Analysing Arguments

(a) Main conclusion: "Governments should subsidise electric cars" (signposted by 'therefore') — a policy claim.

(b) One reason: "cleaner air means fewer respiratory illnesses" (also acceptable: "electric cars produce no exhaust emissions").

(c) Intermediate conclusion: "cities that adopt them will have cleaner air" — it is the conclusion of the first step and a reason in the larger argument.

(d) Unstated assumption + type: that the electricity used to charge the cars is itself generated cleanly (if it comes from coal, the "cleaner air" step fails). This is a cause–effect / hidden-condition assumption.

(a) Conclusion: "Zoos should be abolished" — a policy claim.

(b) Two reasons: (i) zoos confine wild animals in unnatural conditions; (ii) most zoos do little genuine conservation.

(c) Assertion: "Everyone knows animals belong in the wild" — a claim stated without support (an appeal to popularity, signalled by "everyone knows").

(d) Reason or conclusion: a reason — it answers "why abolish zoos?" and so supports the conclusion.

Deconstruction. The conclusion (signposted by "therefore") is the value/policy claim that "it is wrong to demand developing countries cut emissions." It is supported by three reasons — every wealthy nation industrialised with fossil fuels (historical), renewables are too expensive for poorer economies (economic), and denying cheap energy would trap millions in poverty (consequence) — chaining to an intermediate conclusion that developing countries need cheap fossil energy.

Evaluating the evidence (R-R-S). The argument offers almost no concrete evidence.

• Relevance: the historical point ("every wealthy nation") is relevant to fairness but not to whether a fossil path is still necessary today.
• Reliability: "every wealthy nation" is a sweeping generalisation, and "renewables are too expensive" is asserted with no figures and may be out of date given falling renewable costs.
• Sufficiency: there is not enough evidence to establish the key economic claim; it rests on assertion.

Evaluating the reasoning. The fairness/hypocrisy point has genuine force, but the argument over-reaches and contains flaws: a false dilemma (cheap fossil fuels or poverty) that ignores cleaner alternatives, and an unstated assumption that there is no affordable clean path — negate it and the conclusion collapses. It also assumes that historical precedent creates a present entitlement, and ignores that climate change harms developing nations themselves.

Judgement and A* finish. The argument is partly persuasive but weak as it stands: its moral point is real, but it is under-evidenced and rests on a false dilemma. To be convincing it would need current cost data on renewables in developing economies, evidence that a fossil path is genuinely the only affordable route, and an account that weighs the climate damage these nations face against the benefit of cheap energy.

Deconstruction. The conclusion is the strong policy claim "we must close the borders completely." Its apparent support, however, is a series of assertions rather than evidenced reasons: "it is obvious", "everyone can see our country is full", "real patriots know… open borders are dangerous", and "only the naive disagree."

Evaluating the evidence (R-R-S). There is, in effect, no evidence at all.

• Relevance / reliability: "full" is undefined and unmeasured; "open borders are dangerous" is asserted with no data.
• Sufficiency: with no evidence presented, the support is wholly insufficient for so absolute a conclusion ("completely").

Evaluating the reasoning. The argument relies on fallacies and rhetoric: an appeal to popularity ("everyone can see"), an appeal to patriotism and loaded language ("real patriots"), and an ad hominem that dismisses opponents as "naive" instead of answering the counter-assertion that immigration may be beneficial or manageable. It rests on unstated assumptions — that the country genuinely cannot accommodate more people, and that immigration is uniformly harmful — neither of which is supported.

Judgement and A* finish. This is a very weak argument: it is persuasion by assertion, popularity and insult, not reasoning. To carry any weight it would need actual evidence — data on housing, services and capacity to show the country is "full", and balanced evidence of immigration's real effects (both costs and benefits) — and it would need to address, rather than dismiss, the opposing case.

