Some time between digesting Christmas dinner and putting your head back down to work, spare a thought or two for the cranberry. It is, of course, a (1) of Christmas: merry bright red, bittersweetly delicious with turkey and the very devil to get out of the tablecloth (2) spilled. But the cranberry is also a symbol of the modern food industry and in the tale of its (3) from colonial curiosity to business - school case study (4) a deeper understanding of the opportunities and (5) of modern eating.
The fastest growing part of today’ s cranberry market is for cranberries that do not taste like cranberries. Ocean Spray’ s "flavoured fruit pieces" ( FFPS, to the trade) taste like orange, cherry, raspberry or any (6) of other fruits. They are in fact cranberries. Why make a cranberry taste like an orange Mostly because it is a (7) little fruit: FF PS have a shelf-life of two years. Better (8) , they keep a chewy texture (9) baked, unlike the fruits whose flavours they mimic, which turn to (10) .
The dynamic that has brought the cranberry to this point is (11) to the dynamic behind most mass-produced goods. Growing (12) provided the (13) to create cheaper and more reliable supply. Cheaper and more reliable supply, (14) , created incentives to find new markets, which increased demand. Thus was the (15) kept churning.
The cranberry is one of only three fruits native (16) North America, growing wild from Maine to North Carolina. (The others are the Concord grape and the blueberry. ) The American Indians had several names for cranberries, many (17) the words for "bitter" or, more (18) , "noisy". They ate the berries mostly (19) pemmican, but also used them for dye and medicine. And they introduced them to the white settlers--at the first Thanksgiving dinner in 1621, it is said. The settlers promptly renamed this delicacy the "crane berry", (20) the pointy pink blossoms of the cranberry look a bit like the head of the Sandhill crane.

The molecules of carbon dioxide in the Earth’s atmosphere affect the heat balance of the Earth by acting as a one-way screen. (1) these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concerned, to pass (2) , they absorb some of the longer-wave length, infrared emissions radiated from the Earth’s surface, radiation that would (3) be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the planet must (4) incoming solar radiation. If there were no carbon dioxide in the atmosphere, heat would (5) from the Earth much more easily.
Today, (6) , the potential problem is too much carbon dioxide. Could the increase in carbon dioxide (7) a global rise in average temperature, and could such a rise have serious (8) for human society Mathematical models that allow us to calculate the rise in temperature as a function of the increase (9) that the (10) is probably yes.
One mathematical model (11) that doubling the atmospheric carbon dioxide would raise the global mean surface temperature by 2.5℃. This model assumes that the atmosphere’s relative humidity remains constant and the temperature decreases with altitude at a (12) of 6.5℃ per kilometer. The assumption of constant relative humidity is important, because water vapor in the atmosphere is another (13) absorber or radiation at infrared wavelengths. Because warm air can hold more (14) than cool air, the relative humidity will be constant (15) the amount of water vapor in the atmosphere increases (16) the temperature rises. (17) , more infrared radiation would be absorbed and reradiated (18) to the Earth’s surface. The resultant warming at the surface could be expected to melt snow and ice, (19) the Earth’s reflectivity. More solar radiation would be absorbed, (20) to a further increase in temperature.
