Error spotting (time clauses & aspect): Identify the erroneous segment (A/B/C) — mark D if there is no error — 'At the moment the house / was burgled the family / attended a night party in the neighbourhood. / No error.' Ensure proper linker and progressive aspect for concurrent past action.

Given data

• The sentence describes a point-in-time event (burglary) and a concurrent background activity (family at a party).

Concept/Approach: Subordinator & aspect
'At the moment' normally takes a subordinator when followed by a clause: 'at the moment when…' Also, to show an ongoing background action, use past continuous: 'were attending'.

Step-by-step correction
1) Add subordinator: 'At the moment when the house was burgled…'2) Use progressive for concurrent activity: '…the family were attending a night party…'Correct: 'At the moment when the house was burgled, the family were attending a night party in the neighbourhood.'

Common pitfalls
Dropping 'when' after 'the moment'; using simple past for an action in progress at a specific time in the past.

Final Answer
A — Insert 'when' and prefer past continuous for the ongoing action.
