Answer : 1. "12%"
Explanation :

12% of world trade passes through the Suez Canal, which handles the shipping route between Asia and Europe. The canal has faced disruption following recent attacks by Yemen's Iran-aligned Houthi group on ships in the Red Sea. This has blocked trade and prompted the establishment of a naval task force for safe passage. The hostilities affect the movement of global goods, causing supply chain backups and shortages. The attacks are part of the ongoing conflict in Yemen between the Houthis and the Saudi-led coalition. The location of the Suez Canal makes disruptions strategically important.
