How to Read

Today, we are going to learn how to read. So hopefully you are familiar with your ABCs.

We already know we should spend about 4 to 4:45 minutes per passage. But in those 4 minutes, you cannot read an RC passage the way you would read a textbook. You need to read it for its reasoning structure rather than trying to understand every fact.


Reading a Textbook vs. Reading a RC Passage

When you read a textbook, say a physics textbook, you are actually trying to understand the material. Every equation, every term, every assumption — you need to absorb it so you can reproduce it on an exam. You cannot read an RC passage this way. The topic is frankly irrelevant.

What matters is the reasoning structure. Every RC passage is essentially a large LR-style argument. A typical LR question is 2 to 4 lines. An RC passage is 15 to 17 lines. But it is still one big argument. For every line, ask yourself: why did the author write this?

The author will write any given sentence for one of three reasons:

  • They are making a point
  • They are supporting, elaborating, explaining, or building up on a point
  • They are providing background information or context

This is similiar to the conclusion, premise, and background information of an LR argument. In a RC passage, there are many such "conclusions".


Example 1: The Silk Road

Read this paragraph first without any commentary:

For much of the twentieth century, historians treated the Silk Road less as a subject of serious inquiry than as a romantic shorthand for premodern globalization. The image of camel caravans threading through Central Asian deserts carrying Chinese silk westward to Rome was vivid enough to anchor popular imagination, but scholars working within area studies were often indifferent to it. Specialists in Chinese history, Persian history, and Byzantine history each claimed segments of the route as their own without much interest in the connective tissue between them. It was not until the 1990s, when historians trained in transregional methods began publishing sustained studies of the networks linking these civilizations, that the Silk Road emerged as a coherent object of historical analysis in its own right.

Now let's read it for reasoning structure, sentence by sentence.

"For much of the twentieth century, historians treated the Silk Road less as a subject of serious inquiry than as a romantic shorthand for premodern globalization."

Why did the author write this? The author is making a point: the Silk Road was not taken seriously as a topic of historical study.

"The image of camel caravans... but scholars working within area studies were often indifferent to it. Specialists in Chinese history, Persian history, and Byzantine history each claimed segments of the route as their own without much interest in the connective tissue between them."

Why did the author write this? To elaborate on the point above. These two lines further try to explain why the Silk Road was not taken seriously.

"It was not until the 1990s, when historians trained in transregional methods began publishing sustained studies... that the Silk Road emerged as a coherent object of historical analysis in its own right."

Why did the author write this? This is the next point. While historians ignored the Silk Road for most of the twentieth century, the 1990s marked a turning point where it became a legitimate area of study.


Example 2: The Adiabatic Process

When a gas is compressed rapidly, there is insufficient time for heat to transfer to the surrounding environment. As a result, the temperature of the gas rises during compression. This relationship is described by the adiabatic process, governed by the equation PV^γ = constant, where γ represents the ratio of specific heats. Engineers designing internal combustion engines rely on this principle to predict pressure and temperature changes across the compression stroke.

"When a gas is compressed rapidly, there is insufficient time for heat to transfer to the surrounding environment."

Why did the author write this? The author seems to be making a point about what happens when gas is compressed rapidly. We do not care why or how. We just accept what the author is saying.

"As a result, the temperature of the gas rises during compression."

Why did the author write this? This is actually the point the author was building toward. The temperature rises during compression. The previous sentence was not the point — it was the support for this one. Notice how our thinking has to adapt as we read further. What looked like the point a moment ago was actually the support.

"This relationship is described by the adiabatic process, governed by the equation PV^γ = constant, where γ represents the ratio of specific heats."

Why did the author write this? No new point here. This is background information and context for the point made above. Do not worry about the equation. It plays no role in the reasoning structure.

"Engineers designing internal combustion engines rely on this principle to predict pressure and temperature changes across the compression stroke."

Why did the author write this? A new point: engineers apply this principle when designing engines.


Annotating as You Read

Obviously, we cannot explicitly ask "why did the author write this?" for every sentence in a RC passage — we simply do not have the time. Instead, we accomplish this through highlighting.

