206 | When the book was released, reviewers noted that it was divided into two parts, and opinion was mixed about Lee's ability to connect them. The first part of the novel concerns the children's fascination with Boo Radley and their feelings of safety and comfort in the neighborhood. Reviewers were generally charmed by Scout and Jem's observations of their quirky neighbors. One writer was so impressed by Lee's detailed explanations of the people of Maycomb that he categorized the book as Southern romantic regionalism. This sentimentalism can be seen in Lee's representation of the Southern caste system to explain almost every character's behavior in the novel. Scout's Aunt Alexandra attributes Maycomb's inhabitants' faults and advantages to genealogy (families that have gambling streaks and drinking streaks), and the narrator sets the action and characters amid a finely detailed background of the Finch family history and the history of Maycomb. This regionalist theme is further reflected in Mayella Ewell's apparent powerlessness to admit her advances toward Tom Robinson, and Scout's definition of "fine folks" being people with good sense who do the best they can with what they have. The South itself, with its traditions and taboos, seems to drive the plot more than the characters. | Besides the children's fascination with Boo, the first part of the book was concerned about their feelings for what? | 56d196b2e7d4791d00902067 | 263 | the neighborhood |

210 | Tom Robinson is the chief example among several innocents destroyed carelessly or deliberately throughout the novel. However, scholar Christopher Metress connects the mockingbird to Boo Radley: "Instead of wanting to exploit Boo for her own fun (as she does in the beginning of the novel by putting on gothic plays about his history), Scout comes to see him as a 'mockingbird'—that is, as someone with an inner goodness that must be cherished." The last pages of the book illustrate this as Scout relates the moral of a story Atticus has been reading to her, and in allusions to both Boo Radley and Tom Robinson states about a character who was misunderstood, "when they finally saw him, why he hadn't done any of those things ... Atticus, he was real nice," to which he responds, "Most people are, Scout, when you finally see them." | Who is the main example of an innocent destroyed in the novel? | 56d261f359d6e41400145f36 | 0 | Tom Robinson |

213 | The novel exposes the loss of innocence so frequently that reviewer R. A. Dave claims that because every character has to face, or even suffer defeat, the book takes on elements of a classical tragedy. In exploring how each character deals with his or her own personal defeat, Lee builds a framework to judge whether the characters are heroes or fools. She guides the reader in such judgments, alternating between unabashed adoration and biting irony. Scout's experience with the Missionary Society is an ironic juxtaposition of women who mock her, gossip, and "reflect a smug, colonialist attitude toward other races" while giving the "appearance of gentility, piety, and morality". Conversely, when Atticus loses Tom's case, he is last to leave the courtroom, except for his children and the black spectators in the colored balcony, who rise silently as he walks underneath them, to honor his efforts. | Reviewer R. A. Dave classified the novel how? | 56d2639159d6e41400145f48 | 183 | classical tragedy |
214 | Initial reactions to the novel were varied. The New Yorker declared it "skilled, unpretentious, and totally ingenious", and The Atlantic Monthly's reviewer rated it as "pleasant, undemanding reading", but found the narrative voice—"a six-year-old girl with the prose style of a well-educated adult"—to be implausible. Time magazine's 1960 review of the book states that it "teaches the reader an astonishing number of useful truths about little girls and about Southern life" and calls Scout Finch "the most appealing child since Carson McCullers' Frankie got left behind at the wedding". The Chicago Sunday Tribune noted the even-handed approach to the narration of the novel's events, writing: "This is in no way a sociological novel. It underlines no cause ... To Kill a Mockingbird is a novel of strong contemporary national significance." | What newspaper wrote that the novel has strong contemporary national significance? | 56d3949f59d6e414001467b8 | 589 | The Chicago Sunday Tribune |
215 | Not all reviewers were enthusiastic. Some lamented the use of poor white Southerners, and one-dimensional black victims, and Granville Hicks labeled the book "melodramatic and contrived". When the book was first released, Southern writer Flannery O'Connor commented, "I think for a child's book it does all right. It's interesting that all the folks that are buying it don't know they're reading a child's book. Somebody ought to say what it is." Carson McCullers apparently agreed with the Time magazine review, writing to a cousin: "Well, honey, one thing we know is that she's been poaching on my literary preserves." | Which reviewer called the book melodramatic and contrived? | 56d3958659d6e414001467c5 | 125 | Granville Hicks |

217 | The 50th anniversary of the novel's release was met with celebrations and reflections on its impact. Eric Zorn of the Chicago Tribune praises Lee's "rich use of language" but writes that the central lesson is that "courage isn't always flashy, isn't always enough, but is always in style". Jane Sullivan in the Sydney Morning Herald agrees, stating that the book "still rouses fresh and horrified indignation" as it examines morality, a topic that has recently become unfashionable. Chimamanda Ngozi Adichie writing in The Guardian states that Lee, rare among American novelists, writes with "a fiercely progressive ink, in which there is nothing inevitable about racism and its very foundation is open to question", comparing her to William Faulkner, who wrote about racism as an inevitability. Literary critic Rosemary Goring in Scotland's The Herald notes the connections between Lee and Jane Austen, stating the book's central theme, that "one’s moral convictions are worth fighting for, even at the risk of being reviled" is eloquently discussed. | Chimamanda Ngozi Adichie vompared Lee to whom? | 56d3977059d6e414001467d5 | 734 | William Faulkner |

