-Marine insurance covers the loss or damage of ships, cargo, terminals, and any transport or cargo by which property is transferred,
acquired, or held between the points of origin and final destination. Cargo insurance —
discussed here — is a sub-branch of marine
insurance, though Marine also includes
Onshore and Offshore exposed property, container terminals ports, oil platforms pipelines), Hull, Marine Casualty, and Marine
Liability. When goods are transported by mail or courier, shipping insurance is used instead.

-accidental death and
dismemberment (AD&D) is a policy that pays benefits to the beneficiary if the cause of death is an accident. This is a limited form of life insurance which is generally less
expensive.

- Group insurance is an insurance that covers a
defined group of people, for example the
members of a society or professional
association, or the employees of a particular
employer. Group coverage can help reduce
the problem of adverse selection by creating
a pool of people eligible to purchase insurance
who belong to the group for reasons other than the wish to buy insurance, which might be because they are a worse than average
risk.Group insurance may offer life insurance, health insurance, and/or some other types of
personal insurance.

- Fidelity Guarantee insurance is an insurance policy designed to indemnify the Insured (the employer) for the loss of money or property
sustained as a direct result of acts of fraud,
theft or dishonesty by an employee in the
course of employment.

- Consequential loss is considered an indirect
loss (as compared to losses from the direct
damage). Direct damages would be covered under different types of insurance, such as
property/casual or fire insurance, but the firm
still incurs the costs of lost operations.

Q1 

i). Commerce tries to satisfy increasing human wants

Human wants are never ending. They can be classified as 'Basic wants' and 'Secondary wants'. Commerce has made distribution and movement of goods possible from one part of the world to the other. Today we can buy anything produced anywhere in the world. This has in turn enabled man to satisfy his innumerable wants and thereby promoting social welfare.

ii). Commerce helps to increase our standard of living

Standard of living refers to quality of life enjoyed by the members of a society. When man consumes more products his standard of living improves. To consume a variety of goods he must be able to secure them first. Commerce helps us to get what we want at right time, right place and at right price and thus helps in improving our standard of living.

iii). Commerce links producers and consumers

Production is meant for ultimate consumption. Commerce makes possible to link producers and consumers through retailers and wholesalers and also through the aids to trade. Consumers get information about different goods through advertisements and salesmanship. The manufacturers are regularly informed about the likes and dislikes of the consumers through marketing research. Thus commerce creates contact between the centers of production and consumption and links them.

iv). Commerce generates employment opportunities

The growth of commerce, industry and trade bring about the growth of agencies of trade such as banking, transport, warehousing, advertising, etc. These agencies need people to look after their functioning. Increase in production results in increasing demand, which further results in boosting employment opportunities. Thus development of commerce generates more and more employment opportunities for millions of people in a country.

v) Commerce increases national income and wealth

When production increases, national income also increases. In a developed country, manufacturing industries and commerce together accounts for nearly 80% of total national income. It also helps to earn foreign exchange by way of exports and duties levied on imports. Thus, commerce increases the national income and wealth of a nation.

No (11) Nature figures prominently in Frost’s poetry, and his poems usually include a moment of interaction or encounter between a human speaker and a natural subject or phenomenon. These encounters culminate in profound realizations or revelations, which have significant consequences for the speakers. Actively engaging with nature—whether through manual labor or exploration—has a variety of results, including self-knowledge, deeper understanding of the human condition, and increased insight into the metaphysical world. Frost’s earlier work focuses on the act of discovery and demonstrates how being engaged with nature leads to growth and knowledge. For instance, a day of harvesting fruit leads to a new understanding of life’s final sleep, or death, in “After Apple-Picking” (1915). Mid-career, however, Frost used encounters in nature to comment on the human condition. In his later works, experiencing nature provided access to the universal, the supernatural, and the divine, even as the poems themselves became increasingly focused on aging and mortality.

No (5) Mama is the most nurturing character in the play, and she constantly reminds Walter that all she has ever wanted is to make her children happy and provide for them.

