MCQs Section QUESTION #4913

Question 3244

A recent study of ancient clay deposits has provided new evidence _____ contributed to the extinction of the dinosaurs and many other creatures some 65 million years ago.

supporting the theory of global forest fires ignited by a meteorite impact that
supporting the theory that global forest fires ignited by a meteorite impact✔️
that supports the theory of global forest fires that were ignited by a meteorite impact and that
in support of the theory that global forest fires were ignited by a meteorite impact and that

Correct Answer Logic:

It clearly expresses the theory: global forest fires ignited by a meteorite impact contributed to the extinction. In option A, the pronoun 'that' ambiguously modifies either 'meteorite impact' or 'fires.' Options C and D add unnecessary 'and that,' creating grammatical awkwardness. Option E changes the meaning by implying the meteorite directly caused the extinction rather than the forest fires.

Nursing QUESTION #9127

Question 3245

A multigravida (G4P3) delivers and immediately develops heavy vaginal bleeding. Uterus is soft, boggy, and non-contracting. Estimated blood loss is 600 mL within 30 minutes. The FIRST-LINE uterotonic drug of choice is:

Ergometrine 0.5 mg IV
Misoprostol 800 mcg sublingual
Oxytocin 10 IU IM or slow IV✔️
Carboprost (PGF₂α) 0.25 mg IM

Correct Answer Logic:

This is Primary Postpartum Hemorrhage (PPH) due to Uterine Atony — the most common cause of PPH (accounts for ~70–80% of cases).

According to WHO guidelines and Pakistan national protocols:

Oxytocin 10 IU IM (or slow IV) = First-line uterotonic for PPH prevention and treatment.
It has rapid onset, minimal side effects, and is heat-stable when refrigerated.
If oxytocin fails: add Ergometrine (avoid in hypertension/cardiac disease), or Carboprost (avoid in asthma).
Misoprostol is used where oxytocin is unavailable (resource-limited settings).

Remember the 4 T's of PPH: Tone (atony), Trauma, Tissue (retained placenta), Thrombin (coagulopathy). Atony is always ruled out first.

Blood loss threshold for PPH: $\geq 500\,\text{mL}$ after vaginal delivery, $\geq 1000\,\text{mL}$ after CS.

Agronomy QUESTION #2064

Question 3246

Zinc deficiency, the most widespread micronutrient deficiency in Pakistan and South Asia, is characterized by:

Dark green, crinkled older leaves with necrotic margins
Interveinal chlorosis and stunting of older leaves due to Zn mobility
Stunted young leaves, shortened internodes (little leaf/khaira disease in rice), interveinal chlorosis on young leaves, and delayed maturity — due to Zn's role in auxin synthesis and enzyme activation✔️
Pale yellow coloration of the entire plant with early senescence

Correct Answer Logic:

Zn deficiency causes little leaf/rosette in fruit trees, khaira disease in rice, and white bud in maize. Young leaves are affected first (Zn is relatively immobile in phloem). Zn activates >300 enzymes, is required for IAA synthesis, RNA polymerase, and ribosome structure. ZnSO₄ (21% Zn) applied at 25 kg/ha corrects deficiency.

Contracts QUESTION #5851

Question 3247

A Farmer agrees to sell his entire upcoming corn crop to a Food Processor. A freak frost destroys the crop before harvest. Is the Farmer's performance excused?

No, because the Farmer assumed the risk of weather.
Yes, under the doctrine of 'Commercial Impracticability'.✔️
No, because the Farmer could buy corn elsewhere to fulfill the contract.
Yes, but only if the contract was for more than $5,000.

Correct Answer Logic:

Under UCC §2-615, delay in delivery or non-delivery is not a breach if performance has been made impracticable by the occurrence of a contingency, like a natural disaster.

Question 3249

Which tribe of Quraish, Hazrat Umar, belonged to?

