LSAT Practice Test

When an author states that something is or is not the case, they are making assertions of truth. This means that they are presenting a statement as being true or false based on their perspective or evidence they provide. This type of conclusion is based on the author's beliefs or information they have gathered.

Option A is incorrect as there is no mention of two types of conclusions in the question stem. Option C does not relate to the question about an author stating something is or is not the case. Option D is not relevant to the question about the type of conclusion made by an author stating something is or is not the case.
