Final answer:
The statement about looking both ways at a crossing and staying clear of train tracks is true for safety reasons, including the risks posed by atmospheric pressure changes causing suction near fast-moving trains.
Step-by-step explanation:
The statement, 'You should look both ways when approaching the crossing and always stay clear of the tracks when a train is approaching', is True. It is essential to ensure personal safety near train tracks. Trains move quickly and cannot stop abruptly, hence it is crucial to remain vigilant and cautious near crossings to prevent accidents. Atmospheric pressure changes caused by fast-moving trains can create suction forces strong enough to pull a person standing too close to the tracks towards the train. This phenomenon increases the risk of injury or worse, making it imperative to stand at a safe distance when a train is passing.
