1What is the fundamental economic problem faced by all societies, including small island nations like the Solomon Islands?

A.Scarcity of resources relative to unlimited human wants and needs

B.Excessive government taxation of primary agricultural exports

C.Fluctuations in foreign exchange reserves held by the central bank

D.High inflation caused by reliance on imported petroleum products

Explanation: The core economic problem universal to all economies is scarcity: economic resources (land, labour, capital, enterprise) are finite, whereas human wants and needs are unlimited. This forces individuals, firms, and governments to make choices about resource allocation.

2A farmer in Guadalcanal has one hectare of land. If he grows copra, he earns SBD 12,000 per year. If he grows cocoa, he earns SBD 15,000 per year. If he uses the land to farm vanilla, he earns SBD 18,000 per year. What is the opportunity cost of choosing to farm vanilla?

A.SBD 15,000 per year

B.SBD 12,000 per year

C.SBD 27,000 per year

D.SBD 18,000 per year

Explanation: Opportunity cost is defined as the value of the next best alternative foregone when a decision is made. Given choices of vanilla (SBD 18,000), cocoa (SBD 15,000), and copra (SBD 12,000), if the farmer chooses vanilla, the next best foregone alternative is growing cocoa, valued at SBD 15,000.

3Which of the following points on a Production Possibility Curve (PPC) represents an inefficient allocation of resources?

A.A point located strictly inside the PPC boundary

B.A point located directly on the PPC curve

C.A point located outside the PPC boundary

D.A point where the PPC shifts outward

Explanation: Any point inside the Production Possibility Curve (PPC) indicates that resources are underemployed or used inefficiently, meaning the economy could produce more of one or both goods without incurring an opportunity cost.

4A nation's Production Possibility Curve (PPC) illustrates two goods: Timber Output and Fishery Output. If technological improvements enhance tuna processing equipment in Malaita, how will the PPC change?

A.The PPC will pivot outward along the Fishery axis while remaining unchanged at the Timber axis

B.The entire PPC will shift inward toward the origin

C.The PPC will shift outward parallel along both axes equally

D.The PPC will become a straight downward-sloping line

Explanation: A technological improvement specific to one industry (fisheries) increases maximum potential output for that sector, causing an asymmetrical outward pivot of the PPC along the fishery axis while the intercept on the timber axis stays fixed.

5In a command (planned) economic system, how are the fundamental economic questions ('what', 'how', and 'for whom' to produce) primarily answered?

A.By a central government planning authority through state directive

B.By price signals established through consumer and producer interaction in free markets

C.By traditional customs and inherited social roles passed down through generations

D.By foreign aid donors establishing production quotas

Explanation: In a planned or command economy, the state/government central planning authority makes all decisions regarding resource allocation, production targets, and distribution.

6According to the Law of Demand, holding all other factors constant (ceteris paribus), what happens when the price of a good increases?

A.The quantity demanded of the good decreases

B.The overall demand curve shifts to the right

C.The overall demand curve shifts to the left

D.The quantity demanded of the good increases

Explanation: The Law of Demand states that there is an inverse relationship between price and quantity demanded. An increase in price leads to a movement along the demand curve resulting in a decrease in quantity demanded.

7If household incomes in Honiara increase by 10% and as a result the demand for local cassava increases by 15%, how is cassava classified?

A.A normal good (and luxury good, as income elasticity exceeds +1)

B.An inferior good

C.A Giffen good

D.A substitute good

Explanation: Income Elasticity of Demand (YED) = % Change in Quantity Demanded / % Change in Income = +15% / +10% = +1.5. Since YED > 0, cassava is a normal good; because YED > 1, it is elastic with respect to income (luxury/superior good behavior).

8Suppose the market supply function for canned tuna in Solomon Islands is Qs = -20 + 4P and the market demand function is Qd = 100 - 2P, where P is price in SBD. What is the equilibrium market price and quantity?

A.Price = SBD 20, Quantity = 60 units

B.Price = SBD 15, Quantity = 40 units

C.Price = SBD 25, Quantity = 80 units

D.Price = SBD 10, Quantity = 20 units

Explanation: At equilibrium, Qs = Qd. Thus: -20 + 4P = 100 - 2P => 6P = 120 => P = SBD 20. Substituting P = 20 into Qd = 100 - 2(20) = 60 units (or Qs = -20 + 4(20) = 60 units).

