Question 3022

Choose the word nearly opposite in meaning to "LARCENY"

Appropriation
Peculation
Purloining

Physics QUESTION #7079

Question 3023

Determine the pressure required at the ends of a steel wire (length $10\text{ cm}$) to maintain a constant length when the temperature is increased by $100^{\circ}\text{C}$. (Given: Steel Young's modulus $Y = 2 \times 10^{11}\text{ Nm}^{-2}$ and coefficient of thermal expansion $\alpha = 1.1 \times 10^{-5}\text{ K}^{-1}$)

$2.2 \times 10^{7}\text{ Pa}$
$2.2 \times 10^{6}\text{ Pa}$
$2.2 \times 10^{8}\text{ Pa}$✔️
$2.2 \times 10^{9}\text{ Pa}$

Correct Answer Logic:

The thermal stress required to keep the length constant is given by the formula:

$\text{Stress} = Y \alpha \Delta T$
Substituting the values: $\text{Stress} = (2 \times 10^{11}) \times (1.1 \times 10^{-5}) \times 100$
$\text{Stress} = 2.2 \times 10^{8}\text{ Pa}$

Pressure is equivalent to the stress applied at the ends.

Agronomy QUESTION #2055

Question 3024

The permanent wilting point (PWP) of soil is the moisture content at which:

All gravitational water has drained from the soil macropores
Plants can no longer extract sufficient water from the soil and wilt permanently, corresponding to a soil matric potential of approximately $-1500$ kPa (or $-15$ bar)✔️
Soil moisture equals 50% of field capacity
Surface evaporation exceeds plant transpiration

Correct Answer Logic:

PWP is the soil moisture content at which the remaining water is held so tightly by soil particles (matric potential ≈ −1500 kPa) that roots cannot exert sufficient suction to extract it. Plants wilt permanently — they do not recover even when placed in a humid atmosphere. Plant-available water = FC − PWP.

Nursing QUESTION #9240

Question 3027

A patient receiving Total Parenteral Nutrition (TPN) in the ICU develops sudden onset of confusion, tachycardia, and muscle weakness 48 hours after refeeding. Lab results show: K$^+ = 2.8 \text{ mEq/L}$, PO$_4^{3-} = 0.4 \text{ mmol/L}$, Mg$^{2+} = 0.6 \text{ mmol/L}$. What syndrome is occurring?

Hyperglycemic hyperosmolar state
Refeeding syndrome✔️
Wernicke's encephalopathy
Central pontine myelinolysis

Correct Answer Logic:

Correct Answer: B — Refeeding Syndrome

Refeeding Syndrome occurs when nutrition (especially carbohydrates) is reintroduced after prolonged starvation. The sudden increase in insulin drives intracellular shift of electrolytes, causing:

Electrolyte	Change	Normal Range	Consequence
Phosphate (PO$_4^{3-}$)	↓ Critical	$0.8 - 1.5 \text{ mmol/L}$	Respiratory failure, hemolysis, cardiac arrest
Potassium (K$^+$)	↓ Hypokalemia	$3.5 - 5.0 \text{ mEq/L}$	Arrhythmias, muscle weakness
Magnesium (Mg$^{2+}$)	↓ Hypomagnesemia	$0.8 - 1.0 \text{ mmol/L}$	Arrhythmias, seizures, neuromuscular excitability

Prevention: Start TPN slowly, correct electrolytes before refeeding, monitor daily, supplement thiamine (vitamin B1) prophylactically.

Statistics QUESTION #2007

Question 3030

In the confidence interval for $p_1 - p_2$, with $\hat{p}_1 = 62/100 = 0.62$ and $\hat{p}_2 = 69/150 = 0.46$, the estimated standard error $SE(\hat{p}_1 - \hat{p}_2)$ equals:

$\sqrt{\dfrac{0.62(0.38)}{100} + \dfrac{0.46(0.54)}{150}}$✔️
$\sqrt{\dfrac{0.62(0.38) + 0.46(0.54)}{250}}$
$\dfrac{0.62 - 0.46}{\sqrt{250}}$
$\sqrt{\dfrac{0.54 \times 0.46}{250}}$

Correct Answer Logic:

For independent samples and a confidence interval (not a hypothesis test), the SE is $\sqrt{\dfrac{\hat{p}_1(1-\hat{p}_1)}{n_1} + \dfrac{\hat{p}_2(1-\hat{p}_2)}{n_2}} = \sqrt{\dfrac{0.62 \times 0.38}{100} + \dfrac{0.46 \times 0.54}{150}}$. The pooled estimate is used only for hypothesis testing, not CI construction.

Law QUESTION #9535

Question 3032

A Court recording evidence in a civil suit allows a party to produce a document which is a carbon copy of an original without proving the original's existence or unavailability. The opposing party objects. What should the Court do?

Allow the copy and direct the original to be produced later
Sustain the objection; secondary evidence of a document including carbon copies can only be admitted under the circumstances prescribed in the Evidence Act, such as proving the original is lost, destroyed or in the possession of the opposite party; mere production of a copy without accounting for the original is improper✔️
Allow the carbon copy since all copies are equivalent
Allow the copy since civil Courts have relaxed evidentiary standards

Correct Answer Logic:

Under the Qanun-e-Shahadat Order 1984 (the Pakistani evidence law), secondary evidence of a document is only admissible after the original has been proved to be lost, in the possession of the adverse party, in the custody of a person abroad, or otherwise unavailable. Admission of a copy without establishing the above conditions violates the best evidence rule.

English QUESTION #2743

Question 3034

Identify the ERROR in: 'Neither the manager nor the employees was present.'

manager
nor
employees
was✔️

Correct Answer Logic:

With 'neither...nor', the verb agrees with the subject closest to it. Since 'employees' (plural) is closer, the verb should be 'were', not 'was'.

CISA QUESTION #6846

Question 3035

An IS auditor discovers that security logs are generated but retained for only 7 days due to storage limitations. The organization's incident response procedures require 90 days of log data for investigation. What is the PRIMARY risk?

Inadequate storage capacity
Insufficient log retention prevents effective incident investigation and forensic analysis✔️
Excessive log volume
Complex log management

Correct Answer Logic:

The 83-day gap between log retention (7 days) and investigative requirements (90 days) means most incidents cannot be properly investigated. By the time incidents are detected and investigation begins, critical evidence has been deleted. This severely compromises security monitoring, incident response, and forensic capabilities.

Reading and Writing (Module-1) QUESTION #5398

Question 3037

The following text is from Walt Whitman's 1860 poem "Calamus 24." I HEAR it is charged against me that I seek to destroy institutions; / But really I am neither for nor against institutions / (What indeed have I in common with them?— / Or what with the destruction of them?), / Only I will establish in the Mannahatta [Manhattan] and in every city of These States, inland and seaboard, / And in the fields and woods, and above every keel [ship] little or large, that dents the water, / Without edifices, or rules, or trustees, or any argument, / The institution of the dear love of comrades. Which choice best describes the overall structure of the text?

The speaker questions an increasingly prevalent attitude then summarizes his worldview.
The speaker regrets his isolation from others then predicts a profound change in society.
The speaker concedes his personal shortcomings then boasts of his many achievements.
The speaker addresses a criticism leveled against him then announces a grand ambition of his.✔️

Correct Answer Logic:

The speaker first addresses accusations that he seeks to destroy institutions, then declares his goal to establish 'the institution of the dear love of comrades' everywhere.

Boilers Mechanical Engineering QUESTION #2499

Question 3038

For triaxial principal stresses ordered as $\sigma_1 > \sigma_2 > \sigma_3$, the absolute maximum shear stress is:

$\tau_{max} = \frac{\sigma_1 - \sigma_2}{2}$
$\tau_{max} = \frac{\sigma_2 - \sigma_3}{2}$
$\tau_{max} = \frac{\sigma_1 - \sigma_3}{2}$✔️
$\tau_{max} = \frac{\sigma_1 + \sigma_3}{2}$

Correct Answer Logic:

In triaxial stress state with $\sigma_1 > \sigma_2 > \sigma_3$, the maximum is $\tau_{max}=\tau_{1/3}=(\sigma_1-\sigma_3)/2$.

Boilers Mechanical Engineering QUESTION #2516

Question 3039

In normal-tangential (n-t) coordinates, the acceleration of a particle moving along a curved path with speed $v$ and radius of curvature $\rho$ is:

Only the tangential component $\dot{v}\,\hat{e}_t$
Only the normal component $\frac{v^2}{\rho}\hat{e}_n$
Both $a_t = \dot{v}$ tangentially and $a_n = \frac{v^2}{\rho}$ normally✔️
A single vector directed toward the center of curvature

Correct Answer Logic:

In n-t coordinates: $\mathbf{a}=\dot{v}\hat{e}_t + \frac{v^2}{\rho}\hat{e}_n$. The tangential component $a_t=\dot{v}$ reflects speed change; the normal (centripetal) component $a_n=v^2/\rho$ reflects direction change.
