Core, semi-periphery, and periphery nations differentiated by their position in the global division of labor✔️
Developed, underdeveloped, and developing nations classified by per capita income
Capitalist, feudal, and socialist economic systems competing for global dominance

Correct Answer Logic:

Wallerstein's World-Systems Theory (introduced in 'The Modern World-System,' 1974) divides the capitalist world-economy into three structural zones: the Core (wealthy, diversified, high-wage economies that exploit the periphery), the Periphery (poor, raw-material exporting economies), and the Semi-periphery (intermediate economies that exploit the periphery while being exploited by the core).

Chemistry QUESTION #5530

Question 2785

For $2A + B \to \text{products}$: doubling both [A] and [B] increases rate from $0.3$ to $2.4\ \text{mol L}^{-1}\text{s}^{-1}$; doubling [A] alone increases rate from $0.3$ to $0.6\ \text{mol L}^{-1}\text{s}^{-1}$. Which statement is correct?

Total order of the reaction is 4
Order w.r.t. B is 2✔️
Order w.r.t. B is 1
Order w.r.t. A is 2

Correct Answer Logic:

When only [A] doubles: rate doubles → order w.r.t. A = 1. When both [A] and [B] double: rate increases 8-fold ($2.4/0.3 = 8$). Effect of doubling both: $2^1 \times 2^n = 8 \Rightarrow 2^{1+n} = 8 = 2^3 \Rightarrow 1+n = 3 \Rightarrow n = 2$. Order w.r.t. B = 2. Total order = 1 + 2 = 3.

Nursing QUESTION #9158

Question 2788

In nursing education, Bloom's Taxonomy of educational objectives classifies learning into three domains. The psychomotor domain primarily deals with:

Recall of factual information
Emotional responses and values
Physical skills and motor activities✔️
Problem-solving and analysis

Correct Answer Logic:

Bloom's Taxonomy classifies educational objectives into three domains:

Cognitive domain: Knowledge, comprehension, application, analysis, synthesis, evaluation
Affective domain: Attitudes, values, emotional responses
Psychomotor domain: Physical and motor skills — e.g., performing injections, wound dressing, CPR

In nursing education, the psychomotor domain is critical for clinical skill development. A Head Nurse supervising nursing students or staff must assess all three domains for comprehensive competency evaluation.

Accounting & Finance QUESTION #6155

Question 2789

Sales revenue $500,000; Total costs $400,000; Fixed costs $120,000. What was the total contribution?

$100,000
$220,000✔️
$280,000
$380,000

Correct Answer Logic:

Option B ($220,000) is correct.

Variable costs = $400,000 − $120,000 = $280,000

Contribution = $500,000 − $280,000 = $220,000

(Note: Profit = $220,000 − $120,000 = $100,000 — that is Option A, not the same as contribution.)

Mathematics QUESTION #11169

Question 2792

Which of the following are open in the usual metric space $(\mathbb{R},d)$?

Subsets of $\mathbb{R}$
Union of open intervals✔️
Intervals
Singleton subsets

Correct Answer Logic:

In the usual metric on $\mathbb{R}$, the open sets are precisely the unions of open intervals. A union of open intervals is always open. Arbitrary subsets may not be open; closed intervals like $[a,b]$ are not open; singletons $\{x\}$ are closed (not open) in $\mathbb{R}$ with usual metric.

Question 2793

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.

Law QUESTION #9496

Question 2800

In execution proceedings, the judgment-debtor B claims that the decree has been satisfied by an agreement between himself and the original decree-holder, who has since died. B seeks to raise this in the execution proceedings. The legal representative of the deceased decree-holder insists a separate suit is required. Which forum is correct?

The High Court must certify the satisfaction
The question must be decided by the Court that passed the original decree
B can raise the plea of discharge or satisfaction of the decree in the execution proceedings themselves; all questions relating to execution, discharge or satisfaction of the decree are to be determined by the executing Court under Section 47 CPC✔️
B must file a separate suit to prove discharge of the decree

Correct Answer Logic:

Section 47(1) CPC provides that all questions arising between the parties to a suit in which the decree was passed, or their representatives, relating to the execution, discharge or satisfaction of the decree, shall be determined by the Court executing the decree and not by a separate suit.
