Question

Q1. Read the passage given below and answer the questions that follow:
1. It is found that 40 million years ago, parts of Antarctica, one of the coldest places on earth,
were as warm as today's Califomia coast with temperatures as high as 17 degrees Celsius.
Today Antarctica is year - around one of the coldest places on earth and the continent's
interior is the coldest place with annual average land temperatures far below zero degree
Fahrenheit
2. Researches also found that some of the polar region of the southern Pacific Ocean once
registered Florida heat. The finding underscore the potential the potential for increased warmth
at the earth's poles and the associated risk of melting polar ice and rising sea levels, the
2nd Paper
English
researchers said
3. The researchers, who were scientists at Yale university, focused on Antarctica during the
Eocene period, which dates back to 40-50 million years ago. This period is marked by high
concentrations of atmospheric CO2 and consequently a greenhouse climate. During this period
of time, little to no ice was present on earth and the difference in temperature was much
smaller, from the equntor to the poles. Recently, the early Eocene has received considerable
interest because it may provided insight into the response of Earth's climate and biosphere to
the high atmospheric carbon dioxide levels that are expected in the near future.
4. This new model can help predicting future climate, according to co-author Hagit Affek,
associate professor of geology and geophysics at Yale. According to him, quantifying past
temperatures helps scientists to understand the sensitivity of the climate system to greenhouse
gases and specially the amplification of global warming in polar regions.
5. In the course of their research, scientists have found a novel way of coming to the present
conclusion about the Antarctic climate. By studying concentrations of rare isotopes in ancient
fossil shells, the scientists were able to establish their finding about temperatures in parts of
Antarctica reaching as high as 17 degrees Celsius during Eocene period. Their other conclusion
has been that the average temperature during the period was around 14 degrees Celsius, which
is similar to the average temperature of the coast of California today.
Q. Attempt any cight of the following questions on the passage you have read.
(a) What does the finding about Antarctica 40 million years ago reveal?
(b) What is the continent's interior regarded as?
(C) What do scientific findings about soine of the polar regions of the southern Pacific Oce
Show?
(d) What do the finding of the scientists at Yale University tell?
(e) What was the difference in the temperature in the Eocene period?
(0) Why has the Eocene period received much attention in recent times?
(@) What is the view of Prof. Affek about scientist?
(6) Why have the scientist studied isotopes in ancient cells.
) Which word in para 2 means the same as possibility"?​

Answer 1

Answer:
