Geology QUESTION #10659

For shallow near-surface site investigation in engineering geology, the most appropriate geophysical method is:

Gravity surveying
Magnetic surveying
Seismic refraction✔️
None of these

Correct Answer Logic:

Seismic refraction is the preferred method for shallow site investigation (0–30 m depth) because it directly measures P-wave velocity contrasts between soil/rock layers, providing bedrock depth, weathering profile, and rippability assessments. It is cost-effective, non-invasive, and rapid. Gravity and magnetic methods have much lower resolution for shallow targets and are more suited to regional geological mapping or deeper structure investigations.

Nursing QUESTION #9302

Question 3

In medical-surgical nursing, a patient on long-term corticosteroid therapy should be monitored for which of the following complications?

Hypoglycemia
Hyponatremia
Cushing's syndrome features including hyperglycemia, moon face, and osteoporosis✔️
Bradycardia

Correct Answer Logic:

Long-term corticosteroid therapy mimics endogenous excess cortisol, producing iatrogenic Cushing's Syndrome:

System	Effect of Excess Corticosteroids
Metabolic	Hyperglycemia (steroid-induced diabetes)
Appearance	Moon face, buffalo hump, central obesity, striae
Skeletal	Osteoporosis, vertebral fractures
Immune	Immunosuppression — increased infection risk (mask fever!)
Cardiovascular	Hypertension, fluid retention, edema
Electrolytes	Hypokalemia, hypernatremia
GI	Peptic ulcer formation

Critical nursing point: Patients on long-term steroids should never abruptly stop — risk of adrenal crisis (Addisonian crisis). Taper dosage gradually.

Law QUESTION #9476

Question 4

Two suits are pending simultaneously: Suit I filed by A against B in Civil Court Lahore for breach of a contract to sell land, and Suit II filed by B against A in Civil Court Karachi for specific performance of the same contract. Both suits involve the same parties and the same contract. Karachi Court is asked to stay Suit II. What should the Karachi Court do?

Dismiss Suit II outright since only one suit is permissible
Stay Suit II since the matter in issue is directly and substantially in issue in a previously instituted suit between the same parties, and Lahore Court has jurisdiction to grant the relief claimed✔️
Refuse to stay Suit II since it was filed in a different city by a different plaintiff
Transfer both suits to a neutral Court

Correct Answer Logic:

Section 10 CPC mandates that no Court shall proceed with trial of any suit where the matter in issue is also directly and substantially in issue in a previously instituted suit between the same parties pending in any other Court in Pakistan having jurisdiction. Suit I was instituted first; Suit II must be stayed.

Quantitative Reasoning QUESTION #7210

Question 5

Read the following passage and answer the question.

Large-scale housing construction is currently underway in Pataska Forest, the habitat of a sizeable deer population. Since deer tend to feed along forest edges, these animals will be drawn to the areas bordering the new roads being built through the forest to serve the residential developments. Consequently, once residents move in, the number of forest deer struck by vehicles annually will be considerably higher than it was before construction began.

Which of the following is an underlying assumption that the argument depends upon?

The number of deer struck by commercial vehicles will not rise substantially once the housing is occupied.
Deer will be equally attracted to forest edges near new houses as they are to edges alongside roads.
Historically, very few deer have been struck by cars on the existing roads through Pataska Forest.
The development will leave sufficient forest to support a significant deer population.✔️

Correct Answer Logic:

This is a critical reasoning assumption question. The argument concludes that more deer will be hit by cars once the housing is occupied. We must find what the argument must silently assume for its conclusion to hold.

The argument’s logic chain:

Deer feed at forest edges.
New roads create new forest edges.
Therefore, deer will gather near roads → more deer-vehicle collisions.

For this conclusion to be possible, there must still be deer in the forest. If the development destroyed so much forest that the deer population collapsed or disappeared, there would be no deer left to collide with cars. The argument must assume that enough forest survives to sustain a substantial deer population — i.e., Option D.

A — About commercial vehicles; the argument concerns cars from residents, not commercial traffic. Distractor.
B — Compares road edges to house edges; the argument only requires deer near roads, not near houses.
C — Past collision numbers are irrelevant; the argument is about a future increase, not about whether the prior baseline was low or high.

Correct Answer: D. Without a surviving deer population, the conclusion about increased collisions becomes impossible.

Mathematics QUESTION #10985

Question 7

A parallel plate air capacitor has a capacitance C. When it is half filled as show in figure with a dielectric constant $K=5$ , the percentage increase in the capacitance is ________.

