Q21The chambers handled more arbitration work than High Court litigation work during this period.
✓ Correct answer: C. Insufficient Data
We know arbitration rose 35% and litigation fell 12%, but we have no baseline figures. Arbitration could still be smaller in absolute terms.
Topic: Inference
Q22Clients increasingly prefer arbitration to High Court litigation for commercial disputes.
✓ Correct answer: B. Probably True
The trend at this chambers and the head's stated reason support this as probably true, though it is one chambers' data and cannot be generalised with certainty.
Topic: Inference
Q23Confidentiality is not available in High Court litigation.
✓ Correct answer: C. Insufficient Data
The passage says clients prefer arbitration partly for confidentiality, but does not state that confidentiality is unavailable in High Court proceedings. Some hearings can be held in private.
Topic: Inference
Q24The chambers' total fee income from dispute resolution increased over the period.
✓ Correct answer: C. Insufficient Data
Arbitration rose but litigation fell; without knowing fee rates for each or the initial volumes, we cannot determine net income change.
Topic: Inference
Q25High Court litigation instructions at this chambers fell during the 12-month period.
✓ Correct answer: A. True
The passage explicitly states instructions for High Court litigation fell by 12%.
Topic: Inference
Q26A hospital recorded that 78% of patients admitted for heart surgery were over the age of 60. The remaining patients were younger adults between 18 and 59. No patients under 18 were admitted for heart surgery during this period. Proposed inference: 'More than three-quarters of heart surgery patients at this hospital were senior citizens.' — How true is this inference?
✓ Correct answer: A. True
The passage directly states 78% of heart surgery patients were over 60. Since 78% exceeds three-quarters (75%), this is directly confirmed by the passage — True.
Topic: Inference
Q27A city's public library system reported a 35% increase in digital book downloads over the past year. Meanwhile, physical book loans decreased by 12% in the same period. The director attributed the shift to a new e-reader lending program launched 14 months ago. Proposed inference: 'Readers are gradually preferring digital formats over physical books.' — How true is this inference?
✓ Correct answer: B. Probably True
Rising digital downloads alongside falling physical loans strongly suggests a preference shift. However, other factors (e-reader program novelty, specific demographics) mean certainty is not possible — Probably True.
Topic: Inference
Q28A pharmaceutical company conducted a clinical trial in which 500 patients with chronic migraines received a new drug. After 8 weeks, 61% reported a significant reduction in migraine frequency. The trial did not include a placebo control group. Proposed inference: 'The drug is more effective than a placebo at reducing migraine frequency.' — How true is this inference?
✓ Correct answer: D. Insufficient Data
Without a placebo control group, it is impossible to determine whether the drug outperforms placebo. The passage explicitly notes no placebo group was used, so this comparison cannot be made — Insufficient Data.
Topic: Inference
Q29A study of 1,200 university students found that those sleeping fewer than 6 hours per night had an average GPA of 2.8, while those sleeping 7–9 hours averaged 3.4. The study controlled for major, year of study, and part-time employment status. Proposed inference: 'Students who sleep less perform worse academically than those who sleep more.' — How true is this inference?
✓ Correct answer: B. Probably True
The controlled study shows a substantial GPA difference by sleep duration. However, reverse causation (academic stress causing sleep deprivation) means certainty is not justified — Probably True.
Topic: Inference
Q30A survey of 400 small business owners found that 82% used social media for marketing. Of those, 67% reported social media was their most cost-effective channel. The survey was conducted online with self-selected respondents. Proposed inference: 'The majority of all small businesses nationwide find social media to be their most cost-effective marketing channel.' — How true is this inference?
✓ Correct answer: D. Insufficient Data
Self-selection bias and a small, non-representative sample prevent generalization to all small businesses nationally — Insufficient Data to support the inference.
