Question

read each sentence carefully, then choose the punctuation mark that best completes it.
the women in question ▼ many had been acting for more than 20 years ▼ deserve awards.
several countries participated in shakespeare festivals ▼ italy, canada, france, and mexico.
only one play had available seating ▼ shakespeares the tragedy of macbeth.

Explanation:

1. For "The women in question __ many had been acting for more than 20 years __ deserve awards": The first blank sets off a non-restrictive clause that adds extra info about the women, so em dashes (—) work best here to separate the clause. The second blank closes this clause.
2. For "Several countries participated in Shakespeare festivals ____ Italy, Canada, France, and Mexico": The blank introduces a list of the countries, so a colon (:) is correct to signal the upcoming list.
3. For "Only one play had available seating ____ Shakespeare's The Tragedy of Macbeth": The blank connects the statement to the specific example of the play, so an em dash (—) or colon works; an em dash smoothly links the general statement to the specific name.

1. The women in question — many had been acting for more than 20 years — deserve awards
