based on the scenario, select the statement(s) that accurately identify eves question and hypothesis.

□ eve’s hypothesis is \if i eat walnuts before bed, then i will have fresh breath in the morning.\
□ eve’s question was \why do i have fresh breath?\
□ eve’s hypothesis is \eve woke up and realized that even though she had not brushed her teeth, her breath was already fresh.\
□ eve’s hypothesis was \why do i have fresh breath?\
□ eve’s question was \if i eat walnuts before bed, then i will have fresh breath in the morning.\

Explanation:

• For the hypothesis: A hypothesis is a testable prediction. The statement "If I eat walnuts before bed, then I will have fresh breath in the morning" is a prediction about the relationship between eating walnuts and fresh breath, so it's the hypothesis.
• For the question: The question is what Eve is wondering, which is "Why do I have fresh breath?".
• The other options are incorrect: The statement about waking up with fresh breath is an observation, not a hypothesis. The question cannot be a hypothesis and vice versa, so the options mixing them are wrong.

Answer:

A. Eve's hypothesis is "If I eat walnuts before bed, then I will have fresh breath in the morning."
B. Eve's question was "Why do I have fresh breath?"
