Which of the following is the best scientific question for proposing a hypothesis and designing an experiment on the effect of a drug (drug x) on decreasing blood pressure? a. should we lower blood pressure? b. how does drug x affect blood pressure readings? c. does drug x affect blood pressure? d. why is drug x important to blood pressure?

The correct answer is B. How does Drug X affect blood pressure readings?

Explanation:

A scientific question is a question that guides scientific research or process due to this, this question should be appropriate. This implies the question should be specific or address the phenomenon studied; it should be testable, which means it can be answered through experiments; and it should provide meaningful information, due to this, it is not recommended to use yes/no questions.

According to this, the most appropriate question in this case is "How does Drug X affect blood pressure readings?" because this question is the only one that really focuses on the phenomenon proposed (effect of drug x on blood pressure), and besides this it is an open question rather than a yes/no question which means it provides meaningful information and can be tested. On the other hand," Does Drug X affect blood pressure?" can be answered only with a yes or no and it is not appropriate, and others such as "Should we lower blood pressure?" or "Why is Drug X important to blood pressure?" do not address the phenomenon.
