Text VI
This is the first chapter of the mythic Star Wars saga.
Set thirty years before the original Star Wars film, Episode I introduces young Anakin Skywalker, a boy with special powers, unaware that the journey he is beginning will transform him into the evil Darth Vader.
Obi-Wan Kenobi, the wise old Jedi from the original series, is a determined young apprentice and Palpatine, well known as the evil Emperor, is an ambitious Senator in the Galactic Republic.
It is a time when the Jedi Knights are the guardians of peace in a turbulent galaxy and a young Queen fights to save her people. In the shadows an evil force is waiting for the right moment to strike.

Acid rain and… the facts
www.acidrain.org.ca / Oxford Children´s Encyclopedia
What causes acid rain?
Acid rain is caused by air pollution. When fossil fuels such as coal and oil are burned, two gases, sulphur dioxide and nitrogen oxide, are released into the atmosphere. These two pollutants eventually react with the moisture in the air. When this polluted mixture falls onto the ground, it is called acid rain.
Rain measuring between 0 and 5 on the pH scale, is acidic therefore called ACID RAIN
Acid rain is harmful to the environment. It is hard to control because it may be blown by the wind, falling thousands of kilometers from where it was first formed. For example, much of the acid rain in Canada is caused by smoke from factories and power‐stations in the USA. The acid rain in Scandinavia may come from Britain.
What are the effects of acid rain?
Acid rain has many different effects. It has killed fish in the lakes of North America, Scandinavia, Scotland, and Wales. Vast areas of forest in northern and central Europe are dying because of it, while in many European cities statues and stone buildings are being eaten away by the acid. Acid rain corrodes metalwork such as steel bridges and railings; it also attacks some types of concrete. Even the water that we drink is slowly being polluted by acid rain.
What are the effects on trees and soil?
One of the most serious impacts of acid precipitation is on forests and soils. Great damage is done when sulphuric acid falls onto the earth as rain. Nutrients present in the soils are washed away. Aluminium also present in the soils is freed and this toxic element can be absorbed by the roots of trees. Thus, the trees starve to death because they have been deprived of their vital nutrients such as calcium and magnesium.
Acid rain is one of the most serious environmental problems of our time. It is a global problems that is gradually affecting our world.
How does acid rain effect lakes?
Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, various types of fish disappear. Other effects of acidified lakes on fish include: decreased growth, inability to regulate their own body chemistry, reduced egg deposition, deformities in young fish and increased susceptibility to naturally occurring diseases.
Clean rain usually has a pH of 5.6. It is slightly acidic because of carbon dioxide which is naturally present in the atmosphere. Vinegar, by comparison, is very acidic and has a pH of 3.
What is pH?
This is a measure of how acidic or alkaline a substance is. (See a pH scale below). The initials pH stand for Potential of Hydrogen. Acids have pH values under 7, and alkalis have pH values over 7. If a substance has a pH value of 7. It is neutral‐neither acidic or alkaline.

Because the pH scale is logarithmic, a difference of one pH unit represents a tenfold, or ten times change. For example, the acidity of a sample with a pH of 5 is ten times greater than that of a sample with a pH of 6. A difference of 2 units, from 6 to 4, would mean that the acidity in one hundred times greater, and so on.

Questions 34 through 38 refer to the following text.
We've been keeping our veterinarian in business lately.
First Sammy, our nine-year-old golden retriever, needed
surgery. (She's fine now.) Then Inky, our curious cat,
burned his paw. (He'll be fine, too.) At our last visit, as we
were writing our fourth (or was it the fifth?) consecutive
check to the veterinary hospital, there was much joking
about how vet bills should be tax-deductible. After all, pets
are dependents, too, right? (Guffaws all around.)
Now, halfway through tax-filing season, comes news
that pets are high on the list of unusual deductions
taxpayers try to claim. From routine pet expenses to the
costs of adopting a pet to, yes, pets as "dependents," tax
accountants have heard it all this year, according to the
Minnesota Society of Certified Public Accountants, which
surveys its members annually about the most outlandish
tax deductions proposed by clients. Most of these doggy
deductions don't hunt, but, believe it or not, some do. Could
there be a spot for Sammy and Inky on our 1040?
Scott Kadrlik, a certified public accountant in Eden Prairie,
Minn., who moonlights as a stand-up comedian (really!),
gave me a dog's-eye view of the tax code: "In most cases
our family pets are just family pets," he says. They cannot
be claimed as dependents, and you cannot deduct the
cost of their food, medical care or other expenses. One
exception is service dogs. If you require a Seeing Eye
dog, for example, your canine's costs are deductible as
a medical expense. Occasionally, man's best friend also
is man's best business deduction. The Doberman that
guards the junk yard can be deductible as a business
expense of the junk-yard owner, says Mr. Kadrlik. Ditto the
convenience-store cat that keeps the rats at bay.
For most of us, though, our pets are hobbies at most.
Something's a hobby if, among other things, it hasn't turned
a profit in at least three of the past five years (or two of the
past seven years in the case of horse training, breeding
or racing). In that case, you can't deduct losses—only
expenses to the extent of income in the same year. So if
your beloved Bichon earns $100 for a modeling gig, you
could deduct $100 worth of vet bills (or dog food or doggy
attire).
