Reading and Writing: Craft and Structure, 3 original questions

SAT Text Structure and Purpose Practice: Questions and Answers

Practice SAT text structure and purpose with three original passages. Identify what a sentence does, follow the argument and explain each answer.

The short answer

Text structure and purpose questions ask how a passage works, not merely what it mentions. Track the job of each sentence: introduce an issue, describe a method, provide evidence, contrast an idea or qualify a claim. For an underlined sentence, explain how it connects the surrounding ideas. For an overall-structure question, summarize the sequence of moves across the passage. Choose the answer that describes those moves at the right scale. A detail can be factually accurate without explaining why the writer included it.

Step-by-step method

Use these steps in order, then apply them to the questions below.

  1. Step 1: Identify the scope

    Decide whether the question targets one sentence or the passage’s overall organization. Do not substitute a whole-passage purpose for a local sentence function.

  2. Step 2: Label the moves

    Use simple verbs such as proposes, tests, contrasts, illustrates or limits. These describe what the writer is doing.

  3. Step 3: Check the neighbors

    For a sentence-function question, read the preceding and following sentences. A sentence’s role depends on how it changes or develops those ideas.

  4. Step 4: Translate the choice

    Match an answer’s abstract language to actual sentences. If it says an objection is answered, locate both the objection and the response.

Question 1 of 3

Original passage

In a fictional planning exercise, a team’s first model treated every open lot as equally suitable for a small garden. Field inspections, however, revealed that several lots received little sunlight. The team therefore added sunlight measurements before deciding which lots to use.

What is the main function of the second sentence?

Choose an answer for question 1
View worked answer for question 1

Correct answer

Choice C: It describes a limitation in the first model that leads to a change in the team’s method.

Explanation

The second sentence identifies a factor the first model missed: sunlight. The final sentence shows the resulting change, adding sunlight measurements. Its function is to expose a limitation and motivate that revision. The team improves its method rather than rejecting modeling or abandoning every lot.

Why each choice is right or wrong

  1. Choice A

    Sunlight suitability directly concerns the model and lot selection; it is not an unrelated benefit.

  2. Choice B

    One model’s limitation does not establish that all modeling is useless.

  3. Choice C

    Correct answer

    The sunlight finding limits the first model and explains the subsequent methodological change.

  4. Choice D

    The passage says several lots had little sunlight, not that every lot was rejected.

Question 2 of 3

Original passage

A fictional classroom trial asked whether a larger label would help readers find a shelf more quickly. Two otherwise identical shelf displays used different label sizes. Readers found the shelf in nearly the same amount of time with either display. The trial’s result did not support the expected benefit of the larger label.

Which choice best describes the passage’s overall structure?

Choose an answer for question 2
View worked answer for question 2

Correct answer

Choice A: It states a question, describes a comparison, and reports a result that does not support the anticipated effect.

Explanation

The first sentence gives the question, the second describes the comparison, and the last two report and interpret the outcome. Similar times fail to support the predicted advantage of a larger label. The passage neither ranks many styles nor establishes a universal conclusion, and the trial is described as completed.

Why each choice is right or wrong

  1. Choice A

    Correct answer

    This follows the actual order and accurately characterizes the reported outcome.

  2. Choice B

    Only two otherwise identical displays are compared; no popularity ranking is given.

  3. Choice C

    The passage begins with a question, and the limited trial does not prove agreement among all readers.

  4. Choice D

    The comparison precedes the result and is described as having already taken place.

Question 3 of 3

Original passage

A fictional community archive once filed every photograph under the year it was received. A reader searching for photographs of a particular street had to open many yearly folders. To address that problem, the archive added a street-name index while retaining the original folders.

Why does the writer describe the reader’s search in the second sentence?

Choose an answer for question 3
View worked answer for question 3

Correct answer

Choice D: To illustrate a difficulty that the new index is intended to address.

Explanation

The reader’s time-consuming search makes the weakness of year-only filing concrete. The final sentence answers that difficulty with a street-name index. The example supplies a reason for the change; it does not discuss the relative value of record types or determine when the photographs were taken.

Why each choice is right or wrong

  1. Choice A

    The passage does not compare photographs with written records.

  2. Choice B

    The final sentence says the original folders were retained, not removed.

  3. Choice C

    The folders use the year of receipt, and no exact photography date is established.

  4. Choice D

    Correct answer

    The search illustrates the retrieval problem that motivates the street-name index.

Common mistakes

  • Choosing a topic summary instead of a function: say what the sentence does with the topic.

  • Calling any contrast a refutation: a qualification may limit rather than overturn a claim.

  • Ignoring order: an answer that reverses the passage’s sequence misdescribes its structure.

Common questions

How is purpose different from main idea?

A main idea describes the central message. Purpose describes what the writer aims to accomplish, such as explaining a change or challenging an assumption.

Should I focus on contrast words such as however?

They are useful signals, but read what is being contrasted. The word alone does not tell you whether the author rejects a claim, adds a limitation or reports a surprising result.

How can I check an overall-structure answer?

Map each part of the answer to the passage in order. Reject an option that invents a step, omits the central move or reverses the sequence.
