Passage 4
Every animal is a living radiator--heat formed in its cells is given off through its skin. Warm blooded animals maintain a steady temperature by constantly replacing lost surface heat; smaller animals, which have more skin for every ounce of body weight, must produce heat faster than bigger ones. Because smaller animals burn fuel faster, scientists say they live faster.
The speed at which an animal lives is determined by measuring the rate at which it uses oxy gen. A chicken, for example, uses one-half cubit centimeter of oxygen every hour for each gram it weights. The tiny shrew uses four cubit centimeters of oxygen every hour for each gram it weights. Because it uses oxygen eight times as fast, it is said that the mouse-like shrew is living eight times as fast as the chicken. The smallest of the warm-blooded creatures, tile humming-bird, lives a hundred times as fast as an elephant.
There is a limit to how small a warm-blooded animal can
A. have more skin for every ounce of body weight
B. replace lost heat faster
C. bum fuel faster
D. maintain a higher body temperature

Every year New Zealanders living in London can be seen loading up Kombi vans and heading off to experience the "classic European holiday", The trip usually starts in the north of France, after crossing the channel from Dover in England to Calais, driving down through France, over the Pyrenees into Spain, west into Portugal and then across the Continent to Italy and often beyond.
There are numerous reasons young New Zealanders take this rite of passage—as well as seeing all the fantastic sights and tasting the delights of Europe’s food and wine, it’s relatively inexpensive. The Kombi is transport and accommodation all in one, cutting down significantly on costs.
There is just one problem. As the Kombis become "antique", these trips are usually punctuated with numerous roadside sessions as the van sits idle, in no hurry to start, while you swelter in the hot sun. But do not let this deter you. Travelling Europe in your own vehic
