Question

mid-term exam
which of the following is an allusion?
when i won the science fair i was the talk of the town.
professor anderson is such a scrooge.
i passed my chemistry exam with flying colors.

Explanation:

An allusion is a reference to a well-known person, work, or event. Scrooge is a famous miserly character from Charles Dickens' A Christmas Carol, so this sentence references a widely recognized figure. The other options are common idioms, not allusions.

Answer:

Professor Anderson is such a Scrooge.
