$\frac{b}{3}$✔️
$\frac{2b}{3}$

Quantitative Reasoning QUESTION #8131

Question 10

Recent improvements in mountain-climbing equipment have made the sport both safer and more enjoyable for experienced climbers. Yet despite these advances, the rate of mountain-climbing injuries has doubled over the same period. Which of the following, if true, best resolves this apparent contradiction?

Many climbers feel a false sense of security and attempt feats beyond their skill level using the new equipment.✔️
Some mountain-climbing injuries result from unforeseeable weather conditions.
Mountain climbing does not normally result in injury to the experienced climber.
Improvements in technique have also occurred alongside equipment advances.

Correct Answer Logic:

The paradox: better equipment → more injuries. Option A resolves it perfectly: better equipment makes inexperienced climbers overconfident, leading them to attempt climbs beyond their ability, causing more injuries. This explains why injuries rose even though the equipment improved. Option B doesn't explain the doubling trend. Option C is irrelevant (it's about experienced climbers). Option D deepens, not resolves, the paradox.

Its stated objectives were to support Pakistan's democratic governance, civilian institutions, and socioeconomic development — with specific focus on energy infrastructure (to address the power crisis), education (school construction and teacher training), and economic growth.

Singular 'phenomenon' correctly pairs with singular verb 'is.' 'Many of them children' is a proper absolute phrase describing the beggars. Option A uses plural 'phenomena' with singular 'is' (subject-verb disagreement). Option B is structurally awkward. Option D creates disagreement between 'a wave…are.'
