Extract 2

Read the following extract carefully and answers the questions

Climate change is one of the most hotly contested environmental debates of our time. Will the West Antarctic ice sheet melt entirely? Will the Gulf Stream ocean current be disrupted? Will it be the end of the world as we know it? Maybe. Maybe not. Either way, Antarctica is a crucial element in this debate not just because it's the only place in the world, which has never sustained a human population and therefore remains relatively 'pristine' in this respect; but more importantly, because it holds in its ice-cores half-million-year- old carbon records trapped in its layers of ice.

(a) How does the absence of a human population in Antarctica make it significant in the climate change debate?

(b) Why is "climate change described as a "hotly contested" issue in the extract provided?

This is so, because there......

(i) is universal agreement on the causes and implications of climate change

(ii) is a planned path ahead about how to address climate change

(iii) are differing views on the causes and implications of climate change

(iv) are minimal reports of fresh threats to climate change

(c) The analogy of a time machine is an appropriate analogy for the role of carbon records in the study of climate change because..............

(d) Give one reason why the writing style of the extract can be called factual and informative.

Extract 3

Human civilisations have been around for a paltry 12,000 years-barely a few seconds on the geological clock. In that short amount of time, we've managed to create quite a ruckus, etching our dominance over nature with our villages, towns, cities, megacities. The rapid increase of human populations has left us battling with other species for limited resources, and the unmitigated burning of fossil fuels has now created a blanket of carbon dioxide around he world, which is slowly but surely increasing the average global temperature.

(a) A layer of carbon dioxide around the world is created due to:

(i) rapid decrease in human population.

(ii) burning of petrol, diesel, natural gas, coal, etc.

(iii) Both (i) and (ii).

(iv) burning of non-conventional fuels.

(b) A synonym of 'barely' is

(d) What is the name of the lesson?

Extract 4

Antarctica, because of her simple ecosystem and lack of biodiversity, is the perfect place to study how little changes in the environment can have big repercussions. Take the microscopic phytoplankton-those grasses of the sea that nourish and sustain the entire Southern Ocean's food chain. These single-celled plants use the sun's energy to assimilate carbon and synthesise organic compounds in that wondrous and most important of processes called photosynthesis.

(a) Why is ecosystem of Antarctica simple?

(i) Due to plenty of biodiversity.

(ii) Lack of oxygen.

(iii) Lack of animals and plants.

(iv) Lack of scientists.

(b) The entire Southern Ocean's food chain is sustained by…….

(d) Give a synonym of 'nourish.

Extract 5

The reason the programme has been so successful is because it's impossible to go anywhere near the South Pole and not be affected by it. It's easy to be blase about polar ice-caps melting while sitting in the comfort zone of our respective latitude and longitude, but when you can visibly see glaciers retreating and ice shelves collapsing, you begin to realise that the threat of global warming is very real.

(a) The name of the programme is……..

(b) Who is going to head the programme?

(i) High school students.

(ii) A group of scientists.

(iii) Geoff Green, a Canadian.

(iv) A group of navy sailors.

(d) Give an antonym of 'retreating'.

Extract 6

Six hundred and fifty million years ago, a giant amalgamated southern supercontinent- Gondwana-did indeed exist, centered roughly around the present-day Antarctica. Things were

quite different then; humans hadn't arrived on the global scene, and the climate was much warmer, heating a huge variety of flora and fauna. For 500 million years Gondwana thrived, but around the time when the dinosaurs were wiped out and the age of the mammals got under way, the landmass was forced to separate into countries, shaping the globe much as we know it today.

(a) The writer of the above extract is…….

(b) Gondwana is a:

(i) giant amalgamated southern supercontinent

(ii) giant amalgamated western supercontinent (iii) giant amalgamated northern supercontinent

(iv) Antarctica

(d) Give an antonym of 'thrived'.
