On what basis did the supreme court rule that the constitution protected students’ right to wear black armbands as a sign of protest?

The correct answer is the following.

The Supreme Court ruled that the United States Constitution student’s right to wear black armbands as a sign of protest by the First Amendment of the United States Constitution.  

We are referring to the case of Mary Beth Tinker v. Des Moines Independent School District in 1969. Tinker was a 13-year-old student who decided to wear a black armband in protest to the Vietnam War. The Court ruled that the school could not punish Tinker for her behavior as long as she did protest in a pacific way and did not mess with other people.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.
