Therefore.

Explanation:

Transition words are the words that are used to show relationships between the ideas in a sentence. They are also known as linking words, used to connect sentences to make the ideas flow in a smooth manner rather than abruptly jumping from one point to another.

In the given passage, Lea can revise her sentences by adding the transition words "as a result" and "therefore". These two words express a concluding statement, allowing Lea to express her concerns smoothly. So, the words will change the last sentence as-

1. As a result, students should wear uniforms to create an equal environment.

2. Therefore, students should wear uniforms to create an equal environment.

These two transition words allow the smooth transition of the ideas she wants to express.
