What you will learn

  • Distinguish “happened before” from “caused.”
  • Compare two methods using the same stated feature.

A method you can repeat

  1. List the steps or events in order.
  2. Find language that explicitly connects a cause to an effect.
  3. For a comparison, check that both sides discuss the same feature and conditions.

Worked example: follow the evidence

Read: The team first moved the storage cabinet and then replaced a damaged hose. A later inspection found no leak. The report attributed the repair to the new hose and noted that moving the cabinet had simply made the hose easier to reach.

According to the report, why did the leak stop?

Supported answer: The damaged hose was replaced.

Why it fits: The report identifies the new hose as the repair. Moving the cabinet was an earlier step that provided access, not the stated cause of the leak stopping.

Tempting wrong answer: Moving the cabinet stopped the leak.

Why it fails: The cabinet was moved before the successful inspection, but order alone does not establish cause. The passage gives a more specific explanation.

Before each answer: Ask: “Does the passage say this caused the result, or only that it happened first?”

Question 1: Sequence and cause

Question 1 · Sequence and cause · easy

Nora’s note asked Dev to use the lane behind the bakery because the square was crowded with stalls. The messenger arrived after Dev had already left home. Unaware of the request, Dev crossed the square by his usual route and met an old neighbor beside a stall. They had not arranged to meet. Later, when Nora showed him the note, he realized that following its directions would have taken him away from that chance encounter.

Why did Dev use the route on which he met his neighbor?

Choose an answer for question 1
Worked answer and explanation

Answer: B. The suggested alternative reached him too late to affect his departure.

The note arrives after Dev leaves, leaving him to follow his usual route and encounter the neighbor by chance. The messenger arrived after Dev had already left, so he was unaware of the request. The passage states that the meeting was not arranged. The note asked him to take the lane behind the bakery, not to seek a neighbor in the square.

Question 2: Sequence and cause

Question 2 · Sequence and cause · easy

For the first portrait photograph, a lamp stood to Mei’s left. A shadow from her nose fell across the opposite cheek. The photographer then moved the same lamp to her right and took another photograph. Mei kept her head in the same position, and neither the chair nor the camera moved. In the second photograph, the nose’s shadow fell toward the other side of her face. The two prints were placed together for comparison.

What changed condition explains the different direction of the shadow?

Choose an answer for question 2
Worked answer and explanation

Answer: B. The lamp illuminated Mei’s face from the other side.

The lamp’s position is the stated change between the photographs, and it changes the direction from which light reaches the face. The passage states that Mei kept her head in the same position. Neither the camera nor the chair moved. The photographer moved the same lamp; no second lamp was added.

Question 3: Sequence and cause

Question 3 · Sequence and cause · medium

In a weaving sample, the crosswise yarn must travel over and under the lengthwise threads. It therefore needs some allowance rather than being pulled straight and taut from edge to edge. During one section, the weaver pulled each new row more tightly, leaving less of that allowance. The sides of the sample began drawing inward. She left the frame and the lengthwise threads in place, then returned to her earlier, looser placement of the crosswise yarn for the next section.

What stated change led to the sides drawing inward?

Choose an answer for question 3
Worked answer and explanation

Answer: D. The crosswise yarn was pulled tighter, reducing the allowance for its path.

Tighter placement removes some of the length needed for the crosswise yarn’s path, matching the stated inward drawing of the sides. The passage states that the frame remained in place. No added lengthwise threads are described; their arrangement is left in place. Its over-and-under path remains the reason an allowance is needed.

Question 4: Sequence and cause

Question 4 · Sequence and cause · easy

From the valley road, Hal could see the high stone walls beside him but little beyond them. He walked up to the ridge that same morning. From there, the walls looked like lines dividing connected fields, and he could follow the stream through several of them. No wall had been removed and no field had changed during his walk. The higher position simply let him see relationships that the road had hidden.

Why could Hal see how the fields connected from the ridge?

Choose an answer for question 4
Worked answer and explanation

Answer: C. His higher viewpoint revealed more of the landscape beyond the roadside walls.

The change is in Hal’s position, not in the walls or fields, so the new view reveals existing relationships. The passage explicitly says no wall was removed. No change in the stream’s course is described; Hal’s viewing position changes. The walls still divide the fields when Hal sees them from above.

Question 5: Sequence and cause

Question 5 · Sequence and cause · hard

To travel upstream through this lock, a boat first enters from the lower stretch of canal. Both sides of the entry gates are then at the lower water level. Once the boat is inside, those gates close. Small panels in the upper gates are opened to admit water; the upper gates themselves remain shut while the chamber fills. The rising water lifts the boat. A crew member coils a spare rope during this interval, but finishing that task does not determine when the gates may open. The upper gates open only after the chamber’s water matches the higher canal level, allowing the boat to leave.

