Answer:
Freedom of speech
Step-by-step explanation:
The 1st Amendment states:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances."
If the government were to decide that school administrators could monitor students' comments on social media sites, the Court would most likely have to consider whether this approach is constitutional based on the protection of freedom of speech contained in this amendment. Freedom of speech ensures that the students can say what they think on social media, without fear of punishment.
