Restoring a River: Inference and Attitude in a Short Argument
When a mid-sized town announced that it would restore the river running through its old quarter, the engineers promised measurable outcomes: dissolved oxygen up, coliform counts down. Three years and a great deal of concrete later, both targets had been met. Yet the river is now a channel - straight, embanked and lifeless at noon. The fish that did return were found in the stretches where the embankment was never built, reaches that the final report classifies as "incomplete". None of this is an argument against measurement. It is an argument against treating a single index as though it were a description of a system. Indices are chosen because they can be counted, and they are counted because someone, somewhere, must be held accountable. The trouble begins when accountability hardens into a conviction that what has not been counted has not happened. A town that measures its river by oxygen alone will eventually build a river that produces oxygen and nothing else.
1. Which of the following best states the author's attitude towards the engineers' targets - hostile, approving, or something else? Justify your answer with the text.
Read the worked answer
Neither hostile nor approving: the author accepts the targets as necessary but rejects them as sufficient.
The decisive sentence is "None of this is an argument against measurement." An author who wanted to condemn the engineers outright would not concede that much; the concession is what makes the criticism bite. The targets were, on their own terms, achieved - oxygen rose, coliform fell - and the author does not dispute the data.
The objection is aimed at a different level: at "treating a single index as though it were a description of a system". The engineers are not accused of dishonesty or incompetence but of a category error, mistaking a proxy for the thing it proxies. The closing line ("a river that produces oxygen and nothing else") is ironic rather than angry - it shows the target being met perfectly, and shows that perfect compliance is the problem.
So the correct label is critical but sympathetic to measurement itself. An option saying the author 'opposes quantification' or 'believes the targets were not met' would be a misreading of the same intensity that a careless reader produces from the word 'lifeless'.
2. Why does the author put the word "incomplete" in quotation marks? What does this reveal about the report's classification?
Read the worked answer
The quotation marks signal that the word is the report's word, not the author's, and that the author is holding it at arm's length.
What the report calls "incomplete" is the stretch of river where the embankment was never built - and that is precisely where the fish came back. The label is therefore an artefact of the project's own scope: anything the concrete did not reach is scored as unfinished by definition, regardless of its ecological condition. The vocabulary of completion has been silently substituted for the vocabulary of health.
The effect is ironic. The project's failures are filed under success (targets met) and its only ecological successes are filed under failure ("incomplete"). The scare quotes warn the reader that if you accept the report's categories uncritically, you will count the fish and still conclude there are none.
3. A town council proposes to grade all its public parks solely on annual visitor footfall, with funding tied to the score. Using the passage's reasoning, predict the likely consequences and identify what the scheme would fail to register.
Read the worked answer
Applying the passage's logic - an index becomes the goal, and the system is reshaped to produce the index - the prediction is that parks would be redesigned for throughput: wider paved entrances, food stalls, event lawns, floodlighting for evening crowds, and anything that raises the turnstile count.
What the score cannot register is exactly what makes a park good for the people who use it quietly: shade, birdsong, unprogrammed space, a bench where nothing is expected of you. Those features would not merely go unrewarded, they would be actively competed away, because a hectare of meadow scores zero while a hectare of car park scores thousands.
The sharpest consequence follows from the passage's closing line: a genuinely excellent, low-traffic park - a wetland reserve, say - would be graded a failure and defunded, while a concrete plaza with a coffee kiosk would be graded a triumph. Note the structure of the argument: the author never says footfall is a bad thing to know, only that funding it as though it were the definition of a good park converts a useful measure into a distortion. The remedy implied is to keep several measures in play and to treat the uncounted as real.
