Choose the option that correctly combines the two sentences into one:
The exam hall was very cold. Some students wrote their papers with their shawls on.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → The exam hall was so cold that some students wrote their papers with their shawls on.
The first sentence gives a cause. The second sentence gives its result. The pair so ... that joins a cause to its result. “So” comes before the describing word (“cold”), and “that” begins the result.
Why the Other Options are Incorrect?
Option 1: The exam hall was too cold that some students wrote their papers with their shawls on. — Incorrect. “Too” does not pair with “that”. A result part beginning with “that” needs “so”.
Option 2: Although the exam hall was very cold, some students wrote their papers with their shawls on. — Incorrect. “Although” shows a contrast, but the two sentences show a cause and its result.
Option 3: The exam hall was so cold as some students wrote their papers with their shawls on. — Incorrect. In a result sentence, “so” pairs with “that”, not with “as”.
