Reading the Tree-Canopy Passage: What the Author Actually Claims
A student annotates this passage in the margin: "The author thinks the tree program is a failure."
"In 2016 the city of Ralston began replacing its street trees, citing shade and storm-water benefits. Six years later, canopy coverage is up 11 percent in the three neighborhoods that received new plantings, and summer surface temperatures there are measurably lower than on untreated blocks. Critics note that the city has never published a cost-per-tree figure and that young trees need decades of watering before they deliver the benefits promised. City staff respond that the watering budget has been approved every year and is fully funded."
The student's notes will be used to answer inference items, so the difference between what the passage states and what it merely permits matters.
1. Evaluate the student's margin note. Is "the author thinks the program is a failure" a defensible reading?
Read the worked answer
No - it is unsupported. The author reports an 11 percent canopy increase and measurably lower surface temperatures, which are positive outcomes stated as fact. The critics' objections are attributed ("Critics note..."), not endorsed. The author never evaluates the program.
What the author's stance actually is: neutral reporting of a dispute - results on one side, unquantified costs and a long payoff horizon on the other, plus a staff response.
Why the student went wrong: the note converts the presence of criticism into the author's verdict. Quoting critics is not agreeing with them. A reader who carries this error into an inference item will pick the choice that says the author is skeptical.
2. What can be validly inferred about the critics' position, and what would be an overreach?
Read the worked answer
Valid inferences:
- They want cost transparency that the city has not provided ("never published a cost-per-tree figure").
- They are measuring the program on a longer timeline than six years ("decades of watering").
- They accept, or at least do not dispute, that benefits exist; their objection is about accounting and timing.
Overreaches:
- "The critics oppose the program." The passage gives no such statement; wanting data is compatible with supporting the program.
- "The critics say the trees will never pay off." The text says benefits take decades, not that they never arrive.
- "The critics are wrong because the budget is funded." That answers a different objection.
Rule: an inference must be forced by the text. Each valid item above is checkable against a specific phrase; each overreach adds a belief the passage never expresses.
3. How well does the city staff's response answer the critics, and what does that tell you about the passage's balance?
Read the worked answer
Partly. Staff address the funding worry: the watering budget exists and is renewed annually. That is a real answer to "who pays for decades of watering."
But it does not answer the main criticism. The critics asked for a cost-per-tree figure. Confirming that watering is funded says nothing about total cost per tree, and the passage never supplies that number.
Implication for reading: the response is narrower than the objection, which is a common structure - the passage presents a partial rebuttal and leaves the strongest criticism standing. Balance here means both sides are represented, not that they are equally answered. A question asking "which criticism remains unaddressed" has a clean textual basis; one asking "who wins the argument" does not.
