Every one of the students who participated / in the national science fair / has brought their own equipment. / No error
आपने शायद यह सोचाWhat you probably thoughtपहला segment अशुद्ध प्रतीत हुआ क्योंकि 'students' बहुवचन है और उसके बाद 'who participated' आता है। परंतु 'who' बहुवचन 'students' के लिए है और 'participated' भूतकाल रूप है, अतः यह शुद्ध है।The first segment seemed wrong because 'students' is plural but 'who participated' follows. But 'who' refers to the plural 'students' and 'participated' is a past form, so it is correct.
आपने शायद यह सोचाWhat you probably thoughtदूसरा segment अशुद्ध प्रतीत हुआ क्योंकि fair के लिए 'at' जैसा preposition (पूर्वसर्ग) भी चलता है। परंतु किसी आयोजन में भाग लेने के लिए 'in the national science fair' शुद्ध phrase है।The second segment seemed wrong because a preposition like 'at' also fits a fair. But 'in the national science fair' is a correct phrase for taking part in an event.
आपने शायद यह सोचाWhat you probably thought'No error' ठीक प्रतीत हुआ क्योंकि अनेक लोग अज्ञात लिंग के व्यक्ति के लिए 'their' बोलते हैं। परंतु परीक्षा के Concept में 'every one' के बाद का pronoun उसके वचन से मेल खाता है, अतः 'their' ही त्रुटि है।'No error' seemed right because many speakers use 'their' for a person of unknown gender. But in the exam Concept the pronoun after 'every one' agrees in number with it, so 'their' is the slip.
Answer और ExplanationAnswer and explanation
Answer: (C) has brought their own equipment
Every one एकवचन है, इसलिए verb एकवचन (has) है और उसका संदर्भ लेने वाला pronoun भी third person (अन्य पुरुष) singular होना चाहिए: his या her (his or her)। Their बहुवचन है और परीक्षा के Concept में agreement (सामंजस्य) भंग करता है।
✓
Every one of the students who participated in the national science fair has brought his or her own equipment.
शेष segments शुद्ध हैं।
सरल अर्थ: राष्ट्रीय विज्ञान मेले में भाग लेने वाला प्रत्येक विद्यार्थी अपना उपकरण साथ लाया है।
Every one is singular, so the verb is singular (has) and the pronoun that refers back to it is also third person singular: his or her (his or her). Their is plural and breaks the agreement in the exam Concept.
✓
Every one of the students who participated in the national science fair has brought his or her own equipment.
The other segments are correct.
