What you will learn

  • Connect two stated facts to reach a supported conclusion.
  • Reject an answer that turns a limited claim into an absolute one.

A method you can repeat

  1. Underline the facts relevant to the question.
  2. Combine those facts without adding a new event, motive, or rule.
  3. Check strong words such as always, only, and everyone against the passage.

Worked example: follow the evidence

Read: The coordinator placed parcel K on the westbound rack. The loading plan assigned every parcel on that rack to van 2. The crew loaded parcel K according to the plan.

What can be concluded from the passage?

Supported answer: Parcel K was loaded into van 2.

Why it fits: K was on the westbound rack, all parcels on that rack were assigned to van 2, and the crew followed the plan for K.

Tempting wrong answer: Van 2 carried only westbound parcels.

Why it fails: The plan tells us where westbound parcels went. It does not tell us whether van 2 also carried other parcels. “Every westbound parcel went to van 2” does not mean “every parcel in van 2 was westbound.”

Before each answer: Ask: “Which facts support this answer, and what would I have to assume?”

Question 1: Supported inference

Question 1 · Supported inference · medium

Before opening a new exhibit, a museum invited volunteers to try its displays. Several volunteers who used wheelchairs reported that the information labels were mounted too high. They could approach the objects easily, but reading the small print required an uncomfortable upward angle. The museum lowered the labels and invited the same volunteers back for another visit. This time, the volunteers reported that they could read the descriptions without changing their seated positions.

What can reasonably be inferred about the lowered labels?

Choose an answer for question 1
Worked answer and explanation

Answer: D. They are likely easier to read from a seated position.

The labels were moved lower after seated volunteers found the high labels difficult to read. This supports improved readability from a seat. Neither the amount of text nor printing cost is discussed.

Question 2: Supported inference

Question 2 · Supported inference · hard

To learn whether passengers liked a revised bus route, a transit office distributed surveys on three weekday mornings. Most respondents approved of the change. The office initially described the result as a measure of all riders’ views. One analyst noted that evening and weekend passengers had not received surveys, even though those trips served a different mix of destinations. She recommended gathering responses during additional time periods before deciding whether the route should remain unchanged.

Which conclusion is best supported by the passage?

Choose an answer for question 2
Worked answer and explanation

Answer: B. The survey results may underrepresent riders who travel at other times.

Surveys were distributed only on weekday mornings, leaving other travel periods unsampled. That limits representation. The passage gives no weekend satisfaction results and no evidence that riders want the route removed.

Question 3: Supported inference

Question 3 · Supported inference · hard

A park office produced a simplified map that highlighted the main walking loops and restroom locations. Visitors found it easier to scan than the older map, which included every service track and elevation contour. However, volunteers who led longer hikes continued to use the detailed version. They said it helped them distinguish minor paths and identify landmarks away from the main loops. The office decided to keep both maps available and added a short description of each at the information desk.

What does the passage suggest about the two map versions?

Choose an answer for question 3
Worked answer and explanation

Answer: D. Each version may be useful for a different kind of trip.

One map supports finding main routes quickly, while the other supplies landmarks for minor paths. This implies usefulness depends on the trip. Crowding concerns readability, not whether the detailed map is accurate.

Question 4: Supported inference

Question 4 · Supported inference · hard

A team drafting setup instructions for a portable stage asked two experienced workers and three first-time volunteers to follow the draft. The experienced workers moved quickly but sometimes relied on steps they already knew. The new volunteers paused where the draft failed to identify a connector or specify which side faced upward. After watching both groups, the team added labels and clarified the order of assembly. It then asked a different group of new volunteers to try the revised instructions.

Why did the team include several readers in the trial?

Choose an answer for question 4
Worked answer and explanation

Answer: B. To see whether the instructions worked for people with different experience.

Experienced workers sometimes supplied steps from memory, while new volunteers exposed gaps in the written directions. Testing both groups helped the team make the instructions usable across experience levels. The revisions add clarity rather than remove familiar steps, and the trial is not a speed contest or a connector-selection process.

Question 5: Supported inference

Question 5 · Supported inference · hard

A materials team compared coated and untreated panels by exposing both groups to the same repeated cycles of simulated sunlight and water spray. The coated panels showed less fading after eight weeks. The team described the result as evidence that the coating reduced fading under the tested conditions. A reviewer asked whether the panels had also been frozen and thawed. They had not. The team scheduled a separate trial before making claims about use in climates with freezing winters.

Which conclusion is most justified by the passage?

Choose an answer for question 5
Worked answer and explanation

Answer: B. The test cannot show whether the coating improves performance in freezing conditions.

Both groups faced sunlight and water, but neither experienced freezing temperatures. The trial therefore cannot establish performance in freezing conditions. Lack of a freezing test does not prove the coating will fail in the cold.

Question 6: Supported inference

Question 6 · Supported inference · hard

A supply room once arranged all parts alphabetically. Workers could locate any label easily, but they repeatedly walked to the far wall for the same common items. After reviewing three months of requests, the supervisor moved the most frequently needed parts beside the packing tables. Rarely requested items took the more distant shelves. A posted directory showed every item’s new location. The room was no longer alphabetical, but the number of long trips during a typical shift decreased.

What can reasonably be inferred about the newer storage layout?

Choose an answer for question 6
Worked answer and explanation

Answer: D. It prioritizes frequently used parts over alphabetical order.

