<h2>d) by creating another paragraph with evidence of unconstitutionality.</h2>
The first sentence begins the paragraph well, establishing the theme that will be explored in the essay.
The sentences are not overlong, and "big words" aren't really used. Perhaps a word like "interned" might be considered a "big word" because it is not frequently used in everyday vocabulary. However, that term is a key term for the action taken against the Japanese Americans, and so needs to be used in this context.
Evidence that suspicion and prejudice were involved can be seen in the statement, "Military commanders were concerned because most Japanese Americans lived on the West Coast, where many military installations were also located." That indicates that the commanders were acting on suspicion and prejudice that Japanese Americans would seek to sabotage or attack American military installations on behalf of the Japanese.
What is not included in the opening paragraph is evidence from the US Constitution that the actions against Japanese Americans were unconstitutional. Providing such evidence might mean pointing to the 5th Amendment (part of the Bill of Rights), which says "No person shall be ... nor be deprived of life, liberty, or property, without due process of law."
The telegram was an internal diplomatic message sent in January 1917 from the German foreign secretary Arthur Zimmermann in Berlin, to the German Embassy in Mexico. It proposed a military alliance between Germany and Mexico, in the event of the United States entering the First World War in support of the Allies.
