Which of the following is an example of an observation?

• A. There might be a gas leak as the kitchen smells like LPG.
• B. Gas leaks are dangerous and require caution.
• C. A scientist's hypothesis about gas usage tomorrow.
• D. A prediction about the weather next week.

Answer: (A)

An observation is something you can notice with your senses or instruments in the moment. The statement about the kitchen smelling like LPG describes a smell you can detect right now, which is sensory information about the current situation. It’s describing what is actually perceived, not guessing a cause, making a hypothesis, or predicting the future.

The other statements describe safety judgments, a hypothesis about tomorrow, or a weather forecast, which are not direct observations of the present situation.
