Assessing Additional Evidence
Judge whether new information strengthens, weakens or leaves unchanged the exact route from reasons to conclusion.
How to prepare for the TARA
Learn the official question types, practise five-option reasoning without a calculator, and rehearse one 40-minute writing process that explains, counters and judges a proposition.
Core concepts
Concept 1
Evidence matters through its effect on the argument's stated conclusion and supporting link.
Exam cue: Identify the conclusion and vulnerable support link first.
Concept 2
New information may be relevant to the topic without strengthening or weakening the argument.
Exam cue: State the direction and mechanism of each option's effect.
Concept 3
Evidence can affect a premise, an assumption, an alternative explanation or the conclusion's scope.
Exam cue: Reject information that changes a nearby issue but not the argument.
Risk pitfalls and guardrails
Equating topical relevance with argumentative impact.
Guardrail: Do not import subject detail the task does not require or confuse a plausible result with one established by the supplied reasoning.
Choosing evidence that supports a different conclusion.
Guardrail: Do not import subject detail the task does not require or confuse a plausible result with one established by the supplied reasoning.
Failing to notice that an option weakens the reliability of the original evidence.
Guardrail: Do not import subject detail the task does not require or confuse a plausible result with one established by the supplied reasoning.
Memory anchors
Target the Conclusion
Measure evidence against the argument actually made.
Mechanism
Explain how the new fact changes a reason, assumption or alternative.
Strengthen
New evidence makes the conclusion better supported.
Weaken
New evidence damages support or supplies a credible alternative.
No Effect
Related information may leave the inferential link unchanged.
Direction Check
Do not choose weakening evidence when the stem asks for strengthening.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
