How long is a TOEFL academic reading passage in the 2026 format?

ETS publishes the Reading section blueprint — 50 items and 35 raw points across three task types, in a two-stage adaptive design — but does not publish a per-passage word count. The passages on this page are Reach120 practice material, and their lengths are our bank’s, not a statement about the test.

Is this the same as the old TOEFL reading section?

It is the closest surviving relative, and it is not the same. Academic passage reading is now one of three Reading task types rather than the whole section, the section is adaptive, and results are reported on the 1–6 scale used since January 21, 2026. Practice material written for the pre-2026 section still exercises the skill, but it misdescribes the section.

Do I need background knowledge in the subject?

No, and using it is a common way to lose points. Everything required is stated in the passage, and options that are true of the world but not supported by the text are a standard distractor shape.

Why publish the whole passage instead of an excerpt?

Because inference and function questions cannot be practiced on an excerpt — the answer depends on material the excerpt cuts. Every passage here is published whole with its full question set, which is also what makes the answers checkable rather than assertable.

Passage 1

A Butterfly's Long Journey

Life Science · Level 4 · 199 words · 5 questions

Each autumn, millions of monarch butterflies leave the cooling regions where they spent the summer and travel enormous distances to warmer wintering grounds. What makes the feat remarkable is that no single butterfly makes the round trip. [A] The insects that fly south have never seen the destination. [B] Their great-grandparents left it the previous spring. [C] Somehow, the route is passed down without being taught. [D] No parent survives long enough to guide the next flight. How the butterflies find their way is a puzzle scientists are still unraveling. Evidence suggests they use the position of the sun as a kind of compass, adjusting for the time of day so that they keep heading in a steady direction. The wintering sites are strikingly specific. Generation after generation, the butterflies cluster in the same small patches of forest, where the temperature and shelter suit their needs. Crowded together on the trees, they wait out the cold months in a resting state. Because the journey depends on these few sites and on food plants along the route, the migration is fragile. Loss of habitat at either end, or in between, can threaten a spectacle that has unfolded for countless generations.

1. The word "unraveling" in paragraph 2 is closest in meaning to
- A.celebrating
- B.tying together
- C.working outAnswer
- D.ignoring
Why C (working out) is the answer: Scientists are still figuring out the puzzle, so unraveling means working out.
- A. Celebrating is unrelated to solving a puzzle.
- B. Tying together is nearly the opposite of unraveling a puzzle.
- D. They are actively studying it, not ignoring it.
2. What can be inferred from the fact that no single butterfly makes the round trip?
- A.The route cannot be learned by imitating experienced individualsAnswer
- B.Each butterfly lives for several years
- C.The route changes completely each year
- D.The butterflies never reach the wintering grounds
Why A (The route cannot be learned by imitating experienced individuals) is the answer: Since the travelers have never seen the destination, they cannot be copying experienced individuals.
- B. The generations turn over, implying short lives.
- C. They return to the same specific patches each year.
- D. They do reach specific wintering sites.
3. Which sentence best states the main idea of the passage?
- A.Monarchs face no threats to their migration
- B.Monarchs migrate only when older butterflies lead them
- C.Monarch migration is a remarkable, inherited journey that is also fragileAnswer
- D.Monarch wintering sites change randomly each year
Why C (Monarch migration is a remarkable, inherited journey that is also fragile) is the answer: The passage stresses the inherited, remarkable journey and its fragility.
- A. The passage says the migration is fragile and threatened.
- B. No experienced leaders exist for the trip.
- D. They return to the same specific sites.
4. Where would this sentence best fit in paragraph 1? "Several generations are born and die during a single yearly cycle."
- A.Position [C]Answer
- B.Position [B]
- C.Position [A]
- D.Position [D]
Why A (Position [C]) is the answer: The sentence about several generations fits after noting that great-grandparents left the site, explaining how the route is passed down.
- B. Position B interrupts the point that the flyers have never seen the destination.
- C. Position A comes before the generational detail is introduced.
- D. Position D ends the paragraph after the conclusion is drawn, making it redundant.
5. According to paragraph 2, how do the butterflies appear to navigate?
- A.By memorizing landmarks from a previous trip
- B.By using the sun's position, adjusted for the time of dayAnswer
- C.By following the wind
- D.By following older butterflies who know the route
Why B (By using the sun's position, adjusted for the time of day) is the answer: The passage says they use the sun as a compass, adjusting for the time of day.
- A. The migrating insects have never seen the destination.
- C. Wind is not mentioned as a guide.
- D. No single butterfly has made the trip before to lead others.

Passage 2

Building Toward the Sky

History And Engineering · Level 3 · 181 words · 5 questions

For most of history, the height of a building was limited by its walls. In traditional construction, thick stone or brick walls carried the weight of everything above, so a taller structure needed an ever-heavier base. Beyond a certain point, the lowest walls grew so massive that adding floors became impractical. Two inventions removed the ceiling on height. [A] Engineers began framing buildings with rigid steel skeletons that bore the load instead of the walls. [B] Freed from carrying weight, exterior walls could become thin curtains of glass and stone. [C] Meanwhile, the safety elevator made the upper floors reachable and even desirable. [D] What had once been an exhausting climb turned into a brief, comfortable ride. These towers reshaped cities. By stacking offices and apartments upward, they packed far more activity onto costly downtown land. Their silhouettes became symbols of ambition and commerce, and the race to build higher pushed engineers to solve new problems of wind, foundations, and fire. The modern skyline, crowded with tall buildings, is the visible result of a quiet revolution in how weight is carried.

