Administration QUESTION #9539

Question 9562

Henri Fayol identified 14 principles of management. A district officer issues orders to a field inspector who simultaneously receives contradictory orders from a divisional director. Which single Fayol principle has been most directly violated, and what is its practical consequence?

Division of work — resulting in role confusion and overlapping responsibilities
Unity of command — resulting in conflict, confusion and erosion of accountability✔️
Scalar chain — resulting in bypassing the line of authority
Esprit de corps — resulting in breakdown of team cohesion

Correct Answer Logic:

Unity of command (Fayol's Principle 4) holds that each employee should receive orders from one superior only. When violated, accountability becomes diffuse, conflict is inevitable, and the employee cannot determine whose instructions take priority — directly undermining organizational discipline.

Disaster Management QUESTION #6556

Question 9563

What represents the most significant limitation of relying solely on structural measures for flood risk reduction?

High costs
Failure to address upstream catchment degradation, urban planning issues, and climate change, potentially creating false security✔️
Engineering complexity
Maintenance requirements

Correct Answer Logic:

Section 8 emphasizes combining structural measures with Eco-DRR, risk-sensitive planning, and climate adaptation. Structural measures alone don't address root causes (land use changes, ecosystem degradation, climate impacts) and can create moral hazard by encouraging development in protected but still at-risk areas.

Reading and Writing (Module-1) QUESTION #5353

Question 9565

Text 1: Graphic novels are gaining popularity, but they shouldn't be deemed literature. Literature, by definition, uses only language to tell stories, whereas graphic novels rely on images and use text minimally. Text 2: Graphic novels use both text and imagery to tell a story. Without the dialogue, the images wouldn't be fully understood; the meaning comes from the blend of both. Furthermore, the writing in many graphic novels is as high-quality as standard prose. Based on the texts, how would the author of Text 2 most likely respond to the overall argument presented in Text 1?

By asserting that language plays a more important role in graphic novels than the author of Text 1 recognizes✔️
By acknowledging that the author of Text 1 has identified a flaw that is common to all graphic novels
By suggesting that the story lines of certain graphic novels are more difficult to understand than the author of Text 1 claims
By agreeing with the author of Text 1 that most graphic novels aren't as well crafted as most literary works are

Correct Answer Logic:

Text 2 argues that language is essential and often high-quality in graphic novels, directly countering Text 1's claim that they use language only sparingly.

Statistics QUESTION #2011

Question 9567

Fisher's Ideal price index is preferred over Laspeyres' and Paasche's indices because it:

Uses only base period data
Is always equal to 100 in the base year
Satisfies both the time reversal test and the factor reversal test✔️
Is easiest to compute

Correct Answer Logic:

Fisher's Ideal index $= \sqrt{L \times P}$ (geometric mean of Laspeyres' and Paasche's) satisfies the time reversal test ($I_{01} \times I_{10} = 1$) and the factor reversal test ($P_{01} \times Q_{01} = V_{01}$), making it the most theoretically sound index. Neither Laspeyres' nor Paasche's alone satisfies both tests.

Accounting & Finance QUESTION #6068

Question 9572

Budgeted data for 6,000 units:

Variable manufacturing: $90,000
Variable selling: $6,000
Fixed manufacturing: $54,000
Fixed admin: $21,000

Selling price is $40 unit. How many units must be sold to reach a target profit of $45,000?

3,960
4,125
4,800
5,000✔️

Correct Answer Logic:

1. Variable Cost per unit = ($90,000 + $6,000) / 6,000 = $16.
2. Contribution per unit = $40 - $16 = $24.
3. Total Fixed Costs = $54,000 + $21,000 = $75,000.
4. Required Units = (Fixed Costs + Target Profit) / Contribution = ($75,000 + $45,000) / $24 = 5,000 units.
