Which process is defined as acquiring a language without formal instruction and sustained conscious effort?

• A. Acquisition
• B. Interference
• C. Register
• D. Subjective test

Answer: (A)

Acquisition is the process described. It means picking up language naturally through exposure and meaningful communication, without formal instruction or deliberate, conscious effort to memorize rules. This is the subconscious side of language learning, contrasted with learning, which involves explicit study of grammar and rules.

Interference involves one language influencing another, not how language is acquired. Register refers to language style variation based on context and social setting. A subjective test is a type of assessment, not a process of language development.
