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:

• Hypothesis: A hypothesis is a possible explanation for a scientific question, based on prior knowledge/research, and is testable (through experiments).
• Theory: 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.
• Law: A scientific law describes a phenomenon in nature, often in a mathematical form, and does not provide an explanation but rather a description of what happens.
• Probability: It is a measure of the likelihood of an event occurring and is not a type of scientific statement that explains a scientific question.

So, the correct option is the one that matches the definition of a hypothesis.

Answer:

A. hypothesis
