Question

multiple choice 1 point
which statement is an inference rather than an observation?
the liquid is bubbling
the solution turned blue
the experiment failed because of contamination
the temperature is 25℃

Explanation:

An observation is a direct - noticed fact. "The liquid is bubbling", "The solution turned blue", and "The temperature is 25°C" are direct observations. "The experiment failed because of contamination" is an inference as it is a conclusion drawn from evidence and reasoning, not a direct - seen fact.

Answer:

The experiment failed because of contamination
