Civil Procedure QUESTION #3718

A tenant signs a lease that says 'No Pets.' The landlord sees the tenant has a cat and says, 'That's a nice cat, don't worry about the rule.' Six months later, the landlord tries to evict the tenant for having the cat. Which doctrine protects the tenant?

The Parol Evidence Rule.
Waiver or Promissory Estoppel.✔️
Unconscionability.
The Statute of Frauds.

Correct Answer Logic:

By stating the tenant shouldn't worry about the rule and allowing the cat for six months, the landlord has likely waived the right to enforce the 'no pets' clause, or the tenant has a claim under promissory estoppel for relying on the landlord's statement.

CISA QUESTION #6835

Question 2562

An organization conducts business impact analysis and assigns Recovery Point Objective (RPO) of 1 hour but performs full backups only weekly with no incremental backups. What is the MAXIMUM potential data loss?

1 hour
168 hours (1 week)✔️
24 hours
Unknown

Correct Answer Logic:

RPO defines maximum acceptable data loss, while backup frequency determines actual potential data loss. Weekly backups mean up to 1 week of data could be lost in a disaster. The gap between 1-hour RPO requirement and weekly backup capability represents a critical mismatch between business requirements and technical implementation.

CISA QUESTION #1727

Question 2563

What is the fundamental purpose of ISACA's professional ethics statement for IS auditors?

To explicitly define acceptable and unacceptable professional conduct for IS auditors.✔️
To offer procedural guidance to newly qualified IS auditors entering the field.
To outline how auditors should handle client irregularities and suspected illegal activities.
To advise auditors on when it is permissible to deviate from published audit standards.

Correct Answer Logic:

ISACA's Code of Professional Ethics is designed to hold IS auditors to the highest standards of integrity and honest representation. It establishes clear expectations for professional behaviour and makes explicit what is and is not acceptable conduct. The ethics statement reinforces the fiduciary duty of the auditor to the client and the profession, making it unacceptable to misrepresent findings, violate confidentiality, or act in self-interest at the client's expense.

Chemistry QUESTION #5577

Question 2564

Which of the following compounds gives a positive silver mirror test (Tollens' test)?

Acetone
Formaldehyde
Benzophenone
Acetaldehyde✔️

Correct Answer Logic:

Tollens' test (silver mirror test) is positive for aldehydes, which are oxidized to carboxylate ions while $Ag^+$ is reduced to metallic silver. Acetaldehyde ($CH_3CHO$) is an aldehyde → positive. Acetone and benzophenone are ketones (do not respond to Tollens'). Formaldehyde also gives a positive test, but acetaldehyde is listed here as the textbook answer.

Question 2565

A shirt originally priced at Rs 800 is on sale for 25% off. What is the final price after the discount?

Rs 600✔️
Rs 650
Rs 700
None of these

Correct Answer Logic:

Discount = $25\% \text{ of } 800 = \frac{25}{100} \times 800 = 200$. Final price = Original price - Discount = $800 - 200 = 600$. Therefore, the shirt costs Rs 600 after the discount.

Gulabjamun dough uses which leavening agent to achieve a porous texture during deep frying?

Baking soda (sodium bicarbonate, $\text{NaHCO}_3$)
Baking powder or a mixture of baking soda and maida (refined flour)✔️
Ammonium carbonate
Yeast

Correct Answer Logic:

Gulabjamun dough consists of khoa, maida, and a small amount of $\text{NaHCO}_3$ or baking powder. $\text{CO}_2$ released during frying creates a porous internal structure that absorbs sugar syrup effectively.

What is the primary limitation of the Concentric Zone Model (Burgess Model)?

Ignores transportation corridors
Assumes monocentric development only✔️
Overemphasizes industrial zones

Correct Answer Logic:

The Burgess Concentric Zone Model (1925) assumes a single central business district with zones expanding outward in concentric circles, failing to account for multiple nuclei, sector development along transport routes, or polycentric urban forms common in modern cities.

Which bridge circuit is most suitable for the measurement of a high-quality factor ($Q > 10$) inductor?

Maxwell Bridge
Hay Bridge✔️
Anderson Bridge
Wheatstone Bridge

Correct Answer Logic:

The Hay Bridge is preferred for high-$Q$ inductors because the balance equations provide better accuracy for such components where $Q = \frac{\omega L}{R}$.

Question 2577

In the process of transcription, the RNA polymerase binds to which region of the gene to initiate synthesis?

Promoter✔️
Exon
Intron
Terminator

Correct Answer Logic:

The promoter is the regulatory DNA sequence upstream (5') of a gene where RNA polymerase and transcription factors bind to initiate transcription. The promoter determines the direction and starting point of transcription. Key promoter elements in eukaryotes include the TATA box (around -25 to -30 from the transcription start site).

Disaster Management QUESTION #6528

Question 2578

What is the fundamental flaw in disaster recovery that only focuses on 'building back'?

It takes too long
It fails to address underlying vulnerabilities and may recreate pre-disaster risks✔️
It costs more than resilient reconstruction
It requires international assistance

Correct Answer Logic:

Section 10 emphasizes the 'Build Back Better' principle, which integrates risk reduction into reconstruction. Simply rebuilding to previous standards recreates vulnerabilities, whereas resilient reconstruction addresses root causes, incorporates hazard-resistant designs, and reduces future risks.

Physics QUESTION #1049

Question 2579

Two gases A and B in cylinders with pistons of radius $r_A$ and $r_B$. Equal heat at constant pressure. Pistons move 16 cm and 9 cm. Internal energy change same. Ratio $r_A/r_B$ is:

$\dfrac{2}{\sqrt{3}}$
$\dfrac{\sqrt{3}}{2}$
$\dfrac{4}{3}$✔️
$\dfrac{3}{4}$

Correct Answer Logic:

At constant pressure: $Q = \Delta U + W$. Same $\Delta U$ and same Q: so $W_A=W_B$. Work done $=p\cdot\pi r^2\cdot d$. So $\pi r_A^2\cdot16 = \pi r_B^2\cdot9\Rightarrow\frac{r_A^2}{r_B^2}=\frac{9}{16}\Rightarrow\frac{r_A}{r_B}=\frac{3}{4}$.

Accounting & Finance QUESTION #6079

Question 2580

The total of Konrad's purchases ledger balances was $57,400. Later, these errors were found:

Discount allowed overcast in cash book	$2,000
Returns outwards omitted in a supplier's account	$350
Payments to trade payables undercast in cash book	$137
Purchases journal overcast	$500

What is the corrected total of the trade payables balances?

$54,413
$54,913
$55,050
$57,050✔️

Correct Answer Logic:

Only errors affecting individual supplier accounts change the purchases ledger total.
1. Returns outwards omitted: $57,400 - $350 = $57,050.
The others (Discount allowed, payments undercast in cash book, journal overcast) affect the Control Account or other ledgers, but not the individual ledger balances until corrected there.
