What is a simple way to make a scientific question specific?

Correct answer: Clearly state the object and factor to be measured

The direct answer is option A: clearly state the object and the factor to be measured. A specific scientific question tells us what is being studied and which variable or factor will be observed or measured. It should be clear enough that someone can plan a fair investigation and know what data to collect. For example, asking how the amount of light affects the height of a plant is more specific than asking whether light is good. Option A is correct because it identifies the subject and the measurable factor. Option B is wrong because difficult words can make a question confusing without making it precise. Option C is wrong because placing the answer in the question removes the need for investigation and introduces bias. Option D is wrong because removing evidence makes the question impossible or weaker to test. Memory cue: a strong scientific question names “what” and “which factor,” and avoids vague words such as “better” unless they are defined.