Mama respects Beneatha’s assessment of George Murchison as being arrogant and self- centered, telling her daughter not to waste time with such a “fool.” Mama loves Travis, her grandchild, and hopes their new house will have a big yard in which he can play. She is also very fond, though in a different way, of her plant, which she tries to nurture throughout the play.

In the poem,there is a conflict of cultures between the ancient native life and European imperialism.the cultures symbolically represented by piano and drums respectively.African culture is depicted as simple and natural. Though,it is characterized by mysteries which are understandable. It is unlike the European culture identified with modernity,sophisticated but complicated. African culture is portrayed as attractive for its innocence and simplicity.on the other hand, with phrases like"waiting","solo-speaking" and "tear-furrowed". the impression is given that European culture has several shortcomings.However,we are told that it is "coaxing"as the music from the piano moves in different tonal directions,which suggest some form of attraction.for the poet,it is a culture difficult to understand.

Thou art more lovely and more temperate: Rough winds do shake the darling buds of May, And Summer’s lease hath all too short a date: Sometime too hot the eye of heaven shines, And oft’ is his gold complexion dimm’d; And every fair from fair sometime declines, By chance or nature’s changing course untrimm’d: But thy eternal Summer shall not fade Nor lose possession of that fair thou owest; Nor shall Death brag thou wanderest in his shade, When in eternal lines to time thou growest: So long as men can breathe, or eyes can see, So long lives this, and this gives life to thee.

The play revolves mostly around Aloho, a naïve and jobless university undergraduate who is desperately searching for a job. She meets Ochuole, a notorious old school mate of hers who is the Chief Administrative Officer at the Ministry of External Relations. Ochuole offers to help her secure a job by speaking with the Honourable Minister of External Relations, Chief Ade Haladu-Amaka on her behalf. Aloho is offered a job as one of Chief Ade Haladu-Amaka’s protocol officers. However, she does not know that Ochuole is actually being used by the Chief to perpetrate criminal activities especially drug trafficking. Madam Hoha’s hotel is the hideout for these criminal activities. Chief Ade Haladu-Amaka gives Aloho a package containing hard drugs to deliver in the United States of America. Aloho unknowingly accepts the package and gets arrested at the airport by drug law enforcement officers. Chief Ade Haladu-Amaka bribes the judge and the prosecutors to set Aloho free. Upon Aloho’s release from detention, she discovers she is pregnant for Chief Ade Haladu-Amaka. She makes futile attempts to abort the pregnancy and eventually dies while giving birth to the child. Meanwhile, a honest police officer, ACP Yakubu initiates investigations into allegations of embezzlement of the sum of One point two billion naira embezzled by Chief Ade Haladu Amaka. Ayo, a clerk in the office of Chief provides necessary documents to the police to unravel the crime after receiving a bribe. Ogeyi, Aloho’s friend seeks justice by reporting Chief to the police. Justice prevails in the end as all the corrupt characters are punished and made to pay for the crimes committed.

Prepaid expenses are future expenses that have been paid in advance. You can think of prepaid expenses as costs that have been paid but have not yet been used up or have not yet expired. The amount of prepaid expenses that have not yet expired are reported on a company's balance sheet as an asset.

(2e)
An accrued expense is an accounting expense recognized in the books before it is paid for. It is a liability, and is usually current. These expenses are typically periodic and documented on a company's balance sheet due to the high probability that they will be collected.

3a) Source document is the original record containing the details to substantiate a transaction entered in an accounting system. For example, a company's source document for the recording of merchandise purchased is the supplier's invoice supported by the company's purchase order and receiving ticket.

