Rationale: The word "serendipity" refers to a fortunate coincidence or chance, describing how Beto Pérez invented Zumba accidentally.

2. What is the meaning of the word overturn in the last paragraph of the passage?

Correct answer: B

Rationale: The word "overturn" means to invalidate or negate existing guidelines. In this context, the passage questions whether the findings of the study are substantial enough to change established medical recommendations regarding caffeine intake during pregnancy, making option B the appropriate choice.

3. Which of the following statements is an opinion related to MRSA?

Correct answer: C

Rationale: The correct answer is C because it is an opinion rather than a verifiable fact. The statement suggests a recommendation for hospitals to adopt new germ-fighting textiles swiftly, which is a subjective viewpoint and not objectively measurable. Choices A and B are factual statements regarding combating MRSA infection and antibiotic resistance, respectively. Choice D provides a comparison of MRSA infection with HIV/AIDS, which is a factual statement based on statistical data. Therefore, C is the only choice that presents an opinion rather than a fact.

4. What is the main idea of the passage about Super Foods?

Correct answer: A

Rationale: The main idea emphasizes that superfoods are low in calories yet rich in essential nutrients that provide significant health benefits. This statement captures the overall essence of the passage, while the other options focus too narrowly or introduce unsupported claims, making A the correct answer.

5. Which sound waves have a higher pitch?

Correct answer: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.
