Reading Comprehension — Passage Structure

Most passages follow one of a few blueprints. Recognize the blueprint and you can predict where every answer lives.

~6 min read•Difficulty 3/5

A passage is not a random pile of sentences — it is built. Recognizing the blueprint lets you predict where the main idea, the evidence, and the turn will appear.

The common blueprints

Structure	Shape	Watch for
Problem → Solution	names a trouble, then a fix	problem, challenge, however, one answer
Claim → Evidence	states a view, then backs it	because, for example, studies show
Compare → Contrast	weighs two things	whereas, unlike, similarly, on the other hand
Chronological	events in time order	first, then, by 1990, eventually
General → Specific	broad opener, narrowing detail	topic sentence, then particulars

Signposts are your map

Transition words tell you what the next sentence does:

Adds: moreover, furthermore, in addition
Turns: however, yet, but, on the contrary
Concludes: therefore, thus, as a result
Illustrates: for example, for instance, such as

When you hit a turn word like however, slow down: the author is about to change direction, and questions love that pivot.

Where the answer hides

Main idea $\to$ first or last sentence, or right after a "however" turn.
The author's real point in a contrast $\to$ the side introduced by the turn word, not the side dismissed before it.
Support for a claim $\to$ the sentence beginning "because" or "for example".

Mapping structure in one quick pass means you re-read almost nothing.

Worked examples

Example 1 (difficulty 3/5)

Read this passage: "For years, coastal towns fought erosion by building concrete sea walls. The walls held briefly, but they starved nearby beaches of sand and often collapsed in big storms. A newer approach restores dunes and marshes, letting natural barriers absorb the waves — and, so far, it is proving both cheaper and more durable." The passage is organized mainly as:

◎ Predict the answer first:

Tips

Underline every transition word on your first read — they sketch the structure for free.
In a contrast passage, the author usually favors the side that comes after the turn word.
If you can state the blueprint in five words, you have understood the passage well enough to answer fast.

Common mistakes

Treating a contrast passage as "two equal sides"

Why: Both sides get described, so they look balanced.

Fix: Find the turn word; the author almost always leans toward one side and signals it.

Missing the pivot at "however / yet / but"

Why: Readers skim transitions as filler.

Fix: Treat turn words as flashing lights — the main point often lives right after them.
