Final answer:
The correct response is 'laconically', as it describes someone who communicates in a brief and succinct manner, much like Quincey Morris is characterized. It aligns with the idea of clarity and purpose in communication, avoiding superfluous language.
Step-by-step explanation:
To speak laconically means to say something in a concise and terse manner, often using few words, but still conveying the message effectively. The term originates from Laconia, a region of Greece, where the Spartans were known for their brevity of speech. In contrast to this, hypnotically suggests speaking in a manner that captivates or mesmerizes the listener, often through rhythmic and repetitious language, while phonographically involves recording and reproducing sound, which is unrelated to the manner of speaking. Lastly, scripturally implies speaking based on or according to religious scriptures. Given the options, the correct answer to the question, 'One who speaks like Quincey Morris, with the briefest amount of words to get to a point is speaking ________', is laconically.
The passage provided, with its mention of clear diction and avoidance of commonplace and mean expressions, also alludes to the idea of speaking effectively and with purpose. The preference for clarity over using overly elaborate or rare words ties back to the concept of laconic speech. This kind of communication aims to be direct and to the point while eschewing unnecessary verbosity, which aligns with the ideal of speaking in a manner that is 'clear without being mean', as described in the provided text.
