This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Understand theories of second language acquisition
Prompt focus: According to Stephen Krashen's input hypothesis, language acquisition occurs most effectively when learners receive input that is:
Why the correct answer works
Slightly beyond their current level of competence
Correct. Comprehensible input is language slightly beyond the learner's current level.
Why the tempting wrong answer fails
Input far above the learner's level is not comprehensible and does not promote acquisition.
Plain-language takeaway
Krashen's input hypothesis describes comprehensible input as language that is slightly beyond a learner's current level, often written as i plus one. This challenges learners without overwhelming them.
Simple analogy
Think of understand theories of second language acquisition like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
