CISA QUESTION #6866

Question 3

In evaluating an organization's audit charter, an auditor finds it grants audit staff access to all systems and data but contains no provisions for auditor confidentiality, document retention, or restrictions on audit evidence use. What is the MOST significant omission?

Incomplete access rights
Lack of provisions protecting confidentiality and appropriate use of sensitive audit evidence✔️
Insufficient authority
Limited scope

Correct Answer Logic:

Audit charters must balance audit access rights with protections for sensitive information obtained during audits. Without confidentiality provisions and restrictions on evidence use, auditors might inappropriately disclose sensitive information, and auditees may withhold information fearing misuse. These provisions protect both the organization and maintain audit effectiveness.

Question 4

Behaviourism as a learning theory is most closely associated with:

Sigmund Freud
B.F. Skinner
J.B. Watson✔️
Johan Wright

Correct Answer Logic:

John B. Watson (1878–1958) is considered the founder of Behaviourism, having formally established it with his 1913 paper 'Psychology as the Behaviourist Views It.' B.F. Skinner later extended behaviourism through Operant Conditioning. Watson argued that psychology should only study observable behaviour, not inner mental states. Sigmund Freud is associated with psychoanalysis; Piaget with cognitive development. Watson founded behaviourism; Skinner extended it.

Physics QUESTION #1041

Question 8

De-Broglie wavelength of an electron in $n=2$ state of hydrogen atom is close to (Bohr radius $= 0.052\ \text{nm}$):

1.67 nm
2.67 nm
0.067 nm
0.67 nm✔️

Correct Answer Logic:

In Bohr model: $2\pi r_n = n\lambda$. For $n=2$: $r_2 = 4r_0 = 4\times0.052 = 0.208\ \text{nm}$. $\lambda = \frac{2\pi r_2}{2} = \pi r_2 = \pi\times0.208\times10^{-9}\approx0.653\ \text{nm}\approx0.67\ \text{nm}$.

Agronomy QUESTION #2093

Question 9

Osmotic adjustment in crops under drought stress is the process by which:

Plants shed their leaves to reduce total transpiring surface area
Cells actively accumulate compatible solutes (proline, glycine betaine, soluble sugars, K⁺) in the cytoplasm and vacuole, lowering osmotic potential and maintaining turgor pressure and metabolic function at lower soil water potentials — enabling continued growth and gas exchange✔️
Roots lose their selective permeability, allowing free water movement into depleted cells
Stomata permanently close to prevent any further water loss

Correct Answer Logic:

Osmotic adjustment (osmoregulation) is an active cellular response to water deficit: solutes accumulate without causing toxicity, lowering $\psi_s$ (osmotic potential) and maintaining positive turgor pressure ($\psi_p = \psi_w - \psi_s$) at lower leaf water potentials. This sustains stomatal opening, photosynthesis, root elongation into dry soil, and metabolic processes — a key drought tolerance mechanism quantified by the Pressure-Volume curve.

English QUESTION #7631

Question 10

Although the Germanic tribes that forcibly migrated into southern and western Europe in the 5th century were _____ converted to Christianity, they retained many of their customs and ways of life.

extremely
ultimately✔️
indispensably
None of these

Correct Answer Logic:

'Ultimately' means 'in the end' or 'eventually', which fits the historical context. The Germanic tribes eventually converted to Christianity over time, not immediately. This word indicates a gradual process of conversion while maintaining their cultural practices.

Quantitative Reasoning QUESTION #8027

Question 11

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.

Dairy Food Science and Technology QUESTION #5918

Question 12

The MSNF (milk solids-not-fat) content of whole cow milk is approximately:

$3.5\%$
$8.5\text{–}9\%$✔️
$12\%$
$1.5\%$

Correct Answer Logic:

MSNF includes all milk solids excluding fat: protein ($\approx 3.2\%$), lactose ($\approx 4.8\%$), minerals ($\approx 0.7\%$) and vitamins. Total MSNF $\approx 8.5\text{–}9\%$. Whole milk TS = fat ($\approx 3.5\text{–}4\%$) + MSNF ($\approx 8.5\text{–}9\%$) $\approx 12\text{–}13\%$.

Question 13

Which of the following is equal to $\frac{1}{4}$ of 0.01 percent?

$0.000025$✔️
$0.00025$
$0.0025$
$0.25$

Correct Answer Logic:

First, convert 0.01 percent to a decimal: $0.01\% = \frac{0.01}{100} = 0.0001$

Now find $\frac{1}{4}$ of this value:

$\frac{1}{4} \times 0.0001 = 0.000025$

Therefore, the answer is $0.000025$.

Math (Module-1) QUESTION #5480

Question 14

In the $xy$-plane, a parabola has vertex $(9, -14)$ and intersects the $x$-axis at two points. If the equation is $y = ax^2 + bx + c$, which of the following could be $a + b + c$?

-23
-19✔️
-14
-12

Correct Answer Logic:

$a+b+c$ is the value of the function at $x=1$ (i.e., $f(1)$). With the vertex at $x=9$, $f(1)$ could be $-19$ depending on the parabola's width.

Chemistry QUESTION #4369

Question 16

Which of the following is true about pressure for an ideal gas at $-273\ °C$?

$P = 1\ atm$
$P = 2\ atm$
$P = 3\ atm$
$P = 0\ atm$✔️

Correct Answer Logic:

$-273\ °C = 0\ K$ (absolute zero). By the ideal gas law $PV = nRT$, at $T = 0\ K$, $P = \frac{nRT}{V} = 0$. At absolute zero, all molecular motion ceases and pressure becomes zero.

Agronomy QUESTION #2097

Question 17

Phosphorus cycling in agricultural soils differs fundamentally from nitrogen cycling because:

Phosphorus has a significant atmospheric reservoir like nitrogen
Phosphorus has no atmospheric reservoir — it cycles exclusively through soil-plant-organic matter pathways, and its availability is controlled by soil pH-dependent precipitation/dissolution reactions and biological mineralization of organic P✔️
Phosphorus is more mobile in soils than nitrogen and prone to leaching in all soil types
Phosphorus transformations are driven by the same microbial guilds (Nitrosomonas, Nitrobacter) that drive nitrogen cycling

Correct Answer Logic:

Unlike N (atmospheric reservoir, gaseous transformations), P cycles in a closed soil-plant system with no atmospheric component. Soil P exists as: soil solution P (plant-available, <1 ppm), labile P (loosely sorbed), non-labile P (strongly sorbed/precipitated), and organic P. Availability is highly pH-dependent: maximum at pH 6.0–6.5; precipitated as Ca-phosphates at high pH and Fe/Al-phosphates at low pH.

Civil / Architecture QUESTION #2353

Question 20

In LRFD design of steel tension members per AISC, the design strength for the fracture limit state (net section rupture) with $\phi_t = 0.75$ is:

$\phi_t P_n = 0.90 F_y A_g$
$\phi_t P_n = 0.75 F_u A_e$✔️
$\phi_t P_n = 0.85 F_y A_g$
$\phi_t P_n = 0.75 F_y A_e$

Correct Answer Logic:

For tension member fracture limit state: $\phi_t P_n = 0.75 F_u A_e$ where $F_u$ is the tensile strength, $A_e$ is the effective net area ($A_e = U \cdot A_n$, with $U$ being the shear lag factor), and $\phi_t = 0.75$. For yielding on the gross section: $\phi_t P_n = 0.90 F_y A_g$. The governing limit state is the lesser value.