Introduction and thesis. Both sources address how developing countries should industrialise, reaching opposite conclusions — A defends a cheap fossil-fuel path, B argues for leapfrogging to renewables. This answer argues that Source B is the more convincing case, although A's fairness point is genuine.

Comparing the evidence. A's central figure — "a single plant adds a negligible 0.1%" — is statistical, but it commits a fallacy of composition: what is negligible individually is decisive when many nations reason the same way, so its relevance to the global question is weak. A's claim that renewables are "too expensive and unreliable" is asserted without data. B, by contrast, cites an IEA projection that solar will be the cheapest power source — more credible and directly relevant to A's cost claim — though, as a projection, it is forward-looking and uncertain. On balance B's evidence engages A's strongest premise (cost) more directly.

Comparing the reasoning and assumptions. Both lean on analogies: A on "the West did it" (historical fairness) and B on "leapfrogging like mobile phones." A's analogy supports a right but not a necessity today; B's analogy is apt only if clean technology genuinely transfers — an assumption B itself relies on. A's argument also rests on a false dilemma (cheap fossil fuels or poverty) and the assumption that there is no affordable clean path — precisely the assumption B attacks with its cost projection. B assumes renewables will scale reliably, which is not yet proven.

Comparing perspectives and criteria. The sources apply different criteria: A judges by present poverty reduction and historical justice, B by long-term sustainability and the developing nations' own vulnerability. Importantly, they partly converge — B does not dismiss development, but claims a cleaner route to the same goal — which weakens A's framing of the choice as growth versus environment.

Reasoned judgement. Source B is more convincing. It answers A's strongest point (the need for affordable development) with evidence of a cleaner alternative, avoids A's fallacy of composition and false dilemma, and notes that developing nations are themselves harmed by the very emissions A would increase. A's fairness/hypocrisy point is genuine and a complete policy must take it seriously — and B's case depends on an optimistic assumption about renewables scaling. But as the two arguments stand, B's reasoning is sounder and its evidence more relevant. Had A shown with current data that no affordable clean path exists, the balance could shift; it does not.

Introduction and thesis. Both sources respond to automation but reach opposite conclusions — A demands a universal basic income (UBI), B rejects it in favour of retraining. This answer argues that neither is conclusive, but that Source B reasons slightly more soundly, while A raises a risk B underplays.

Comparing the evidence. Strikingly, both sources offer little hard evidence. A asserts that machines are "cheaper" and that unemployment is "inevitable" but provides no data on net job loss. B offers a historical analogy (cars and the horse trade) as evidence that technology creates more jobs than it destroys. On relevance and sufficiency, B's analogy is at least a concrete precedent, whereas A's "inevitable" is an unsupported prediction — but a single historical analogy is insufficient to prove this automation wave will behave like past ones.

Comparing the reasoning and assumptions. A's argument rests on the key assumption that automation will not create enough new jobs to replace those lost (negate it and the case for UBI weakens) and escalates into a slippery slope ("before society collapses"). B rests on the assumption that the historical pattern will repeat — a possibly faulty analogy if AI-driven automation differs from previous waves — and on the assertion, again unevidenced, that UBI "discourages work."

Comparing perspectives and criteria. A argues from a precautionary, social-safety perspective (protect people from a predicted shock); B from a fiscal-responsibility and work-incentive perspective (affordability and effort). They prioritise different values — security against disruption versus economic prudence and self-reliance.

Reasoned judgement. On balance, Source B is marginally more convincing in its reasoning, because it offers a concrete precedent rather than mere assertion and avoids A's slippery-slope language; however, its analogy may not hold for a uniquely capable wave of automation, and it dismisses UBI without evidence. A performs a service in flagging a genuine risk — that this time may be different — but undermines itself with an unsupported "inevitable" and catastrophising. Because both rest on contested assumptions and thin evidence, the most defensible verdict is provisional: B's case is currently better grounded, but the question turns on evidence neither source provides — namely, reliable data on whether automation is now destroying jobs faster than it creates them.
