1. Choose the sentence with the correct pronoun usage.

• A. “This mystery concerns my friend Watson and me.”
• B. “This mystery concerns me and my friend Watson.”
• C. “This mystery concerns my friend Watson and I.”
• D. “This mystery concerns I and my friend Watson.”

Correct answer: A

Rationale: The correct pronoun usage is 'me' when it is the object of a verb or preposition. In this sentence, 'me' is the object of the verb 'concerns,' so it should be used instead of 'I.' Additionally, the correct order for objects in a sentence is 'my friend Watson and me.' Choice B is incorrect because 'me' should come before 'my friend Watson' to maintain the correct order. Choice C is incorrect as 'I' is incorrectly used instead of 'me.' Choice D is incorrect because 'I' is used incorrectly as the object pronoun, and the order is reversed.

2. Which of the following statements would make the best conclusion to an essay about civil rights activist Rosa Parks?

• A. Rosa Parks refused to give up her bus seat, leading to her arrest.
• B. Rosa Parks was a hero to many, symbolizing the power of ordinary people in bringing about change.
• C. Rosa Parks died in 2005 at the age of 92.
• D. Rosa Parks' actions sparked the Montgomery Bus Boycott, a pivotal event in the Civil Rights Movement.

Correct answer: B

Rationale: The best conclusion to an essay about civil rights activist Rosa Parks should reflect her significance and impact. Choice A, while true, focuses on a specific event rather than summarizing her broader influence. Choice C, though factual, is not a strong conclusion as it does not capture the essence of her legacy. Choice D, although related to her actions, is not as encompassing as Choice B. Option B is the most suitable conclusion as it highlights Rosa Parks' heroism, emphasizing how she inspired change and symbolized the power of ordinary individuals in making a difference.

3. Which of the following root words would be used in a word related to the body?

• A. corp
• B. auto
• C. man
• D. bio

Correct answer: A

Rationale: The root word 'corp' is related to the body as it comes from the Latin word 'corpus,' meaning body. Words like 'corporal' and 'corporation' are derived from this root, linking them to the body in some manner. Choices B, C, and D are incorrect. 'Auto' relates to self or automatic, 'man' pertains to human or hand, and 'bio' is associated with life or living organisms, none of which directly signify the body.

4. After exposure to a pathogen, the immune system develops memory. What type of immune cell is responsible for this immunological memory?

• A. B cells
• B. T cells (specifically memory T cells)
• C. Phagocytes
• D. Natural killer cells

Correct answer: A

Rationale: B cells are responsible for immunological memory. Memory B cells, a type of B cells, retain a 'memory' of specific pathogens, enabling them to rapidly produce antibodies upon re-exposure. This rapid antibody production facilitates a quicker and more effective immune response. Although memory T cells also contribute to immunological memory by mounting a swift and robust immune response upon re-exposure to the pathogen, it is primarily memory B cells that play a crucial role in producing antibodies. Phagocytes are important immune cells involved in engulfing and digesting pathogens, while natural killer cells are primarily responsible for recognizing and eliminating abnormal cells, such as virus-infected cells or tumor cells. However, when it comes to immunological memory and antibody production, B cells are key players.

5. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?

• A. Speed = Frequency × Wavelength
• B. Speed = Frequency ÷ Wavelength
• C. Speed = Frequency + Wavelength
• D. Speed = Frequency - Wavelength

Correct answer: A

Rationale: The speed of a wave in a given medium is determined by the product of its frequency and wavelength. This relationship is described by the formula: Speed = Frequency × Wavelength. When a wave travels through a medium, the speed at which it propagates is directly proportional to both its frequency and wavelength. Therefore, to calculate the speed of the wave, you multiply the frequency of the wave by its wavelength. Choices B, C, and D are incorrect because speed is not determined by division, addition, or subtraction of frequency and wavelength; instead, it is determined by their multiplication in the given medium.
