A constraint that is characteristic of ESP learners is

• A. Age
• B. Motivation
• C. Time
• D. Place

Answer: (C)

Time is the defining constraint for ESP learners because their language needs are tied to real, time-bound tasks in specific professional contexts. In ESP, the goal is to be able to perform particular functions—like reading a technical document quickly, understanding a fast-paced meeting, or writing a concise report—within limited time. That focus pushes learning toward efficiency, relevance, and quick application: core vocabulary and structures that help learners get the job done fast, strategies for skimming and extracting essential information, and practice under realistic time pressures. Age, place, or general motivation aren’t the defining limits of ESP; they can vary, but the common challenge that shapes how ESP is learned and taught is time.
