Question

which type of scientific statement is defined as \a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable\?

○ hypothesis
○ theory
○ law
○ probability

Explanation:

To solve this, we analyze each option:

• A hypothesis is a possible explanation for a scientific question, based on prior knowledge/research, and is testable.
• A theory is a well - substantiated explanation of some aspect of the natural world, based on a body of facts. It is not just a possible explanation but a more established one.
• A scientific law describes a phenomenon in nature, often in a mathematical form, and it states what happens, not a possible explanation.
• Probability is a measure of the likelihood of an event, not a type of scientific statement that explains a scientific question.

So the correct option is the one with "hypothesis".

Answer:

A. hypothesis
