Question

read the source of the allusion.
in the bible, solomon, a king of israel, is an extremely wise person whom many regard as a prophet.
what is the meaning of the allusion in the sentence below?
you should pay a visit to great-aunt gertrude, the solomon of our family.
a person who is very kind
a person who gives good advice
a person who is generous

Explanation:

The source says Solomon is extremely wise. An allusion to Solomon in "the Solomon of our family" implies Great - Aunt Gertrude has Solomon's wisdom - related trait. Giving good advice is a trait of a wise person. Kindness and generosity aren't directly related to Solomon's wisdom as described. So the allusion means a person who gives good advice.

Answer:

a person who gives good advice
