input: Make use of the article to answer the questions. (CNN) -- Nick Heidfeld has left his role as reserve driver at Mercedes to become a tester for Pirelli ahead of the Italian company's return to Formula One as the sport's sole tire supplier next year.

The 33-year-old German had driven in F1 for a decade but was left without a seat when BMW ended its association with the Sauber team at the end of last season.

He was given a lifeline when Mercedes took over the world champion Brawn GP team this year, becoming back-up to returning seven-time world champion Michael Schumacher and Nico Rosberg.

"I would like to thank Ross Brawn, Norbert Haug and Nick Fry for allowing me the opportunity to become Pirelli's official test driver," Heidfeld told F1's official website.

"The team has always said that they would not stand in my way if such a chance arose, and they have kindly allowed me to take up this exciting new role."

Mercedes team principal Ross Brawn said: "Nick is an extremely experienced driver and we are confident that his racing knowledge and technical feedback will prove extremely useful to Pirelli and therefore of benefit to the sport as a whole."

Mercedes-Benz Motorsport vice-president Haug said the move might help Heidfeld find a drive for 2011.

"It would be great to see Nick in a competitive car in next year's world championship and I am sure his leading role in the new tire development, in addition to his skills, puts him in a good position for the remaining seats in 2011," Haug said. 1. How old is Nick Heidfeld?

input: (CNN) -- North Korean leader Kim Jong-il has added his brother-in-law to a military board in a move analysts say paves the way for an heir, according to South Korea's state-sponsored Yonhap news agency.

Kim Jong-il has named his brother-in-law Jang Song Thaek to a top military board.

The addition of his kin to the powerful National Defense Commission also solidifies his standing, Yonhap said.

Kim was reappointed Thursday as chairman of the military board in his first major public appearance since a reported stroke in August. His brother-in-law, Jang Song Thaek, is considered his right-hand man, according to Yonhap.

Jang, who has been married to Kim's sister since 1972, currently serves as a director of the Workers' Party, Yonhap said.

"Kim wants to keep the military in check and secure loyalty to both the military and the party," Cha Doo-hyeogn, a North Korea expert, told Yonhap.

Kim also increased the number of members in the military agency to 13, from eight, Yonhap said.

"Overall, the power of the National Defense Commission was strengthened," Seoul's Unification Ministry spokesman, Kim Ho-nyoun, told Yonhap in a briefing.

There were no other major changes in the new parliament, which signifies that Kim, 67, is prepared to maintain the status quo as he readies someone to take over from him, analysts told Yonhap.

Kim's recent health problems and long absence from public functions have prompted speculation on whether he is ready to groom an heir to the world's only communist dynasty.

Q: (CNN) -- He may be a long way from the football field, but Pele at least is back to talking and getting better at a Sao Paulo, Brazil, hospital.

The city's Albert Einstein Hospital issued a statement Saturday saying the football legend -- born Edson Arantes do Nascimento -- was improving but still in intensive care battling an illness.

Pele is lucid, talking and responding to antibiotics, the hospital said. He remains on temporary dialysis, which was a reason he was moved to the ICU in the first place, because the machine he needed was there.

The hospital issued a second statement later Saturday, indicating that Pele continues to recover and that doctors plan to take him off dialysis early Sunday.

Earlier this week, the 74-year-old was admitted to the medical facility -- the same place he recently underwent surgery to remove kidney stones -- for a urinary tract infection.

The athletic icon had one kidney removed during this days as a player, his aide, Jose Fornos Rodrigues, told CNN.

Pele tweeted Thursday that he was looking forward to spending the holidays with family and starting "the new year with renewed health, with many international trips planned."

"I am blessed to receive your love and support," Pele said, "and thank God this is nothing serious."

Known as "The Black Pearl" and simply "The King," Pele is one of the best known names in all of sports.

He burst onto the scene as a teenager, helping lead his native Brazil to the 1958 World Cup championship. Pele went on to star on two other World Cup title teams as well, in 1962 and 1970, in addition to a breakthrough career with the Brazilian club Santos and later with the New York Cosmos of the now-defunct North American Soccer League.

Answer the following questions:
1. Who is back to talking and getting better at Sao Paulo Brazil, hospital?
2. What did the Hospital's statement say?
A:
1. Pele
2. he was improving
