Instructions: In each sentence, decide what belongs in place of the double hyphen—the tiny hyphen, mid-sized en-dash, emphasizing em-dash, or no dash at all?

Instructions: Copy and paste the following excerpt into the box below. Then, add em-dashes to improve the flow and create emphasis. Submit your answer to see how your version compares to Justice Kagan's dissent in Free Speech Coalition, Inc. v. Paxton. If you place nine em-dashes exactly as she did, you'll master both levels!

For them, the category of obscene and therefore unprotected speech is narrower. So adults have a constitutional right to view the very same speech that a State may prohibit for children. And it is a fact of life and also of law that adults and children do not live in hermetically sealed boxes. In preventing children from gaining access to "obscene for children" speech, States sometimes take measures impeding adults from viewing it too even though, for adults, it is constitutionally protected expression. What, then, to do? Cases raising that question have reached this Court on no fewer than four prior occasions and we have given the same answer, consistent with general free speech principles, each and every time. . . . If H. B. 1181 is the best Texas can do meaning, the means of achieving the State's objective while restricting adults' speech rights the least then the statute should pass First Amendment review. But what if Texas could do better what if Texas could achieve its interest without so interfering with adults' constitutionally protected rights in viewing the speech H. B. 1181 covers? That is the ultimate question on which the Court and I disagree.
