As
the New Year begins, I wish that it
will be a productive and rewarding
one for you, especially in the area
of your academic pursuit. I always
like to take this opportunity, at
the start of the year, to remind students
sitting the external examinations
in the summer, that these examinations
are only a few short weeks away. This
is not intended to scare you, but
rather to sharpen your focus on examination
preparations. Naturally, you want
to do well and, to realise this, you
must begin to review your work already
done, even from now. Do not try 'cramming'
at the last minute. This, undoubtedly,
is the formula for failure. May I
further suggest that you research
and or read your prescribed textbooks
on topics you have left to be done,
being guided by your syllabus, of
course. This is applicable to all
the subjects that you plan to sit
in the external examinations.
This
term is also the one that you have
to complete and submit the school-based
assessment (SBA) projects for the
different subject areas. Please try
to manage your time wisely as you
work at completing them on time, according
to the deadline your teachers have
set. If you had taken my suggestion,
given early in the last term, your
field report for the geography SBA
should be just about ready for submission.
With that out of the way, it means
that you have a little more time available
for the SBA for other subjects.
Last
month, I started to review the questions
given in the June 2008 examination
in Section D, the section that covers
topics from the syllabus under natural
hazards and environmental degradation.
As I indicated then, there are three
questions in this section, numbered
8 to 10. I have already gone through
question 8. Today, I will begin the
discussion on question 9. Here is
section (a) of that question.
Study
Table 7 which shows carbon dioxide
emissions per person and GNP per capita
for selected countries and answer
the questions below.

(i)
Which country had the SMALLEST increase
in carbon dioxide emission per person
between 1980 and 2001? (1 mark)
(ii)
Calculate the change in carbon dioxide
emissions per person for Canada. (2
marks)
(iii)
State the relationship between carbon
dioxide emissions and the GNP per
capita of the countries. (1 mark)
As
I pointed out before, for section
(a) of any given question on paper
two, a stimulus material is given.
This can be a diagram, map, chart,
table, among other things. Two or
three questions are given based on
the information in whatever is given.
In this question then, the answers
for the three questions are found
in the given table. So, take a few
minutes to study the table before
you attempt to write your answers.
Let
me offer some guidelines in arriving
at the answers for (i) and (ii) above.
For sub-section (i), look closely
at the figures given in columns two
and three for each country. You would
have observed that in 2001, the increase
in carbon dioxide emissions per person
occurred in three countries, namely,
Antigua, Jamaica and Grenada. Now
calculate the amount of increase in
these three then select the country
with the smallest increase.
Decrease
in carbon dioxide emission
For
sub-section (ii), notice that there
is a decrease in the emission of carbon
dioxide per person for Canada in 2001,
hence the negative value is the important
factor here.
Here
are the answers for section (a)
(i)
The country that had the SMALLEST
increase in carbon dioxide emissions
per person between 1980 and 2001 is
Jamaica.
(ii)
The change in carbon dioxide emissions
per person for Canada is - 2.9 tonnes
(iii)
The relationship between carbon dioxide
emissions and GNP per capita is that
countries with a large GNP have high
carbon dioxide emissions.
The
discussion continues in the next lesson.

are elated to receive copies
of the 2009 Adventist devotional,
'Always Joyful', from Pastor
Patrick Allen, president of
the Adventist Church in the
West Indies Union and chairman
of the board of governors of
NCU. The occasion was a courtesy
call on Allen recently, during
which they discussed various
issues affecting young people
in the church and society, in
general.
