Question: (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?

Question: Although international students want to dive into American culture, it is easier to stay close to the families.

"Most international students told me that they want to meet and make friends with as many Americans as they can," said Mark Galloway, Institute for International Studies (IIS) student adviser at prefix = st1 /StateUniversity.

"But in reality, they are comfortable with being around people from their own country, if possible. "

Testing of English as a Foreign Language (TOEFL) is an admission test for international students enrolling in American universities. Galloway said students' scores decreased when they spend less time with American students.

More than 450 international students are on campus at MurrayStateUniversity. Thailand, Japan,South Korea,ChinaandGermanyare countries with the most students this semester, according to an IIS report.

Wichien Eampromate, Thai Student Association President, said poor English ability and cultural differences make it difficult for Thai students to spend time with Americans.

"We eat different things; we do different kinds of things," said Eampromate.

On the other hand, Joon-Seong Bae, an exchange student from KoreaUniversity, said he tried to avoid hanging around other Koreans.

But it is not easy for him. He said he is less comfortable with Americans because he cannot say everything he wants to say, and not all Americans are patient with his limited English.

"There were two or three Americans and me," Bae said. "We talked about something. As time went by, I was kind of excluded because they talked to each other.

While international students venture outside their comfort zones, American students also have the opportunity to be exposed to other cultures.

"I know there are a lot ( of American students) who want to get to know international students," said Philip Lee, senior from Boonville,Indiana. "They are just uncomfortable. "

Lee said he has learned about life from his international friends, although it is sometimes a challenge.

" I can't live a comfortable life all the time," Lee said. " I realized there is a great benefit of stepping out of my comfort zone to meet people. " 1. Who are exchange students most comfortable around?
