Context and question: Incestuous matings by the purple-crowned fairy wren Malurus coronatus result in severe fitness costs due to inbreeding depression (greater than 30% reduction in hatchability of eggs). Females paired with related males may undertake extra pair matings (see Promiscuity#Other animals for 90% frequency in avian species) that can reduce the negative effects of inbreeding. However, there are ecological and demographic constraints on extra pair matings. Nevertheless, 43% of broods produced by incestuously paired females contained extra pair young.
What can reduce the negative effects of inbreeding?
Answer: Females paired with related males may undertake extra pair matings
Context and question: In a 1964 interview, Lee remarked that her aspiration was "to be ... the Jane Austen of South Alabama." Both Austen and Lee challenged the social status quo and valued individual worth over social standing. When Scout embarrasses her poorer classmate, Walter Cunningham, at the Finch home one day, Calpurnia, their black cook, chastises and punishes her for doing so. Atticus respects Calpurnia's judgment, and later in the book even stands up to his sister, the formidable Aunt Alexandra, when she strongly suggests they fire Calpurnia. One writer notes that Scout, "in Austenian fashion", satirizes women with whom she does not wish to identify. Literary critic Jean Blackall lists the priorities shared by the two authors: "affirmation of order in society, obedience, courtesy, and respect for the individual without regard for status".
Who is Atticus Finch's sibling?
Answer: Aunt Alexandra
Context and question: All Greeks were united, however, in their determination to liberate the Greek-speaking provinces of the Ottoman Empire, regardless of the dialect they spoke. Especially in Crete, a prolonged revolt in 18661869 had raised nationalist fervour. When war broke out between Russia and the Ottomans in 1877, Greek popular sentiment rallied to Russia's side, but Greece was too poor, and too concerned of British intervention, to officially enter the war. Nevertheless, in 1881, Thessaly and small parts of Epirus were ceded to Greece as part of the Treaty of Berlin, while frustrating Greek hopes of receiving Crete.
In what year did the Treaty of Berlin occur?
Answer:
1881
