Read the passage and answer the question that follows.

Sniffer dog Tucker uses his nose to help researchers find out why a killer whale population off the northwest coast of the United States is in decline. He searches for whale faeces floating on the surface of the water, which are then collected for examination. He is one of an elite team of detection dogs used by scientists studying a number of species including right whales and killer whales.
Scientists have been using Conservation Canines in their research since 1997. These dogs have enabled them to noninvasively access vast amounts of genetic and physiological information which is used to tackle conservation problems around the world. Such information has proved vital for determining the causes and consequences of human disturbances on wildlife as well as the actions needed to mitigate such impacts.
The ideal detection dog is extremely energetic with an excessive play drive.  These dogs will happily work all day long, motivated by the expectation of a ball game as reward for sample detection. The obsessive, highenergy personalities of detection dogs also make them difficult to maintain as pets. As a result, they frequently find themselves abandoned to animal shelters, facing euthanasia. The programme rescues these dogs and offers them a satisfying career in conservation research.

Read the passage and answer the question that follow. 
"Counting"
Archaeologists believe that counting large quantities began about 10,000 years ago. Early farmers had to account for communally stored crops. Early counting systems involved the use of small tokens which represented farmers' stores. In the area which is now Southern Iraq, little figures shaped like discs, balls and pyramids were used from about 7500 BC, to represent various holdings. Later, marks which represented the figures were inscribed on clay tablets by use of a blunt reed to cut into the wet clay. Still, the symbols were always connected with specific merchandise. Around 3000 BC, people began using clay tablets and a now accounting system which they perfected over the next 4.000 years. A writing system called cuneiform, which consisted of wedge-shaped symbols, was also invented. At the same time, other cultures were independently developing numbering and writing systems. Soon philosophers began to discover that nature was subject to laws which could be expressed with numbers. 

LEARNING FROM MISTAKES
                                        By Peter Hall
I have finally come to the place
Where things can come off the shelf
So I can try to learn from mistakes
And not be so hard on myself.

I no longer need to be opaque
It's time for me to see
That my failures and past mistakes
Do not label me.

No longer trusting what used to assure
Sorting out things that will last
Mistakes filter out what really endures
Permitting to learn from the past.

I know life has its ups and downs
I can't help things don't go to plan
But mistakes no longer bring 'that frown'
Now that I know who I am.

Read the following passage and answer the question that follows.
Thick, black, smoke curling out of smokestacks, horrible - tasting chemicals in your drinking water, pesticides in your food - these are examples of pollution.
Pollution is any contamination which causes harm to the environment or its inhabitants. There are many kinds of pollution, and there are many pollutants. Some obvious kinds of pollution are air, soil, and water. Some less obvious, or less well-known kinds of pollution are radioactive, noise, light pollution, and green-house gases.
Air pollution can be caused by particles, liquids, or gases that make the air harmful to breathe. There are two main types of air pollution - primary and secondary. Primary pollutants enter the air directly, like smoke from factories and car exhaust pipes. Secondary pollutants are chemicals that mix together to pollute the air like mixtures of emissions, or waste output from vehicles and factory smoke that change to form more dangerous pollutants in the air and sunlight.
Soil pollution can be caused by pesticides, leakage from chemical tanks, oil spills, and other chemicals which get into the soil through dumping or accidental contamination. Soil pollution can also cause water pollution when underground water becomes contaminated by coming into contact with the polluted soil.
Water pollution can be caused by waste products such as sewage, oil spills, and litter in streams, rivers, lakes, and oceans. Some scientists believe that water pollution is the largest cause of death and disease, causing about 14,000 deaths In the world each day.
