8. दिइएको गद्यांश पढी सोधिएका प्रश्नहरूको उत्तर दिनुहोस् :
नेपाली समाजमा सामान्यतः सरस्वतीको बन्दना गराएपछि शिक्षारम्भ गराइन्छ । रामशरणको शिक्षारम्भ भने फरक किसिमले भएको थियो । उनले कखराबाट नभएर सारेगमबाट गरेका थिए । उनी आफ्ना घरमा प्राय : बजिरहने ट्रम्पेट, कर्नेट र अग्र्यानको सुमधुर ध्वनिबाट बाल्यकालदेखि नै प्रभावित थिए । यसैले तिनै बाजाबाट शिक्षारम्भ गर्न उनलाई सहज पनि भएको थियो । उनी एघार वर्षकै उमेरमा ती बाजा बजाउन सक्ने भइसकेका थिए । बाजा बजाउने कामसँगै पढाइको कार्यलाई पनि क्रमश: अघि बढाउँदै लगे । घरमा आफ्ना पिताका सङ्कलनमा रहेका पुस्तकले बिस्तारै बिस्तारै उनलाई अध्ययनमा पनि रुचि जगाइदिएका थिए । उक्त सङ्कलनमा त्यति धेरै पुस्तक नभए पनि उनका लागि भने रुचि जगाउनका लागि ति पर्याप्त थिए । उनका पिता पुस्तक सङ्कलनमा रुचि राख्थे । त्यसैले बजारमा नयाँ पुस्तक देखेपछि किन्न पछि पर्दैनथे । रामशरणलाई सानो हुँदा लालहिरा, चार रङका माछा, शर्मिष्ठा, हात्तीमताई जस्ता पुस्तक मन पर्थे ।
