Difficulty: Easy
Correct Answer: None is implicit
Explanation:
Introduction / Context:The statement is an observation contrasting heavy rainfall with uninterrupted traffic. We examine which assumptions must underlie this observation.
Given Data / Assumptions:
Concept / Approach:An assumption is required only if the statement would be unreasonable without it. The sentence merely reports a fact for “this year.” It does not claim causes or exclusivity.
Step-by-Step Solution:
1) I is not required. The statement says nothing about other seasons; disruption can happen in many conditions.2) II contradicts the phrasing “in spite of heavy rains,” which implies rains typically hinder traffic. So II is not assumed.3) III suggests a reason (precautions), but the statement does not assert any causal explanation. Thus III is not necessary.Verification / Alternative check:Even if there were no special precautions, it is still possible that traffic was not disrupted this year. Hence none of the three is indispensable.
Why Other Options Are Wrong:
Common Pitfalls:Reading implied causes (“precautions”) into a bare observation, or treating one year’s outcome as a universal rule.
Final Answer:None is implicit