Banu Hasham
Banu Umayyah
Banu Addi✔️
None of these

Correct Answer Logic:

Hazrat Umar ibn al-Khattab (RA) belonged to the Banu Adiyy clan of the Quraish tribe. He was born around 584 CE in Makkah. Initially, he was a fierce opponent of Islam but converted in 616 CE (6th year of prophethood). His conversion strengthened Islam so much that Muslims began praying openly at the Kaaba. He became the second Caliph and ruled from 634-644 CE, expanding the Islamic empire significantly.

Biology QUESTION #7264

Question 3250

In which one of the following do the male and female gametophytes not have a free-living, independent existence?

Polytrichum
Cedrus✔️
Pteris
Funaria

Correct Answer Logic:

In Cedrus (a gymnosperm), both male gametophyte (pollen grain) and female gametophyte (embryo sac/megagametophyte) are retained within the sporophyte — they are never free-living. In mosses (Polytrichum, Funaria) and ferns (Pteris), the gametophyte (prothallus or plant body) lives freely and independently.

Electrical Engineering QUESTION #2145

Question 3255

A system is described by the transfer function $H(s) = \frac{10}{s^2 + 2s + 10}$. What is the natural frequency $\omega_n$ of this system?

$10\text{ rad/s}$
$\sqrt{10}\text{ rad/s}$✔️
$2\text{ rad/s}$
$5\text{ rad/s}$

Correct Answer Logic:

Comparing with the standard form $\frac{\omega_n^2}{s^2 + 2\zeta\omega_n s + \omega_n^2}$, we see $\omega_n^2 = 10$, so $\omega_n = \sqrt{10}\text{ rad/s}$.

Physics QUESTION #1173

Question 3256

Alpha particles and electrons having the same energy — their associated De Broglie wavelengths are:

Equal
Longer than electrons (alpha has longer wavelength)
Smaller than electrons (alpha has shorter wavelength)✔️
None of these

Correct Answer Logic:

De Broglie wavelength: $\lambda = \frac{h}{\sqrt{2mE}}$. At the same kinetic energy $E$, $\lambda \propto \frac{1}{\sqrt{m}}$. Since $m_\alpha \gg m_e$ (alpha particle is ~7294 times heavier), $\lambda_\alpha \ll \lambda_e$. So alpha particles have a much shorter De Broglie wavelength than electrons at the same energy.

Administration QUESTION #9609

Question 3257

A central bank raises its policy interest rate by 200 basis points. Trace the complete transmission mechanism to a small manufacturing firm's investment decision.

Higher policy rate → higher interbank lending rates → higher commercial lending rates → higher cost of capital for the firm → reduced NPV of investment projects → deferral of capital expenditure✔️
Higher policy rate → lower bond prices → higher equity risk premium → firm issues more equity to avoid expensive debt → diluted ownership but unchanged investment level
Higher policy rate → currency appreciation → cheaper imports → lower input costs for the firm → improved margins offset higher borrowing costs → net investment effect is neutral
Higher policy rate → reduced government borrowing → fiscal surplus → tax cuts → higher consumer demand → firm increases investment to meet demand

Correct Answer Logic:

The monetary policy transmission mechanism: policy rate rise → interbank rate rise → commercial bank lending rates rise (cost of debt increases) → firm's WACC rises → projects that were previously NPV-positive at lower WACC become NPV-negative at higher WACC → marginal investment projects are deferred or cancelled → aggregate capital expenditure falls. This is the investment channel of monetary transmission, and it explains why interest rate policy is the primary tool for managing aggregate demand and investment cycles.

Accounting & Finance QUESTION #1211

Question 3259

In a sales mix decision, the product with the highest contribution margin per unit should be:

Sold exclusively, regardless of customer demand.
Prioritized when resources are constrained.✔️
Avoided to reduce risk.
Discounted to maximize revenue.

Correct Answer Logic:

When resources (such as machine hours or materials) are constrained, products should be ranked by contribution margin per unit of the limiting factor (not just per unit). The product yielding the highest contribution margin per scarce resource should be prioritized to maximize total contribution and profit. Selling exclusively ignores demand and other constraints.
