Explanation:

• Seismograph: It is a device that records ground - motion during an earthquake. So, the feature “showed that earthquakes are not signs of heavens anger but natural events” matches with it.
• Water Clock: It is a timekeeping device that measures time without relying on sunlight. So, “helped measure time accurately without sunlight” is its feature.
• Paper: Before paper, heavy materials like stone (clay tablets in some cultures) or shells (in some ancient writing systems) were used for writing. Paper replaced these heavy writing surfaces. Also, paper allowed for the printing of Buddhist prayers (as in ancient Chinese Buddhist scriptures printed on paper). So, “helped replace heavy writing surfaces such as stone or shells” and “allowed for the printing of Buddhist prayers” match with paper.
• Sundial: A sundial is a device that measures time with the aid of the sun. So, “helped measure time with the aid of the sun” is its feature.
• Perpetual Calendar: A perpetual calendar is designed to track days, weeks, and months across a year (in the context of the Chinese perpetual calendar which was a sophisticated calendar system that could account for the solar year of approximately 365.5 days). So, “helped track days, weeks and months across a year made up of 365.5 days” matches with it.

Answer:

• Seismograph: showed that earthquakes are not signs of heavens anger but natural events
• Water Clock: helped measure time accurately without sunlight
• Paper: helped replace heavy writing surfaces such as stone or shells; allowed for the printing of Buddhist prayers
• Sundial: helped measure time with the aid of the sun
• Perpetual Calendar: helped track days, weeks and months across a year made up of 365.5 days
