A more thorough explanation:

Definition: To refute an assertion or prove an allegation false.

Example 1: The scientist was able to disprove the theory that the earth was flat by providing evidence of its round shape.

Example 2: The defense attorney tried to disprove the prosecution's claim that the defendant was at the scene of the crime by presenting an alibi witness.

These examples illustrate how someone can disprove a statement or claim by providing evidence that contradicts it. In the first example, the scientist was able to disprove the theory that the earth was flat by presenting evidence of its round shape. In the second example, the defense attorney was able to disprove the prosecution's claim that the defendant was at the scene of the crime by presenting an alibi witness. In both cases, the original assertion was proven false by evidence that contradicted it.
