Collocation/usage – count & container nouns with festivals: pick the word that naturally completes the sentence. Base sentence: "During Diwali the shops are _____ of people." Options: busy / full / crowded / bubbling Final instruction: Choose the most idiomatic completion.

Given data

• Festive-season crowds in shops.

Concept/Approach
The normal pattern is full of people. While shops can be crowded with people, the preposition after crowded changes, so only full fits exactly with of.

Option analysis
full — collocates with of; "full of people" is standard. ✅crowded — requires with (crowded with people), not of. ❌busy — takes no preposition here (shops are busy), so it does not complete the given frame. ❌bubbling — typically with excitement; not natural with of people. ❌

Final Answer
full