(2b) At level 6 where total utility is 31. This is when
marginal utility is zero and point of satiety is reached

(2c)
draw diagram

(2d)
law of diminishing marginal utility states that as more and
more unit of a commodity is consumed, there is a
tendency for marginal utility ti decrease as total utility
increases

(3a)
Production possibility curve is a graphical representation
which shows how one good can be transformed into
another good by cutting down on the output of first good
and transferring the resources to production

(1a)

Direct taxes = 100 + 120 = 220

Indirect taxes = 80+100+150+90 = 420

(1b)

Recurrent expenditure = 150+200+220+180+70

= 820

(1c)

Total revenue = 860

Indirect tax = 460

% indirect tax = 460/860 x 100 = 53.49%

(1d)

Total revenue = 860

Total expenditure = 1040

Budget deflecit = 180

Budget deflicit because expenditure is higher than the

revenue collected

(3b)
DRAW THE PRODUCTION POSSIBILITY CURVE

(3c)
-Inability to increase the available resources because the
resources are fixed
-Lack of economy in terms of cost of producing at the
point A

(3d)
Production possibility is negatively sloped because to
increase the production of one commodity,a certain unit of
the other commodity must be given up.There is an inverse
relationship in production of the combined goods

(4a)
-Peasant farming:This is the type of farming which is
concerned with the production of food for the farmer and
his family.A peasant farmer cultivates crops and rears
animals in order to produce food for himself and his
family only.The practice requires a small area of
land,while family labour is employed

-Cooperative farming:This is the type of farming in which
famers come together to enable them enjoy some
incentives from government such incentives include
loans,subsidies,inputs such as fertilizer and easy disposal
of their products through organised markets

(4b)
-Provision of credit facilities to peasant farmers
-Provision of farm inputs such as improved varieties of
seed
-Provision of extension services
-Provision of agricultural education
-Provision of storage processing facilities

(5a)
Price elasticity of supply (PES or Es) is a measure used in
economics to show the responsiveness, or elasticity, of the
quantity supplied of a good or service to a change in its
price.

(5b)
(i)In Joint supply two or more commodities are produced
and supplied from one or more sources, while in
competitive supply two or more commodities are supplied
to serve as substitute.

(ii)In joint supply and increase in the production and
supply of one commodities will bring about an increase in
the production and supply of the commodity, whereas in
competitive supply a commodity is supplied for d
satisfaction of a particular want

(5c)
(i)Cost of production: the cost of production normally
leads to elasticity

(ii)Nature of commodity: perishable goods are elastic in
supply due to their nature

(iii)Cost of storage: producers will supply all their
commodities to the market if the cost of storage is high
thereby leading to elasticity

(iv)Market forces: this determines whether supply will
increase or not

(8a)
Gross Domestic product measures the value of total
production attributes to all factors of production that are
located in the territory of a given country.

(8b)
Gross national product:when necessary adjustment for the
the surplus of a nation on its current account with the rest
of the world has been made, the resulting figure is called
the gross national product(GNP)

(8c)
cost of living is the aggregate amount of money which a
person spends to provide himself the need, usually over a
period of one year

(8d)per capital income is obtained by dividing the total
national income by the total population

(8e)standard of living: when per capita income is
calculated, what you get determines whether the standard
of living is high or low. the higher the quotient, the
higher the standard of living, all things being equal.

MATHS SYMBOLS TO BE USE 
__________________

/ means DIVISION

* means multiplication

tita u should know dat.

rais means raise to power

^ means raise to power

sqr rut/ squar rut means square root

----(1) means equation 1

yr means year

f(x-xbar) means x MINUS x BAR as in statistics
which means that MINUS WILL BE ON TOP OF x.
, (Comma) means NEXT LINE, THIS MEANS THAT THE FOLLOWING NUMBER IS UNDER THE
NUMBER IT IS FOLLOWING i.e UNDER. 

It is
usually used during STATISTICS when drawing a
table.
X:1,2,3,4,
FX: 4,6,8,10
FX-Xbar: 10,8,6,4,

DRAW A TABLE WITH X|FX|(FX-Xbar)
The above statement means that:
~For X, it has 1 2 3 4 5 6 under it. which means 1
is under 2, 2 is under 1, 3 is under 2, 4 is under 3
and so on...
~Under FX you have 4, then 6 under 4, then 8g
under 6, then 10 under 8, then 12 under 10.....
~Under FX-Xbar you have 10, then 8 under 10,
then 6 under 8, then 4 under 6, then 2 under 4,
then 1 under 2....


