Words in context
Choose the meaning that fits the passage’s logic and tone.
Predict first
Cover the choices and predict a simple word from nearby clues. Then look for the option that preserves that meaning.
Multiple meanings
A familiar word can have a less familiar academic meaning. “Qualified” can mean limited or modified, not just certified.
Meaning comes from use, not familiarity
A word can have several meanings, and the sentence selects among them. Nearby contrasts, examples, and causes narrow the intended meaning. Replace the target with a simple phrase you understand before looking for a more formal equivalent among the options.
Check tone and degree as well as definition
Two words may both suggest disagreement but differ in intensity: “question” is milder than “denounce.” The choice must fit how strongly the author speaks. Read the whole sentence with the replacement to check its logical relationship and grammatical fit.
Worked example
“The results were preliminary, so the scientist offered a qualified endorsement.”
- “Preliminary” signals uncertainty.
- The endorsement is therefore limited rather than unconditional.
Here, “qualified” means restricted or cautious.
Watch for this: Do not choose a dictionary meaning that conflicts with the sentence’s contrast, cause, or emphasis.
Check your understanding
The fragile first model broke easily, but the revised model was robust. In context, “robust” most nearly means
- durable
- colorful
- temporary
- mysterious
Show answer and explanation
Answer: A. “Durable” fits the contrast with “fragile” and resistance to breaking.
Text Structure and Purpose
Text structure and purpose
Describe what a sentence does in the author’s argument.
Content versus function
Content is what the sentence says. Function is its job: introduce a claim, give evidence, define a term, offer a counterexample, or qualify a conclusion.
Track the structure
Read the sentences before and after the selected part. A counterexample often challenges a generalization; a qualification narrows a claim.
Function is the job a statement performs
A sentence may describe an experiment, but its function could be to supply evidence, introduce a problem, or challenge a previous claim. Function answers begin with actions such as illustrates, qualifies, contrasts, or defines. Identify the author’s developing point before naming a sentence’s role.
Track changes in direction
Words such as however, for example, and therefore often signal a move from claim to challenge, generalization to illustration, or evidence to conclusion. Those markers are clues, not substitutes for reading. A qualification limits a claim while preserving part of it; a contradiction rejects it.
Worked example
“Many assume all deserts are hot. Some deserts have freezing winters. Low precipitation, not temperature, defines a desert.” What does the second sentence do?
- The first sentence gives a common belief.
- The second provides a case that contradicts that belief.
It offers a counterexample to a common assumption.
Watch for this: Choose a description of the sentence’s role, not a paraphrase of one detail.
Check your understanding
“The initial experiment suggested a benefit. However, the sample was small.” What is the function of the second sentence?
- It proves the benefit is universal.
- It defines an experiment.
- It introduces an unrelated topic.
- It identifies a limitation of the evidence.
Show answer and explanation
Answer: D. The sentence points out a reason to be cautious about the initial finding.
Cross-Text Connections
Connect two texts
Compare the authors’ claims without inventing agreement or disagreement.
Summarize separately
Write each author’s main claim in a few words before comparing them.
Identify the relationship
An author may agree with a benefit yet point out a limitation. Qualified agreement is different from complete rejection.
Give each author a separate position
Text 1 and Text 2 can share a topic while disagreeing about its interpretation. Summarize each author’s main claim and level of certainty separately. Do not merge them into one view before deciding who agrees, objects, or supplies a limitation.
Respond to the exact claim named in the question
A question may ask how one author would respond to a particular sentence rather than the entire other text. Find that claim and compare it with the responding author’s evidence. A response can accept a result while disputing its explanation or broad applicability.
Worked example
Text 1 favors chronological museum displays for historical context. Text 2 acknowledges that benefit but favors themed displays for cross-period connections.
- Both recognize a benefit of chronology.
- Text 2 adds something a chronological display may miss.
Text 2 would accept a benefit while identifying a limitation.
Watch for this: Check which author the question asks you to speak for. Do not swap their positions.
Check your understanding
Text 1 says urban gardens provide fresh food. Text 2 agrees but notes that limited land restricts how much food they can supply. How does Text 2 respond?
- It denies that gardens grow food.
- It accepts the benefit while limiting its scale.
- It claims gardens supply all urban food.
- It changes the subject to rural highways.
Show answer and explanation
Answer: B. It agrees on the benefit and adds a constraint on the quantity supplied.
