Warm-up · 5 min

Turn the baseline seam into a reading question

Retrieval · Lesson 1 baseline

Place the untouched Porto Claro statement, audio and listener map beside the secure chain and local seam saved in Lesson 1.

Write one question that authentic formal argument can help you investigate.

  • Copy one exact baseline sentence and its listener response without improving either.
  • Classify the seam as position, warrant, counterargument, evidence limit, emphasis, payoff, prosody or responsibility.
  • Complete: “How does an experienced public writer make ___ prominent while still acknowledging ___?”
  • Keep the question open. Lesson 3 will establish the negative and conditional inversion system.
Authentic-input stance

Choose the reading question that connects marked language to a complete argument.

1. What should you ask when a formal writer gives one proposition unusual prominence?

Input & Noticing · 18 min

Two arguments for transparency with different limits

Source A · Formal public-policy report

Centre for Data Ethics and Innovation, Review into bias in algorithmic decision-making, 27 November 2020. Read Chapter 9 from “Why the public sector?” through “What is the value of transparency?”, then Recommendation 16 and “What is in scope?”. The short turn Yet the term ‘transparency’ can be ambiguous signals that the report will qualify the principle before specifying an obligation.

Source B · Public-policy commentary

Diane Coyle, “The tensions between explainable AI and good public policy”, Brookings, 15 September 2020. Read from the paragraph beginning “A common principle of AI ethics” through the conclusion beginning “The first step”. The compact claim Yet explainability alone will not be a panacea concedes its democratic value before challenging its sufficiency.

Teacher note Use the linked originals and retain their genres and dates. Source A is a UK public-body review that makes recommendations after examining public-sector accountability; Source B is an authored commentary that argues explainability cannot resolve conflicts among policy objectives or substitute for trustworthy institutions. Neither source reports on fictional Porto Claro. If access fails, use the verified maps below for meaning work and mark detailed wording, layout and source-location observations unavailable rather than inventing them.

Verified source maps · Confirm each move in the original

Argument layerSource A · CDEI reviewSource B · Coyle commentary
Opening warrantPublic bodies make high-impact decisions, owe citizens special accountability and cannot be avoided like a commercial serviceExplainability is essential to democracy as public agencies increasingly use consequential automated systems
ComplicationTransparency is ambiguous and can enable gaming, expose intellectual property or supply unusable informationModel explanation can conflict with performance and cannot settle political disagreement about the objective a system should optimize
Counterargument treatmentThe report accepts innovation and efficiency as public responsibilities, then conditions them on risk control, evidence and accountabilityThe commentary accepts that explicit objectives may expose useful trade-offs, then argues that this exposure remains politically difficult
Controlling distinctionMore information is separated from effective information that is accessible, intelligible, usable and assessableTechnical explainability is separated from institutional trustworthiness and explicit public aims
Proposed responseA scoped mandatory transparency obligation, piloted for algorithms with significant influence on significant decisionsRestore trustworthy institutions and confront policy objectives rather than expecting explainability to resolve political conflict
Boundary for Porto ClaroThe report offers a reasoning lens and comparator, not evidence that the city’s draft has the right scope or resourcesThe commentary supplies a challenge to sufficiency, not evidence that the fictional charter should be rejected
Source comparison

Match each observation to Source A, Source B or both. Confirm it in the assigned source location before answering.

A CDEI review

B Coyle commentary

Both Both sources

1. Treats transparency or explainability as valuable but insufficient on its own.

2. Turns a qualified case into a specific recommendation for a mandatory, scoped obligation.

3. Makes conflicting public objectives central to the limits of a technical solution.

4. Uses concession to preserve a serious competing value before advancing the main claim.

5. Distinguishes intelligible and usable disclosure from publication for its own sake.

6. Ends by placing institutional trustworthiness before reliance on automated decision-making.

7. Can inform argument design for Porto Claro but cannot establish a fact about its fictional record.

Claim fidelity

Choose the paraphrase that preserves the source’s argumentative scope.

1. Which statement best represents Source A?

2. Which statement best represents Source B?

3. How do the sources relate?

03
Focus on Form · 7 min

Notice the rhetorical hinge before naming the grammar

Authentic moves · Full inversion forms follow in Lesson 3

MoveSource locationPressure and payoff
Concede, then restrictSource B: the transition from explainability as a democratic principle to the “panacea” claimThe concession protects common ground; the marked turn makes the insufficiency claim prominent
Name a principle, then test itSource A: “What is the value of transparency?”The report moves from an attractive abstraction to gaming, intelligibility and trust tests
Pair gains across domainsSource A: the Cyber Essentials example under “Why the public sector?”The paired construction promises a second beneficiary and completes that promise; its position here does not trigger subject–auxiliary inversion
Escalate from mechanism to objectiveSource B: the numbered reasons and the transition to conflicting policy aimsThe second problem is framed as deeper because explanation cannot choose among legitimate goals
Convert principle into scopeSource A: Recommendation 16 followed by “What is in scope?”The recommendation gains force, then the significance definitions constrain its reach
Hinge → discourse job

Match each authentic or closely paraphrased hinge to its job in the complete argument. Do not transform it into inversion yet.

