A motor neuron transmits impulses:
Motor (efferent) neurons carry signals from CNS to effectors (muscles/glands). Sensory (afferent) neurons carry signals from receptors to CNS. Interneurons connect within CNS.
Given: All omnivores are herbivores. No herbivores are carnivores. Some carnivores are humans. Which conclusions are TRUE? I. Some humans are carnivores. II. No carnivores are omnivores. III. Some omnivores are carnivores.
Conclusion I is true (Some carnivores are humans implies some humans are carnivores). Conclusion II is true (omnivores are herbivores, and no herbivores are carnivores, so no carnivores are omnivores). Conclusion III is false (it contradicts the given statements). So I and II are true.
The Five-Star Nurse concept (adapted from WHO's Five-Star Doctor model) identifies five key roles for community nurses:
- Care Provider — direct clinical care
- Communicator — therapeutic communication with patients and families
- Community Leader / Decision-Maker — community mobilization
- Teacher/Health Educator — health promotion and education
- Administrator/Manager — managing nursing services and resources
Some frameworks also include Researcher. A Charge/Head Nurse must embody all these roles for comprehensive community health nursing practice.
Identify the statement that is not correct regarding accounting ledgers and accounts:
Statement B is incorrect because a credit balance in the sales ledger (usually due to overpayment or returns) represents a trade payable (liability), not a receivable. Debit balances in the purchases ledger are current assets (Statement C) and Statement D is correct as write-offs are recorded in the control account.
The textbook traces the evolution of the advertising agency model:
- Pre-1880: Advertising agents were simply middlemen who bought space from newspapers and resold it to advertisers at a profit
- ~1880: N. W. Ayer and Son of Philadelphia introduced the “open contract” — they would be the advertiser's sole agent and price ad space at cost plus a fixed commission. This eliminated price competition among agencies
- By 1892: Ayer hired the first full-time copywriter; other agencies followed
- 1893: The American Newspaper Publishers Association agreed not to offer discounts to direct advertisers, forcing all advertisers to use agents
- 1901: Curtis Publishing Company (Ladies' Home Journal) adopted the same practice; magazines followed
- 1919: The cost-plus-commission basis was accepted industry-wide, with the commission standardised at 15 percent — a rate that remained the industry standard for decades
This transformation turned advertising agencies into creative service providers (writing copy, creating logos and slogans, managing artwork) rather than mere space brokers.
