3.3 Focus: Adding, Retaining, and Deleting for Relevance
Key Takeaways
- The official Focus skill covers adding, revising, retaining, or deleting information for the sake of relevance to topic and purpose.
- Relevance is judged against the paragraph's stated purpose, not against whether the sentence is true or interesting.
- A sentence that is accurate, well written, and topically adjacent is the classic wrong answer on deletion questions.
- Addition questions supply a proposed sentence and a stated goal; the sentence must serve that specific goal, not the passage generally.
- Yes/No answer pairs are scored on their reasoning clause, so the justification must be correct and not merely the yes-or-no verdict.
The Sub-Skill That Asks "Should This Exist?"
The Development category contains three sub-skills. Proposition and Support concern what a text asserts and what backs it up. Focus asks a blunter question:
Focus: The student will add, revise, retain, or delete information and ideas in text for the sake of relevance to topic and purpose.
Four verbs — add, revise, retain, delete — and one criterion: relevance. Not accuracy. Not interest. Not elegance. Relevance to the topic and purpose at hand.
This is the sub-skill that most reliably separates strong writers from strong grammarians, because it cannot be resolved by a rule. It requires holding the paragraph's purpose in mind and testing a sentence against it.
The Relevance Test
For any candidate sentence, run three checks in order:
- What is this paragraph's job? State it in one clause. ("This paragraph explains why the reservoir project was delayed.")
- Does the sentence advance that job? Does it develop, support, exemplify, or qualify the paragraph's point?
- What breaks if it is removed? If the paragraph reads as well or better without it, delete.
Step 1 is the one people skip, and skipping it makes steps 2 and 3 unanswerable.
Why Good Sentences Get Deleted
The hardest deletion questions offer a sentence that is true, well written, and topically adjacent. Students protect it because nothing is wrong with it. But "nothing is wrong with it" is not the standard — relevance is.
The reservoir project stalled for eighteen months after engineers discovered unstable substrate beneath the eastern embankment. Remediation required injecting a cement-bentonite slurry to depths of forty feet. The reservoir is named for Amelia Hartwell, the county's first elected water commissioner. Only after core samples confirmed stability did construction resume.
The bolded sentence is accurate, cleanly written, and about the reservoir. It is also the correct deletion. The paragraph's job is explaining the delay and its remediation; the naming history serves that job in no way, and it interrupts the sequence between remediation and resumption.
Recognize this shape: a factual aside about origins, naming, biography, or trivia, dropped into a paragraph doing analytical or procedural work.
Common Irrelevance Patterns
| Pattern | Example Insertion | Why It Fails |
|---|---|---|
| Interesting aside | Naming or founding trivia | True, but serves no paragraph function |
| Topic drift | A sentence about a related but different subject | Moves off the paragraph's stated point |
| Premature detail | Specifics belonging to a later paragraph | Right passage, wrong location |
| Redundant restatement | Repeats a point already made | Adds no new information |
| Scope violation | Broadens from the case at hand to the field generally | Changes what the paragraph is about |
Question Format One: Deletion
The writer is considering deleting the underlined sentence. Should the sentence be kept or deleted?
Answer choices come as Yes/No pairs with reasoning:
- A. Kept, because it provides context that supports the paragraph's explanation of the delay.
- B. Kept, because it introduces the county official who authorized the project.
- C. Deleted, because it interrupts the paragraph's account of the delay with unrelated background.
- D. Deleted, because it repeats information stated earlier in the paragraph.
The decisive move: the reasoning clause is what is scored. Reaching the right verdict with the wrong justification earns nothing. In the example above, C and D both say "Deleted" — but D's reasoning is false, because the naming fact was not stated earlier. Only C is correct.
So the procedure is: decide keep-or-delete, eliminate the two choices with the opposite verdict, then evaluate the two surviving reasoning clauses as factual claims about the passage. One will be checkable and true; the other will be checkable and false.
Question Format Two: Addition
At this point the writer wants to add a sentence that would [specific goal]. Which choice best accomplishes this goal?
The stem states a goal, and the goal is the entire question. A choice can be well written, relevant to the passage, and still wrong because it does not do the specific thing asked.
Goal: add a sentence that provides a concrete example of the remediation technique described.
- A. Engineering challenges of this kind are common in reservoir construction. → General; no example.
- B. Crews drilled eighty injection points on a twelve-foot grid across the embankment. → Concrete and it exemplifies the technique. ✓
- C. The delay frustrated residents who had been promised water service by spring. → Relevant to the passage, but not an example of the technique.
- D. Cement-bentonite slurry has been used in civil engineering since the 1950s. → Background about the material, not an example of its use here.
B is correct. C is the most tempting distractor because it is genuinely relevant to the passage — just not to the stated goal.
Method: underline the goal in the stem before reading the choices, then test each choice against that goal alone.
Focus at the Whole-Text Level
A smaller number of items apply the same logic to entire paragraphs — asking whether a paragraph belongs, or where it should sit. The test is identical, one level up: what is the passage's purpose, and does this paragraph advance it?
A passage arguing that a city should expand bus service does not need a paragraph on the history of streetcars, however well written, unless that history is used to support the argument.
The Governing Instinct
When you cannot decide, ask: if I removed this, would a reader notice anything missing from the argument? If the honest answer is no, it goes. Focus questions reward writers who are willing to cut good sentences, and that willingness is the actual skill being measured.
A paragraph explains how a museum reduced its energy costs through a lighting retrofit. Which sentence is the strongest candidate for deletion?
On a deletion question, a student correctly determines that a sentence should be deleted. Two answer choices both begin "Deleted." How should the student choose between them?
A stem reads: "The writer wants to add a sentence that emphasizes the scale of the volunteer response." Which choice best accomplishes that goal?
