OA Practice

$5 ≠ $7?

In WGU C211 OA, this question leads to Purchasing Power Parity (PPP).

PPP says that identical goods should cost the same across countries once prices are converted into a common currency.

Same goods = same price (after exchange rate adjustment).

If a burger costs:
• $5 in Country A
• $7 equivalent in Country B

Either:
• The exchange rate is misaligned, or
• There are transport costs, taxes, or market distortions.

PPP helps explain:
• Exchange rate movements
• Currency overvaluation or undervaluation
• Long-run price equalization

Example:
If a basket of goods costs $100 in Country A and the same basket costs $150 in Country B, the exchange rate should adjust so that purchasing power equalizes.

C211 Exam Focus:
• PPP = price parity across countries
• Law of One Price foundation
• Long-run exchange rate theory
• Deviations caused by trade barriers, tariffs, transport costs
• Real vs nominal exchange rates

Be careful: The OA may describe short-run differences. PPP is primarily a long-run concept. Temporary price gaps do not automatically violate PPP.

Scan the QR code for exchange rate and PPP scenario practice.

Understand PPP — and international economics questions on C211 become much clearer.

Was plum pudding useless?

Not at all.

In WGU C165 OA, the plum pudding model represents an important stage in the evolution of atomic theory.

Science doesn’t “fail” — it refines.

Thomson’s plum pudding model proposed that electrons were embedded in a positively charged sphere.

Then new evidence (like Rutherford’s gold foil experiment) showed that positive charge and most mass are concentrated in a tiny nucleus.

So the model evolved.

Plum pudding → Nuclear model.

Replacement = progress.

Example:
When experimental evidence contradicts a model, scientists don’t ignore it — they revise the model to better explain observations.

C165 Exam Focus:
• Scientific models change with new evidence
• Plum pudding model (Thomson)
• Gold foil experiment (Rutherford)
• Discovery of the nucleus
• Science is evidence-based and self-correcting

Be careful: The OA may ask whether earlier models were “wrong.” They were incomplete, not useless. Each model explained the data available at the time.

Scan the QR code for atomic theory timelines and experiment breakdowns.

Understand how models evolve — and C165 scientific reasoning questions become much easier.

Too risky?

In WGU C211 OA, weak institutions make economic outcomes unpredictable — and investors hesitate.

Strong institutions create a predictable game.

Institutions include:
• Legal systems
• Property rights
• Contract enforcement
• Regulatory stability

When rules are clear and consistently enforced, investors can estimate risk, protect assets, and plan long-term.

Predictable outcomes → Investors enter.

Unpredictable outcomes → Capital stays away.

Example:
If courts reliably enforce contracts and protect ownership rights, firms are more willing to invest. If rulings are arbitrary or corruption is common, investment drops.

C211 Exam Focus:
• Institutions reduce uncertainty
• Property rights encourage investment
• Rule of law lowers transaction costs
• Predictability increases economic participation
• Weak institutions increase risk premiums

Be careful: The OA may describe political instability, inconsistent enforcement, or corruption. Those signal weak institutional environments — which discourage investment.

Scan the QR code for scenario-based institutional analysis practice.

Understand institutions as the “rules of the game” — and C211 macro and strategy questions become much clearer.

15N + 20N = ?

This is a classic WGU C165 OA net force question.

If forces act in the same direction, you add them.

15N to the right + 20N to the right = 35N to the right.

Same direction = ADD
Opposite direction = SUBTRACT

Net force determines acceleration — not individual forces.

Example:
Two people push a box in the same direction with 15N and 20N. The box experiences a net force of 35N and accelerates in that direction.

But if one pushes 20N right and the other pushes 15N left?

Net force = 5N to the right.

C165 Exam Focus:
• Net force is the vector sum of all forces
• Same direction → add magnitudes
• Opposite direction → subtract magnitudes
• Direction matters
• Net force determines acceleration (Newton’s Second Law)

Be careful: The OA often includes multiple forces in different directions. Always define a positive direction first and account for all forces before calculating the net.

Deception + Self-Interest = ?

In WGU C211 OA, that equation equals Opportunism.

Opportunism is a core concept in transaction cost economics.

It means pursuing self-interest with guile — deception, misrepresentation, or breaking promises to gain advantage.

It’s not just self-interest.

It’s self-interest + deception.

Example:
A supplier promises high-quality materials to win a contract but knowingly delivers lower-quality goods to increase profit.

That’s opportunism.

C211 Exam Focus:
• Opportunism = self-interest with deception
• Linked to transaction cost economics
• Increases monitoring and enforcement costs
• Leads to contracts, safeguards, and governance mechanisms
• Common in uncertain or incomplete contract environments

Be careful: The OA may describe selfish behavior without deception. If there’s no lying, hiding information, or breaking agreements — it’s not opportunism in the TCE sense.

Look for misrepresentation, hidden information, or broken promises.

What holds it up?

If a mug is sitting still on a table, why doesn’t it fall through?

Because the table pushes back.

