24. Ans: C ব্যাখ্যা: 'Lest' এর পর 'should' বসে। "Lest we should miss..."।

25. Ans: C

28. Ans: D ব্যাখ্যা: "He works hard that he may succeed." এখানে 'that' উদ্দেশ্যমূলক Conjunction (so that অর্থে)।

29. Ans: B ব্যাখ্যা: "Nobody but Alam" (আলম ছাড়া কেউ না)। এখানে 'but' Preposition বা Conjunction হিসেবে ব্যবহৃত হতে পারে, তবে সাধারণত এটিকে Preposition ধরা হয় যখন এটি 'except' অর্থ দেয়, কিন্তু কিছু গ্রামারে এটি Conjunction হিসেবেও আলোচিত হয়। প্রশ্নে অপশন অনুযায়ী 'but' সঠিক।

33. Ans: D

ব্যাখ্যা: 'Than' এখানে দুটি ক্লজকে তুলনা করছে (He is taller than I am), তাই এটি Conjunction।
