Explanation:

• "The 2026 Winter Olympics are the first time the Olympic Games will use artificial snow." → False (Previous Winter Olympics have used artificial snow).
• "Artificial snow is safer and more predictable for athletes." → True (Consistent conditions help athletes).
• "Artificial snow can be used only when there’s no natural snow on the ground." → False (Can be used to supplement natural snow).
• "Snow machines can use millions of gallons of water making snow for the Olympics." → True (Large - scale snow - making requires significant water).
• "The air outside must be colder than water’s freezing point for artificial snow to stay frozen." → True (To prevent melting, the temperature needs to be below \(0^\circ\text{C}\)).

Answer:

B. Artificial snow is safer and more predictable for athletes.
D. Snow machines can use millions of gallons of water making snow for the Olympics.
E. The air outside must be colder than water’s freezing point for artificial snow to stay frozen.
