Answer: Option B

Explanation:

প্রশ্নে একটি বক্তব্য দেয়া আছে যে, 'সড়ক দুর্ঘটনা উল্লেখযোগ্যভাবে বেড়েছে।'

জানতে চাওয়া হয়েছে যে নিচে প্রদত্ত অপশনগুলোর মধ্যে কোনটি বাদে বাকিগুলো বক্তব্যটিকে জোড়ালো করে।

সঠিক উত্তর অপশন 2. Only well - trained drivers are allowed to run the cars.(শুধু সুপ্রশিক্ষিত চালকদেরই গাড়ি চালাতে দেয়া হয়।) কারন এটি বক্তব্যটিকে জোড়ালো করেনা, দুর্বল করে।

অপশন 2 বাদে বাকি অপশন গুলো হচ্ছে,

1. Drivers are running cars recklessly. (চালকেরা বেপরোয়াভাবে গাড়ি চালাচ্ছে।)

3. Road trafficking is almost absent. (যানবাহন চলাচলে নিয়ন্ত্রণ নেই বললেই চলে।)

4. Street trafficking is not working at night. (যানবাহন চলাচল নিয়ন্ত্রণ ব্যবস্থা রাতের বেলা কাজ করছেনা।)

এই অপশনগুলো বক্তব্যটিকে জোড়ালো করে।
