Civic Evidence, Claims & Fair Public Reasoning — Practice · Grade 12 Social Studies

Chapter: Foundations of Government & Public Reasoning

What this practice covers

By the end of Civic Evidence, Claims & Fair Public Reasoning you should be able to:

8 questions, written answer, each with a worked explanation.

Vocabulary used: empirical claim, normative claim, provenance, corroboration, causal mechanism.

Problem 1

Why does a policy preference need different support from a factual statement?
Answer and explanation

A factual statement needs evidence establishing what occurred. A preference also needs an explained criterion for weighing options and consequences. Relevant facts inform the judgment, but they do not automatically determine how every person should rank competing values.

Problem 2

Why do repeated posts not necessarily corroborate a claim?
Answer and explanation

They may all depend on one unverified source. Independent corroboration requires evidence with a separate origin relevant to the same claim. Trace the original record and compare date, method, and scope rather than using circulation as a substitute for verification.

Problem 3

What is missing from a claim that a policy caused an improvement because it came first?
Answer and explanation

The sequence does not isolate the mechanism or rule out other changes. Examine comparable measurements, plausible pathways, and alternative explanations. Chronology can support inquiry but cannot alone establish the policy’s contribution.

Problem 4

What makes a limitation useful to a decision-maker?
Answer and explanation

It identifies a specific missing measure, assumption, scope restriction, or uncertainty and explains why it matters. It also suggests evidence that could test the claim. A generic statement that no one can know anything does not provide that guidance.

Problem 5

Invented packet: reported crashes fell from 20 to 12 after new signs; the road was also rebuilt; vehicle trips fell; one publicity post calls the signs the sole cause. Evaluate the claim using the supplied evidence.
Answer and explanation

Reported crashes fell by eight, or 40 percent of the original 20. The packet establishes a decline in counts, not the signs’ isolated effect or a crash rate per trip. Reconstruction and traffic changes are alternative influences. A useful next comparison would use consistent reporting, trip counts, timing, and comparable roads. It is reasonable to investigate whether the signs contributed, but the sole-cause assertion exceeds the supplied evidence.

Calculate the change in reported crashes.

Identify simultaneous changes and missing exposure data.

State a bounded conclusion and further evidence need.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 6

Can two well-supported policy judgments disagree?
Answer and explanation

Yes. People can use accurate evidence yet weigh cost, access, rights, or uncertainty differently. Strong work states the criterion, compares alternatives, and addresses counterevidence. Different priorities do not excuse factual errors or fabricated testimony.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 7

Invented town complaints fall from 50 to 40 after a new online form, but reporting access also changes. Calculate the count decline and qualify the success claim.
Answer and explanation

The count falls by ten, or twenty percent. Changed reporting access may affect the observed count, so it does not alone prove underlying problems decreased. Compare consistent reporting, access, outcomes, and other changes before attributing success to the form.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 8

Five articles all quote one anonymous screenshot. How would you strengthen the evidence record?
Answer and explanation

Trace the underlying document, creator, date, context, and method. Seek relevant independently produced records rather than counting repetitions. State uncertainty if the origin cannot be verified; circulation is not corroboration.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
