🎯 What you'll practice: The TRUE/FALSE/NOT GIVEN process and the traps that cause the most errors.
1-B 2-B 3-B 4-B | 5 = FALSE 6 = NOT GIVEN 7 = read the statement, scan for key words, read that section carefully, compare meaning 8 = e.g. passage mentions "some studies show a decline" but the question claims a specific percentage — the number isn't given 9 = because it requires a strict distinction between "contradicted" and "simply absent," and test-takers naturally want to use logic or outside knowledge to fill gaps the text leaves open, which is exactly the wrong instinct here | 10 = "Several" only confirms that more than one city studied the issue — it makes no claim about ALL cities, so the statement "every city" goes beyond what the passage actually says; this is a case of an unsupported generalisation, not a direct contradiction, which is precisely why it's NOT GIVEN rather than FALSE — FALSE would require the passage to actively state that not every city studied it.
