The students listened attentively to the lecture, but some of them found it so hard to understand.
Answer और ExplanationAnswer and explanation
Answer: (C) so hard to understand.
Concept (Too / So ... To के साथ 'Hard'): 'So' प्रायः 'so ... that' के साथ आता है, जबकि 'too ... to' का अर्थ है 'इतना ... कि नहीं'। यहाँ 'to understand' के आने से यह भाव है कि कुछ छात्रों को lecture समझना कठिन लगा। इसके लिए 'so hard to understand' के स्थान पर 'hard to understand' या 'too hard to understand' उपयुक्त है।
✓ Correct sentence: The students listened attentively to the lecture, but some of them found it hard to understand.
Exam trap: 'so ... that' संरचना से भ्रमित होकर 'so hard to understand' को सही मान लेना।
Concept (Too / So ... To with 'Hard'): 'So' is normally used with 'so ... that'. The sense here is that the lecture was difficult for some students to follow, so the structure 'hard to understand' is needed, or 'too hard to understand'. The phrase 'so hard to understand' is not correct.
✓ Correct sentence: The students listened attentively to the lecture, but some of them found it hard to understand.
Exam trap: being misled by 'so' and treating 'so hard to understand' as a correct pattern. The right choice is 'hard' or 'too hard'.
