Journey to the End of the earth

 Class XII

No. 1) Multiple Choice Questions based on an extract:

You lose all earthly sense of perspective and time here. The visual scale ranges from the microscopic to the mighty: midges and mites to blue whales and icebergs as big as countries (the largest recorded was the size of Belgium). Days go on and on and on in surreal 24-hour austral summer light, and a ubiquitous silence, interrupted only by the occasional avalanche or calving ice sheet, consecrates the place. It’s an immersion that will force you to place yourself in the context of the earth’s geological history. And for humans, the prognosis isn’t good.

i. The ‘visual scale’ refers to

a. a measuring device

b. range of things one can see

c. visionary’s belief

d. the magnitude of preparation

Q. No. 2) Read the given extract and answer the questions given:

 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.


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

Ans. This makes it an important reference point for understanding the effects of human activities on the environment and the potential impacts of climate change.[The absence of a human population in Antarctica means that the region is relatively pristine and has not been subject to the same levels of human impact as other areas of the world.]

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

This is so, because there _____.

a. is universal agreement on the causes and implications of climate change

b. is a planned path ahead about how to address climate change

c. are differing views on the causes and implications of climate change

d. are minimal reports of fresh threats to climate change

Ans. Option (c)

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

Ans. ... just like a time machine would allow us to observe past events, carbon records allow us to observe past climate conditions. [ Carbon records allow us to study past climates by analyzing the air bubbles trapped in ice cores. They provide a glimpse into the Earth's atmospheric conditions at the time the ice was formed and can help scientists understand how the climate has changed over time.]

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

Ans. (Anyone)

  • ...because the writer presents information in a straightforward and objective manner
  • ...because the writer applies a third-person point of view and avoids the use of personal opinion or emotional language
  • ...because the writer uses a logical structure to present their argument (starting with the importance of Antarctica as a relatively pristine location, and then moving on to explain the significance of the ice cores and carbon records found there)

Q. No. 3) “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...”

With respect to the given statement from the text, choose the option to replace the underlined set of words.

a. stays as it is throughout the year.

b. becomes a perfect place to travel.

c. is left to be an uncorrupted area.

d. abides by the strict laws of nature.

Ans. Option (c)
