1. a hypothesis must be testable and meaning it can be proved to be incorrect .
2. what is the data that is collected that can either agree or disagree with a prediction?

1. Falsifiable

2. Evidence

Explanation:

Falsifiable means it can be incorrect. A scientific hypothesis is only deemed scientific if tests can be done to also disprove the idea. If a hypothesis will stand despite refuting arguments, with the help of evidence, then it will be more acceptable by the scientific community.

Evidence is obtained through observation, research, and testing through experimentation. In the scientific method, it is evidence that helps a researcher or scientist conclude whether the hypothesis is true or false. Evidence can either support a hypothesis or disprove a hypothesis.

You can take Alfred Wegener's theory on continental drift. Although his idea is well-supported nowadays, when he first proposed it, it was rejected because he could not explain the mechanism in which the continents moved. Lacking evidence to show this, the scientific community could not accept his hypothesis.
