Questions & answers

Opening an answer records help for that question.

D01 · Warm-up

The value and limits of public ratings

What did the speaker previously overlook about an average rating?

  1. Whether an online numerical rating was available.
  2. Whether the cafe’s displayed average was high.
  3. The number of reviews behind it.
  4. The precise decimal value displayed as the cafe’s average.
Answer & explanation
The number of reviews behind it.

The supported answer is “The number of reviews behind it.”. Evidence: “whether that average came from twelve reviews or twelve hundred”. Compare the alternative “The precise decimal value displayed as the cafe’s average.”. This was information the speaker already noticed or used. The question asks what was not checked behind the average. Check the source wording “A four-point-eight looked reassuringly precise.” against the question and the claim “The precise decimal value displayed as the cafe’s average.”. Compare the alternative “Whether the cafe’s displayed average was high.”. This was information the speaker already noticed or used. The question asks what was not checked behind the average. Check the source wording “A four-point-eight looked reassuringly precise.” against the question and the claim “Whether the cafe’s displayed average was high.”.

D02 · Warm-up

The value and limits of public ratings

Why might two sincere reviewers rate the same cafe differently?

  1. A difference in their scores means at least one account is insincere.
  2. The displayed average creates the preferences behind the individual ratings.
  3. Sincere reviewers must have visited under identical circumstances.
  4. They may want different kinds of visit.
Answer & explanation
They may want different kinds of visit.

The supported answer is “They may want different kinds of visit.”. Evidence: “Someone looking for a quiet place to read may judge a lively cafe very differently from a group celebrating a birthday.”. Compare the alternative “A difference in their scores means at least one account is insincere.”. This turns an observed association into a causal conclusion that the account does not establish. Compare the alternative “The displayed average creates the preferences behind the individual ratings.”. This reverses the relationship stated in the passage.

P01 · Build the skill

The value and limits of public ratings

What can be useful according to the speaker?

  1. An older review simply because it has remained online longest.
  2. A forceful complaint treated as typical without looking for repetition.
  3. A repeated, specific complaint.
  4. A small score advantage without checking what produced the average.
Answer & explanation
A repeated, specific complaint.

The supported answer is “A repeated, specific complaint.”. Evidence: “A repeated, specific complaint can alert us to a problem worth investigating.”. Compare the alternative “A small score advantage without checking what produced the average.”. This makes one indicator sufficient on its own, although the passage calls for a broader assessment. Compare the alternative “An older review simply because it has remained online longest.”. This replaces the stated basis for judging a decision with a different criterion.

P02 · Build the skill

The value and limits of public ratings

What role should a rating play?

  1. A way of deciding which cafe meets personal needs without further judgement.
  2. Evidence that the reviewers’ preferences match those of the listener.
  3. A starting point for a decision.
  4. A reliable forecast of how satisfied any future visitor will be.
Answer & explanation
A starting point for a decision.

The supported answer is “A starting point for a decision.”. Evidence: “the beginning of a decision, rather than the end.”. Compare the alternative “A way of deciding which cafe meets personal needs without further judgement.”. This makes one indicator sufficient on its own, although the passage calls for a broader assessment. Compare the alternative “Evidence that the reviewers’ preferences match those of the listener.”. This extends a qualified finding into a claim without exceptions.

The value and limits of public ratings

Why might available reviews be unrepresentative?

  1. Each ordinary experience is represented by a balanced mix of extreme reviews.
  2. The comments include an automatic account from each person who visited.
  3. A selection problem means positive comments should be presumed dishonest.
  4. People with ordinary experiences may not write reviews.
Answer & explanation
People with ordinary experiences may not write reviews.

The supported answer is “People with ordinary experiences may not write reviews.”. Evidence: “People with an ordinary, acceptable experience may have less reason to write anything at all.”. Compare the alternative “The comments include an automatic account from each person who visited.”. This extends a qualified finding into a claim without exceptions. Compare the alternative “A selection problem means positive comments should be presumed dishonest.”. This reduces the argument to two opposing alternatives that the speaker or writer explicitly rejects.

X01 · Text challenge

The value and limits of public ratings

Which design change would the speaker support?

  1. Showing the distribution and recency of ratings.
  2. Using the total number of reviews without distinguishing recent ones.
  3. Presenting the overall average more prominently than the variation behind it.
  4. Replacing descriptive accounts with a single score to reduce disagreement.
Answer & explanation
Showing the distribution and recency of ratings.

The supported answer is “Showing the distribution and recency of ratings.”. Evidence: “show how many reviews are recent, make the spread of ratings visible”. Compare the alternative “Presenting the overall average more prominently than the variation behind it.”. This makes one indicator sufficient on its own, although the passage calls for a broader assessment. Compare the alternative “Using the total number of reviews without distinguishing recent ones.”. This reverses the relationship stated in the passage.
