Polo is unique in requiring all players to hold their mallet in their right hand. This rule exists for safety - left-handed and right-handed players approaching from opposite directions would be at risk of collision. All other major sports allow left-handed play.

New York City's nickname 'The Big Apple' originated in the 1920s when sportswriter John J. Fitz Gerald used it to describe the city's horse racing tracks. It was later popularized in a 1970s tourism campaign and has been the city's official nickname since.

The first ODI was played between England and Australia at Melbourne on January 5, 1971. Geoffrey Boycott faced the first ball of the match, which was bowled by Jeff Thomson. This match was originally arranged as a Test replacement after the scheduled Test was abandoned due to rain.

This riddle describes a ship: 'weight in my belly' refers to cargo, 'trees on my back' means it's made of wood (traditional ships), 'nails in my ribs' refers to the wooden planks fastened with nails, and 'feet do I lack' because ships float without feet.

In a volcano, the 'thunder' (rumbling) precedes the 'lightning' (volcanic lightning), and the 'rain' (lava) is hot and dries/burns the land.

Smoke is the 'child' of fire (white/bright father), rises like a bird without wings, causes eyes to water (tears), and dissipates into the air.

At Earth's exact center, gravity becomes zero because you're equally surrounded by mass in all directions. The gravitational pull from all sides cancels out completely. Gravity increases slightly as you go down from surface to the mantle, then decreases toward zero at the center.

Stars appear to twinkle (scintillation) because Earth's atmosphere has varying temperature and density layers that refract starlight differently as it passes through. This causes the light to bend and flicker. The option calls this 'pollution' but means atmospheric disturbance - the explanation is correct even if the wording is imprecise.

In a perfectly insulated closed room, a fan increases temperature. The fan's motor converts electrical energy to heat, and the air friction from the fan blades also generates thermal energy. While fans cool people by evaporation, they add net heat to a closed system.

The Sun produces energy through nuclear fusion, where hydrogen nuclei combine to form helium. This process converts mass to energy according to E=mc², releasing enormous heat and light. Fission is incorrect (that's splitting atoms), and the helium-to-hydrogen direction is backwards.