IN A CLEARER WAY:

→ comma means NEXT LINE(e.g)
x : 1,2,3
fx : 4,5,6
fx-xbar : 10,8,6,4
x|fx |fx-x¯¯|
1| 4 | 10 |
2| 6 | 8 |
3| 8 | 6 |
4| 10| 4 |

Class interval:
60-64,65-69,70-74,75-79,80-84,85-89,90-94,95-99.
X: 62,67,72,77,82,87,92,97.
F: 2,3,6,11,8,7,2,1.
FX: 124,201,432,847,656,609,184,97.
F(x-x bar)2:
561.12,414.18,273.36,33.66,84.48,476.42,351.12,333.06


MEANING OF THE ABOVE EXPRESSION:

Bar means Minus on top of d number or Variable
and comma means next line which means each of
them are unda. Eg 60-64 is unda Class interval,
then 65-69 is unda 60-64,etc .So comma means
unda.


NOTE THAT WHEN U SEE SOMETHING LIKE THE
ABOVE TWO EXAMPLES, U WILL NEED TO DRAW A
TABLE..


YOU NEED TO KNOW THESE ALSO:
MATHS CODES:

1) ,(comma) means next line.
(e.g)
x : 1,2,3

fx : 4,5,6

fx-xbar : 7,8,9

x|fx |x¯¯|
1| 4 | 7 |
2| 5 | 8 |
3| 6 | 9 |
2)*=multiplication sign. y

3)^ = Riase to pwer

4)P also means raised to power eg 10P6 means 10 raised to power six.

5)log3(base 4) ..Note:the base must be SUBSCRIPT .

6)x bar = mean symbol(x¯¯)

-SECTION A

Q3ai) Habitat:- This is defined as the place where an organism lives. Its a place that is suitable to the way of life of an organism. For example, the habitat of a fish is the water which it lives in. Habitat may be small or large. 
The types of habitat are : Aquatic, Terrestial and Artoreal habitat. 

aii) The 3 role of Decomposersbr /> - They help to decompose plant remains into simple forms. 
- They breakdown carbon tied up in large carbohydrate molecules and other minerals contained in dead animal bodies. 
- As decomposers feed from the dead animals, they breakdown the organic compounds into simple nutrients. 

3b) Energy flow in fresh water habitat. 
The ultimate source of energy is sunlight, so the energy flows to the primary producers which are the photosynthetic planktons that traps the energy from the sun and produces it's food through photosynthesis, then it flows to the primary consumers ( Consumer planktons ). Then the energy is transferred to the next energy level when the consumer planktons are eaten by the Secondary Consumers ( small fishes ), and the energy flows lastly to the Tertiary Consumers that is the Big Fishes

Sunlight - - > Photosynthetic Planktons ( primary producers ) - - > Consumer Planktons ( primary consumers ) - - > Small Fish ( Secondary Consumers ) - - > Big fish ( Tertiary Consumers )

C.i) Harmful effects of Micro-organisms. 
- They cause disease. 
- They causes spoilage of food.

________________________

(4b) I. Physical deterioration
ii. Obsolescence
iii. The time factor
iv. Economic factor
v. Inadequacy

4c.)
i. Straight line: This allows an equal amount to be charged as depreciation for each year of expected use of the asset. The basic formulae is 
Cost- Estimated residual value/ number of years of expected use. 
Advantage: it is simple to calculate
ii. It is time oriented

Disadvantage
i. Assumption of equal or constant revenue per year is unrealistic
ii. Might lead to a misleading picture of the financial statement

Cii) Reducing balance: Under this method, the depreciation charged per annum is determined by applying a fixed rate of depreciation on the net book value of the asset at the beginning of each year.

Disadvantage of reducing balance Difficulty in calculating the rate of depreciation -