Here is the format I recommend:

Yellow/Cyan — any point the author makes. If two points appear side by side, use yellow for one and cyan for the other.

Pink/Green — any support, explanation, elaboration for those points. If multiple distinct pieces of support are given, alternate between pink and green.

Background information — no highlighting. read and move on.

As you read each paragraph, pause and highlight what you have identified. Here are the two examples from above with the highlighting applied. In choosing to highlight/not highlight, and choosing the colour, you are essentially identifying the reasoning structure. In choosing yellow, you are saying, "here is a point". In choosing pink, you are saying, "we are supporting this point".

Silk Road paragraph:

For much of the twentieth century, historians treated the Silk Road less as a subject of serious inquiry than as a romantic shorthand for premodern globalization. The image of camel caravans threading through Central Asian deserts carrying Chinese silk westward to Rome was vivid enough to anchor popular imagination, but scholars working within area studies were often indifferent to it. Specialists in Chinese history, Persian history, and Byzantine history each claimed segments of the route as their own without much interest in the connective tissue between them. It was not until the 1990s, when historians trained in transregional methods began publishing sustained studies of the networks linking these civilizations, that the Silk Road emerged as a coherent object of historical analysis in its own right.

Adiabatic process paragraph:

When a gas is compressed rapidly, there is insufficient time for heat to transfer to the surrounding environment. As a result, the temperature of the gas rises during compression. This relationship is described by the adiabatic process, governed by the equation PV^γ = constant, where γ represents the ratio of specific heats. Engineers designing internal combustion engines rely on this principle to predict pressure and temperature changes across the compression stroke.


Do I really need so much highlighting?

No one I talked to highlighted as much as I did on RC passages. People thought I was crazy. Some prep books say highlighting is a waste of time entirely. Others say just mark the main points. And then there is me, possibly the only person on earth who highlighted almost everything.

The honest answer is that you need to find a system that works for you. For me, choosing between colours forced me to do active reading and identify the reasoning structure as I went. If I had to skip a question and come back to it after completing other passages, the highlights were still there to give me a quick read of each point. It also helped while reading: if a later paragraph refuted or elaborated on something from earlier, I could glance back and find the exact sentence it was refuting/elaborating.

Regardless of whether you highlight heavily, lightly, or not at all, reading for reasoning structure is non-negotiable. Try a few approaches, settle on a consistent system, and stick with it. You do not want to be experimenting on test day.


A Full Passage, Annotated

Let's look at the reasoning structure of a full passage. Read the passage below once without any commentary first, then study the annotated version. Just observe for now — there are plenty of practice passages waiting for you at the end of this chapter.

Passage:

For much of the twentieth century, historians treated the Silk Road less as a subject of serious inquiry than as a romantic shorthand for premodern globalization. The image of camel caravans threading through Central Asian deserts carrying Chinese silk westward to Rome was vivid enough to anchor popular imagination, but scholars working within area studies were often indifferent to it. Specialists in Chinese history, Persian history, and Byzantine history each claimed segments of the route as their own without much interest in the connective tissue between them. It was not until the 1990s, when historians trained in transregional methods began publishing sustained studies of the networks linking these civilizations, that the Silk Road emerged as a coherent object of historical analysis in its own right.

The dominant interpretation that followed this turn was emphatically cultural. Scholars such as Valerie Hansen argued that the goods exchanged along the route were rarely the luxury commodities of popular legend; surviving contract documents and waste paper from oasis towns like Dunhuang suggest instead that local trade in ordinary goods predominated. What made the Silk Road historically significant, on this view, was not the volume of commerce but the movement of ideas, religious practices, and artistic conventions across enormous distances. Buddhism's transmission from South Asia through Central Asia to China, the westward diffusion of paper-making technology, and the spread of Manichaean and Nestorian Christian communities all figured as evidence that the route functioned primarily as a corridor for cultural exchange rather than a mechanism of economic integration.

