Final answer:
Ancient boats and modern spaceships share similarities in their propulsion systems, navigation systems, and construction and engineering.
Step-by-step explanation:
Ancient boats and modern spaceships share some similarities. Both rely on propulsion systems to move through their respective environments. For example, ancient boats used oars or sails to harness the power of wind or human effort to move across bodies of water. Similarly, modern spaceships use rockets or ion propulsion systems to propel themselves through the vacuum of space.
Additionally, both ancient boats and modern spaceships require navigation systems to determine their location and direction. Ancient sailors used celestial navigation and landmarks to guide their journeys, while modern spaceships use GPS and onboard computer systems to navigate in space.
Lastly, both ancient boats and modern spaceships require careful construction and engineering. Ancient boats were built to withstand the forces of wind and water, while modern spaceships are designed to withstand the harsh conditions of space, such as extreme temperatures and radiation.
