Questions & answers

Opening an answer records help for that question.

D01 · Warm-up

What a small set of sensors can tell us

What did the devices measure?

  1. Sound only when a delivery had been entered on the schedule.
  2. Residents’ ratings of how disruptive individual businesses were.
  3. The content of conversations after residents gave consent.
  4. Sound levels, without recording conversations.
Answer & explanation
Sound levels, without recording conversations.

The supported answer is “Sound levels, without recording conversations.”. Evidence: “The devices measured sound levels; they did not record conversations.”. Compare the alternative “The content of conversations after residents gave consent.”. This reverses the relationship stated in the passage. Compare the alternative “Sound only when a delivery had been entered on the schedule.”. This incorrectly limits recording to scheduled deliveries. The study also captured equally high peaks when no delivery was scheduled. Check the source wording “some equally high peaks occurred when no delivery was scheduled.” against the question and the claim “Sound only when a delivery had been entered on the schedule.”.

D02 · Warm-up

What a small set of sensors can tell us

Why did the team refuse to promise a policy outcome before measurement?

  1. The team had established that complaints were unrelated to actual sound levels.
  2. The devices measured daytime levels more reliably than evening levels.
  3. A fixed conclusion would undermine the investigation’s purpose.
  4. The original complainants no longer wanted the evening deliveries investigated.
Answer & explanation
A fixed conclusion would undermine the investigation’s purpose.

The supported answer is “A fixed conclusion would undermine the investigation’s purpose.”. Evidence: “If we had already decided what the result must mean, the measurements would have been little more than decoration.”. Compare the alternative “The team had established that complaints were unrelated to actual sound levels.”. This reverses the relationship stated in the passage. Compare the alternative “The original complainants no longer wanted the evening deliveries investigated.”. This adds a specific detail that the account does not provide; plausibility is not textual evidence.

D03 · Warm-up

What a small set of sensors can tell us

Does the limited recommendation dismiss residents’ complaints?

  1. The speaker treats readings as sufficient grounds to overrule residents’ experiences.
  2. No; the speaker explicitly distinguishes a limited conclusion from dismissing complaints.
  3. Yes; the sample’s limitations mean the complaints cannot inform future decisions.
  4. Yes; a recommendation is meaningful only if it demands the general ban.
Answer & explanation
No; the speaker explicitly distinguishes a limited conclusion from dismissing complaints.

The supported answer is “No; the speaker explicitly distinguishes a limited conclusion from dismissing complaints.”. Evidence: “it is not a claim that the complaints were unimportant.”. Compare the alternative “Yes; a recommendation is meaningful only if it demands the general ban.”. This reduces the argument to two opposing alternatives that the speaker or writer explicitly rejects. Compare the alternative “The speaker treats readings as sufficient grounds to overrule residents’ experiences.”. This reverses the relationship stated in the passage.

P01 · Build the skill

What a small set of sensors can tell us

What was a limitation of the recruited sample?

  1. Complainants and main-street windows were overrepresented.
  2. The additional side-street windows removed the initial imbalance entirely.
  3. Recruitment produced a balanced sample of homes throughout the district.
  4. Most volunteers had not previously complained about noise.
Answer & explanation
Complainants and main-street windows were overrepresented.

The supported answer is “Complainants and main-street windows were overrepresented.”. Evidence: “People who had complained were more likely to volunteer, and most available windows faced the main street.”. Compare the alternative “Recruitment produced a balanced sample of homes throughout the district.”. This extends a qualified finding into a claim without exceptions. Compare the alternative “Most volunteers had not previously complained about noise.”. This reverses the relationship stated in the passage.

P02 · Build the skill

What a small set of sensors can tell us

How did the diaries affect interpretation of loud peaks?

  1. They showed that equally high non-delivery peaks had not occurred.
  2. They supplied enough information to replace further recordings.
  3. They identified deliveries as the source of each individual high reading.
  4. They revealed other possible sources besides deliveries.
Answer & explanation
They revealed other possible sources besides deliveries.

The supported answer is “They revealed other possible sources besides deliveries.”. Evidence: “road repairs and a late public event were among the sources.”. Compare the alternative “They identified deliveries as the source of each individual high reading.”. This extends a qualified finding into a claim without exceptions. Compare the alternative “They supplied enough information to replace further recordings.”. This makes one indicator sufficient on its own, although the passage calls for a broader assessment.

