PROBLEM: Article: I was thirteen when my father got hurt.Looking back over the years, I sometimes wonder what I could have done differently that day.Spit twice over my shoulder when I saw the single magpie , maybe.But that's the thing about superstitions .You don't know how much power they have until you break them. We lived in a dark shabby house in Bucks.Wood blocks laid over dirt on the floor.That part of England was full of cherry trees.Chalky soil. The rice had caught in the bottom of the pot that morning at breakfast and all I could smell was burned rice.Even now when I think of that day I have the taste of burned rice in my mouth. "I'm going to cut down the old cherry tree," my father announced. "You've been saying that for years," said my mother lightly touching the end of her nose.Her nose ran all year long.Her arms rested on the table, a cup of tea placed between her hands, steam rising into the air."You'll never get round to it." My stomach, balled into a tight little knot relaxed itself. "Millie's going to cry if you cut it down," said my younger brother, Simon, his eyes bright as a fox."Silly Millie, silly Millie." "Hold your noise," said my father patting Simon on the head."And put back that butter.That's a week's ration you've got on your plate." "The war's over," said Simon in a low voice."We haven't had rationing for ages." Simon was right.Even sugar had come off points.However, we still occasionally received food parcels from distant cousins in Canada. My father glared at him and then went on. "Pigs.Burt says he'll come and help me take the tree down if he can have some of the wood." "No," I said springing to my feet."You can't do it.That's my tree.Always has been.Always will be.I won't let you." Tom, took a piece of toast, watching my reaction.My older brother, he knew what the tree meant to me. "Now then, Millie," said my father softening his face."That tree's wild.It's in the way."

SOLUTION: According to the passage, how many kids does the family have at least?

PROBLEM: Article: Joseph Francis Charles Rock (1884-1962) was an Austrian-American explorer, botanist, and anthropologist . For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949. In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China's southwestern provinces--the Wild West of their day. But gold and silver weren't his task: Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum . Botany, though, was just one of Rock's strengths. As an ethnologist , he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China's "Cho-Ni" territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II. Scientist, linguist, cartographer, photographer, writer--Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord's place "as if he owned the place," said Lisa Pearson, the Arboretum's head librarian. In declaring his successful return under the headline "Seeking Strange Flowers, in the Far Reaches of the World," the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. "In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance." The Arboretum and Rock parted ways after 1927, mainly because his trip cost Harvard a fortune--about $900,000 in today's dollars. Fortunately, many of his specimens, many of his amazing photos, and his great stories remain.
Answer: Rock's exploration in Southwest China.
