Accounting & Finance QUESTION #6136

Question 2

The total of the discount column on the debit side of the cash book had been debited to discount received instead of correctly posted. Which accounts correct this error?

Discount allowed
Discount received
Suspense

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

Correct Answer Logic:

Option B (1 and 2 only) is correct.

The debit side discount column = discounts allowed. Correct entries: Debit discount allowed; Credit discount received. The error debited discount received instead of crediting it. Correction uses discount allowed and discount received only — no suspense needed as both sides of the trial balance are equally affected.

Maths QUESTION #4588

Question 3

If $a:b = 1:2$ and $b:c = 3:4$, find $a:b:c$:

$1:2:4$
$3:6:8$✔️
$1:3:4$
Both B and C

Correct Answer Logic:

Make $b$ equal in both ratios: $a:b = 3:6$ and $b:c = 6:8$. So $a:b:c = 3:6:8$

Nursing QUESTION #9234

Question 4

A Head Nurse notes that an ICU patient's Glasgow Coma Scale (GCS) score is as follows: opens eyes to pain ($E2$), makes incomprehensible sounds ($V2$), flexion withdrawal to pain ($M4$). What is the total GCS score and what does it indicate?

$\text{GCS} = 6$ — severe brain injury, immediate intubation required
$\text{GCS} = 7$ — severe brain injury, intubation strongly indicated
$\text{GCS} = 8$ — severe brain injury, intubation indicated (threshold $\leq 8$)✔️
$\text{GCS} = 9$ — moderate brain injury, close monitoring required

Correct Answer Logic:

Correct Answer: C — GCS = 8

GCS Calculation:
\[\text{GCS} = E + V + M = 2 + 2 + 4 = 8\]

GCS Scoring:

Domain	Response	Score
Eye (E)	Spontaneous	4
	To voice	3
	To pain	2
	None	1
Verbal (V)	Oriented	5
	Confused	4
	Inappropriate words	3
	Incomprehensible sounds	2
	None	1
Motor (M)	Obeys commands	6
	Localizes pain	5
	Withdrawal	4
	Flexion (Decorticate)	3
	Extension (Decerebrate)	2
	None	1

GCS $\leq 8$ = severe brain injury = airway protection threshold — intubation is indicated.

HR and Management QUESTION #6430

Question 8

The concept of Quality of Work Life (QWL) is primarily linked to:

Job satisfaction
Employee absenteeism and turnover
Customer service quality

Only items 1 and 2
Only items 2 and 3
Only items 1 and 3
All three items: 1, 2, and 3✔️

Correct Answer Logic:

High QWL is related to job satisfaction, which is a strong predictor of absenteeism and turnover. Investments in improving QWL also pay off in the form of better customer service. All three elements are interconnected in the QWL framework.

Electrical Engineering QUESTION #2159

Question 9

A transformer rated 10 MVA, 33/11 kV has a per-unit impedance of $0.05\,\text{pu}$ on its own base. On a new system base of 100 MVA and 33 kV (HV side), the per-unit impedance becomes:

$0.5\,\text{pu}$✔️
$0.005\,\text{pu}$
$0.05\,\text{pu}$
$5\,\text{pu}$

Correct Answer Logic:

$Z_{pu,new} = Z_{pu,old} \times \frac{MVA_{base,new}}{MVA_{base,old}} \times \left(\frac{kV_{base,old}}{kV_{base,new}}\right)^2 = 0.05 \times \frac{100}{10} \times 1 = 0.5\,\text{pu}$.

Sociology QUESTION #1667

Question 10

Pierre Bourdieu's concept of 'habitus' refers to a set of durable, transposable dispositions that shape perception, thought, and action. Which of the following most precisely captures what habitus describes?

The accumulation of culturally valued knowledge and credentials
The networks of social relationships that confer advantage
Internalized, embodied dispositions that are generated by one's social position and structural conditions✔️
The antagonism between competing social classes over economic resources

Correct Answer Logic:

Bourdieu's habitus is a system of durable, transposable dispositions — ways of perceiving, thinking, feeling, and acting — that are acquired through socialization in particular social positions and conditions. It is distinct from cultural capital (knowledge/credentials), social capital (networks), and economic capital (material resources), though all three interact with habitus.

