Question 7 - Your Answer Was Incorrect
CLAIM: There is a small village in Ecuador, called Vilcabamba, whose inhabitants have an average lifespan of over 100 years.
ANSWER: FALSE. It was believed for many years that the residents of the Ecuadorian village of Vilcabamba lived to an unusually old age. This belief stemmed from a 1971 census that listed a high number of the village's 819 residents as being over the age of 100. But when anthropologists investigated this claim, they discovered that it was a hoax. Apparently, the Vilcabambans were lying about their age in order to attract more tourists to their village.
Question 9 - Your Answer Was Incorrect
CLAIM: Physicists recently announced that they were able to slow down light waves until the waves were almost frozen in place.
ANSWER: TRUE. Researchers at the Harvard-Smithsonian Center for Astrophysics announced in January, 2001 that they had used super-cooled vapor to slow down the velocity of light waves to zero, thereby freezing the energy of the light in an atomic 'spin wave.' It may seem odd to think of light being frozen in place. After all, light moves faster than anything else in the universe, traveling at 186,282 miles per second. But that's only in a vacuum. Light does slow down when it hits a substance such as air, water, or glass. It was essentially a matter of finding the right material to slow down the light without destroying the delicate light photons altogether. The researchers said that they hoped to use their light-freezing technique to create super-fast 'quantum' computers. Read more about it here.
