Question 2

According to Evans et al. (2007), which principle of organizing ensures that each employee receives instructions and is accountable to only one supervisor?

Span of Control
Unity of Command✔️
Division of Labor
Scalar Chain

Correct Answer Logic:

Unity of Command is the organizing principle that each employee should report to and receive instructions from only one supervisor. Dual reporting relationships create confusion and conflict. This principle, originating with Fayol, remains relevant in library organizational design.

Chemistry QUESTION #7351

Question 3

Measurement of an electron's position introduces an uncertainty in momentum equal to $1 \times 10^{-18}$ g cm s$^{-1}$. The uncertainty in electron velocity (mass of electron $= 9 \times 10^{-28}$ g) is:

$1 \times 10^{11}$ cm s$^{-1}$
$1 \times 10^{9}$ cm s$^{-1}$✔️
$1 \times 10^{6}$ cm s$^{-1}$
$1 \times 10^{5}$ cm s$^{-1}$

Correct Answer Logic:

Formula: $\Delta v = \dfrac{\Delta p}{m}$

$\Delta v = \dfrac{1 \times 10^{-18}}{9 \times 10^{-28}} = \dfrac{1}{9} \times 10^{10} \approx 1 \times 10^9$ cm s$^{-1}$

This enormously large uncertainty in velocity illustrates why classical mechanics fails for electrons — they cannot have precisely defined trajectories.

Education QUESTION #10910

Question 7

Through self-evaluation of class teaching, which aspect of teaching is a teacher LEAST able to self-evaluate?

Teaching strategies
Use of AV aids
Preparing textual material✔️
Maintenance of class discipline

Correct Answer Logic:

Preparing textual material is the aspect a teacher is least able to self-evaluate through classroom self-evaluation because it is a preparatory task done before teaching, not directly observable during the lesson. Self-evaluation during or after teaching primarily captures: how strategies worked, how AV aids were used, and how discipline was maintained — all observable in-class events. The quality of textual material preparation requires external review of the materials themselves.

Question 9

Motor vehicles costing $530,000 were depreciated at 10% straight-line instead of the correct 25%. After incorrect entries: Motor vehicles at cost $530,000; Provision for depreciation $53,000. Which journal entries will correct the error?

Debit: Provision for depreciation $79,500 | Credit: Statement of profit or loss $79,500
Debit: Provision for depreciation $132,500 | Credit: Statement of profit or loss $132,500
Debit: Statement of profit or loss $79,500 | Credit: Provision for depreciation $79,500✔️
Debit: Statement of profit or loss $132,500 | Credit: Provision for depreciation $132,500

Correct Answer Logic:

Option C is correct.

Correct depreciation = $530,000 × 25% = $132,500

Already charged = $530,000 × 10% = $53,000

Additional needed = $132,500 − $53,000 = $79,500

Entry: Debit Statement of profit or loss $79,500 | Credit Provision for depreciation $79,500

Question 13

If 10 men can complete a work in 20 days, how long will 8 men take to do the same job at the same rate?

14 days
18 days
20 days
25 days✔️

Correct Answer Logic:

Using the work formula: Men × Days = constant
$10 \times 20 = 8 \times d \Rightarrow d = \dfrac{200}{8} = 25$ days

Education QUESTION #10893

Question 14

IQ stands for:

Inner Quotient
Intelligence Quotient✔️
Intelligence Quartile
Inner Quartile

Correct Answer Logic:

IQ (Intelligence Quotient) is a numerical measure of cognitive ability derived from standardised intelligence tests. Originally: $IQ = \dfrac{\text{Mental Age}}{\text{Chronological Age}} \times 100$. Modern IQ tests (e.g. Wechsler, Stanford-Binet) compare scores to age-group norms, with a mean of 100 and SD of 15. IQ measures reasoning, problem-solving, and abstract thinking. The concept was developed by Alfred Binet and Lewis Terman.

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11070

Question 15

Out of the following codons, which one is NOT a stop codon?

UAA
UAG
GUG✔️
UGA

Correct Answer Logic:

The three stop codons in the standard genetic code are UAA (ochre), UAG (amber), and UGA (opal/umber). They signal termination of translation and are not recognised by any aminoacyl-tRNA (in the standard code). GUG (Guanine-Uracil-Guanine) is a sense codon that codes for valine (Val). It can also occasionally serve as a start codon in prokaryotes (coding for fMet), but it is not a stop codon.

Question 16

Which of the following blood vessels have the lowest blood velocity, with correct reason?

Arteries: Due to thick walls
Capillaries: due to highest overall cross-sectional area✔️
Veins: due to blood flow against gravity
Capillaries: Due to two-way blood flow in capillaries

Correct Answer Logic:

Blood velocity is lowest in capillaries because the total cross-sectional area of all capillaries combined is the greatest, so by continuity, blood slows down significantly.

Tourism & Hospitality Management QUESTION #1593

Question 17

In the context of sustainable tourism, the 'triple bottom line' refers to which three areas of accountability for tourism businesses?

Profit, Marketing, and Operations
Economic viability, Social equity, and Environmental responsibility✔️
Government policy, Industry standards, and NGO oversight
Quality, Safety, and Sustainability

Correct Answer Logic:

The triple bottom line (TBL) framework — covered in the Sustainable Tourism course — holds tourism businesses accountable across three dimensions: Economic viability (financial sustainability), Social equity (community benefit), and Environmental responsibility (ecological protection) — not just financial profit.

Quantitative Reasoning QUESTION #8136

Question 20

Always cautious by nature, she was reluctant to reach conclusions, but once her mind was made up, she was _______ in defending her position.

intransigent✔️
deferential
lax
negligent

Correct Answer Logic:

The sentence contrasts initial reluctance to judge with firm commitment once a decision is made. Intransigent means refusing to change one's position — perfectly describing someone who, once decided, won't back down. 'Resolute' is the synonym pair in the original. 'Deferential' means yielding to others — opposite of holding firm. 'Lax' and 'negligent' both imply carelessness, contradicting the idea of vigorous defense.