This is the Normal Force — and it’s a core WGU C165 OA concept.

Gravity pulls the mug downward (weight).

The table exerts an equal upward force — the normal force.

When these forces are equal:

Net force = 0
Acceleration = 0
Object = stationary

Balanced forces don’t mean no forces. They mean equal and opposite forces.

Example:
A book resting on a desk experiences gravity downward and a normal force upward. Same magnitude. Opposite direction. No motion.

C165 Exam Focus:
• Normal force acts perpendicular to a surface
• On a flat surface (no other vertical forces): Normal force = Weight
• Balanced forces → zero acceleration
• Net force determines motion
• Stationary does not mean “no forces present”

Be careful: The OA may include additional vertical forces (like pushing down or lifting up). In those cases, normal force does NOT automatically equal weight. Always account for all vertical forces before concluding they are equal.

Scan the QR code for force-diagram walkthroughs and practice questions.

Master normal force — and Newton’s laws questions become predictable on the C165 OA.

Game over → New game.

In WGU C211 OA, economic transitions aren’t small adjustments — they transform the entire institutional field.

When a country moves from a state-owned system to a market-based system, everything changes.

Old System:
• State-owned enterprises
• Central planning
• Weak or no private property rights

New System:
• Privatization
• Defined property rights
• Market competition

This is not reform at the edges — it’s a structural transformation.

Example:
A formerly state-owned factory is privatized. Ownership transfers to private investors, managers gain profit incentives, and property rights become legally protected. The entire competitive environment shifts.

C211 Exam Focus:
• Transition economies move from command to market systems
• Privatization changes incentives
• Property rights are foundational to market performance
• Institutional change affects firms, industries, and governance
• Field-level transformation, not isolated firm change

Be careful: The OA may describe gradual reform vs full transition. A true transition changes ownership structures and institutional foundations — not just policies.

Starting vs Moving — which needs more force?

This is a classic WGU C165 OA friction question.

The answer: Starting.

Static friction is greater than kinetic friction.

When an object is at rest, static friction resists motion up to a maximum value. You must apply enough force to overcome that maximum static friction to get it moving.

Once the object starts sliding, kinetic friction takes over — and it’s lower.

Example:
Pushing a heavy box across the floor feels hardest at the beginning. Once it’s moving, it becomes easier to keep it sliding.

That’s because:

Static friction > Kinetic friction

C165 Exam Focus:
• Static friction prevents motion
• Kinetic friction acts during motion
• Maximum static friction must be exceeded
• Friction depends on normal force and surface type
• Starting requires more force than maintaining motion

Be careful: The OA may describe a scenario without saying “static” or “kinetic.” If the object hasn’t moved yet → static. If it’s already sliding → kinetic.

Scan the QR code for practice problems and force-diagram walkthroughs.

Understand friction deeply — and C165 force questions become easy points.

3 Pillars — which one controls you?

In WGU C211 OA, institutional theory explains how organizations are shaped by three powerful pressures: regulatory, normative, and cognitive.

Regulatory = rules with teeth.
These are formal laws, regulations, licensing requirements, and government mandates. If you don’t comply, there are penalties.

Normative = social expectations.
Professional standards, industry norms, accreditation bodies, and “how things are done” in your field.

Cognitive = taken-for-granted beliefs.
Shared mindsets, cultural assumptions, and what people see as “normal” or “logical.”

Example: A hospital adopts electronic records.
• Regulatory: Government compliance requirements
• Normative: Medical associations recommending best practices
• Cognitive: Society expects digital efficiency

C211 Exam Focus:
• Know the differences between the three pillars
• Identify real-world examples of each
• Regulatory = formal enforcement
• Normative = professional pressure
• Cognitive = cultural belief systems

Be careful: The OA often disguises normative and cognitive scenarios. If there’s legal enforcement → regulatory. If it’s about professional standards → normative. If it’s about shared beliefs → cognitive.

Scan the QR code for deeper breakdowns and practice scenarios.

Master the three pillars — and institutional theory questions become easy points on the C211 OA.

OA Practice

Falling but NOT speeding up? That’s terminal velocity — and it’s a favorite WGU C165 OA concept.

When an object falls, gravity pulls downward while air resistance pushes upward. At first, gravity is stronger, so the object accelerates.

But as speed increases, air resistance increases too.

Eventually, air resistance equals gravity.

Net force = 0
Acceleration = 0
Velocity = constant

Example: A skydiver jumping from a plane speeds up at first. Once drag force equals weight, they continue falling at a constant speed — not faster, not slower.

C165 Exam Focus:
• Net force determines acceleration (Newton’s Second Law)
• Balanced forces mean zero acceleration
• Zero acceleration ≠ zero velocity
• Terminal velocity occurs when drag = weight
• Constant speed means forces are equal

Be careful: The OA often tests whether you can distinguish between constant velocity and no motion. Balanced forces do NOT mean stopped.

Scan the QR code for practice questions and deeper breakdowns.

Master the force diagrams — and the C165 OA becomes predictable.