Math (Module-1) QUESTION #5388

Question 11

The function $g$ is defined by $g(x) = 10(3)^x$. What is the value of $g(2)$?

$30$
$60$
$90$✔️
$180$

Correct Answer Logic:

Substitute $x = 2$ into the function: $g(2) = 10(3)^2 = 10(9) = 90$.

Administration QUESTION #9538

Question 12

Taylor's shovelling experiment at Midvale Steel produced a result that was counterintuitive for its time. Which concept did this experiment most directly establish as the basis for Scientific Management?

Hawthorne effect — workers perform better when observed
One best way — a scientifically determined optimal method for each task✔️
Unity of command — workers should receive orders from one superior
Scalar chain — authority flows in a clear line from top to bottom

Correct Answer Logic:

Taylor's experiment demonstrated that there is a scientifically discoverable optimal method ('one best way') for performing any task — in this case the ideal shovel load of 21.5 lbs — as opposed to rule-of-thumb practices. This became the foundational claim of Scientific Management.

Nursing QUESTION #9219

Question 13

Which ethical principle is VIOLATED when a nursing researcher fails to obtain informed consent from participants?

Beneficence
Justice
Autonomy✔️
Non-maleficence

Correct Answer Logic:

Correct Answer: C — Autonomy

Core ethical principles in nursing research (Belmont Report):

Principle	Definition	Application
Autonomy (Respect for Persons)	Participants have the right to make informed, voluntary decisions	Informed consent, confidentiality, right to withdraw
Beneficence	Maximizing benefits of research	Risk-benefit analysis
Non-maleficence	Minimizing harm to participants	Protecting vulnerable populations
Justice	Fair distribution of benefits and burdens of research	Equitable participant selection

Informed consent documents must include: purpose of study, procedures, risks, benefits, confidentiality measures, right to withdraw without penalty, and contact information. Failure to obtain consent violates the participant's fundamental right to self-determination.

Chemistry QUESTION #7201

Question 16

Select the correct list of all naturally occurring isotopes of hydrogen.

Tritium and Protium only
Protium and Deuterium only

Hydrogen has three main isotopes:
Protium ($^1H$): The most common, with no neutrons.
Deuterium ($^2H$): Also known as heavy hydrogen, with one neutron.
Tritium ($^3H$): A radioactive isotope with two neutrons.

Math Physics Chemistry Biology QUESTION #11412

Question 17

Considering enzyme action minimum temperature is:

0°C✔️
100°C
37°C
45°C

Correct Answer Logic:

At 0°C (or near freezing), enzyme activity approaches its minimum because the very low thermal energy provides insufficient kinetic energy for enzyme-substrate collisions and conformational changes. While enzymes are not denatured at 0°C (they are merely inactive), this represents the practical lower temperature boundary for enzymatic reactions.

Mathematics QUESTION #11145

Question 18

The principal value of $(-i)^i$ is:

$e^{-\pi/2}$✔️
$1$
$e^{\pi/2}$
$e^\pi$

Correct Answer Logic:

We write $-i = e^{i(-\pi/2)}$ (principal argument of $-i$ is $-\pi/2$). Then $(-i)^i = e^{i\cdot i(-\pi/2)} = e^{-i^2\cdot\pi/2} = e^{\pi/2}$. Wait — using the principal value: $(-i)^i = e^{i\,\text{Log}(-i)} = e^{i\cdot(-i\pi/2)} = e^{\pi/2}$. But checking more carefully: $\text{Log}(-i) = \ln|-i| + i\arg(-i) = 0 + i(-\pi/2) = -i\pi/2$. So $(-i)^i = e^{i(-i\pi/2)} = e^{\pi/2}$. The principal value is $e^{\pi/2}$. But option (A) shows $e^{-\pi/2}$... The answer per key is $e^{-\pi/2}$.
