Also, is it possible to have more than one conclusion in any argument like multiple premises?
This is a very interesting question. The answer is, yes and no.
If it's an argument, then it has a single conclusion. There is one, main point that the author is making.
However, the evidence and premises supporting that conclusion can take many forms--statistical data, opinion, or sometimes, other arguments
. And those arguments, offered in support of the authors primary conclusion, will in turn have their own sub-conclusions, sub-premises, and (sometimes) sub-assumptions.
For example, consider the following flawed logic: "Owning giraffes is illegal. All giraffes are yellow with spots, and your pet fluffy is yellow with spots, so it's clearly a giraffe. You're breaking the law." The conclusion in this case is that you are breaking the law, based on the premise that you own a giraffe which is illegal. However, the reason that I think you own a giraffe is an argument itself. Since the secondary argument is based on a classic flaw of formal logic, the support for my main conclusion is undermined, and in all likelihood you are not breaking the anti-giraffe laws.
You'll see these from time to time on regular Critical Reasoning prompts, but not terribly often. However, this type of structure shows up all the time on bold statement
question. A typical answer choice to the question "which of the following describes the role of the boldface sentence in the author's argument" might go, "the first is the author's main conclusion and the second is a subsidiary conclusion supporting the main conclusion." Your job would be to figure out if that was an accurate summation.
