Read the following text. Put the paragraphs in the correct order

 

a) Not only this, but also there was a problem of plant fertilization, and how to distribute the oxygen evenly. Normally bees pollinate plants, but because glass cuts out ultra violet rays, which bees use to navigate, another solution had to be found. Hummingbirds were used. Generating waves mechanically in the ‘ocean’ was one of the ways to overcome the oxygen distribution problem.

b) Eight scientists got the go ahead to incarcerate themselves for two years in a giant greenhouse. The project aims to provide a working model of Earth, and is intended to function just like the real thing.

c) The project was set up jointly. The ideals came from a London – based ecology think tank, and the finance from a Texan billionaire. The huge steel and glass structure was built in the Arizona desert, and was not without its teething problems.

d) This project is expensive, though the organizers hope to make some of the money back by providing a series of viewing galleries, from which tourists could see a world at work.

e) Although their living in terms of food will be far from luxurious the scientists will be housed in a luxury block attached to the biosphere. You could easily imagine similar conditions for a colony living in space.

f) Every habitat has been recreated and contains most of the flora and fauna found in the original – dangerous and large animals have been left out. By installing a carefully calculated balance of prey and predator, a complete food chain has been established.

g) For example, the savanna grasses have to be broken down for recycling. This is done by termites, which, unfortunately, preferred the sealant around the panes of grass. The sealant had to be changed. Then there was the problem of how to seal the biosphere underground, and how to stop the air pressure blowing out the glass when it expanded in the sun’s heat. The former was solved by using plastic coated steel, the latter by, building a special pair of mechanical ‘lungs’ which expanded to accommodate the extra air volume.

h) But it was the decisions of what to grow and what to eat which most greatly affect the eight scientists. They will grow wheat, sorghum, potatoes, peas and beans, and raise some miniature pigs. The ocean will also have a small stock of fish.

9.4Give the tittles to each paragraph

9.5 Say what the different problems they had in designing the biosphere and how they were overcome

9.6 Something to think about

The American and Russian space programs were not only useful in terms of space exploration, but there were also many spin offs – inventions which came to be used in our everyday lives. Non-stick frying pans is an example. Can you think of any findings from this experiment that might be useful to us in the same way?
