Question

question 1 - 2
scientists study many different types of questions, from how cells function to how galaxies form. because their investigations vary, they often rely on different tools and methods suited to their field of study. however, the goal of using these methods remains the same in science. why is it important for scientists to use different methods across different fields?
methods should always be identical.
each field has unique questions and phenomena that require specific techniques.
methods are unimportant if the conclusion is correct.
science works best when only one method is used.

Explanation:

In science, different fields have unique questions and phenomena. For example, in biology (studying cells) and astronomy (studying galaxies), the nature of what is being investigated is distinct. Biology might use microscopes and cell - culture techniques to study cell function, while astronomy uses telescopes and spectroscopy to study galaxy formation. Each of these unique questions and phenomena in their respective fields requires specific techniques that are tailored to accurately observe, measure, and analyze the subject matter.

Option 1 “Methods should always be identical” is incorrect because as shown by different scientific fields (like the biology - astronomy example), identical methods would not be effective for different types of questions (e.g., a microscope is useless for studying galaxies). Option 3 “Methods are unimportant if the conclusion is correct” is wrong because the scientific method is about reliable and repeatable ways of getting to a conclusion. If methods are not appropriate (even if by chance a conclusion seems correct), the result may not be valid (e.g., using a wrong statistical method in an experiment might give a false positive conclusion). Option 4 “Science works best when only one method is used” is false since different methods can provide complementary evidence (e.g., in medicine, both clinical trials (experimental method) and observational studies (non - experimental method) are used to understand the effectiveness of a drug).

Answer:

B. Each field has unique questions and phenomena that require specific techniques
