Correct Answer: All participants in the race are students
Explanation:
Introduction / Context:This verbal-reasoning item is a classic syllogism. We are given three set relationships about students, participants, and girls invited for coaching. The task is to deduce what must be true in all models that satisfy the premises.
Given Data / Assumptions:
Concept / Approach:Translate each sentence into a set inclusion. Focus first on what is asserted universally (I and III) before interpreting the existential information (II). The safest conclusion is one that follows from universal containment and does not overreach.
Step-by-Step Solution:
1) From I, every participant is necessarily a student. This alone yields “All participants in the race are students.”2) II simply guarantees at least one girl participant; with III, those girl participants are invited, but this does not make all participants invited.3) There is no premise asserting that all students (or all participants) are invited—only girl participants are guaranteed invited.Verification / Alternative check:Construct a Venn model with Participants entirely inside Students. Place some participants in the overlap with Girls to be Invited. Non-girl participants need not be invited. The statement “All participants are students” holds in every such model.
Why Other Options Are Wrong:
• (a) Overgeneralises invitation from “girl participants” to all participants.• (b) Extends invitation to all students without support.• (d)/(e) contradict set relations or add unsupported restrictions.Common Pitfalls:Confusing “only if” style constraints and assuming converses; promoting existential facts (“some”) to universals (“all”).
Final Answer:All participants in the race are students.
