The Constitution of Pakistan QUESTION #9371

Under Article 17(2), if the Federal Government declares a political party to be operating against the sovereignty or integrity of Pakistan, it must refer the matter to the Federal Constitutional Court within:

Immediately
Seven days
Fifteen days✔️
Thirty days

Correct Answer Logic:

Article 17(2) provides that 'the Federal Government shall, within fifteen days of such declaration, refer the matter to the Federal Constitutional Court of Pakistan whose decision on such reference shall be final.'

Preceding business day
Next succeeding day which is not a public holiday✔️

Question 1004

If $\%$ yield is $80\%$ and actual yield is $20\ g$, what will be the theoretical yield?

20 g
25 g✔️
30 g
40 g

Correct Answer Logic:

$\% yield = \dfrac{actual\ yield}{theoretical\ yield} \times 100$. Rearranging: $theoretical\ yield = \dfrac{actual\ yield}{\% yield} \times 100 = \dfrac{20}{80} \times 100 = 25\ g$.

Business, Public administration and Policy QUESTION #10501

Question 1005

In the policy cycle, "agenda setting" refers specifically to:

Identifying problems that decision-makers will act upon✔️
Developing formal policy statements and legislation
Putting approved policies into operational action
Implementing and monitoring government programs

Correct Answer Logic:

Agenda setting is the stage in the policy process where certain problems are identified, defined, and elevated to the attention of policymakers for action. Not all social problems become policy issues — agenda setting is shaped by political actors, interest groups, media, focusing events, and public opinion. It determines what government will decide about.

Maths QUESTION #7941

Question 1006

Which of the following sets of fractions is arranged in descending order?

$\dfrac{3}{4}, \dfrac{7}{9}, \dfrac{6}{7}$
$\dfrac{7}{9}, \dfrac{3}{5}, \dfrac{6}{7}$
$\dfrac{7}{9}, \dfrac{6}{7}, \dfrac{3}{5}$
$\dfrac{6}{7}, \dfrac{7}{9}, \dfrac{3}{5}$✔️

Correct Answer Logic:

Convert each fraction to decimal to compare:

$\dfrac{6}{7} \approx 0.857$
$\dfrac{7}{9} \approx 0.778$
$\dfrac{3}{5} = 0.600$

Descending order: $\dfrac{6}{7} > \dfrac{7}{9} > \dfrac{3}{5}$, which matches option D.

Question 1007

18 is 75% of which number?

24✔️
28
34
32

Correct Answer Logic:

$75\% \times x = 18 \Rightarrow \dfrac{75}{100} \times x = 18 \Rightarrow x = \dfrac{18 \times 100}{75} = 24$

MBBS QUESTION #10257

Question 1008

Glomerular filtration rate (GFR) can be estimated using the renal clearance of a substance that is freely filtered and neither reabsorbed nor secreted, such as inulin: $C = \dfrac{U \times V}{P}$. If urine inulin concentration is 100 mg/dL, urine flow rate is 1.2 mL/min, and plasma inulin concentration is 1 mg/dL, what is the calculated GFR?

12 mL/min
120 mL/min✔️
1.2 mL/min
1200 mL/min

Correct Answer Logic:

$C = \dfrac{(100\ \text{mg/dL}) \times (1.2\ \text{mL/min})}{1\ \text{mg/dL}} = 120\ \text{mL/min}$, close to the normal GFR of approximately 125 mL/min — illustrating why inulin clearance is considered the gold-standard measurement of GFR.

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11090

Question 1009

Among the following soil types, which is the least porous?

Loamy soil
Clayey soil✔️
Silty soil
Peaty soil

Correct Answer Logic:

Clayey soil has the least porosity because clay particles are extremely fine (<0.002 mm) and pack tightly together, leaving minimal air space. Despite having high water-holding capacity, clay has very low macro-porosity (large air-filled pores) and extremely low hydraulic conductivity, making it poorly drained and compacted. Loamy soil (optimal mix of sand, silt, clay) has good porosity; peaty soil (organic matter) has high porosity and water retention; silty soil has intermediate porosity.

Question 1010

Within what temperature range should total parenteral nutrition (TPN) solutions be stored to maintain stability and prevent microbial growth?

