Kisa Gotami became weary and hopeless because she could not find a single house where no one had died. The Buddha had asked her to bring mustard-seed from a house untouched by death. At every door, people told her, "The living are few, but the dead are many." There was no house but some beloved one had died in it. Failing at every door made her realise that death is universal and unavoidable, leaving her exhausted and without hope of finding a remedy for her grief.

The examiner wants three things here: (1) what Kisa Gotami was searching for (mustard-seed from a death-free house), (2) why she could not get it (every house had suffered a death), and (3) the resulting emotion (weariness and hopelessness). Quoting the phrase "the living are few, but the dead are many" directly from the text earns credit. Do not drift into the Buddha's sermon — stay focused on her personal journey in this part of the story.
