What is an explanation for a question or problem that can be tested?

Answer 1

A hypothesis.

A theory is an explanation for why and how something works, and a good theory can predict (hence) what will happen in a new situation based on the theory or idea. A hypothesis is a prediction based on a theory or idea.

Are you looking for the term #"falsifiability"#?

A theory or hypothesis can be falsified, which is the process of looking for evidence to support the theory's falsity. If a theory cannot be falsified, meaning there is no possible (conceivable!) confounding evidence, then the theory is unscientific and only an interesting conjecture. Currently, theories and hypotheses can only be shown to be consistent with existing evidence and experiments.

We might look to the theory of evolution as an example of a falsifiable theory. What evidence would we expect if the theory of evolution were incorrect? One professor of biology famously suggested #"rabbits in the Precambrian"#, i.e. the presence of placental mammals millions of year before they were believed to evolve.

In order to demonstrate that the conventional wisdom, or orthodoxy, is insufficient, scientists therefore search for experiments that refute theories and hypotheses. Using the example of evolution, young earth creationists have occasionally proposed that God, or his evil twin, created the Earth with the appearance of age, complete with fossil dinosaurs. If this is true, they have certainly fooled us, as such a hypothesis is not falsifiable and a deceitful creator is capable of anything.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
