which sentence includes a nonrestrictive clause that is punctuated correctly?\no we ate pistachio ice cream—which is my favorite and played laser tag.\no we ate pistachio ice cream which is my favorite, and played laser tag.\no we ate pistachio ice cream—which is my favorite—and played laser tag.\no we ate pistachio ice cream (which is my favorite and played laser tag).
Answer
Brief Explanations:
A non - restrictive clause provides additional, non - essential information and is set off by commas, dashes, or parentheses. In the correct option, the non - restrictive clause "which is my favorite" is properly set off by dashes on both sides. The first option has incorrect punctuation with only one dash. The second option has no punctuation to set off the non - restrictive clause. The fourth option has incorrect punctuation with parentheses not used correctly for this context.
Answer:
We ate pistachio ice cream—which is my favorite—and played laser tag.