P03 · Build the skill

What a small set of sensors can tell us

How does the speaker frame the first study’s role?

  1. As a representative measure of exposure in all homes in the district.
  2. As a more objective replacement for residents’ accounts of disturbance.
  3. As sufficient evidence to select a district-wide evening ban immediately.
  4. As a guide to further investigation, not a final resolution.
Answer & explanation
As a guide to further investigation, not a final resolution.

The supported answer is “As a guide to further investigation, not a final resolution.”. Evidence: “We are treating the first study as a guide to better questions, not a final answer to every dispute about noise.”. Compare the alternative “As sufficient evidence to select a district-wide evening ban immediately.”. This recommends acting before the further evidence or safeguards requested in the passage are available. Compare the alternative “As a more objective replacement for residents’ accounts of disturbance.”. This makes one indicator sufficient on its own, although the passage calls for a broader assessment.

What a small set of sensors can tell us

Why was a daily average alone insufficient?

  1. It could not provide a basis for comparing locations.
  2. It hid short but disruptive periods.
  3. It gave too much weight to the selection of main-street volunteers.
  4. It combined private speech with environmental sound readings.
Answer & explanation
It hid short but disruptive periods.

The supported answer is “It hid short but disruptive periods.”. Evidence: “A single daily average was easy to compare, but it concealed short periods that people found particularly disruptive.”. Compare the alternative “It combined private speech with environmental sound readings.”. This substitutes a different outcome for the one that was measured or reported. Compare the alternative “It gave too much weight to the selection of main-street volunteers.”. This substitutes a different outcome for the one that was measured or reported.

R02 · Related practice

What a small set of sensors can tell us

Why did the report avoid one combined disturbance score?

  1. It would conceal a judgement about the relative weight of disturbances.
  2. It would make the timing of a loud peak impossible to record.
  3. It would conceal the main-street imbalance in the volunteer sample.
  4. Residents had asked the team to remove all comparative averages.
Answer & explanation
It would conceal a judgement about the relative weight of disturbances.

The supported answer is “It would conceal a judgement about the relative weight of disturbances.”. Evidence: “that would have hidden a judgement about how much weight to give each kind of disturbance.”. Compare the alternative “It would conceal the main-street imbalance in the volunteer sample.”. This substitutes a different outcome for the one that was measured or reported. Compare the alternative “It would make the timing of a loud peak impossible to record.”. This substitutes a different outcome for the one that was measured or reported.

What a small set of sensors can tell us

What does the report recommend before selecting a general time ban?

  1. Selecting the ban first and then testing which routes comply with it.
  2. Agreeing a preferred conclusion with campaigners before gathering more readings.
  3. Removing the side-street recordings so the sample is more consistent.
  4. Discussion of delivery routes and loading practices.
Answer & explanation
Discussion of delivery routes and loading practices.

The supported answer is “Discussion of delivery routes and loading practices.”. Evidence: “Our report recommends discussing changes to delivery routes and loading practices before choosing a general time ban.”. Compare the alternative “Selecting the ban first and then testing which routes comply with it.”. This recommends acting before the further evidence or safeguards requested in the passage are available. Compare the alternative “Removing the side-street recordings so the sample is more consistent.”. This reverses the relationship stated in the passage.

X02 · Text challenge

What a small set of sensors can tell us

What is the planned next step?

  1. Republishing the daily average without collecting another set of measurements.
  2. Test quieter loading at two businesses and measure again.
  3. Introducing the full evening ban before the loading trial begins.
  4. Interviewing residents instead of measuring the effect of quieter loading.
Answer & explanation
Test quieter loading at two businesses and measure again.

The supported answer is “Test quieter loading at two businesses and measure again.”. Evidence: “The next stage is a trial of quieter loading at two businesses, followed by another round of measurements.”. Compare the alternative “Republishing the daily average without collecting another set of measurements.”. This reverses the relationship stated in the passage. Compare the alternative “Introducing the full evening ban before the loading trial begins.”. This confuses two stages of the account: the initial situation and a later check or decision.
