Final answer:
We cannot determine the language Sydelle used without more information.
Step-by-step explanation:
In the given question, we are asked in what language Sydelle wrote her shorthand notes. The options given are English, Spanish, French, and German.
In order to determine the answer, we need to gather more information about Sydelle and the context of the situation. As this information is not provided in the question, we cannot accurately determine the language in which Sydelle wrote her shorthand notes.
Therefore, we cannot confidently say which language Sydelle used.
