Which invention allowed explorers to cross the ocean more easily?

• A. Concrete
• B. Cristallo
• C. Compass
• D. Benin Bronzes

Answer: (C)

Navigating across open water relies on knowing which way you’re headed, even when landmarks disappear or the sky is overcast. The compass provides a reliable sense of direction by pointing toward magnetic north, allowing sailors to set and maintain a course over long distances. This ability to stay on a chosen line across the ocean made true ocean crossings practical and safer, enabling ambitious voyages and the broader reach of explorers. The other items are not about navigation: concrete is a building material, cristallo is a decorative crystal, and Benin Bronzes are artworks, none of which improve sea travel or help determine direction.
