Problem: The strongest element of style noted by critics and reviewers is Lee's talent for narration, which in an early review in Time was called "tactile brilliance". Writing a decade later, another scholar noted, "Harper Lee has a remarkable gift of story-telling. Her art is visual, and with cinematographic fluidity and subtlety we see a scene melting into another scene without jolts of transition." Lee combines the narrator's voice of a child observing her surroundings with a grown woman's reflecting on her childhood, using the ambiguity of this voice combined with the narrative technique of flashback to play intricately with perspectives. This narrative method allows Lee to tell a "delightfully deceptive" story that mixes the simplicity of childhood observation with adult situations complicated by hidden motivations and unquestioned tradition. However, at times the blending causes reviewers to question Scout's preternatural vocabulary and depth of understanding. Both Harding LeMay and the novelist and literary critic Granville Hicks expressed doubt that children as sheltered as Scout and Jem could understand the complexities and horrors involved in the trial for Tom Robinson's life.
What narrative technique does Lee use to combine the adult's perspective with the child's observations??

Answer: flashback


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Insects were the earliest organisms to produce and sense sounds. Insects make sounds mostly by mechanical action of appendages. In grasshoppers and crickets, this is achieved by stridulation. Cicadas make the loudest sounds among the insects by producing and amplifying sounds with special modifications to their body and musculature. The African cicada Brevisana brevis has been measured at 106.7 decibels at a distance of 50 cm (20 in). Some insects, such as the Helicoverpa zeamoths, hawk moths and Hedylid butterflies, can hear ultrasound and take evasive action when they sense that they have been detected by bats. Some moths produce ultrasonic clicks that were once thought to have a role in jamming bat echolocation. The ultrasonic clicks were subsequently found to be produced mostly by unpalatable moths to warn bats, just as warning colorations are used against predators that hunt by sight. Some otherwise palatable moths have evolved to mimic these calls. More recently, the claim that some moths can jam bat sonar has been revisited. Ultrasonic recording and high-speed infrared videography of bat-moth interactions suggest the palatable tiger moth really does defend against attacking big brown bats using ultrasonic clicks that jam bat sonar.
Insects can sense what?
A: sounds


Context and question: In the days following the disaster, an international reconnaissance team of engineers was dispatched to the region to make a detailed preliminary survey of damaged buildings. Their findings show a variety of reasons why many constructions failed to withstand the earthquake.
What did the team of engineers do?
Answer: make a detailed preliminary survey of damaged buildings


Question: The written score, however, does not usually contain explicit instructions as to how to interpret the piece in terms of production or performance, apart from directions for dynamics, tempo and expression (to a certain extent). This is left to the discretion of the performers, who are guided by their personal experience and musical education, their knowledge of the work's idiom, their personal artistic tastes, and the accumulated body of historic performance practices.
Is there an answer to this question: What does the written score not usually contain explicitly? 

Answer: instructions


Question: The majority of simplified characters are drawn from conventional abbreviated forms, or ancient standard forms. For example, the orthodox character 來 lái ("come") was written with the structure 来 in the clerical script (隶书 / 隸書, lìshū) of the Han dynasty. This clerical form uses one fewer stroke, and was thus adopted as a simplified form. The character 雲 yún ("cloud") was written with the structure 云 in the oracle bone script of the Shang dynasty, and had remained in use later as a phonetic loan in the meaning of "to say" while the 雨 radical was added to differentiate meanings. The simplified form adopts the original structure.
Is there an answer to this question: What was written with the structure in the clerical script?

Answer:
orthodox character
