Krashen's set of five hypotheses is commonly referred to as which model?

• A. Monitor Model
• B. Natural Order Hypothesis
• C. Acquisition-Learning Hypothesis
• D. Interlanguage

Answer: (A)

This item tests what Krashen’s framework of five hypotheses is commonly named. That set is commonly called the Monitor Model. The name comes from the idea that learners have a conscious “monitor” that can supervise and edit language output using learned rules, while fluent ability primarily comes from the subconscious process of language acquisition.

The five hypotheses within this framework include the Acquisition-Learning Hypothesis, the Monitor Hypothesis, the Natural Order Hypothesis, the Input Hypothesis, and the Affective Filter Hypothesis. Other terms like Natural Order or Acquisition-Learning refer to individual parts of the model or to related concepts, and Interlanguage describes the evolving learner language system rather than the overall label for the five hypotheses.
