Consider the following statements about the Channel Tunnel (Chunnel): 1. It connects the United Kingdom to France under the English Channel. 2. It was opened in 1994. 3. The Eurostar train service uses the Channel Tunnel. 4. It is the world's longest underwater tunnel. Which of the above statements is/are CORRECT?

Explanation

All four statements are correct. NASA's Jet Propulsion Laboratory describes the Channel Tunnel as a 50.5 km rail tunnel beneath the English Channel near the Strait of Dover, connecting England with northern France. Its two ends connect with Folkestone and Coquelles. The tunnel officially opened in 1994, and Eurostar passenger services use it. Statement 4 does not claim that the tunnel is the longest in every category; it refers specifically to the part beneath the sea. This 37.9 km undersea section is considered the world's longest.

Why the other options are wrong

• (A) A omits statement 3, but Eurostar passenger services use the Channel Tunnel. Statement 3 is therefore also correct, making A incomplete.
• (B) B omits statement 4, but the section beneath the sea is considered the world's longest. Statement 4 is therefore also correct, making B incomplete.
• (D) D omits statement 1, but the tunnel runs beneath the English Channel and links the United Kingdom with France. Statement 1 is therefore also correct, so D is not the correct combination.

Concept

This tests transport geography, especially strategic links between countries and major engineering projects. RAS asks about tunnels, straits, canals, and rail links because their locations, opening years, uses, and distinctive records show how physical geography connects with economic and geopolitical activity.
