Identify key elements of an argument and explain their function

Introduction: Deconstructing the Argument

Welcome! In this chapter, we are going to learn how to be "Argument Detectives." When we read a passage in Thinking Skills Paper 2, we aren't just reading for the "gist" or the story. Instead, we are looking for the structure.

Think of an argument like a building. The Main Conclusion is the roof—the final thing being supported. The Reasons are the pillars holding it up. Sometimes there are Intermediate Conclusions that act like a second floor, and Examples that act like decorations to show you what the architect means. Understanding these "key elements" is the first step toward masterly critical thinking.

The Six Key Elements

According to your syllabus, there are six specific elements you must be able to identify and explain. Let's look at them one by one.

1. Main Conclusion (MC)

The Main Conclusion is the most important part of the argument. It is the final claim that the author wants you to accept after you have read everything else.

How to spot it:
• Look for indicator words like therefore, thus, hence, consequently, or so.
• Ask yourself: "What is the author trying to get me to believe or do?"
• Use the "Therefore Test": Try putting the word "therefore" in front of a sentence. If it makes the most sense as the final result of the whole passage, it's likely the MC.

2. Intermediate Conclusion (IC)

An Intermediate Conclusion is a bit of a "double agent." It is a conclusion because it is supported by reasons, but it also acts as a reason itself because it helps support the Main Conclusion.

Analogy: Imagine a staircase. The ground floor is your Reason. The landing halfway up is the Intermediate Conclusion. The top floor is the Main Conclusion. You need the landing to reach the top!

Function: To provide a "stepping stone" in the reasoning, making the link between basic reasons and the final conclusion stronger.

3. Reason (R)

Reasons are the foundational claims that provide support for a conclusion. In your exam, any evidence (like statistics or facts) is treated as a reason because we cannot verify the evidence ourselves during the test.

Function: To provide the "proof" or justification for a conclusion. Without reasons, you don't have an argument—you just have an opinion!

4. Counter-assertion (CA)

A Counter-assertion is a claim that supports the opposite side of the author's argument. It is usually just a single statement without any supporting evidence provided by the author.

How to spot it: Look for "pivot" words like however, although, critics claim, or on the other hand.

Function: Authors use these to acknowledge that another viewpoint exists before they move on to prove why their own view is better.

5. Counter-argument (C-arg)

A Counter-argument is more complex than a counter-assertion. It is a full "mini-argument" for the opposing side, containing both a reason and a conclusion that goes against the author's Main Conclusion.

Function: To present a challenge to the author’s position. The author usually includes this so they can then "rebut" (defeat) it, which makes their own argument look even stronger.

6. Example (Ex)

An Example is a specific instance used to illustrate or support a reason. It turns a general idea into a concrete "real-world" case.

Example: "We should ban sugary drinks (Reason) because they cause health problems. For instance, high sugar intake is linked to Type \( 2 \) diabetes (Example)."

Function: To clarify a reason or make a general claim more persuasive by showing it is true in a specific case.

Note: For help with things the author hasn't explicitly stated, see the chapter on "Identify unstated assumptions in an argument."

Explaining the Function

In Paper 2, you won't just be asked to label these parts; you will be asked to explain their function. This means explaining how that piece fits into the "machine" of the argument.

Use this "Formula" for your answers:
1. Identify the element: "The phrase '...' is an Intermediate Conclusion."
2. Explain what supports it: "It is supported by the reasons in paragraph \( 1 \)."
3. Explain what it supports: "It then acts as a reason to support the Main Conclusion that..."

Quick Review: The Roles of Elements

• Reasons support Conclusions.
• Intermediate Conclusions are supported by Reasons and support the Main Conclusion.
• Counter-elements (CA and C-arg) show the opposing view.
• Examples illustrate or give "weight" to a Reason.

Common Mistakes to Avoid

Don't worry if this seems tricky at first! Many students make these common errors:

• Confusing IC and MC: Always look for the "bigger" picture. The MC is the ultimate point; the IC is just a helper.
• Confusing CA and C-arg: Remember, an "assertion" is just a statement. An "argument" needs at least one reason and a conclusion.
• Treating Examples as Reasons: An example is a specific case; a reason is a general principle or a broader claim. In the exam, look at whether the text is talking about one specific person/event (Example) or a general rule (Reason).

Step-by-Step: How to Analyze a Passage

1. Scan for Indicator Words: Circle words like so, because, however, for instance.
2. Find the "Goal": Identify the Main Conclusion first. Everything else should point toward it.
3. Map the Connections: Ask, "Does sentence A lead to sentence B?" If yes, sentence A is a reason and B is a conclusion.
4. Identify the "Enemy": Look for any sentences that disagree with the author's goal. These are your Counter-assertions or Counter-arguments.

Key Takeaways

• Main Conclusion: The final destination of the argument.
• Intermediate Conclusion: A mid-way point that acts as both conclusion and reason.
• Reason: The basic support for any conclusion.
• Counter-assertion/Argument: The "other side" of the debate.
• Example: A specific case used to illustrate a point.
