Question

read the source of the allusion. during the middle ages, knights searched far and wide for years to find the holy grail. they believed the holy grail was the cup that jesus used at his last meal with his followers. what is the meaning of the allusion in the sentence below? dr. casey said that finding a cure for this deadly disease is her holy grail. options: something that becomes greater in value over time; something wanted very much but hard to get

Explanation:

The Holy Grail was something knights searched for intensely in the Middle Ages, representing a highly desired yet hard - to - obtain goal. In the sentence, Dr. Casey's search for a cure for a deadly disease is compared to the search for the Holy Grail. The option "something wanted very much but hard to get" matches this meaning. The other option about increasing in value over time doesn't fit the context of the allusion here.

Answer:

something wanted very much but hard to get
