Explanation:

In academic writing, one the most important things is to ensure that a thesis, or argument, is objective and valid, and this objectivity and validity is precisely given when the author does not just choose a correct argument that can be verifiable through research, but also shows the possible viewpoints that might arise as a counterpoint to the main argument. This counter argument, counterclaim, thus, is the way in which a writer of an academic essay displays his knowledge and research on a matter, and shows how he understands that his own claim, no matter how correct, can have counterpoints, or arguments against it, that will be the challenge for the writer, as he needs to not just prove his argument, but also disprove the counterclaims.