9A destructive tropical cyclone damages coconut plantations across Western Province. How does this event affect the market equilibrium for copra?

A.Supply curve shifts left, increasing equilibrium price and decreasing equilibrium quantity

B.Supply curve shifts right, decreasing equilibrium price and increasing equilibrium quantity

C.Demand curve shifts left, decreasing equilibrium price and quantity

D.Demand curve shifts right, increasing equilibrium price and quantity

Explanation: Natural disasters destroy physical capital and crop yield, reducing production capacity. This causes a decrease in supply (leftward shift of the supply curve), resulting in a higher equilibrium price and a lower equilibrium quantity.

10Consumer surplus is best defined as:

A.The difference between the maximum price consumers are willing to pay and the actual price paid

B.The difference between total government tax revenue and total subsidy expenditure

C.The excess profit earned by firms operating in monopolistic markets

D.The total revenue earned by producers minus variable production costs

Explanation: Consumer surplus measures consumer well-being and is calculated as the difference between the maximum price buyers are willing to pay (represented by the demand curve) and the market clearing price they actually pay.

About the SINF6 Economics Exam

The Solomon Islands National Form Six Examination (SINF6) Economics paper is the national Year 12 economics assessment, administered by MEHRD's National Education Assessment Division and timetabled as part of the Solomon Islands School Certificate Level Two (SISCL2). Candidates sit a single three-hour question-and-answer booklet covering microeconomics, macroeconomics, international trade and finance, and development economics, applied throughout to the Solomon Islands economy. In 2026 the Economics paper is scheduled for Friday 30 October. Economics was among the weaker performing Year 12 subjects in MEHRD's 2024 reporting. The 100 questions on this page are an English-language multiple-choice study adaptation of that syllabus, using Solomon Islands dollar figures and real institutions such as the Central Bank of Solomon Islands; they are a revision aid rather than a simulation of the official paper, which also requires diagrams and extended analysis.

Assessment

Single 3-hour question-and-answer booklet with 10 minutes of reading time. All sections are compulsory and require drawn and labelled diagrams, data interpretation and extended written analysis alongside shorter objective items.

Time Limit

3 hours plus 10 minutes reading time (session 9.00 am – 12.10 pm)

Passing Score

MEHRD does not publish a fixed percentage pass mark. Subject scores feed a Year 12 aggregate; for the 2023 sitting MEHRD reported a minimum aggregate of 265 within an aggregate range of 265–500, and 58.8% of that cohort reached or exceeded it.

Exam Fee

No fee. MEHRD's administrative instruction prohibits schools from charging national examination fees for Year 9, Year 11 and Year 12 candidates. (Ministry of Education and Human Resources Development (MEHRD), National Education Assessment Division (NEAD))

SINF6 Economics Study Tips from Top Performers

1Draw the diagram before you write the explanation. Most extended economics answers are built around a correctly labelled supply and demand, cost curve or AD-AS diagram.

2Learn the elasticity formulas and always state the sign and what it means, since a negative cross elasticity signals complements while a positive one signals substitutes.

3Practise the multiplier in both closed and open forms: 1 divided by (1 minus MPC) for a simple economy, and 1 divided by (MPS plus MPM) once import leakages are included.

4Anchor macro answers in Solomon Islands institutions. Naming the CBSI, the Statutory Reserve Deposit ratio or Bokolo Bills is stronger than writing about a generic central bank.

5For balance of payments questions, list the four current account components separately before summing, so a missing services or secondary income line does not cost you the answer.

6Connect development theory to the local economy. Round log dependence, the subsistence sector and customary land tenure are the examples examiners expect you to use.

Frequently Asked Questions

What is the SINF6 Economics examination?

It is the national Form 6 (Year 12) economics paper administered by MEHRD's National Education Assessment Division, forming part of the Solomon Islands National Form Six School Certificate, now timetabled as the Solomon Islands School Certificate Level Two (SISCL2).
