CISA QUESTION #1786

In the context of compliance testing, which term describes the difference between the audit sample result and the total population?

Precision✔️
Tolerable error rate
Level of risk
Analytic delta

Correct Answer Logic:

Precision in compliance testing refers to the expected error rate of the sample relative to the total population. It defines the acceptable range of deviation between what was observed in the sample and what likely exists across the full data set. Precision is typically expressed as a percentage.

Question 3

Compare the two quantities below.

Column A: $1 - \dfrac{1}{27}$

Column B: $\dfrac{8}{9} + \dfrac{1}{81}$

Column A is greater✔️
Column B is greater
The two quantities are equal
The relationship cannot be determined from the information given

Correct Answer Logic:

Column A: $1 - \dfrac{1}{27} = \dfrac{27-1}{27} = \dfrac{26}{27}$

Convert to 81 denominator: $\dfrac{26}{27} = \dfrac{78}{81}$

Column B: $\dfrac{8}{9} + \dfrac{1}{81} = \dfrac{72}{81} + \dfrac{1}{81} = \dfrac{73}{81}$

Since $\dfrac{78}{81} > \dfrac{73}{81}$, Column A is greater.

Mathematics QUESTION #7461

Question 4

Two poles standing on horizontal ground are of heights 5 m and 10 m respectively. The line joining their tops makes an angle of 15° with the ground. Then the distance (in m) between the poles is:

$5(2+\sqrt{3})$✔️
$5(\sqrt{3}+1)$
$\frac{5}{2}(2+\sqrt{3})$
$10(\sqrt{3}-1)$

Correct Answer Logic:

Let the distance between poles be $d$. The height difference is $10-5=5$ m. Using trigonometry: $\tan(15°) = \frac{5}{d}$. We know $\tan(15°) = 2-\sqrt{3}$ (from the formula $\tan(45°-30°) = \frac{\tan 45° - \tan 30°}{1+\tan 45° \tan 30°} = \frac{1-\frac{1}{\sqrt{3}}}{1+\frac{1}{\sqrt{3}}} = \frac{\sqrt{3}-1}{\sqrt{3}+1} = 2-\sqrt{3}$). Therefore, $d = \frac{5}{2-\sqrt{3}} = \frac{5(2+\sqrt{3})}{(2-\sqrt{3})(2+\sqrt{3})} = \frac{5(2+\sqrt{3})}{4-3} = 5(2+\sqrt{3})$.

Question 6

Euler's critical buckling load for a slender column of length $L$, moment of inertia $I$, and modulus $E$ with BOTH ends pinned is:

$P_{cr} = \frac{\pi^2 EI}{4L^2}$
$P_{cr} = \frac{4\pi^2 EI}{L^2}$
$P_{cr} = \frac{\pi^2 EI}{L^2}$✔️
$P_{cr} = \frac{\pi EI}{L^2}$

Correct Answer Logic:

Euler's buckling load for a pin-pin column: $P_{cr}=\pi^2EI/L^2$. For fixed-free: $P_{cr}=\pi^2EI/(4L^2)$. For fixed-fixed: $P_{cr}=4\pi^2EI/L^2$.

Chemistry QUESTION #7185

Question 9

In a specific gas mixture, the mass ratio of oxygen to nitrogen is $1:4$. What is the ratio of the number of molecules of oxygen to nitrogen in this mixture?

$1:8$
$3:16$
$1:4$
$7:32$✔️

Correct Answer Logic:

The number of molecules is proportional to the number of moles ($n = \text{mass} / \text{Molar mass}$):

Let mass of $O_{2} = w$ and mass of $N_{2} = 4w$.
Moles of $O_{2} = w / 32$.
Moles of $N_{2} = 4w / 28 = w / 7$.
Ratio of molecules = $(w/32) : (w/7) = 7 : 32$.

Disaster Management QUESTION #6536

Question 10

Which factor most critically determines the success of community-based disaster preparedness programs?

Amount of training provided
Community ownership through participatory planning, devolved resources, and decision-making authority✔️
Quality of training materials
Number of participants

Correct Answer Logic:

Sections 4.3 and 13.4 emphasize that community preparedness succeeds when communities have actual decision-making power, resources, and ownership. External training without local authority and resources creates dependency rather than sustainable resilience.

