Sentence improvement — prefer the precise noun 'space': 'There is no more space for you in this compartment.'

Given sentence
There is no more room for you in this compartment.

Concept/Approach
In transport contexts (train/coach compartment), 'space' is idiomatic for available capacity. 'Room' is acceptable in general, but 'space' is crisper and collocates better with seats/standing areas.

Option analysis
• there is no more space → natural collocation.• 'no more seat' → number mismatch (should be 'seats'); also too specific.• 'accommodation' → formal and odd here.• 'No improvement' → less idiomatic.

Final Answer
there is no more space