When the boat has begun rising but has not reached the higher canal level, which description is correct?

Choose an answer for question 5
Worked answer and explanation

Answer: C. The entry gates have closed, the upper gates remain shut, and water enters through their small panels.

The stated interval falls after the entry gates close and panels open, but before equal water levels permit the upper gates to open; the rope task is concurrent rather than a prerequisite. The entry gates close before filling, and the upper gates open only after the levels match. The upper gates remain closed during the rise, and the rope task does not control their opening. During the rise, the panels admit water while the upper gates themselves remain shut.

Question 6: Sequence and cause

Question 6 · Sequence and cause · hard

Both routes leave from Cedar and reach the same museum. The Hill bus departs first, passes several villages, and reaches the museum after the Marsh connection is scheduled to arrive. Hill passengers remain in one vehicle. The Marsh route departs Cedar later and uses two buses, with a change at Pine. Its earlier arrival depends on catching the second bus there; the timetable leaves only a short interval for that change. If the connection is missed, the next Marsh arrival is later than the Hill bus. No fares or walking distances within Pine station are listed in the information provided.

Which comparison accurately preserves the passage’s qualifications?

Choose an answer for question 6
Worked answer and explanation

Answer: C. Marsh can arrive earlier despite leaving later, but requires a successful transfer; Hill avoids that change.

The scheduled order favors Marsh only if its transfer succeeds, while Hill’s later scheduled arrival comes with staying aboard one vehicle. A missed connection reverses the arrival order, and later departure alone does not cause earlier arrival. Passing villages does not imply changing buses; Hill passengers remain in one vehicle. Neither fares nor walking distances are supplied, and Hill does not require the Pine transfer.

Question 7: Sequence and cause

Question 7 · Sequence and cause · easy

After dyeing two small cloth samples, Elin laid one beside the other to compare their shades. One had already dried, but the second was still wet and looked darker. In this process the wet cloth would look lighter as it dried. Elin therefore put both on the drying rack before choosing between them. She made no change to the dye at that point; she first wanted to compare the samples in the same condition.

Why did Elin wait before choosing a sample?

Choose an answer for question 7
Worked answer and explanation

Answer: A. The wet sample’s appearance could change as it dried, making the initial comparison uneven.

Comparing one wet sample with one dry sample mixes conditions that affect apparent shade, so Elin waits until both are dry. The passage predicts a change in the wet sample’s appearance, not identical final colors. No dye change is made, and the rack is used for drying. The wet sample visibly looks darker; the issue is comparison under different conditions.

Question 8: Sequence and cause

Question 8 · Sequence and cause · medium

The cook’s notes for the fruit loaf begin by setting the dried fruit in a bowl of water. After soaking, the fruit is tipped into a strainer and left until the loose water has drained away. Only then is the amount needed for the loaf measured. Any fruit left over goes into a covered bowl for another dish. The measured portion is stirred into the prepared mixture; the soaking water is not added. The notes measure drained fruit, rather than reserving a measured dry portion at the beginning.

Which sequence follows the notes?

Choose an answer for question 8
Worked answer and explanation

Answer: D. Soak the fruit, drain it, measure the needed portion and add that portion to the mixture.

The passage gives a specific preparation sequence and identifies the measured material as fruit after soaking and draining. The notes soak and drain the fruit before measuring or adding it to the mixture. The loose water drains away before measuring, and the soaking water is not added. The needed portion is measured before addition, while extra fruit is set aside for another dish.

Question 9: Sequence and cause

Question 9 · Sequence and cause · medium

Rina kept two garden beds of the same variety of lettuce, with twelve plants in each by the end of planting. She set all twelve in the first bed on one morning. For the second, she planted three at a time on four weekly visits. Her notebook later recorded most of the first bed’s harvest within a short span, while harvests from the second extended across several weeks. The account lists the planting and harvest dates, but it gives no weights for the harvested leaves.

Which comparison is supported by the notebook as described?

Choose an answer for question 9
Worked answer and explanation

Answer: D. The bed planted in successive groups had a more spread-out harvest period, but the account does not establish which bed produced more by weight.

The observed difference concerns the distribution of harvest dates; equal plant counts and missing weight data limit the comparison. Both beds contained twelve plants by the end of planting. The passage describes the reverse timing pattern. No harvested weights are given, so the timing record cannot establish a weight advantage.

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.
