Sociologist: Some anthropologists claim that cultures can most effectively respond to the threat of cultural decay by replacing or abandoning many of their traditions so that other traditions may endure.
Given
(According to some anthropologists) cultures can most effectively respond to the threat of cultural decay by replacing or abandoning many of their traditions so that other traditions may endure.
But each of its traditions is essential to a culture's identity.
Evaluate
If each of a culture's traditions is essential to a culture's identity, what will happen if a culture replaces or abandons many of their traditions? It seems like this will damage the culture's identity.
"Cultural decay" seems like it would be a loss of cultural identity. So, the evidence that we're given seems to indicate that the anthropologists are wrong: replacing or abandoning many traditions so that others may endure is not an effective way to respond to a threat of cultural decay.
Goal
A correct answer might indicate that this strategy of replacing or abandoning many traditions is not an effective response to the threat of cultural decay, or more generally the strategy is likely to harm a culture.
