Computer is relevant in modern society because of its

Correct Answer: B

Rationale: Computers' relevance in modern society stems from their ability to perform diverse tasks across industries. 'Versatility,' is correct because it highlights this adaptability—handling everything from medical diagnostics to communication—as noted in tech sociology (e.g., Castells' Network Society). 'Price,' varies and isn't the core reason for relevance; affordability enables use, not impact. 'Speed,' is a feature, but alone doesn't explain broad utility. 'Program,' is a component, not the overarching reason. Versatility allows computers to serve education, healthcare, and more, adapting to user needs via software, making B the standout answer, reflecting their transformative role in daily life and infrastructure.

Correct Answer: B

Rationale: Emergence is the phase after general anesthesia where a patient regains consciousness and reflexes. 'Emergence,' is correct, as defined in anesthesiology (e.g., Miller's Anesthesia), marking the transition from unconsciousness to awareness. 'Reduction,' is unrelated to anesthesia phases. 'Maintenance,' is the sustained anesthesia state during surgery. 'Induction,' is the initial unconsciousness onset. Emergence's specific role—restoring normal function post-procedure—distinguishes it, making B the precise answer, reflecting clinical terminology.

Correct Answer: B

Rationale: A good literature review synthesizes existing knowledge to frame a study. 'Abstract,' is correct as not a component; it's a separate summary, not part of the review itself, per research writing guides (e.g., APA Manual). 'Relevance of the study,' justifies the topic's importance within the review. 'Theoretical framework(s),' provides conceptual grounding. 'Review of previous studies,' is the core, analyzing prior work. The abstract stands apart as an overview, not an integrated review element, making B the accurate exception.

Correct Answer: C

Rationale: Systematic sampling requires a sampling interval (e.g., every 5th unit) to select from a list. 'Systematic,' is correct, per sampling theory (e.g., Lohr), ensuring regular selection. 'Simple,' uses pure randomness, no interval. 'Stratified,' divides by groups, not intervals. 'Cluster,' samples groups, not individuals systematically. The interval's role in systematic sampling's methodical approach makes C the precise answer.

Correct Answer: C

Rationale: Foot movements include dorsiflexion (toes up) and inversion (sole inward), unique to its anatomy. 'Dorsiflexion and inversion,' is correct, per kinesiology (e.g., Neumann). 'Elevation and depression,' applies to shoulders. 'Abduction and adduction,' is general. 'Opposition and reposition,' is thumb-specific. Foot-specific terms make C the accurate answer.