This cultural interpretation has not gone unchallenged. Economic historians have countered that the surviving documentary record overrepresents local oasis economies and underrepresents the long-distance luxury trade that left fewer written traces. They point to the consistent appearance of Roman glassware in Chinese tombs and Chinese silk in Roman-era burial sites as evidence of sustained, deliberate exchange over vast distances. Further, they argue that cultural transmission rarely occurs in the absence of a prior commercial relationship; the merchants who carried goods were the same individuals who carried scripts, pathogens, and religious missionaries. Separating commerce from culture, on this view, imposes a distinction that ancient and medieval actors themselves would not have recognized.

The most persuasive recent accounts have moved away from this binary altogether. Rather than asking whether the Silk Road was primarily economic or primarily cultural, historians now tend to treat it as an infrastructure of connectivity whose significance varied by period, by commodity, and by the political conditions that prevailed along its length. The route contracted when empires fragmented and expanded when powerful states like the Tang dynasty or the Mongol Khanates imposed order over large stretches of territory. Understanding the Silk Road, these historians suggest, requires abandoning the idea of a single road with a single function in favor of an adaptive network whose character was always the product of contingent historical forces.

This cultural interpretation has not gone unchallengedWhy did the author write this?Oh, so the above view has been challenged by other views. Economic historians have countered that the surviving documentary record overrepresents local oasis economies and underrepresents the long-distance luxury trade that left fewer written tracesWhy did the author write this?a competing view: economic historians push back against the cultural interpretation. They point to the consistent appearance of Roman glassware in Chinese tombs and Chinese silk in Roman-era burial sites as evidence of sustained, deliberate exchange over vast distancesWhy did the author write this?archaeological evidence used to argue for the importance of long-distance commercial exchange. Further, they argue that cultural transmission rarely occurs in the absence of a prior commercial relationship; the merchants who carried goods were the same individuals who carried scripts, pathogens, and religious missionariesWhy did the author write this?the economic historians go further: cultural and commercial cannot be separated, which weakens the cultural interpretation on its own terms.

The most persuasive recent accounts have moved away from this binary altogetherWhy did the author write this?So there is a view that is better than both the economic and cultural one. Rather than asking whether the Silk Road was primarily economic or primarily cultural, historians now tend to treat it as an infrastructure of connectivity whose significance varied by period, by commodity, and by the political conditions that prevailed along its lengthWhy did the author write this?a new synthesis: the best accounts reject the economic vs. cultural binary and treat the Silk Road as a flexible network. The route contracted when empires fragmented and expanded when powerful states like the Tang dynasty or the Mongol Khanates imposed order over large stretches of territoryWhy did the author write this?context establishing the political conditions that shaped the network's reach. Understanding the Silk Road, these historians suggest, requires abandoning the idea of a single road with a single function in favor of an adaptive network whose character was always the product of contingent historical forcesWhy did the author write this?the conclusion: the Silk Road must be understood as adaptive and historically contingent, not fixed.


The Power of Highlighting Points

Here is how highlighting can come in clutch sometimes. Consider this line from paragraph 4:

"The most persuasive recent accounts have moved away from this binary altogether."

If you encounter this line and wonder what binary it is referring to, a quick glance at your highlighted points from paragraphs 2 and 3 tells you immediately: the cultural interpretation and the economic interpretation. You do not have to reread two full paragraphs.

Smart people will point out that if you have been actively reading and understanding the reasoning structure as you go, you should already know what the two viewpoints are. They are obviously correct. But that does not mean highlighting is useless. Active reading and good highlighting are not mutually exclusive. Highlighting reinforces your understanding as you read, and it gives you a safety net when you are three passages deep, slightly fatigued, and need to locate a specific point quickly without rereading everything above it. The value of highlighting is not that it replaces understanding. It is that it makes your understanding accessible at a glance when time is tight.

At the end of the day, make a system that works for you and stick with it. The only wrong answer is having no system at all.


TL;DR

  1. Spend the first 4 to 4:45 minutes of each passage reading it for its reasoning structure.
  2. Reading for reasoning structure means asking "why did the author write this" after every sentence.
  3. Have a consistent system for capturing that reasoning structure, whether that means heavy highlighting, minimal highlighting, or none at all.

The practice drill for this chapter has a few passages to read for reasoning structure. No answering questions yet — just practice reading and highlighting on the interface. The interface is the same as the real test, so get comfortable using it.
