[1] In the twelfth century, polymath Al-Jazari pioneered advanced mechanical engineering, documenting his designs in the *Book of Knowledge of Ingenious Mechanical Devices*. [2] His work was not merely theoretical; rather, he prioritized constructing functional machines that automated everyday tasks and entertained the royal court. [3] To demonstrate the sophistication of his water-powered automata, he designed a musical boat containing robotic musicians that floated on a lake. [4] These elaborate creations laid the foundational principles of modern robotics and hydraulics.
The writer wants to revise the underlined portion of sentence 3 (shown below in brackets) to provide the most specific, concrete visual details that illustrate the mechanical complexity and entertainment value of the automaton:
'To demonstrate the sophistication of his water-powered automata, he [designed a musical boat containing robotic musicians that floated on a lake].'
Which choice best accomplishes this goal?
- engineered a floating wooden vessel featuring four automated musicians—including a harpist and two drummers���whose limbs moved via camshafts to play distinct rhythmic patterns.Answer
- Bcreated a decorative vessel that traveled across the royal palace's artificial lake while playing musical tunes to entertain the ruler's guests.
- Cfashioned an aquatic boat with mechanical puppets inside that would perform songs, which was accomplished by using a system of water power.
- Dconstructed an automated boat with mechanical figures playing instruments, they performed complex songs using water pressure.