Frequent items move close to the tables while rarely used items occupy distant shelves, showing usage frequency guides placement. Alphabetical order is abandoned, and the passage explicitly says some items are farther away.

Question 7: Supported inference

Question 7 · Supported inference · hard

After a community center replaced its windows, its winter energy use fell compared with the previous year. The director credited the entire reduction to the new windows. A facilities analyst pointed out that the second winter was milder and the building had been closed for several extra weeks. She said the windows might have helped, but the comparison mixed several changes. To estimate the windows’ contribution more carefully, the center would need to consider weather and occupancy as well.

Which conclusion is most strongly supported?

Choose an answer for question 7
Worked answer and explanation

Answer: A. The lower energy use alone does not establish that the new windows caused all of the savings.

The comparison spans winters with different weather and occupancy, both identified as other influences. That limits the claim that the windows caused all the savings. The second winter was milder, and occupancy is explicitly relevant. The passage gives no isolated evidence that the new windows increased energy use; that claim is unsupported, rather than disproved by the overall decrease.

Question 8: Drawing a conclusion

Question 8 · Drawing a conclusion · hard

A sail-repair team compared two patching methods on worn practice sails. The first method took less time to apply and closed each tear, but several patches began lifting after repeated use. Those sails needed additional repairs. The second method took longer at the start, yet its patches remained attached throughout the observation period. The team decided to record both initial repair time and follow-up work when comparing the methods, rather than judging efficiency from the first repair alone.

Which conclusion best follows from the passage?

Choose an answer for question 8
Worked answer and explanation

Answer: A. A faster initial repair method may require more work over repeated uses.

Some quickly applied patches began lifting after repeated use and needed follow-up repairs. The slower method’s patches stayed attached during the observation period, so initial speed alone does not establish the lower total workload. The passage does not establish that any repair will last indefinitely.

Question 9: Supported inference

Question 9 · Supported inference · medium

The bookshop had a clean copy of the travel book, complete with a bright cover and an intact map. Ren set it down and returned to the worn copy she had brought from home. Its spine was cracked, and half the map was missing. Along the margins, however, were the tiny boats her father had drawn while reading to her. Beside one difficult place name he had written a pronunciation in his hurried script. Ren closed the book carefully and carried it home without making a purchase.

What can reasonably be inferred about why Ren values this copy of the book?

Choose an answer for question 9
Worked answer and explanation

Answer: D. It preserves a personal connection with her father.

Ren chooses the damaged copy because it contains the marks and drawings her father added. Those details support a personal connection. The condition is worn, a missing map suggests it is less complete than the shop copy, and nothing identifies the book’s author as its giver.

Question 10: Supported inference

Question 10 · Supported inference · hard

An archivist finds a program for an April 6 concert at Marlow Hall. Printed four days before the event, it lists a piano duet followed by a flute solo. A diary entry headed April 7 begins, “Last night at Marlow Hall, rain drummed against the windows. After the flute solo, the piano duet began, its first notes almost lost beneath the storm.” The writer then describes walking home and says nothing about the remaining music. No recording survives, and the collection contains no other report of the performance or explanation of the musicians’ decisions.

Which conclusion is most justified by these records?

Choose an answer for question 10
Worked answer and explanation

Answer: C. The performed order may have differed from the order printed in advance.

The April 7 diary’s reference to “last night” at the same hall points to the April 6 concert. It reports the flute solo before the duet, while the earlier printed program lists the reverse order. These records support a possible change in performed order. They do not explain why it changed, establish a different concert date, or provide a complete account of the music. The qualified word may avoids treating one attendee’s account as conclusive proof.

Question 11: Drawing a conclusion

Question 11 · Drawing a conclusion · hard

A translator can match every word in a sentence and still lose what the sentence does. An unexpected detail placed at the end may surprise the original reader, while the same word order in another language can sound merely awkward. Moving that detail may therefore preserve an effect that a mechanical match would destroy. This does not give translators permission to replace an author’s ideas with their own. It asks them to distinguish the arrangement of the words from the work those words perform, including emphasis, hesitation, and surprise.

With which statement would the author most likely agree?

Choose an answer for question 11
Worked answer and explanation

Answer: D. Preserving a passage’s effect may require changing its sentence structure.

The author argues that meaning includes emphasis and surprise, which can depend on sentence structure. A translator may therefore need a different structure to preserve the original effect. Matching individual words alone is presented as insufficient, not as a guarantee of faithfulness. The passage neither forbids structural changes nor restricts enjoyment to bilingual readers.

Question 12: Inference

Question 12 · Inference · easy

The order for the courtyard bench surprised the carver. Most customers asked to see his book of decorative patterns, but this customer left it closed. She wanted broad, plain slats and fastenings that could be reached easily if a board needed replacement. When he offered to carve leaves along the back, she asked whether the carving would make the bench harder to clean. They returned to discussing how it would stand up to everyday use outdoors.

What does the passage suggest is most important to the customer?

Choose an answer for question 12
Worked answer and explanation

Answer: C. Practical use and convenient upkeep.

The customer emphasizes reachable fastenings, replacement of boards, cleaning, and everyday outdoor use. These details support a concern for function and maintenance. She does not request the leaf pattern and questions its practical effect. The passage gives no deadline or concern about completion time. She asks for plain, usable features rather than uniqueness.

After this set: choose one missed answer and name the exact mistake: an added assumption, a lost condition, a detail mistaken for the main idea, or another mismatch with the text. Explain the correction in your own words before trying the next set.
