Correct answer and explanation

Correct answer: (f)

Explanation: Context: The six sentences form a paragraph about Edison’s long effort to invent the electric bulb. The logical order is: (b) introduces Edison’s invention, (e) notes it was not overnight, (c) explains his experiments, (f) shows friends’ help, (a) gives the cost, and (d) closes with the conclusion. So the fourth sentence must continue the sequence by showing outside help. 1. (c) ❌ – this is the third sentence (explains experiments). 2. (f) ✅ – correct; comes fourth (friends searched worldwide). 3. (d) ❌ – conclusion; it is the sixth sentence. 4. (a) ❌ – expenditure follows the friends' search (fifth).
