Accounting & Finance QUESTION #6101

A business creates an allowance for irrecoverable debts at the year end. Which accounting concepts have been applied?

Matching / accruals
Materiality
Prudence
Substance over form

1 and 2
1 and 3✔️
2, 3 and 4
3 and 4 only

Correct Answer Logic:

Option B (1 and 3) is correct.

Matching/Accruals (1): The allowance is recorded in the same period as the related sales revenue.
Prudence (3): The business anticipates a possible future loss and recognises it now, avoiding overstating assets and profits.

Materiality (2) and Substance over form (4) are not specifically relevant here.

Education QUESTION #10891

Question 2

Who is recognised as the founder of discovery learning?

Bruner✔️
Jean Piaget
J.S. Mill
Gardner

Correct Answer Logic:

Jerome Bruner (1915–2016) is the founder of discovery learning — the educational theory that students learn best by actively discovering knowledge through exploration and experimentation rather than passively receiving it. Bruner's concept of the spiral curriculum and his 1961 book The Process of Education established discovery learning. While Piaget's constructivism influenced Bruner, Bruner is specifically credited with developing and promoting discovery learning as a pedagogical approach.

Verbal Reasoning QUESTION #8166

Question 3

Based on the graph of caffeine content in common beverages and drugs, by approximately how many milligrams does the minimum caffeine in a 5-oz cup of drip-brewed coffee exceed the maximum caffeine in a 5-oz cup of cocoa?

(From the FDA graph: drip-brewed coffee ranges roughly 60–180 mg; cocoa ranges roughly 2–20 mg per 5-oz serving.)

$160$ mg
$80$ mg
$60$ mg
$40$ mg✔️

Correct Answer Logic:

From the caffeine bar graph:

The minimum caffeine in drip-brewed coffee (5 oz) is approximately 60 mg.
The maximum caffeine in cocoa (5 oz) is approximately 20 mg.

Difference $= 60 - 20 = \mathbf{40}$ mg.

Answer: approximately 40 milligrams.

Physics QUESTION #7831

Question 4

Two charges +5μC and -5μC separated by 2d. Electric potential at midpoint M:

2kQ/d
kQ/d
None

Correct Answer Logic:

Midpoint: distance from each charge = d. Potential = k(5μ)/d + k(-5μ)/d = 0.

Question 5

Which Surah was recited by the Holy Prophet (PBUH) at the time of Hijrah?

Surah Rehman
Surah Yaseen✔️
Surah Ikhlas
Surah Fateha

Correct Answer Logic:

This is a repeat of question 166. When the Prophet (PBUH) left his home during Hijrah while Quraish surrounded his house intending to kill him, he recited the beginning verses of Surah Yaseen (36:9): 'And We have put before them a barrier and behind them a barrier and covered them, so they do not see.' As he recited these verses and threw dust toward them, Allah blinded them, and he passed through safely. Hazrat Ali (RA) slept in the Prophet's bed that night as a decoy.

Boilers Mechanical Engineering QUESTION #2502

Question 7

The relationship between the shear force $V$ and bending moment $M$ in a beam is:

$V = \frac{d^2M}{dx^2}$
$M = \frac{dV}{dx}$
$V = \frac{dM}{dx}$✔️
$\frac{dV}{dx} = M$

Correct Answer Logic:

From beam equilibrium: $V = dM/dx$. This means the shear force equals the slope of the bending moment diagram. Similarly, $dV/dx = -w$, where $w$ is the distributed load intensity.

Bio-Technology QUESTION #10563

Question 8

Which anaerobic fermentation product is formed by Saccharomyces cerevisiae when pyruvate conversion to ethanol is blocked?

Lactic acid
Butyric acid
Glycerol✔️
2,3-Butanediol

Correct Answer Logic:

When the conversion of pyruvate → acetaldehyde → ethanol is blocked in yeast, the NADH generated in glycolysis must still be reoxidised. S. cerevisiae achieves this by diverting dihydroxyacetone phosphate → glycerol, using glycerol-3-phosphate dehydrogenase. This is exploited industrially with bisulfite addition (which traps acetaldehyde) to direct fermentation toward glycerol production.

