a. true
b. false

The correct answer is A: True. An allusion is a figure of speech that makes a reference to someone or something that is known from history, literature, religion, politics, sports, science or some other branch of culture. Because allusions make reference to something other than what is directly being discussed, you may miss an allusion or fail to understand it if you do not know the underlying biblical story, literary tale or other reference point. The biblical allusions are maybe the most frequently used ones. For example: You can say to someone that he is Solomon, in order to tell him that he is very wise person.
