Distinguishing "False" from "Can't Tell" — The Hardest Skill

The boundary between False and Can't Tell is where most UCAT VR marks are lost. This practice set targets this distinction directly. Every question in this set is designed to test whether you can tell the difference between a passage that contradicts a statement (False) and a passage that simply does not address a statement (Can't Tell).

Quick-Reference Strategy

1. Read the statement. What exactly is it claiming?
2. Search the passage. Can you find information that directly addresses this claim?
3. Apply the key test: Does the passage actively contradict the statement, or is it merely silent?

Finding	Answer
The passage says the opposite or something logically incompatible	False
The passage does not mention the topic or does not provide enough detail	Can't Tell

Focus Notes

The "Silence vs Contradiction" Test

This is the single most important skill for the False/Can't Tell boundary:

• Contradiction = the passage provides information that is incompatible with the statement. Example: passage says "open Monday to Friday," statement says "open on Saturdays" → False.
• Silence = the passage simply does not address the topic. Example: passage discusses a London hospital, statement says "hospitals in Manchester achieved similar results" → Can't Tell.

When Absence of Mention Feels Like "False"

Many candidates fall into the trap of thinking: "The passage does not mention X, therefore X is not true, therefore the answer is False." This is wrong. Absence of evidence is not evidence of absence. If the passage does not discuss X, you cannot conclude anything about X.

When "False" Is Disguised as Ambiguity

Sometimes the passage does contradict the statement, but the contradiction is subtle. Look for:

• Quantifier mismatches — passage says "most"; statement says "all"
• Scope conflicts — passage says "in England"; statement says "in Europe"
• Temporal contradictions — passage says "since 2020"; statement says "has always been the case"
• Implied exclusions — passage says "open Monday to Friday" implies not open on weekends

Approach Each Question

Each question presents a passage and a statement designed to sit on the False/Can't Tell boundary. Your job is to determine which side it falls on. Ask yourself: does the passage contradict this, or is it simply silent?
