A hypothesis must be Responses [Choice A] accurate [Choice B] mathematical [Choice C] short [Choice D] testable

[Choice D] testable

A hypothesis must be [Choice D] testable.

The correct answer is [Choice D] testable. A hypothesis is a proposed explanation or prediction that can be tested through experimentation or observation. It should be possible to gather data and evidence to support or refute the hypothesis.

To determine the answer to this multiple-choice question, we need to understand the definition of a hypothesis and evaluate the given options. A hypothesis must meet certain criteria, such as being testable, in order to be considered valid.

To answer this question correctly, we can go through each option and eliminate the ones that do not accurately describe what a hypothesis should be:

- [Choice A] accurate: While accuracy is important, a hypothesis does not necessarily have to be accurate before being tested. It is more about being able to gather evidence to support or reject the hypothesis.

- [Choice B] mathematical: A hypothesis does not necessarily have to involve mathematics. Hypotheses can be formulated in various disciplines and fields, not just in the realm of mathematics.

- [Choice C] short: The length of a hypothesis is not a determining factor in its validity or testability. A hypothesis can be short or long, as long as it is clear and specific enough to be tested.

Therefore, the only option that accurately describes the necessary characteristic of a hypothesis is [Choice D] testable.
