Which word means being very selective and demanding of high standards?

• A. Casual
• B. Fastidious
• C. Flexible
• D. Easygoing

Answer: (B)

The idea here is choosing a word that describes someone who is very selective and demands high standards. Fastidious fits this perfectly: it describes a person who is meticulous about details and particular about quality, often hard to please because they hold very high standards and expect things to be done precisely right. This contrasts with casual, flexible, or easygoing, which describe a more relaxed or adaptable attitude rather than a demanding one. For instance, a fastidious editor will notice tiny errors and insist on perfect accuracy, showing why this term is the best match for being highly selective and demanding.
