Here’s the full response to the question, filling in the blanks appropriately and explaining them where needed:

Mia was suddenly taken ill at school. She felt very hot and her head ached terribly. The teacher insisted on taking her to the doctor. However, when Mia was brought to the school medical room, the doctor was out. The nurse took her temperature - it was very high, and she immediately called for the doctor. The doctor examined her.

"It's the fourth sick child since morning. The symptoms are the same. It's the flu." The doctor looked worried and upset. Then he addressed Mia: "When exactly did you start to feel unwell?"

"It was in Maths. We were writing a test when I started to feel weak and very tired. I wasn’t able to concentrate on the test."

"I see. I'll give you an injection, and you'll feel a bit better. We have to contact your parents so that they can collect you."

"I have called her mum already," the nurse said. "She'll be here soon."

"Fine. And we need to take measures to prevent the virus from spreading throughout the school." The doctor said that he had to see the headmaster, and Mia saw him leave the room. But she could not remember anything else - she’d fallen into a deep sleep.
