input: Yaounde, Cameroon (CNN)Cameroonian troops and their allies have freed a German man who was held for six months by Islamist terror group Boko Haram, Cameroonian President Paul Biya said.

Boko Haram kidnapped German citizen Robert Nitsch Eberhard in Nigeria in July, Biya said in a statement read Wednesday on state-run broadcaster CRTV. He did not detail how, when or where the rescue operation took place.

"A special operation of Cameroonian armed forces and security services of friendly countries" freed the man, he said.

Eberhard told journalists he was glad to be alive.

"I am happy to see all these people around me, who have rescued me and made sure that I survived, because until the last minute, I did not know whether I would survive or I would not survive. It was for me a big problem. Because it was darkness, total darkness, and you see nobody around you. Then this is a big problem to say OK, I will survive or not survive," Eberhard said.

Eberhard was flown in from Cameroon's Far North Region to Yaounde shortly after noon Wednesday.

He said he was grateful to all those who worked to secure his release.

The German ambassador to Cameroon, Klaus-Ludwig Keferstein, also thanked Cameroonian authorities, particularly because "we could find a solution to this problem of hostage-taking," he said.

Eberhard spoke amid heavy security and mentioned that he was teaching at a vocational school in Gombe, Adamawa state, Nigeria, before the insurgents took him hostage in July.

He has been taken to the residence of the German ambassador in Yaounde. The ambassador said initial medical care will be given to him before he is flown back to Germany for more medical attention. 1. Who is Cameroonian President?

input: Robert and Peter study in the same university. They do everything together and help each other. But they often play jokes on each other. The school year was over last month and they decided to travel through the country in America. They drove a car and could stop wherever they were interested in and started whenever they wanted. Of course they enjoyed themselves. It was very hot one day and they were both hungry and thirsty. They stopped in front of a restaurant by the road. They came in, sat down at a table and ordered some dishes. Robert looked around and found there was a small bowl on the table. He thought there was some ice cream in it and took a spoonful of it and put it into his mouth. Immediately he knew it was mustard ,but it was too late. Tears ran down his face, but he pretended nothing had happened. The other young man, seeing his friend crying, asked, "What are you crying about, Robert?" "I'm thinking of my father who was hanged twenty years ago," was his reply.

After a while, Peter made the same mistake. Tears ran down his cheeks, too. And his friend asked him why.

"I wonder why your father hadn't been hanged before he got married!" 1. How did the guys chose to travel?
