The Constitution of Pakistan QUESTION #9343
Question 4021
Which Article states that the validity of the President's election 'shall not be called in question by or before any court or other authority'?
  • Article 44
  • Article 47
  • Article 41(6)βœ”οΈ
  • Article 48(2)
Correct Answer Logic:
Article 41(6) explicitly ousts the jurisdiction of all courts and other authorities to question the validity of the President's election. This is a constitutional exclusion clause, distinct from the general principle of judicial review.

Electronics Engineering QUESTION #11705
Question 4024
A microprocessor-based system uses memory-mapped I/O. The advantage over isolated (port-mapped) I/O is:
  • Faster I/O access due to dedicated instructions
  • I/O devices can be accessed using the full instruction set including indirect addressingβœ”οΈ
  • No address decoding logic is required
  • I/O uses a separate address space, reducing conflicts
Correct Answer Logic:
In memory-mapped I/O, peripherals share the same address space as memory, so the CPU can use its complete instruction set (MOV, AND, OR, bit manipulation, indirect addressing) to access devices. In isolated I/O, only special IN/OUT instructions can access peripherals. Memory-mapped I/O simplifies programming but reduces available RAM address space.

Nursing QUESTION #9241
Question 4028
A Head Nurse notes a patient's pulmonary artery wedge pressure (PAWP) is \(22 \text{ mmHg}\). What does this MOST likely indicate in the context of a hypotensive ICU patient?
  • Hypovolemia β€” fluid resuscitation is needed
  • Pulmonary arterial hypertension
  • Left ventricular failure with pulmonary congestionβœ”οΈ
  • Right ventricular failure β€” start inhaled nitric oxide
Correct Answer Logic:
Correct Answer: C β€” Left ventricular failure with pulmonary congestion

PAWP (Pulmonary Artery Wedge Pressure) Interpretation:
PAWPInterpretation
\(< 8 \text{ mmHg}\)Hypovolemia β€” aggressive fluid resuscitation
\(8 - 12 \text{ mmHg}\)Normal
\(12 - 18 \text{ mmHg}\)Mild-moderate elevation β€” monitor
\(> 18 \text{ mmHg}\)LV failure / pulmonary congestion
\(> 25 \text{ mmHg}\)Severe LV failure / cardiogenic pulmonary edema
PAWP (also called PCWP) reflects left atrial pressure and left ventricular end-diastolic pressure (preload). PAWP \(= 22 \text{ mmHg}\) indicates fluid overload or LV failure. Hypotension with elevated PAWP = cardiogenic shock. Management: diuretics, inotropes (dobutamine), vasopressors.

Question 4029
Which technique is most effective for reducing urban heat island effect?
  • Increasing building density
  • Expanding asphalt surfaces
  • Green infrastructure and tree plantingβœ”οΈ
  • Removing vegetation
Correct Answer Logic:
Green infrastructure (green roofs, urban forests, parks) reduces urban heat island effect through evapotranspiration, shading, and lower surface temperatures compared to concrete and asphalt.

Question 4030
What leads to the formation of the canal system in sponges (Porifera)?
  • Inner wall foldingβœ”οΈ
  • Gastro-vascular system
  • Reproduction
  • Porous walls
Correct Answer Logic:
The canal system in sponges develops from the folding of the inner wall (choanocyte layer). As the sponge body wall folds inward, it increases the surface area of choanocytes (collar cells) that line the canals and chambers, maximising water filtration and feeding efficiency. The three canal systems (asconoid, syconoid, leuconoid) represent increasing degrees of wall folding. The porous walls (ostia) allow water entry, but the canal system architecture itself results from inner wall folding.

Chemistry QUESTION #5584
Question 4031
In the Lucas test, which alcohol reacts the fastest and by which mechanism?
  • Secondary alcohol by $S_N1$
  • Tertiary alcohol by $S_N1$βœ”οΈ
  • Secondary alcohol by $S_N2$
  • Tertiary alcohol by $S_N2$
Correct Answer Logic:
Lucas reagent is $ZnCl_2$/conc. HCl. The reaction involves formation of a carbocation ($S_N1$). Tertiary alcohols form the most stable tertiary carbocations, so they react immediately (solution turns turbid at once). Secondary alcohols react slowly, and primary alcohols require heating. The mechanism for tertiary (and secondary) alcohols is $S_N1$.