$1^\circ\text{C}$ and $4^\circ\text{C}$
$2^\circ\text{C}$ and $8^\circ\text{C}$✔️
$15^\circ\text{C}$ and $20^\circ\text{C}$
$25^\circ\text{C}$ and $35^\circ\text{C}$

Correct Answer Logic:

TPN solutions should be stored refrigerated between $2^\circ\text{C}$ and $8^\circ\text{C}$ according to guidelines, but practically $1^\circ\text{C}$–$4^\circ\text{C}$ is the accepted optimal refrigeration range for these preparations.

MBBS QUESTION #10295

Question 1011

The mid-cycle luteinizing hormone (LH) surge, which triggers ovulation, is a striking example of positive feedback in endocrinology. This surge is triggered by:

Sustained negative feedback of estrogen on the hypothalamic-pituitary axis throughout the cycle
A sustained high level of estrogen from the maturing dominant follicle switching from negative to positive feedback on GnRH/LH secretion✔️
A sudden fall in progesterone levels
Direct stimulatory feedback from inhibin on the pituitary

Correct Answer Logic:

Throughout most of the follicular phase, rising estrogen exerts negative feedback on gonadotropin secretion; however, once estrogen reaches a high, sustained level from the dominant follicle, its feedback effect switches to positive, triggering the surge of GnRH and LH that precipitates ovulation — one of the few examples of physiological positive feedback.

A-IV, B-II, C-I, D-III
A-II, B-I, C-IV, D-III✔️
A-II, B-I, C-III, D-IV

Correct Answer Logic:

XeO$_3$: 3 bond pairs + 1 lone pair → sp$^3$, pyramidal (II). XeF$_2$: 2 bond pairs + 3 lone pairs → sp$^3$d, linear (I). XeOF$_4$: 5 bond pairs + 1 lone pair → sp$^3$d$^2$, square pyramidal (IV). XeF$_6$: 6 bond pairs + 1 lone pair → sp$^3$d$^3$, distorted octahedral (III). Matching: A-II, B-I, C-IV, D-III.

Geology QUESTION #10629

Question 1015

Among the following rock types, which would most likely serve as the best petroleum reservoir?

Granite
Shale
Sandstone✔️
Rock salt

Correct Answer Logic:

Sandstone is the most common and effective petroleum reservoir rock because it has high porosity (spaces between grains to store hydrocarbons) and high permeability (interconnected pores allowing fluid flow). Granite is crystalline with negligible primary porosity; shale has very low permeability (acts as a seal/source); and rock salt is impermeable and is used as a cap rock or creates diapir traps.

Question 1016

In addressing the gap between DRR policy and implementation, what represents the most critical missing link?

More policies
Operational frameworks with clear responsibilities, adequate resources, technical capacity, and accountability mechanisms✔️
Better documentation
International expertise

Correct Answer Logic:

Section 1.4 identifies gaps including weak integration, limited capacity, and insufficient financing. Bridging policy-implementation gaps requires translating strategic goals into operational plans with assigned responsibilities, allocated resources, capacity building, and accountability systems.

Question 1019

What is the term for the process by which a caterpillar becomes a butterfly?

Fragmentation
Budding
Metamorphosis✔️
None of these

Correct Answer Logic:

Metamorphosis is the biological process of transformation from an immature larval stage (caterpillar) to a mature adult form (butterfly). In complete metamorphosis (holometabolism), the four stages are egg, larva (caterpillar), pupa (chrysalis), and adult (imago). Fragmentation and budding are asexual reproduction strategies in simpler organisms.

Agronomy QUESTION #2018

Question 1020

Minimum tillage is advocated in modern agronomy primarily because it:

Increases soil compaction which improves root anchorage
Reduces soil erosion, preserves organic matter, lowers fuel costs, and maintains soil biotic activity✔️
Completely eliminates the need for herbicide application
Increases soil bulk density to improve water retention

Correct Answer Logic:

Minimum tillage (conservation tillage) reduces the number and intensity of tillage operations. This conserves soil structure, reduces erosion, maintains soil organic matter and microbial activity, and significantly reduces labor and fuel costs — central to sustainable crop production.
