Problem:According to this criterion, the longest human lifespan is that of Jeanne Calment of France (1875 -- 1997), who lived to the age of 122 years, 164 days. She met Vincent van Gogh when she was 12 or 13. She received news media attention in 1985, after turning 110. Subsequent investigation found documentation for Calment's age, beyond any reasonable question, in the records of her native city, Arles, France. More evidence of Calment's lifespan has been produced than for any other supercentenarian; her case serves as an archetype in the methodology for verifying the ages of the world's oldest people.

Student A:Context: At 2040 UTC on November 7, Typhoon Haiyan made landfall in Guiuan, Eastern Samar at peak intensity. The JTWC's unofficial estimate of one-minute sustained winds of 305 km / h (190 mph) would, by that measure, make Haiyan the most powerful storm ever recorded to strike land.
