Problem: A friend asked me to answer this question: Whose mother is wounded by a bomb blast?, using the article: Peter, an engineer, has recurring nightmares in which he and everyone he knows suffer through violent, alien invasion-like confrontations with an unknown enemy. He reluctantly visits a clinic to receive psychiatric help, only to find a patient there who reveals that he is having the same visions, prompting Peter to believe his visions are of an upcoming invasion. That night, invading spaceships open fire on the city, causing significant damage. Peter and his wife, Alice, barricade their apartment amid the sounds of slaughter from ground troops. A soldier dressed in armor breaks through the barricade and finds Lucy, one of Peter and Alice's children, hiding under a table. The soldier pauses to examine the girl, and that distraction allows Peter and Alice to immobilize the soldier. Peter, now armed with the soldier's weapon, leads his family out of the building. Based on his visions, Peter and his family agree to seek shelter at the factory where Peter works. He is able to bypass the rifle's biometric authentication and kill soldiers guarding the apartment building's exit. They make their way to a tunnel entrance to safely travel to the factory, but not before Alice is injured from a bomb blast. As they regroup, the soldier from their apartment appears, having tracked them with a homing signal on the rifle Peter took. To Peter's shock, the soldier removes his helmet and appears human. Peter forces the soldier to carry Alice to the factory. There, his boss, David, explains that the invasion has been expected for many years. A medic examines Alice but informs Peter that he cannot save her. As David's men drag the invading soldier off to execute him, he yells to Peter that he can save Alice. Peter agrees to stay with the soldier to save Alice; David will evacuate their children to a subway station where a transport train awaits to take them all to an offsite base., what would be the answer ?

A: Lucy

Problem: A friend asked me to answer this question: What has difficulty preventing rotation in firn and at boundaries between layers of different densities?, using the article: The two main requirements of an anti-torque system are that it should prevent rotation of the sonde, and it should allow easy movement of the drill up and down the borehole. Attempts have been made to design drills with counter-rotating components so that overall torque is minimized, but these have had limited success. Five kinds of anti-torque systems have been devised for use with cable-suspended EM drills, though not all are in current use, and some drills have used a combination of more than one design. The first drill to require an anti-torque system was used at Camp Century by CRREL in 1966; the drill incorporated a set of hinged friction blades that swung out from the sonde when the drill motor was started. These were found to have very weak friction against the borehole wall, and were ineffective; the drill had to be controlled carefully to prevent twisting the cable. No other drills have attempted to use this approach.For the next deployment of the drill leaf springs were installed, and this has proved to be a more durable design. These are mounted vertically, with a curve outwards so that they are easily compressed by the borehole wall, and can slide up and down with the movement of the drill. They pass easily through any areas of irregularity in the borehole, but the edges of the springs cut into the borehole wall and prevent rotation. Leaf springs are very simple mechanically, with the additional benefit of being easy to adjust by changing the spacing between the end points. They can be placed anywhere on the drill that does not rotate, so they do not add length to the sonde. The shape is usually a fourth-order parabola, since this has been determined to provide the most even loading against the borehole wall. Leaf springs have been found to be so effective that they can prevent rotation even in heavy drills running at full power.Skate antitorque systems have blades attached to vertical bars which are pushed against the borehole wall; the blades dig into the wall and provide the..., what would be the answer ?

A: Skates

Problem: A friend asked me to answer this question: What was the last name of Etty's admirer?, using the article: By the time Etty exhibited Musidora, the theme was becoming something of a cliche, such that by 1850 it was described by The Literary Gazette as "a favourite subject for a dip of the brush". As interest in studies of Musidora waned, its role as a pretext for nude paintings by English artists was replaced by Lady Godiva, who had become a topic of increased interest owing to Alfred, Lord Tennyson's poem Godiva. After the death of William Wordsworth in 1850, James Thomson ceased to be a major influence on writers. From the 1870s his popularity with readers waned, and by the end of the 20th century his works other than Rule, Britannia! were little known.When Etty died in 1849, despite having worked and exhibited until his death, he was still regarded by many as a pornographer. Charles Robert Leslie observed shortly after Etty's death that "[Etty] himself, thinking and meaning no evil, was not aware of the manner in which his works were regarded by grosser minds". Interest in him declined as new movements came to characterise painting in Britain, and by the end of the 19th century the value of his paintings had fallen. It is likely that the composition and style of John Everett Millais's controversial The Knight Errant was influenced by Musidora, but other than Millais, and Etty's admirer and imitator William Edward Frost, few other artists were directly influenced by Etty's work. In 1882 Vanity Fair commented on Musidora that "I know only too well how the rough and his female companion behave in front of pictures such as Etty's bather. I have seen the gangs of workmen strolling round, and I know that their artistic interest in studies of the nude is emphatically embarrassing." By the early 20th century Victorian styles of art and literature fell dramatically out of fashion in Britain, and by 1915 the word "Victorian" had become a derogatory term. Frederick Mentone's The Human Form in Art (1944) was one of the few 20th-century academic works to favourably view Musidora., what would be the answer ?

A:
Frost