219 | Native Alabamian Allen Barra sharply criticized Lee and the novel in The Wall Street Journal calling Atticus a "repository of cracker-barrel epigrams" and the novel represents a "sugar-coated myth" of Alabama history. Barra writes, "It's time to stop pretending that To Kill a Mockingbird is some kind of timeless classic that ranks with the great works of American literature. Its bloodless liberal humanism is sadly dated". Thomas Mallon in The New Yorker criticizes Atticus' stiff and self-righteous demeanor, and calls Scout "a kind of highly constructed doll" whose speech and actions are improbable. Although acknowledging that the novel works, Mallon blasts Lee's "wildly unstable" narrative voice for developing a story about a content neighborhood until it begins to impart morals in the courtroom drama, following with his observation that "the book has begun to cherish its own goodness" by the time the case is over.[note 2] Defending the book, Akin Ajayi writes that justice "is often complicated, but must always be founded upon the notion of equality and fairness for all." Ajayi states that the book forces readers to question issues about race, class, and society, but that it was not written to resolve them. | Who criticized Lee in The Wall Street Journal? | 56d3988759d6e414001467e1 | 17 | Allen Barra |

221 | Furthermore, despite the novel's thematic focus on racial injustice, its black characters are not fully examined. In its use of racial epithets, stereotyped depictions of superstitious blacks, and Calpurnia, who to some critics is an updated version of the "contented slave" motif and to others simply unexplored, the book is viewed as marginalizing black characters. One writer asserts that the use of Scout's narration serves as a convenient mechanism for readers to be innocent and detached from the racial conflict. Scout's voice "functions as the not-me which allows the rest of us—black and white, male and female—to find our relative position in society". A teaching guide for the novel published by The English Journal cautions, "what seems wonderful or powerful to one group of students may seem degrading to another". A Canadian language arts consultant found that the novel resonated well with white students, but that black students found it "demoralizing". Another criticism, articulated by Michael Lind, is that the novel indulges in classist stereotyping and demonization of poor rural "white trash". | Which character has some critics deemed a variation of a contented slave? | 56d3d0c42ccc5a1400d82eac | 197 | Calpurnia |

224 | Diane McWhorter, Pulitzer Prize-winning historian of the Birmingham civil rights campaign, asserts that To Kill a Mockingbird condemns racism instead of racists, and states that every child in the South has moments of racial cognitive dissonance when they are faced with the harsh reality of inequality. This feeling causes them to question the beliefs with which they have been raised, which for many children is what the novel does. McWhorter writes of Lee, "for a white person from the South to write a book like this in the late 1950s is really unusual—by its very existence an act of protest."[note 4] Author James McBride calls Lee brilliant but stops short of calling her brave: "I think by calling Harper Lee brave you kind of absolve yourself of your own racism ... She certainly set the standards in terms of how these issues need to be discussed, but in many ways I feel ... the moral bar's been lowered. And that's really distressing. We need a thousand Atticus Finches." McBride, however, defends the book's sentimentality, and the way Lee approaches the story with "honesty and integrity". | According to Diane McWhorter, every child in the South had to face what? | 56d3e0852ccc5a1400d82f0f | 271 | the harsh reality of inequality |

226 | According to a National Geographic article, the novel is so revered in Monroeville that people quote lines from it like Scripture; yet Harper Lee herself refused to attend any performances, because "she abhors anything that trades on the book's fame". To underscore this sentiment, Lee demanded that a book of recipes named Calpurnia's Cookbook not be published and sold out of the Monroe County Heritage Museum. David Lister in The Independent states that Lee's refusal to speak to reporters made them desire to interview her all the more, and her silence "makes Bob Dylan look like a media tart". Despite her discouragement, a rising number of tourists made to Monroeville a destination, hoping to see Lee's inspiration for the book, or Lee herself. Local residents call them "Mockingbird groupies", and although Lee was not reclusive, she refused publicity and interviews with an emphatic "Hell, no!" | How do the citizens of Monroeville quote lines of the book? | 56d3f1872ccc5a1400d82f75 | 115 | like Scripture |

11 | Solar radiation is absorbed by the Earth's land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived. | The Earth's oceans cover what percentage of the globe? | 56ce5a8faab44d1400b886e2 | 84 | 71 |

When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived. | What is the average temperature of the Earth's surface in Celsius? | 56ce5a8faab44d1400b886e3 | 623 | 14 |

77 | Deciduous trees and plants have been promoted as a means of controlling solar heating and cooling. When planted on the southern side of a building in the northern hemisphere or the northern side in the southern hemisphere, their leaves provide shade during the summer, while the bare limbs allow light to pass during the winter. Since bare, leafless trees shade 1/3 to 1/2 of incident solar radiation, there is a balance between the benefits of summer shading and the corresponding loss of winter heating. In climates with significant heating loads, deciduous trees should not be planted on the Equator facing side of a building because they will interfere with winter solar availability. They can, however, be used on the east and west sides to provide a degree of summer shading without appreciably affecting winter solar gain. | The placement of deciduous trees on the Equator facing side of a building can have a negative effect on solar availability in which season? | 56ce60e4aab44d1400b88715 | 321 | winter |
