A teacher divides the class into groups of five and asks them to discuss what they would do if they were caught in one of the following situations :
Their friend falls down in the play field and is hurt…..
They are trapped in a building on fire…….
They are stuck up in a traffic jam…….
This activity is based on ________

The correct answer is Communicative Language Teaching (CLT) Approach.

Explanation:
The activity described in the question involves dividing students into groups to discuss real-life, problem-solving scenarios (e.g., helping an injured friend, dealing with a fire, or navigating a traffic jam). This requires students to communicate meaningfully with each other, express their opinions, and use language flexibly to solve problems in social contexts.

Key features of the Communicative Language Teaching (CLT) Approach include:
1. Focus on Meaningful Interaction: Emphasizes communication through real-life scenarios and social situations rather than rote memorization.
2. Group/Pair Work: Encourages active engagement, collaboration, and discussion among learners.
3. Fluency and Contextual Use: Prioritizes functional language usage over strict grammatical drill exercises.

Therefore, this group discussion activity is based on the Communicative Language Teaching (CLT) Approach.
