The correct answer is: D. Eulogy : Admiration
An elegy is a poem or song that expresses sorrow or regret for the dead. A requiem is a musical composition or service for the dead. A tirade is a long, angry speech. A eulogy is a speech or writing in praise of a person who has died.
In each of the pairs, the first word is a type of expression, and the second word is the emotion that the expression is meant to convey. In the case of “elegy” and “sorrow,” the elegy is an expression of sorrow, and in the case of “eulogy” and “admiration,” the eulogy is an expression of admiration.
The other options do not have the same relationship. “Encomium” is a speech or writing in praise of someone, but it does not necessarily express admiration. “Requiem” is a musical composition or service for the dead, but it does not necessarily express sorrow. “Tirade” is a long, angry speech, but it does not necessarily express joy.
