She studied hard for the exam, and she didn’t get a good score because she was too nervous.
Answer और ExplanationAnswer and explanation
Answer: (D) The conjunction "and" should be replaced with "but."
Concept (Contrast Conjunction: But): जब दो clauses में विरोध या अप्रत्याशित परिणाम दिखाना हो, तब 'but' जैसा Contrast Conjunction चाहिए। यहाँ मेहनत से पढ़ने पर अच्छा अंक मिलना चाहिए था, परन्तु ऐसा नहीं हुआ; यह अपेक्षा के विपरीत परिणाम है। अतः 'and' के स्थान पर 'but' आएगा।
'because' यहाँ सही है, क्योंकि वह कारण बताता है; 'so' रखने पर कार्य-कारण का क्रम उलट जाएगा।
✓ शुद्ध वाक्य: She studied hard for the exam, but she didn't get a good score because she was too nervous.
Examiner का trap: अप्रत्याशित परिणाम वाले वाक्य में 'and' को सही मान लेना ही इसका जाल है; यहाँ 'but' आता है।
Concept (Contrast Conjunction: But): when two clauses show opposition or an unexpected result, a contrast conjunction such as 'but' is needed. Here studying hard should have given a good score, but she did not get one. That is an unexpected result, so 'and' is replaced by 'but'.
'Because' is correct here, since it gives the reason; with 'so' the cause and effect would be reversed.
✓ Correct sentence: She studied hard for the exam, but she didn't get a good score because she was too nervous.
Exam trap: accepting 'and' in a sentence that shows an unexpected result. The correct connector is 'but'.
