Problem: Given the question: Extract the answer to the question from the following context. Question: How do Atticus and Alexandra differ? Context: 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".

Q: Extract the answer to the question from the following context. Question: Which came first, computer plotters, inkjet printers or laser printers? Context: Stepper motors were and still are often used in computer printers, optical scanners, and digital photocopiers to move the optical scanning element, the print head carriage (of dot matrix and inkjet printers), and the platen or feed rollers. Likewise, many computer plotters (which since the early 1990s have been replaced with large-format inkjet and laser printers) used rotary stepper motors for pen and platen movement; the typical alternatives here were either linear stepper motors or servomotors with closed-loop analog control systems.
