Question 2

A good hypothesis should be testable.

A hypothesis is fundamentally a statement that can be tested through experimentation or observation, making option B the most appropriate choice in this context.

A) Original idea not based on observations

This option is incorrect because a good hypothesis is typically rooted in observations or previous research. An original idea that is not based on any evidence does not provide a solid foundation for testing and may lead to false conclusions.

B) Should be testable

This option is correct as a good hypothesis must be formulated in a way that allows for empirical testing and validation. A testable hypothesis can be supported or refuted through experimentation, making it essential for scientific inquiry.

C) Raises further questions

While a good hypothesis may indeed lead to further questions, this characteristic alone does not define its quality. The primary requirement for a hypothesis is that it can be tested, which is not guaranteed simply by its capacity to provoke additional inquiry.

D) Contains more than two variables

This option is incorrect because a good hypothesis often seeks to isolate variables to determine their relationships. Including more than two variables can complicate the testing process and may lead to ambiguity in results.

Conclusion

In summary, option B is definitively the right answer because a good hypothesis must be testable, allowing it to be evaluated through scientific methods. The other options do not meet the essential criteria for a valid hypothesis, either introducing ambiguity, lack of empirical basis, or unnecessary complexity.
