A lighthouse in a busy shipping lane during normal traffic — its guidance signal is available to all ships without depletion
A public park at normal occupancy — all visitors can use it simultaneously without reducing others' enjoyment
A congested public road during peak hours — additional vehicles reduce traffic flow and increase travel time for all existing users✔️
National defence — the protection provided to one citizen does not reduce protection available to others

Correct Answer Logic:

Public goods are non-excludable (cannot prevent use) and non-rival (use by one does not reduce availability for others). Option C describes congestion — when a public road reaches capacity, additional users impose costs on existing users (reduced speed, increased travel time), making the good rival at the margin. This is the concept of 'congestible public goods' or 'club goods,' illustrating that non-rivalry is conditional on usage levels.

Question 2426

An allocation basis for 'Building Rent' in Departmental Accounts would most appropriately be:

Sales revenue ratio
Number of employees

Purchase ratio

Correct Answer Logic:

Building rent is a space-related expense and should logically be allocated based on the floor area each department occupies. This is the 'obvious just ratio' basis described in the FIN611 text for premises-related costs.

Quantitative Reasoning QUESTION #8027

Question 2433

Experienced employers recognize that business students who can _______ different points of view are ultimately more effective as managers than brilliant students who _______ dogmatically to their own formulations.

assimilate .. adhere✔️
discredit .. revert
impose .. refer
disregard .. incline

Correct Answer Logic:

The sentence praises flexibility over rigidity. Assimilate...adhere works best: good managers assimilate (absorb/integrate) multiple viewpoints, whereas rigid students adhere (stick) dogmatically to their own ideas. Other options don't create a meaningful contrast between open-mindedness and closed thinking.

Civil / Architecture QUESTION #2337

Question 2435

According to Darcy's law, the seepage quantity \(Q\) through a soil sample of cross-sectional area \(A\), length \(L\), head difference \(\Delta h\) and permeability \(k\) is:

\(Q = k \cdot A \cdot \dfrac{L}{\Delta h}\)
\(Q = k \cdot \dfrac{\Delta h}{L} \cdot A\)✔️
\(Q = k \cdot \Delta h \cdot L \cdot A\)
\(Q = \dfrac{k \cdot A}{\Delta h \cdot L}\)

Correct Answer Logic:

Darcy's law: \(Q = k \cdot i \cdot A\) where the hydraulic gradient \(i = \dfrac{\Delta h}{L}\). Therefore \(Q = k \cdot \dfrac{\Delta h}{L} \cdot A\). This linear relationship is valid for laminar flow where velocity is directly proportional to hydraulic gradient.

CISA QUESTION #1737

Question 2436

Which type of audit is specifically focused on comparing the attributes of a finished product against its original design specifications?

Process audit
System audit
Compliance audit
Product audit✔️

Correct Answer Logic:

A product audit systematically compares a finished item — including its physical attributes, dimensions, markings, colour, and features — against the design specifications that governed its production. In the context of IS auditing, this type of audit is particularly relevant when certifying custom-built software or reviewing software prior to release from a development organisation, where the auditor must verify that the delivered product matches what was specified.

Law QUESTION #9506

Question 2438

A obtained an injunction ex parte restraining B from constructing a boundary wall. The injunction was obtained on A's affidavit that B had commenced construction overnight. At the return date, evidence shows the affidavit was false — no construction had taken place. The Court vacates the injunction. B seeks compensation. Is B entitled to compensation and through what forum?

B can apply within the same suit under Section 95 CPC for compensation; the Court may award reasonable compensation if it finds the injunction was obtained on insufficient grounds✔️
B must file a separate suit for damages for wrongful injunction
The Court can impose costs but cannot award compensation
B can only obtain compensation through a suit in tort

Correct Answer Logic:

Section 95 CPC specifically allows a Court to award compensation to the defendant in the same suit for obtaining an arrest, attachment, or injunction on insufficient grounds, without requiring a separate suit. The Court has discretion to award an amount it considers reasonable.

Boilers Mechanical Engineering QUESTION #2515

Question 2439

A particle moves along a curve. Its position vector is \(\mathbf{r}(t)\). The velocity is defined as:

The second derivative \(\ddot{\mathbf{r}}\)
The time derivative \(\dot{\mathbf{r}} = \frac{d\mathbf{r}}{dt}\)✔️
The magnitude \(|\mathbf{r}|\) divided by time
The integral of acceleration

Correct Answer Logic:

By definition, velocity of a point P is \(\mathbf{v} = \frac{d\mathbf{r}}{dt}\), the first time derivative of the position vector. Acceleration is the second derivative \(\mathbf{a} = \ddot{\mathbf{r}}\).

Geography QUESTION #1244

Question 2440

The colour of a star is an indication of its:

Size
Distance away
Surface temperature✔️
None of these

Correct Answer Logic:

The colour of a star directly indicates its surface temperature. Cool stars (around 3,000 K) appear red; medium-temperature stars like the Sun (~5,500 K) appear yellow-white; hot stars (30,000+ K) appear blue-white. This is described by Wien's Displacement Law. A star's colour does not directly indicate its size or distance.
