sliding
