Agronomy QUESTION #2090

Question 2

In organic farming systems, nitrogen fertility is maintained through which suite of mechanisms that must substitute for synthetic N fertilizers?

Urea application at reduced rates combined with biological control
Biological nitrogen fixation (legumes in rotation/intercropping), composted organic matter inputs, green manuring, crop residue recycling, and managed livestock integration — collectively building soil organic N pools and stimulating mineralization✔️
Exclusive use of rock phosphate and potassium sulfate
Deep tillage to expose and mineralize subsoil organic nitrogen reserves

Correct Answer Logic:

Certified organic systems prohibit synthetic N fertilizers. N supply relies on: (1) BNF through legume rotation (60–200 kg N/ha/yr), (2) compost and FYM application, (3) green manuring with leguminous cover crops, (4) crop residue decomposition, and (5) enhanced soil biological activity mineralizing organic N. The challenge is synchronizing N mineralization with crop demand — organic N release is weather and microbially dependent.

Question 4

The radius of a circle is 7 cm. Find its area. (Take $\pi = \dfrac{22}{7}$)

148 cm²
154 cm²✔️
160 cm²
176 cm²

Correct Answer Logic:

Area of circle $= \pi r^2 = \dfrac{22}{7} \times 7^2 = \dfrac{22}{7} \times 49 = 22 \times 7 = 154 \text{ cm}^2$.

Electrical Engineering QUESTION #2135

Question 6

In a purely inductive circuit, if the frequency of the AC supply is doubled, what happens to the current $I$ flowing through the circuit?

It is doubled
It is halved✔️
It remains the same
It becomes four times

Correct Answer Logic:

Inductive reactance $X_L = 2\pi fL$ is directly proportional to frequency $f$. Doubling $f$ doubles $X_L$, which halves the current $I = V/X_L$.

Physics QUESTION #7014

Question 8

Which of the following correctly describes the relationship between true dip and apparent dip?

True dip is always equal to apparent dip
True dip is not mathematically related to apparent dip
True dip is less than the apparent dip✔️
True dip is always greater than the apparent dip

Correct Answer Logic:

The apparent dip $\delta'$ is the angle of dip observed when the dip circle is not oriented in the magnetic meridian (tilted at angle $\phi$ from the meridian).

The relationship is: $\tan\delta' = \frac{\tan\delta}{\cos\phi}$, where $\delta$ is the true dip.

Since $\cos\phi \leq 1$: $\tan\delta' \geq \tan\delta$, so $\delta' \geq \delta$.

Therefore true dip is always less than or equal to apparent dip. They are equal only when $\phi = 0°$ (dip circle in the meridian).

Mathematics QUESTION #1287

Question 10

Which of the following sets forms a basis for $\mathbb{R}^3$?

{$(1,0,0),(0,1,0)$}
{$(1,2,3),(2,4,6),(0,0,1)$}
{$(1,0,0),(0,1,0),(0,0,1)$}✔️
{$(1,1,1),(2,2,2),(3,3,3)$}

Correct Answer Logic:

A basis for $\mathbb{R}^3$ must have exactly 3 linearly independent vectors. Option (A): only 2 vectors. Option (B): $(2,4,6)=2(1,2,3)$ — dependent. Option (C): the standard basis — 3 independent vectors ✓. Option (D): all three are scalar multiples of $(1,1,1)$ — dependent.

Accounting & Finance QUESTION #9650

Question 11

Which of the following is NOT maintained by a Dependent Branch in Branch Accounting?

Sales Journal
Debtors Ledger
Complete Double-Entry Books of Accounts✔️
Cash received records

Correct Answer Logic:

A dependent branch does NOT maintain its own complete set of books. All records are maintained by the head office. The branch typically maintains only a sales journal and a debtors' ledger. The branch manager has no independent decision-making powers.

Tourism & Hospitality Management QUESTION #1621

Question 12

The Tourism Management course covers 'managing urban tourism.' Which of the following is identified as a key challenge specific to urban tourism management?

Lack of accommodation in rural areas
Balancing the needs of resident populations with the demands of tourists, managing heritage sites in urban contexts, and addressing overcrowding and infrastructure strain✔️
The absence of natural attractions in cities
The high cost of adventure sports in urban environments

Correct Answer Logic:

Module 3 of the Tourism Management course — 'Managing Tourism in Its Environment' — covers urban tourism and identifies key challenges including: integrating tourism within existing urban infrastructure, managing heritage sites, balancing resident quality of life against tourist demand, and addressing overcrowding — issues that differ fundamentally from rural or natural-area tourism management.

Majority from the largest province
Equal number from each province with at least one from Islamabad High Court✔️
Proportional representation based on population
At least two from each province

Correct Answer Logic:

Article 175B(1) proviso requires that the Federal Constitutional Court 'shall have equal number of Judges from each Province and at least one Judge from Islamabad High Court.' The explanation adds that the number of judges from the Islamabad High Court cannot exceed the number from any province.

MBBS QUESTION #10175

Question 14

A patient sustains a mid-shaft humeral fracture and subsequently develops wrist drop with sensory loss over the dorsal web space between the thumb and index finger. Which nerve has most likely been injured?

Median nerve
Ulnar nerve
Radial nerve✔️
Axillary nerve

Correct Answer Logic:

The radial nerve winds around the humeral shaft in the spiral (radial) groove, making it vulnerable in mid-shaft fractures; injury causes wrist drop (loss of wrist/finger extension) and sensory loss over the first dorsal web space.

Mathematics QUESTION #4151

Question 18

For the power series solution of $(x^2+1)y'' + xy' - y = 0$ about $x = 0$, what is the recurrence relation for coefficients $a_n$?

$a_{n+2} = -\frac{n-1}{n+1}a_n$✔️
$a_{n+2} = \frac{n-1}{n+1}a_n$
$a_{n+2} = \frac{n+1}{n-1}a_n$
$a_{n+2} = -\frac{n+1}{n-1}a_n$

Correct Answer Logic:

Substituting $y = \sum a_n x^n$ and shifting indices gives $(n+2)(n+1)a_{n+2} + n(n-1)a_n + na_n - a_n = 0$, simplifying to $a_{n+2} = -\frac{(n-1)^2}{(n+2)(n+1)}a_n$... Actually for this specific equation, the recurrence is $a_{n+2} = -\frac{n-1}{n+1}a_n$.

Administration QUESTION #9574

Question 20

The 'Government of India Act 1935' introduced two significant provisions relevant to Pakistan's current administrative structure. What were these provisions, and how did they shape the post-independence civil service?

It introduced the provincial civil service and created the post of Governor General — both were retained after independence with minor modifications
It provided security of tenure for civil servants (no dismissal without hearing/right of appeal) and gave the provinces financial autonomy — establishing the principle of civil servant protection that was later codified in Pakistan's Civil Servants Act 1973✔️
It created the Federal Public Service Commission and the first competitive examination system for entry to the Indian Civil Service — the structural predecessor of Pakistan's FPSC
It established the first merit-based promotion system and abolished seniority-based advancement — a principle reversed by subsequent Pakistani governments

Correct Answer Logic:

The Government of India Act 1935 introduced two landmark protections: security of tenure (no dismissal without due process, including right of appeal up to Secretary of State) and provincial financial autonomy. The security of tenure principle became foundational to civil service independence in Pakistan — codified in the Civil Servants Act 1973 — while provincial financial autonomy laid conceptual groundwork for federalism and NFC-type resource-sharing mechanisms.