1. What can be inferred about buildings before steel framing?
- A.They could rise indefinitely with thin glass walls.
- B.They had no lower walls at all.
- C.They relied on elevators to carry their weight.
- D.Their maximum height was constrained by how much weight the walls could bear.Answer
Why D (Their maximum height was constrained by how much weight the walls could bear.) is the answer: The passage says walls carried the weight and grew impractically massive, limiting height.
- A. Thin glass walls came only after steel framing.
- B. Older buildings depended heavily on their lower walls.
- C. Elevators moved people, not building weight.
2. The word "impractical" in paragraph 1 is closest in meaning to
- A.beautiful
- B.expensive
- C.temporary
- D.unworkableAnswer
Why D (unworkable) is the answer: Massive base walls made adding floors unworkable, so 'impractical' means unworkable.
- A. Appearance is unrelated to the meaning.
- B. Cost is not the sense stressed; feasibility is.
- C. Duration is not what impractical means here.
3. What is the main idea of the passage?
- A.Elevators were invented before any tall buildings existed.
- B.Steel framing and the safety elevator allowed buildings to rise far higher and reshaped cities.Answer
- C.Thick stone walls are the best way to build tall structures.
- D.Cities became less crowded once towers appeared.
Why B (Steel framing and the safety elevator allowed buildings to rise far higher and reshaped cities.) is the answer: The passage credits steel skeletons and safe elevators with removing the height ceiling and transforming cities.
- A. The passage links elevators to reaching the new upper floors, not to preceding all tall buildings.
- C. Thick walls limited height, which the new methods overcame.
- D. Towers packed more activity onto downtown land, increasing density.
4. Look at the four markers [A], [B], [C], and [D] in paragraph 2. Where would the following sentence best fit? "With the frame doing the work, walls no longer had to grow thicker toward the ground."
- A.[C]
- B.[B]Answer
- C.[A]
- D.[D]
Why B ([B]) is the answer: The sentence follows the introduction of the steel frame and sets up the point that walls became thin, fitting at [B].
- A. At [C] the discussion has moved to elevators, breaking the topic.
- C. At [A] the frame has not yet been introduced, so 'the frame' has no referent.
- D. At [D] the elevator point is complete; the wall idea would be out of place.
5. According to paragraph 2, what allowed exterior walls to become thin?
- A.The building had fewer floors overall.
- B.The walls were made of heavier stone than before.
- C.The elevator supported the weight of the walls.
- D.A steel skeleton bore the building's load instead of the walls.Answer
Why D (A steel skeleton bore the building's load instead of the walls.) is the answer: The passage says the steel frame bore the load, freeing walls to become thin curtains.
- A. The frame allowed more floors, not fewer.
- B. Walls became thin curtains, not heavier stone.
- C. The elevator reached upper floors; it did not carry wall weight.

These are Reach120 practice passages written for the 2026 task format. None of them is a real TOEFL test item, and nothing on this page is published, licensed, endorsed or reviewed by ETS. Difficulty levels are our own bank’s values.

What Read an Academic Passage asks you to do

You read a multi-paragraph academic text — the kind of prose a first-year textbook uses — on a subject you are not expected to know anything about beforehand.
The questions cover stated detail, inference, the meaning of a word as the passage uses it, and the function of a sentence or paragraph within the argument.
Everything needed to answer is in the passage. Subject knowledge is never required, and relying on it is a reliable way to pick a wrong option.

What ETS states

The 2026 specification lists the Reading section at 50 items and 35 raw points, with task types Complete the Words, Read in Daily Life, and Read an Academic Passage.
These are published blueprint values, which the specification states are subject to minor revisions until the official launch. The item count includes non-scored items, so items do not equal raw points — the specification lists a maximum of 1 point per scored item.
The specification lists an estimated Reading time of an 18–21 minute router plus a 9 minute module, in a two-stage router-plus-module adaptive design.
The times are estimated. Reading prints a single 9 minute module for both routes, unlike Listening, which prints two discrete module lengths.
Reading items are machine-scored selected responses, evaluated by rule-based algorithms per the specification’s item-type notes.
Machine-scored is not exclusive to Reading and Listening — Build a Sentence is machine-scored too. This says nothing about how Reach120 scores your practice.

Sourced from the ETS 2026 test specifications, read 2026-07-27 (link confirmed 2026-08-24). Everything outside this box is Reach120’s own reading of it.

What the task actually measures

Whether you can hold the shape of an argument in mind across paragraphs, rather than answering each question from the sentence nearest to it.
Whether you separate what the passage states from what it implies, and both from what is merely consistent with it — the three categories most distractors are built to blur.
Whether you can read a word in the sense this passage gives it, which is often not the sense you learned first.

How Read an Academic Passage is scored

Each item has one keyed answer and is scored as a selected response, so an attempt is either right or wrong. What is worth studying is not the score but which distractor pulled you — the explanations below name the trap rather than repeating the key.

How to practice it

1Read the whole passage before the questions on this task type. Function and inference questions are unanswerable from a paragraph in isolation, which is the opposite of the daily-life task.
2After each paragraph, put its job in four or five words — what it adds to the argument, not what it is about. That note is what function questions are asking for.
3For every answer, find the line that supports it. If you cannot point at one, you have inferred further than the passage goes, which is what the trap options reward.
4On a vocabulary-in-context item, replace the word with your candidate and re-read the whole sentence. The right answer survives the sentence; the familiar answer often does not.