Restricts a valued principle after conceding its importance
Makes the coming objection sequence visible to the reader
Returns from the innovation case to non-negotiable conditions
Creates and fulfils a paired rhetorical expectation
Limits implementation after a forceful recommendation
Markedness before rule

Choose the analysis supported by the source context.

1. Why is Source B’s early “Yet” effective?

2. What does Source A’s paired “not only … but also …” example show?

3. What should be carried into Lesson 3?

04
Guided Practice · 8 min

Reconstruct the argument, then borrow the move

Concession-to-scope chain

Order this synthesis of Source A’s reasoning. Then mark the sentence that creates the strongest pressure for a later formal emphasis choice.

  1. That standard supports a proactive obligation where an algorithm significantly influences a significant decision.
  2. Public bodies owe citizens a special account of consequential decisions that residents cannot simply avoid.
  3. A pilot and precise definitions must still determine how the obligation works in practice.
  4. Transparency can nevertheless be ambiguous, unusable or open to gaming when treated as publication for its own sake.
  5. The relevant standard is therefore effective disclosure that people can find, understand, use and assess.

Move ledger · Pair or solo

Choose one hinge from each source and one unresolved seam from the Lesson 1 baseline.

Plan a two-sentence Porto Claro revision that borrows the argumentative relationship without borrowing the source’s conclusion.

  • Record the original source, exact section or paragraph opening, move, expectation and payoff in your own words.
  • Name the Porto Claro evidence and public criterion that could earn a comparable move.
  • Draft in plain clauses first. Keep the source as a communication model, not evidence about the fictional city.
  • Leave one marked alternative in notes for Lesson 3 rather than guessing at the full inversion rule.
05
Main Task · 14 min

Write a council reading memo that keeps the records separate

Source synthesis · 180–220 words

The Porto Claro council chair asks what the two published arguments should make the committee test before it debates the fictional charter again.

Write a 180–220-word reading memo that accurately synthesizes both sources, transfers two reasoning moves and leaves the Porto Claro decision open to its own evidence.

  • Minutes 1–3 · retrieve: write one sentence for each source’s main claim, strongest concession and proposed response. Add an exact section or paragraph anchor.
  • Minutes 4–8 · synthesize: explain one point of convergence and one difference in mechanism or scope. Use at least one concession-to-claim chain and one explicit payoff.
  • Minutes 9–11 · apply: name two questions the council should test against its dossier—for example significance, usable disclosure, conflicting objectives, institutional capacity or remedy.
  • Minutes 12–13 · protect boundaries: underline every sentence about Porto Claro and confirm that it relies only on the fictional dossier or is framed as a question, criterion or analogy.
  • Minute 14 · read aloud: mark thought groups and prominence on concession, controlling distinction and payoff. Record once and save the memo with the Lesson 1 baseline.

Reading-memo evidence record

DimensionObservable evidence
Source fidelityEach writer’s claim, concession, response and boundary remain distinguishable
SynthesisConvergence and difference are related rather than listed as two summaries
TransferSource moves generate Porto Claro questions or criteria without becoming fictional case facts
Rhetorical payoffA marked hinge creates an expectation that the following reasoning fulfils
ScopeSignificance, sufficiency, implementation and institutional claims retain their limits
ProsodyThought groups and prominence make the concession and controlling claim recoverable
Teacher note Accept different evaluations of the sources when the memo represents each argument accurately and cites the assigned location. Do not require inversion in this lesson. If a learner produces it spontaneously, preserve the exact form and listener effect for Lesson 3; assess the present task on source fidelity, synthesis, evidence boundaries and rhetorical payoff. Treat any Brazilian-Portuguese comparison as a hypothesis only when repeated comparable learner evidence predicts an English listener effect.
06
Feedback & Reflection · 5 min

Check what the emphasis actually earned

Source-bound revision

Choose the feedback that best preserves argument quality and source status.

1. The memo says “Coyle proves Porto Claro’s charter cannot work.” What needs repair first?

2. The memo announces a second benefit but moves immediately to a new objection. What is the local problem?

3. The reader understands both summaries but cannot state how the sources differ. What revision has highest value?

One hinge, one payoff

Exchange the memo with a reader or replay it after a short delay and mark the most prominent hinge.

Revise one sentence pair so the common ground, turn and payoff are all recoverable.

  • Keep the original and revised pair. Label source-derived move, Porto Claro evidence boundary and listener response separately.
  • Do not add a marked structure unless the argument already earns its contrast, exception, pair or condition.
07
Wrap-up & Bridge · 3 min

Carry rhetorical pressure into the form system

Exit principle

Choose the evidence Lesson 3 should explain.

1. What should guide the first systematic choice between a plain clause and inversion?

Standing informal-input bridge

Continue the selected full Intelligence Squared debate and high-quality op-ed. Save exact time stamps or paragraph locations for one concession, one restrictive or exceptional claim, one paired claim, one condition and the payoff that follows each. Record plain as well as marked realizations; the point is to arrive in Lesson 3 with authentic argument pressures, not a decontextualized inversion hunt.
