Which of the following is not mentioned as a cause of human tears in paragraph 6?
So far, so fine. But of course crying is not only associated with the human
need for attachment. Tears can also be moral, signifying our sympathy
with an injustice. Moreover, as the cultural historian Thomas Dixon points
out, tears are sometimes associated with joy and ecstasy rather than grief
and sorrow ─ hence the mass emotional displays during the London
Olympics. Sometimes, as when we weep while chopping an onion, tears
may signify nothing at all; at other times they may be an expression of
profound grief or sadness.
