Laerdal Tunnel in Norway (Laerdal-Aurland) is the world's longest road tunnel at 24.5 kilometers. The Mont Blanc Tunnel connects France and Italy but is much shorter. Arlberg Tunnel in Austria and Zhongnanshan Tunnel in China are significant road tunnels but not the longest. Norway has several of the world's longest road tunnels due to its mountainous terrain.

Correct answer is (3).

Correct Answer: Dead Sea

The Rogun Dam (Rogunsky) in Tajikistan is the world's highest dam at 335 meters. Tehri Dam is India's tallest at 260.5 meters, Vajont Dam is in Italy, and Inguri Dam is in Georgia - all shorter than Rogun.

Eurasia is the largest continental landmass on Earth, covering about 36% of the planet's total land area (approximately 55 million square kilometers). Australia is the smallest continent, Greenland is the world's largest island, and the Gulf of Mexico is a body of water.

Correct answer is (1).

The Atlantic Ocean was historically called the "Hearing Pond" in maritime navigation contexts because ships would listen for signals and communicate across this vast ocean between continents. The Pacific Ocean, Nile River, and Indian Ocean are not known by this nickname.

Angel Falls in Venezuela is the highest uninterrupted waterfall in the world with a height of 979 meters (3,212 feet). Gavarnie and Stubach are also waterfalls but much shorter. Option D 'Anegl' appears to be a misspelling of Angel.

Gulf Stream (Atlantic) and Kuro Siwo/Kuroshio (Pacific) are warm currents that transport tropical water poleward. British Columbian Current and Benguela Current are both cold currents - the question is poorly framed with two correct answers. Benguela flows northward along southwest Africa, carrying cold water from the Benguela Upwelling System.

The Amazon River has the world's largest drainage basin at about 7.5 million square kilometers - covering 40% of South America and draining parts of 8 countries. By comparison, the Nile has about 3.3 million sq km. Though the Nile is the longest river, the Amazon carries more water and has a vastly larger catchment area.

The Trans-Siberian Railway is the longest railway line in the world, spanning 9,289 km (5,772 miles) across Russia from Moscow to Vladivostok. It crosses multiple time zones and landscapes.

The Earth's core is the hottest part of our planet, with temperatures reaching up to 6000°C in the inner core. This is due to residual heat from Earth's formation and radioactive decay. The surface, ocean surface, and equator are all much cooler in comparison.

The Sargasso Sea (note: spelled 'Sargasso', not 'Saragossa' in the option, but this is clearly referring to it) is the only sea without a coastline. It's defined by ocean currents in the North Atlantic Ocean, bounded by the Gulf Stream, North Atlantic Current, and other currents. All other seas listed (White Sea, Sea of Okhotsk, Tasman Sea) are marginal seas with coastlines.
