Hi Orson, here is my “crack” at your question. Remember, there are many correct answers to these questions. The goal with the “what/why/how” is not always to get a right “answer”, but to engage critically with the text at hand.
What: Advances in the history of clock-making.
Why: The ability to keep time in an emerging technological society was becoming increasingly important.
How: By listing examples of technological advances in clock making – escapement, coiled spring/fusee, pendulum. These advances improved timekeeping, although the pendulum had issues of its own (inefficiency).
