Types of Industry &

1.
Physical Environment- The most
undeveloped economies have
the
majority of their workers in the
physical
environment sector; most of the
economy
engages in farming, hunting and
fishing.
2.Raw Materials-
The raw material industries
process materials such as iron
ore so that the raw materials
can
be fabricated into useful
products.
3.
Services-
The service industry is very
diverse. Those in
the service industry take sales
orders, care for animals, handle
airport baggage, give advice,
help children cross the street,
provideproduct
information, perform massages,
embalm the
deceased, maintain buildings and
perform
various other services.

type of farming system
where the farmer produces
food for his family and his
self.
(3aii)Comnercial type of farming

and for sales. This involves
the use of machines like
tractors etc.Labour is hired
to executive it.

d govt & d
nation
(ii). Provision of food to d

(iii) it is d largest employer of
labour
hence; avenue 4 d creatn of
employment
opportunities
(iv) it provides cash goods 4
export,
therefore leading to earning of
foreign
currencies
(v) it provides raw materials 4 d
domestic
industries.
(5a) -stimulation of other
sectors: the
industrial sector stimulates the
growth of
other sectors
-improvement in standard of
living: it
leads to raising of standard of
living of the
people through production of
goods and services.
-control of inflation: with
modern
technology, products car,
machinery etc
can be mass produced.
(5B)
-acquisition of skill: skills should
be acquiredfor industrial
operations
-local sourcing of raw materials:
there
should be exploitation of raw
materials
locally for industries
-creation of industrial zone: this
will
provide a cnducive environment
with all the infrastructural
facilities for the
industries.
-good government policies:
there should
be good policies to encourage

(12a) The four problems of
barter economy are:
(i) problem of double
coincidence of want- This was
one of the major problems of
barter economy as the individual
has to look for someone that
has what he or she want and at
the sametime want to exchange
it wit his own.
(ii) No store of value: perishable
goods cannot provide store of
value.
(iii) lndivisibilty: some comodity,
example, house cannot easily be
put denominations- thus making
exchanhe dificult.
(iv) Constraint in borowing and
lending operations of borrowing
and lending is not possible in a
barter ecomony.

12b)
-mdium of exchange: it serves as
a
medium through which people
can exchange goods and services
and it solve
the problem.
-standard for deterred
payments: it makes
future payment possible when
goods are
bought on credit which barter
can not do

[6a]
(i)direct taxes are levied on
income of
individuals and corporate bodies
while
indirect taxes are levied on
consumption or individual and
corporate
bodies (ii) tax yield from direct
tax cam be
pre-determined by the govt
while the
indirect tax cannot be pre-
determined
(iii)direct tax incidence falls on
the tax
payer whereas,the indirect tax
incidence may be shared
between the consumer or the
producer depending on
the price elasticity of demand
(iv)income from indirect tax is
the
major source of govt revenue
while
that of a direct tax is not the
major
sources.
(6b)
(i)it is used to discourage
consumption
of harmful product

Textbooks|5.00.
Shirt |2.00
shoes |3.00 trousers |3.00
notebooks|1.00
school fees|7.00
marthress|10.00.
Mr. Smiths disposable income :
$7.00.
(2ai)frm the scale of preference.
Mr smith will spend his money
on textbook
and shirt.
(ii) the reason why he should
expend his
money on two items above is
that they
are the pressing need and his
income is
$7.00 whch wil meet the money
cost of the items.
(2bi)The opportunity cost
