Final answer:
Sentences 1 and 2 provide the best evidence of Kochiyama's activism, highlighting her organization of protests and writing of letters against the internment of Japanese-Americans.
Step-by-step explanation:
The best evidence to support the idea that Kochiyama was an outspoken activist for Japanese-Americans wrongly imprisoned during World War II are sentence 1 and sentence 2. Sentence 1 states that "Kochiyama organized protests and rallies advocating for the rights of Japanese-Americans during their unjust internment," directly indicating her activism and efforts to support the Japanese-American community. Sentence 2 adds that she "penned passionate letters to newspapers, decrying the internment of Japanese-Americans as a grave injustice," further evidencing her role in speaking out against the injustices faced by this group.The reference to 'predict what you believe would be the answer' suggests an exercise in hypothesizing or predicting outcomes based on theoretical knowledge or previous results, which is a key skill in the scientific method and important in experimental chemistry.
