1. What you will learn

Choose a method from the question's conditions before opening feedback. Work without notes first, then explain which restriction or evidence determined your answer. These are original instructional questions, not an adaptive test or a predictor of an official score.

2. Practice

Read the shared passage and answer every question. Each question is graded separately; select-all questions require the exact set.

An economic historian used surviving advertisements to estimate the availability of imported cloth in a port. The number of advertisements increased after a tariff reduction, suggesting greater trade. But advertisements measure sellers' efforts to attract buyers, not quantities sold. More intense competition could increase advertising even if imports remained stable. The historian therefore compared the advertisements with warehouse records. Both sources rose in the same years, strengthening the trade interpretation. Their agreement is useful precisely because the two records arise from different activities and are vulnerable to different distortions.

Which statement best expresses the passage's main point?

Independent records strengthen an interpretation that advertisements alone cannot securely establish.
Advertisements directly measure the quantity of goods sold.
Tariff reductions always leave imports unchanged.
Warehouse records make every other historical source useless.
Competition cannot affect advertising.

Which conclusion is best supported by the passage?

Agreement between sources is more informative when their possible biases differ.
Both sources were produced by the same advertising office.
All increases in advertising reflect increased imports.
The tariff reduction proves that competition declined.
Warehouse records show consumer preferences directly.

Select all statements supported by the passage.

Advertisements increased after the tariff reduction.
Warehouse records supported the timing of the increase.
The passage treats advertising counts as direct sales totals.

3. Practice

Read the shared passage and answer every question. Each question is graded separately; select-all questions require the exact set.

Engineers tested a coating that reduced heat absorption on roof tiles. In a laboratory, coated tiles stayed cooler under a lamp than uncoated tiles. A field trial found a smaller difference. Dust had accumulated on both surfaces, and the coated roofs were shaded for part of the day. These conditions do not invalidate the laboratory result; they change the circumstances under which it is applied. For a building owner, the relevant question is not simply whether the coating works under ideal conditions, but how much benefit remains under local conditions and what maintenance is needed to preserve it.

Which statement best expresses the passage's main point?

Laboratory efficacy and practical benefit are distinct questions that require attention to field conditions.
The field trial proves the laboratory measurements were fabricated.
Dust affects only uncoated tiles.
Shading makes all roof coatings harmful.
Building owners need no information about maintenance.

Which conclusion is best supported by the passage?

The size of the laboratory effect should not automatically be assumed for every roof.
Cleaning would certainly restore the full laboratory effect.
The coating increased field temperatures above uncoated roofs.
The lamp generated no heat.
All local conditions were controlled in the field trial.

Select all statements supported by the passage.

The field difference was smaller than the laboratory difference.
Some coated roofs experienced shade.
The field trial identified dust as the sole cause of the difference.

4. What you can do now

Classify each error as interpretation, method, execution or response format. Revisit the relevant worked lesson, then retry after a study gap. A remembered item is review, not fresh assessment evidence.
