Прочитайте приведённый ниже текст. Преобразуйте слово, напечатанное заглавными буквами в скобках так, чтобы оно грамматически соответствовало содержанию текста. Заполните пропуск полученным словом.

The phone rang in Clark Taylor’s house at nearly three in the morning. He answered it only after the __________________(FIVE) ring. “Hello,” Clark said in a sleepy voice. “Mr. Taylor. Thank goodness. I need your help.”Clark definitely __________________(KNOW) the voice. However, he was sleepy and __________________(NOT/CAN) remember who it was. “Mr. Taylor!” the man said. “I am in trouble. The police allowed me only one phone call. And I am calling you.”Then, the fog cleared. Although nearly ten years had passed since __________________(THEY) last meeting, Clark was able to recognise the voice. It belonged to Martin Hall, one of the __________________(BRIGHT) math students he had ever had. “Martin, what’s happened? Where are you? ” Clark asked. “In the police station. I __________________(ARREST) at the railway station two hours ago. I was going to a conference. The police mistook me for another person. The irony is that I really do look like the criminal that they are looking for.Besides that, I __________________(LOSE) my ID card and I can’t prove who I am. You are the only person in this town who knows me. Can you help me?” Martin Hall asked. “If you give me the address, I __________________(COME) at once,” Clark said, jumping up of the bed. It was not difficult for him to prove that Martin Hall was his former student. Clark brought a scientific journal with Martin’s article and a photo of him. The __________________(POLICEMAN) were surprised to find out that their prisoner was a capable young scientist.