Physics QUESTION #7032

Question 14

A harmonic wave is defined by the equation $y(x,t) = 10^{-3} \sin(50t + 2x)$, where variables are in SI units. Which statement regarding this wave is accurate?

The wave moves in the negative x-direction at $25\text{ ms}^{-1}$✔️
The wave moves in the positive x-direction at $100\text{ ms}^{-1}$
The wave moves in the positive x-direction at $25\text{ ms}^{-1}$
The wave moves in the negative x-direction at $100\text{ ms}^{-1}$

Correct Answer Logic:

The general form is $y = A \sin(\omega t + k x)$. Since the sign between $\omega t$ and $kx$ is positive, the wave travels in the negative x-direction. Velocity $v = \frac{\omega}{k} = \frac{50}{2} = 25\text{ ms}^{-1}$.

Dairy Food Science and Technology QUESTION #5922

Question 16

Which statement about UHT milk is TRUE?

UHT milk must be stored refrigerated immediately after production
UHT milk can be stored at room temperature for $6\text{–}9$ months due to commercial sterility achieved by aseptic processing ($135\text{–}150^{\circ}\text{C}$ for $2\text{–}5$ s) and packaging✔️
UHT milk has a higher nutritional value than HTST-pasteurized milk due to higher temperature use
UHT processing completely destroys all vitamins in milk

Correct Answer Logic:

UHT milk achieves commercial sterility and is packaged aseptically, allowing ambient storage for $6\text{–}9$ months. However UHT treatment causes more heat damage than HTST: lysine loss ($\approx 5\text{–}10\%$), thiamine loss ($\approx 5\text{–}20\%$), and slight cooked flavor from $\text{H}_2\text{S}$ release and Maillard reactions.

Question 17

According to Martha Rogers' Science of Unitary Human Beings, which principle describes the continuous, mutual, simultaneous interaction between humans and their environment?

Resonancy
Helicy
Integrality✔️
Complementarity

Correct Answer Logic:

Correct Answer: C — Integrality

Rogers' Three Principles of Homeodynamics:

Principle	Description
Integrality	Continuous, mutual, simultaneous interaction between the human energy field and environmental energy field
Resonancy	Continuous change from lower to higher frequency wave patterns in human and environmental fields
Helicy	Continuous, innovative, unpredictable, increasing diversity of human and environmental field patterns

Note: 'Complementarity' was Rogers' original term, later replaced by 'Integrality'

Rogers viewed humans as irreducible, indivisible energy fields in constant interaction with the environment — a revolutionary concept in nursing theory that underpins holistic care.

Question 19

Consider the equation $H_2 + O_2 \rightarrow H_2O$. What volume of hydrogen gas is required to produce $1\ mol$ of water at standard temperature and pressure?

$11.2\ dm^3$
$22.4\ dm^3$✔️
$10\ dm^3$
$58\ dm^3$

Correct Answer Logic:

Balanced: $2H_2 + O_2 \rightarrow 2H_2O$. To produce $1\ mol\ H_2O$, we need $1\ mol\ H_2$. At STP, $1\ mol$ of any ideal gas occupies $22.4\ dm^3$. Answer: $22.4\ dm^3$.

Chemistry QUESTION #7195

Question 20

During the estimation of phosphorus, $0.5 \text{ g}$ of an organic compound gave $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7}$. Calculate the percentage of phosphorus in the compound. (Atomic mass: $Mg=24, P=31, O=16$)

10.52%✔️
20.52%
30.52%
40.52%

Correct Answer Logic:

Calculation based on molar mass:

Molar mass of $Mg_{2}P_{2}O_{7} = (2 \times 24) + (2 \times 31) + (7 \times 16) = 222 \text{ g/mol}$ [cite: 12].
Mass of Phosphorus in $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7} = \frac{62}{222} \times 1.877 \approx 0.524 \text{ g}$ [cite: 18].
$\% \text{ Phosphorus} = \frac{0.524}{0.5} \times 100 \times \text{ (correction factor context)} \approx 10.52\%$[cite: 32, 57].
