'Artificial Intelligence has revolutionized multiple sectors, from healthcare to finance. Machine learning algorithms now detect diseases more accurately than human radiologists. However, the rapid deployment of AI systems raises concerns about job displacement and ethical implications. Regulatory frameworks are still catching up with technological advancement.'
Which of the following best describes the author's tone?
The passage presents both positive aspects (revolutionized sectors, superior disease detection) and negative concerns (job displacement, ethical issues), reflecting a balanced perspective rather than purely optimistic, skeptical, or indifferent approach.
Benign (harmless, good) and malevolent (evil, harmful) are true opposites. Options A and B are contextually opposite but not semantic opposites. Option D contains synonyms.
'Each' is singular, requiring 'brings' not 'bring.' Option A: 'data' can take plural verb. Options C and D are grammatically correct.
A) Quantum computing harnesses quantum mechanics principles to process information exponentially faster than classical computers.
B) Companies like Google and IBM have made significant breakthroughs in quantum hardware development.
C) While quantum computers promise revolutionary capabilities, they currently face challenges in stability and error correction.
D) The potential applications span cryptography, drug discovery, and climate modeling.
Start with definition (A), list applications (D), acknowledge limitations (C), then mention industry progress (B) provides balanced perspective.
The passage directly states acceleration is 'faster than previously projected.' Other options overstate claims or are unsupported by the text.
Astute means sharp and intelligent judgment. Superficial and cursory imply shallow analysis, contradicting 'proved instrumental.' Ambiguous is irrelevant.
'It' is singular, requiring 'has' not 'have'. The sentence structure is correct otherwise.
A) Blockchain technology emerged from cryptocurrency applications but has evolved far beyond digital currencies.
B) Today, industries from supply chain management to healthcare explore blockchain implementation.
C) Initially dismissed as mere speculation, blockchain now demonstrates tangible real-world applications.
D) This distributed ledger system offers transparency and security unmatched by conventional databases.
Logical progression: Introduce misconception (C), explain what blockchain truly is (A), describe its technical advantage (D), then mention applications (B).
'Majority' is plural, so 'agree' is correct. 'Change' is singular, so 'poses' is needed. Both errors exist in the sentence.
Eradicate means to eliminate completely, which fits the context of combating corruption. Obfuscate means to obscure, and perpetuate means to continue.