66.67
✔️
33.34
400
200

Correct Answer Logic:

Step 1: Initial Capacitance

The initial capacitance of the parallel plate air capacitor is given by:

C = \frac{\varepsilon_0 A}{d}

Step 2: Equivalent Capacitance with Dielectric

When a dielectric of constant $K = 5$ fills half the distance ( $\frac{d}{2}$ ), the system behaves as two capacitors connected in series:

Air-filled portion ( $C_1$ ):

$C_1 = \frac{\varepsilon_0 A}{\frac{d}{2}} = \frac{2\varepsilon_0 A}{d} = 2C$
Dielectric-filled portion ( $C_2$ ):

$C_2 = \frac{K \varepsilon_0 A}{\frac{d}{2}} = \frac{5 \cdot 2\varepsilon_0 A}{d} = 10C$

Using the equivalent series capacitance formula:

\frac{1}{C_{\text{eq}}} = \frac{1}{C_1} + \frac{1}{C_2}

\frac{1}{C_{\text{eq}}} = \frac{1}{2C} + \frac{1}{10C} = \frac{5 + 1}{10C} = \frac{6}{10C} = \frac{3}{5C}

C_{\text{eq}} = \frac{5}{3}C

Step 3: Percentage Increase

\text{Percentage Increase} = \left(\frac{C_{\text{eq}} - C}{C}\right) \times 100\%

\text{Percentage Increase} = \left(\frac{\frac{5}{3}C - C}{C}\right) \times 100\% = \frac{2}{3} \times 100\% \approx 66.67\%

Psychology QUESTION #9833

Question 8

Self-assertive behaviour is an example primarily of:

An abundancy motive
A stimulation motive✔️
A survival motive
A security motive

Correct Answer Logic:

Self-assertion — expressing one's needs, opinions, and boundaries — is driven by a stimulation motive (need for agency, growth, and self-expression). It goes beyond survival needs and reflects higher-order drives for autonomy and impact.

Agronomy QUESTION #2095

Question 16

In cropping systems agronomy, the concept of 'system yield' as opposed to 'crop yield' emphasizes:

Maximizing the yield of the most economically valuable crop in the sequence
The total productivity, profitability, resource use efficiency, and sustainability of the entire sequence of crops grown on the same land over a year or multiple years — recognizing that management of one crop directly affects subsequent crops✔️
The yield of a single crop grown without any rotation or intercropping
The cumulative yield of all crops harvested from a single field in one calendar year

Correct Answer Logic:

System yield integrates the productivity of all component crops over time, accounting for carryover effects: residual nitrogen from legumes, disease/pest carryover, soil structure changes, and water use patterns. A cropping system may sacrifice individual crop yield to maximize system-level sustainability, profitability, and resource use efficiency — the central paradigm shift in modern cropping systems agronomy.

Mathematics QUESTION #7456

Question 18

The distance of the point $(1, 3, -7)$ from the plane passing through the point $(1, -1, -1)$, having normal perpendicular to both the lines $\frac{x-1}{1} = \frac{y+2}{-2} = \frac{z-4}{3}$ and $\frac{x-2}{2} = \frac{y+1}{-1} = \frac{z+7}{-1}$, is:

$\frac{20}{\sqrt{74}}$
$\frac{10}{\sqrt{83}}$
$\frac{5}{\sqrt{83}}$
$\frac{10}{\sqrt{74}}$✔️

Correct Answer Logic:

The direction ratios of the two lines are $(1,-2,3)$ and $(2,-1,-1)$. The normal to the plane is perpendicular to both, so it's their cross product: $\vec{n} = \begin{vmatrix} \hat{i} & \hat{j} & \hat{k} \\ 1 & -2 & 3 \\ 2 & -1 & -1 \end{vmatrix} = \hat{i}(2-(-3)) - \hat{j}(-1-6) + \hat{k}(-1-(-4)) = 5\hat{i} + 7\hat{j} + 3\hat{k}$. The plane equation through $(1,-1,-1)$ with normal $(5,7,3)$ is $5(x-1) + 7(y+1) + 3(z+1) = 0$, which gives $5x+7y+3z+5 = 0$. Distance from $(1,3,-7)$ is $\frac{|5(1)+7(3)+3(-7)+5|}{\sqrt{25+49+9}} = \frac{|5+21-21+5|}{\sqrt{83}} = \frac{10}{\sqrt{83}}$.

Chemistry QUESTION #1072

Question 19

Out of the following complex compounds, which will have minimum conductance in solution?

$[\text{Co(NH}_3)_6]\text{Cl}_3$
$[\text{Co(NH}_3)_5\text{Cl}]\text{Cl}$
$[\text{Co(NH}_3)_3\text{Cl}_3]$✔️
$[\text{Co(NH}_3)_4\text{Cl}_2]\text{Cl}$

Correct Answer Logic:

$[\text{Co(NH}_3)_3\text{Cl}_3]$ is a non-electrolyte — all chlorides are inside the coordination sphere and no ions are released in solution. Minimum conductance means fewest ions in solution. This complex dissociates into 0 ions, giving minimum (zero) ionic conductance.
