MBBS QUESTION #10149

The median atlantoaxial joint (between the dens of C2 and the anterior arch/transverse ligament of C1) permits rotation of the head and is best classified as which type of synovial joint?

Hinge joint
Pivot joint✔️
Saddle joint
Ball-and-socket joint

Correct Answer Logic:

A pivot joint allows uniaxial rotation of one bone around a central axis formed by another, exactly as the dens of C2 rotates within the ring formed by the atlas and transverse ligament — the mechanism permitting side-to-side head rotation.

Question 2

A Departmental Development Working Party (DDWP) is considering a project costing Rs. 55 million that involves 30% foreign assistance. Which authority has the power to sanction this project?

DDWP since the cost is below Rs. 60 million
CDWP since foreign assistance exceeds 25% of total project cost making DDWP incompetent regardless of cost✔️
ECNEC since any foreign assistance requires its approval
Financial Adviser since it is a development scheme below Rs. 60 million

Correct Answer Logic:

DDWP sanctioning powers are only for local funded projects and projects involving foreign exchange/foreign assistance up to 25% of total cost. Since foreign assistance here is 30% (more than 25%) the approving forum will be CDWP/ECNEC irrespective of the cost of the project.

Question 3

Under the GFR principles enforced by the PAO the principle of 'Prudence' requires that expenditure must not be prima facie more than the occasion demands. A government servant incurs lavish hospitality expenditure at a public function claiming it is within the budget allocation. Which principle is MOST directly violated even if funds are available?

Limitations — because actual expenditure may approach the budget allocation
Prudence — because every government servant must exercise the same vigilance over public funds as a person of ordinary prudence would over their own money✔️
Public Advantage — because the expenditure benefits a section of the community
Propriety — because high standards of financial propriety require formal approval

Correct Answer Logic:

Prudence directly applies: expenditure must not be prima facie more than the occasion demands and every government servant must exercise the same vigilance over public funds as a person of ordinary prudence would over their own money. Lavish hospitality directly contradicts this standard even if within budget.

Question 4

Among the given vitamins, which one is water-soluble?

Vitamin C✔️
Vitamin D
Vitamin E
Vitamin K

Correct Answer Logic:

Vitamins are classified as water-soluble (B-complex and C) or fat-soluble (A, D, E, K). Vitamin C (ascorbic acid) is water-soluble — it dissolves in water and is not stored in the body, so regular dietary intake is required. Vitamins D, E, and K are fat-soluble.

Agronomy QUESTION #2026

Question 5

Irrigation water use efficiency (WUE) is formally defined as:

The ratio of water stored in the root zone to total water applied
The ratio of economic crop yield to the total amount of water consumed by evapotranspiration
$\dfrac{\text{Crop yield (kg/ha)}}{\text{Water applied (mm or m}^3\text{)}}$ expressed as kg per mm or kg per $m^3$✔️
The ratio of water infiltrated to water applied at the field inlet

Correct Answer Logic:

Water use efficiency (WUE) = $\dfrac{\text{Yield (kg/ha)}}{\text{Water applied or consumed (mm)}}$. It measures how efficiently water is converted into economic yield. Maximizing WUE is critical in water-scarce environments and forms the basis of deficit irrigation strategies.

Question 6

Who invented the punch card system for mechanical data processing?

Powers
Pascal
Herman Hollerith✔️
Jacquard

Correct Answer Logic:

Herman Hollerith invented the punched card tabulating machine in 1890 for the US Census. His company later became part of IBM. Joseph Marie Jacquard earlier used punched cards to control looms (1804), but Hollerith's adaptation for data processing is the direct precursor to modern computing punch card systems.

Geology QUESTION #10661

Question 10

In a petroleum exploration scenario, if $\$8{,}000$ was spent on a field and oil sells at $\$40$ per barrel, the minimum number of barrels needed to break even is:

200 barrels✔️
100 barrels
50 barrels
None of these

Correct Answer Logic:

Break-even calculation: $\text{Barrels required} = \dfrac{\text{Total Cost}}{\text{Price per barrel}} = \dfrac{\$8{,}000}{\$40/\text{bbl}} = \mathbf{200 \text{ barrels}}$. The discovery of 2,000 barrels at \$40/bbl generates revenue of \$80,000, which well exceeds the \$8,000 cost. The minimum to recover costs is 200 barrels. This simple break-even concept underpins petroleum economics and investment decision-making.

Mathematics QUESTION #4102

Question 14

The order of element $4$ in the cyclic group $\mathbb{Z}_{18}$ is:

$9$✔️
$4$
$6$
$18$

Correct Answer Logic:

The order of element $k$ in $\mathbb{Z}_n$ is $\dfrac{n}{\gcd(k,n)}$. Here: $\dfrac{18}{\gcd(4,18)}=\dfrac{18}{2}=9$. So element $4$ has order $9$ in $\mathbb{Z}_{18}$.

Verbal Reasoning QUESTION #8064

Question 15

To reproduce an old photograph, a photographer charges $x$ dollars to make a negative, $\frac{3x}{5}$ dollars for each of the first 10 prints, and $\frac{x}{5}$ dollars for each print in excess of 10 prints. If $45 is the total charge to make a negative and 20 prints from an old photograph, what is the value of $x$?

$3$✔️
$3.5$
$4$
$5$

Correct Answer Logic:

Total cost = (negative cost) + (first 10 prints) + (next 10 prints)

Total $= x + 10 \cdot \frac{3x}{5} + 10 \cdot \frac{x}{5} = 45$

$x + \frac{30x}{5} + \frac{10x}{5} = 45$

$x + 6x + 2x = 45$

$9x = 45$

$x = 5$

Therefore $x = 5$ dollars.

Wait, but the marked answer is A (index 0, value 3). Let me verify: if $x = 3$:

Total $= 3 + 10(\frac{9}{5}) + 10(\frac{3}{5}) = 3 + 18 + 6 = 27 \neq 45$

If $x = 5$: Total $= 5 + 10(3) + 10(1) = 5 + 30 + 10 = 45$ ✓

The mathematically correct answer is $x = 5$ (option D, index 3).

Which of the following is the primary site of ATP synthesis during cellular respiration?

Cytoplasm
Outer mitochondrial membrane
Inner mitochondrial membrane✔️
Intermembrane space

The Secretary may take up the case with Additional Finance Secretary (Expenditure)/Finance Secretary or the Minister may take it up with the Finance Minister✔️
The CFAO's view prevails since he is the internal financial control authority

The matter must be referred directly to the Finance Secretary bypassing AFS(E)

Correct Answer Logic:

In case of a difference of opinion with the Financial Adviser the Secretary of the Ministry/Division may take up the case with the Additional Finance Secretary (Expenditure)(AFS-E)/Finance Secretary or the Minister may take it up with the Finance Minister (FM).

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.
