Final answer:
Without knowledge of the specific text or context, it's impossible to accurately detail the news in the phone call or Anoosh's response. The excerpt suggests a tragic and urgent situation but lacks enough information for a precise answer.
Step-by-step explanation:
The question appears to be referencing a specific narrative event where a phone call delivers news. Unfortunately, without the context of which book or text this question is referring to, it is impossible to provide an accurate explanation of the news or Anoosh's response. The provided excerpt implies a situation of urgency and tragedy, with imagery suggesting that news is spreading rapidly and has a devastating impact, as indicated by the 'white rectangle of light and grief'. Since the text fragment mentions a 'father' and 'a boy expiring in his arms,' it may be related to a dire medical situation or accident. The mention of 'Anoosh' suggests a character's reaction to the situation, but without further information, we cannot accurately describe Anoosh's response.