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11106

Question 10

Phenetic classification of organisms is based on:

Sexual characters only
Dendrogram based on DNA characteristics
Ancestral lineage of existing organisms
Overall observable (phenotypic) characters of existing organisms✔️

Correct Answer Logic:

Phenetics (numerical taxonomy) classifies organisms based on overall similarity of observable (phenotypic) characters — morphological, physiological, behavioural, biochemical — without regard to evolutionary history or phylogeny. Developed by Sokal and Sneath, it uses multivariate statistical analyses (cluster analysis, phenograms) to group organisms by similarity scores. It contrasts with cladistics (based on shared derived characters/synapomorphies) and phylogenetics (based on evolutionary relationships).

Chemistry QUESTION #7353

Question 11

Which of the following sets of quantum numbers represents an arrangement that is NOT allowed for an electron in an atom?

$n=3,\ \ell=2,\ m=-2,\ s=-\frac{1}{2}$
$n=4,\ \ell=0,\ m=0,\ s=-\frac{1}{2}$
$n=5,\ \ell=3,\ m=0,\ s=+\frac{1}{2}$
$n=3,\ \ell=2,\ m=-3,\ s=-\frac{1}{2}$✔️

Correct Answer Logic:

Rules for valid quantum numbers:

$n \geq 1$
$0 \leq \ell \leq n-1$
$-\ell \leq m \leq +\ell$

In option (4): $n=3, \ell=2$, so $m$ can range from $-2$ to $+2$. But $m = -3$ is outside this range, making it an invalid set. All other options satisfy the rules.

Nursing QUESTION #9308

Question 15

A patient develops pulmonary edema after rapid IV fluid administration. Which position should the nurse place the patient in?

Supine with legs elevated
High Fowler's position (90 degrees) with legs dependent✔️
Left lateral position
Trendelenburg position

Correct Answer Logic:

In acute pulmonary edema, fluid accumulates in the alveoli, causing severe dyspnea and hypoxia. The High Fowler's position (sitting upright at 90°) with legs dangling off the side of the bed is the priority intervention because:

Gravity pulls fluid away from the lungs (reduces venous return to the heart)
Dependent legs act as venous pooling areas (reduces preload)
Upright position maximizes diaphragmatic descent and lung expansion
Improves ventilation-perfusion matching

Additional nursing interventions in pulmonary edema:

High-flow oxygen or CPAP/BiPAP
IV furosemide (diuretic) — reduces fluid overload
IV morphine — reduces anxiety and vasodilates
Stop IV fluids or drastically reduce rate
Cardiac monitoring

Question 16

Which of the following can elevate plasma lithium levels and increase the risk of lithium toxicity?

Moderate exercise
Salt-intake reduction✔️
Smoking cessation
Hypothyroidism

Correct Answer Logic:

Sodium depletion (from low-salt diet, diuretics, vomiting, or excessive sweating) causes the kidney to reabsorb more lithium along with sodium, increasing plasma lithium levels and toxicity risk.

Question 18

Dr. Barnard pioneered a new _____ in heart surgery.

technology
technique✔️
method
None of these

Correct Answer Logic:

Technique is the best answer. A technique refers to a specific skillful way of doing something, especially in a professional or medical context. Technology refers to tools, machinery, or systems — too broad for a surgical approach. Method is more general and less precise than technique in the context of a specific surgical procedure.

Correct Answer: B — technique.

Chemistry QUESTION #7189

Question 20

In a mildly alkaline environment, the thiosulphate ion ($S_{2}O_{3}^{2-}$) undergoes oxidation by $MnO_{4}^{-}$ to produce a species designated as 'A'. What is the oxidation state of sulfur in this resulting product 'A'?

2
4
6✔️

Correct Answer Logic:

In a neutral or weakly alkaline medium, permanganate ($MnO_{4}^{-}$) oxidizes thiosulphate ($S_{2}O_{3}^{2-}$) to sulphate ($SO_{4}^{2-}$). The reaction is:

$8MnO_{4}^{-} + 3S_{2}O_{3}^{2-} + H_{2}O \rightarrow 8MnO_{2} + 6SO_{4}^{2-} + 2OH^{-}$

In the sulphate ion ($SO_{4}^{2-}$), the oxidation state of sulfur is $+6$.