Library Sciences QUESTION #1518
Question 4032
A 'trade bibliography' such as Books in Print serves which primary function?
  • Listing all manuscripts held in national archives
  • Identifying and verifying books that are currently available for purchaseβœ”οΈ
  • Providing biographical data about authors
  • Indexing journal articles in a subject field
Correct Answer Logic:
Trade bibliographies like Books in Print list books currently available for purchase from publishers and booksellers. They are essential tools for acquisitions librarians, booksellers, and anyone verifying the commercial availability of a title.

  • Munkir and Nakeer (AS)βœ”οΈ
  • Hazrat Jibrael (AS)
  • Hazrat Israfeel (AS)
  • Hazrat Mikael (AS)
Correct Answer Logic:
Munkir and Nakeer are the angels of the grave.

Chemistry QUESTION #7349
Question 4034
The energy of the second Bohr orbit of hydrogen atom is \(-328\) kJ/mol. Based on this, the energy of the fourth Bohr orbit will be:
  • \(-41\) kJ/mol
  • \(-1312\) kJ/mol
  • \(-164\) kJ/mol
  • \(-82\) kJ/molβœ”οΈ
Correct Answer Logic:
Bohr's energy formula: \(E_n = \dfrac{E_1}{n^2}\)

Given \(E_2 = -328\) kJ/mol, so \(E_1 = -328 imes 4 = -1312\) kJ/mol.

\(E_4 = \dfrac{-1312}{16} = -82\) kJ/mol

Key point: as \(n\) increases, energy becomes less negative β€” outer orbits are less tightly bound.

Question 4035
Which key combination pastes content from the clipboard?
  • Ctrl + P
  • Ctrl + Vβœ”οΈ
  • Ctrl + Shift + V
  • Alt + V
Correct Answer Logic:
Ctrl+V pastes the content from the clipboard into the current location in an application. The universal clipboard shortcuts: Ctrl+C = Copy, Ctrl+X = Cut, Ctrl+V = Paste. In some applications, Ctrl+Shift+V pastes without formatting. Ctrl+P is used for Print, not Paste.

  • 3
  • 6βœ”οΈ

Mathematics QUESTION #6940
Question 4037

Find the number of surjective (onto) functions $f$ from $\{1,2,3,\ldots,20\}$ to $\{1,2,3,\ldots,20\}$ such that $f(k)$ is a multiple of 3 whenever $k$ is a multiple of 4.
  • $6^5 \times (15)!$
  • $5! \times 6!$
  • $(15)! \times 6!$βœ”οΈ
  • $5^6 \times 15$
Correct Answer Logic:

Multiples of 4 in $\{1,\ldots,20\}$: $\{4,8,12,16,20\}$ β€” 5 elements. Their images must be multiples of 3 in $\{1,\ldots,20\}$: $\{3,6,9,12,15,18\}$ β€” 6 elements.

Assign the 5 multiples-of-4 to 5 of the 6 multiples-of-3 (injectively, since $f$ is onto): $6 \times 5 \times 4 \times 3 \times 2 = 6!/(6-5)! = 720$... but we need surjection on all 20 elements.

The remaining 15 domain elements map to the remaining 15 codomain elements (after fixing the 5 images above): $(15)!$ ways. But 1 multiple-of-3 is unused by the multiples-of-4, so it must be covered by remaining 15 elements.

Total $= 6! \times (15)! = (15)! \times 6!$

Mathematics QUESTION #11200
Question 4038
An element $x$ of a group $G$ satisfying $x^2 = x$ is called:
  • Involution
  • Idempotentβœ”οΈ
  • Transposition
  • Cycle
Correct Answer Logic:
An element $x$ of a group satisfying $x^2 = x$ is called idempotent. In a group, since we can multiply both sides by $x^{-1}$: $x^2 = x \Rightarrow x = e$ (identity). So the only idempotent element in a group is the identity. An involution satisfies $x^2 = e$.

Question 4039
The enzyme ATP synthase is located on the membranes of the organelle:
  • Nucleus
  • Mitochondriaβœ”οΈ
  • Lysosomes
  • Chloroplast
Correct Answer Logic:
ATP synthase (Complex V) is embedded in the inner mitochondrial membrane. It uses the proton gradient generated by the electron transport chain (chemiosmosis) to synthesize ATP from ADP and inorganic phosphate. It is also found in the thylakoid membrane of chloroplasts during photosynthesis.
