CISA QUESTION #1769

Question 3922

Which of the following statements about a control self-assessment (CSA) is INCORRECT?

It empowers users to take ownership and accountability for controls
It can replace the need for a traditional audit✔️
It may be used to flag high-risk areas for subsequent review
It lacks the level of independence offered by an external auditor

Correct Answer Logic:

A CSA is a valuable internal tool that promotes user accountability and can identify areas warranting deeper review. However, it is not a substitute for a traditional independent audit, as it does not carry the same level of independence or rigor required for formal audit conclusions.

Biology Zoology Botany QUESTION #1375

Question 3924

Which element is an essential micronutrient for nitrogen fixation in legumes?

Calcium
Manganese
Molybdenum✔️
Magnesium

Correct Answer Logic:

Molybdenum (Mo) is an essential micronutrient required for nitrogen fixation. It is a component of the nitrogenase enzyme complex (specifically the FeMo-cofactor of the MoFe protein) in nitrogen-fixing bacteria such as Rhizobium found in legume root nodules. Without Mo, nitrogenase cannot reduce atmospheric N$_2$ to ammonia.

Disaster Management QUESTION #6538

Question 3927

What makes social protection systems 'shock-responsive' in the context of disaster risk reduction?

They provide more money
They can rapidly scale up to deliver timely assistance to affected populations using existing delivery mechanisms✔️
They only operate during disasters
They replace disaster relief

Correct Answer Logic:

Section 13.5 defines shock-responsive social protection as systems that can rapidly expand assistance during disasters. By using existing targeting, registration, and payment systems, they deliver faster, more efficient disaster response while supporting long-term resilience.

Chemistry QUESTION #7372

Question 3929

A magnetic moment of 2.83 BM is exhibited by which of the following ions? (At. nos: Ti = 22, Cr = 24, Mn = 25, Ni = 28)

$\text{Ti}^{3+}$
$\text{Ni}^{2+}$✔️
$\text{Cr}^{3+}$
$\text{Mn}^{2+}$

Correct Answer Logic:

Formula: $\mu = \sqrt{n(n+2)}$ BM, where $n$ = number of unpaired electrons.

For $\mu = 2.83$ BM: $2.83 = \sqrt{n(n+2)}$ → $n = 2$

Checking $\text{Ni}^{2+}$: Ni (Z=28) = [Ar] 3d⁸ 4s². $\text{Ni}^{2+}$ = [Ar] 3d⁸ → 2 unpaired electrons → $\mu = \sqrt{2 \times 4} = \sqrt{8} \approx 2.83$ BM ✓

Physics QUESTION #7042

Question 3930

The main scale of a screw gauge has a least count of $1 \text{ mm}$. How many circular scale divisions are needed at minimum to measure a $5 \ \mu\text{m}$ diameter wire?

$50$
$200$✔️
$100$
$500$

Correct Answer Logic:

Least Count ($LC$) of a screw gauge is given by: $LC = \frac{\text{Pitch}}{\text{Number of divisions (N)}}$.

Given $LC = 5 \ \mu\text{m} = 5 \times 10^{-6} \text{ m}$ and Pitch $= 1 \text{ mm} = 10^{-3} \text{ m}$.

$N = \frac{10^{-3}}{5 \times 10^{-6}} = \frac{1000}{5} = 200$.

Planning QUESTION #5006

Question 3934

In fiscal impact analysis, what does the multiplier effect measure?

Direct tax revenue only
Total economic impact including indirect effects✔️
Population growth rate
Infrastructure costs

Correct Answer Logic:

The multiplier effect captures how initial spending generates successive rounds of economic activity. For example, a multiplier of 2.5 means each dollar of direct investment generates $2.50 in total regional economic output through indirect (supplier) and induced (household spending) effects.

Suburbanization of middle-class populations
Construction of luxury high-rise apartments

Correct Answer Logic:

Gentrification involves private capital reinvestment rehabilitating deteriorating inner-city neighborhoods, increasing property values, attracting higher-income residents, and displacing original lower-income inhabitants through rising rents and property taxes.

Accounting & Finance QUESTION #9661

Question 3936

Under Single Entry System, an increase in Machinery by Rs. 14,000, an increase in Stocks by Rs. 6,000, a decrease in Debtors by Rs. 2,000, a decrease in Cash by Rs. 1,000, an increase in Creditors by Rs. 1,500, and a decrease in Accrued expenses by Rs. 300 — what is the net change in Owner's Equity before adjusting for drawings and fresh capital?

Rs. 15,800✔️
Rs. 17,200
Rs. 14,200
Rs. 20,800

Correct Answer Logic:

Change in Owner's Equity = Net change in Assets – Net change in Liabilities. Asset changes: +14,000 +6,000 –2,000 –1,000 = +17,000. Liability changes: +1,500 –300 = +1,200. Net change in equity = 17,000 – 1,200 = Rs. 15,800.

Chemistry QUESTION #7159

Question 3937

Which of the following sequences does not accurately reflect the trend of the property mentioned?

$V^{2+} < Cr^{2+} < Mn^{2+} < Fe^{2+}$: paramagnetic behavior✔️
$Ni^{2+} < Co^{2+} < Fe^{2+} < Mn^{2+}$: ionic size
$Co^{3+} < Fe^{3+} < Cr^{3+} < Sc^{3+}$: stability in aqueous solution
$Sc < Ti < Cr < Mn$: number of oxidation states

Correct Answer Logic:

Paramagnetic behavior depends on the number of unpaired electrons.

$V^{2+}$: $[Ar] 3d^{3}$ (3 unpaired)
$Cr^{2+}$: $[Ar] 3d^{4}$ (4 unpaired)
$Mn^{2+}$: $[Ar] 3d^{5}$ (5 unpaired)
$Fe^{2+}$: $[Ar] 3d^{6}$ (4 unpaired)

Since $Fe^{2+}$ has fewer unpaired electrons than $Mn^{2+}$, the increasing order shown in Option 1 is incorrect.

Question 3938

What is the second pillar of Islam?

Zakat
Salat✔️
Hajj
Jihad

Correct Answer Logic:

Salah (Prayer) is the second pillar of Islam after Shahadah (declaration of faith). Muslims are required to perform five daily prayers: Fajr (dawn), Zuhr (noon), Asr (afternoon), Maghrib (sunset), and Isha (night). Salah was made obligatory during the Mi'raj (Night Journey) and is the first thing a Muslim will be questioned about on the Day of Judgment. It is the direct link between the worshipper and Allah, performed facing the Kaaba in Makkah.
