1. What is the primary function of hematopoietic tissue?

• A. Building and repairing bone
• B. Supporting and connecting tissues
• C. Production of blood cells
• D. Contracting for movement

Correct answer: C

Rationale: The primary function of hematopoietic tissue is the production of blood cells. Hematopoietic tissue, primarily found in the bone marrow, is responsible for generating red blood cells, white blood cells, and platelets. These blood cells are vital for oxygen transport, immune response, and blood clotting. Choices A, B, and D are incorrect as they do not reflect the main function of hematopoietic tissue. Building and repairing bone is primarily carried out by osteoblasts and osteoclasts, supporting and connecting tissues is a role of connective tissues like tendons and ligaments, and contracting for movement is a function of muscle tissue.

2. Which of the following is a concise summary of the passage?

• A. Babies focus on their caregivers' faces due to their lack of depth perception until 12 months.
• B. Babies recognize their mothers' voices at birth, relying primarily on hearing initially.
• C. Babies have adult-like senses except for vision, which fully develops by 12 months.
• D. Babies' senses undergo significant changes in their first year of life.

Correct answer: D

Rationale: Option D is the most concise summary of the passage as it encapsulates the main idea that the passage focuses on the changes in babies' senses during their first year of life. The passage explains how babies are born with sensory abilities similar to adults but highlights the significant changes that occur during the first year, particularly in vision development. While the other options touch on specific aspects mentioned in the passage, they do not capture the overall essence of the passage, which emphasizes the dynamic and transformative nature of babies' sensory experiences in their first year.

3. What type of particle carries no charge and mediates the strong nuclear force between protons and neutrons?

• A. Electron
• B. Photon
• C. Gluon
• D. Neutrino

Correct answer: C

Rationale: The correct answer is C: Gluon. Gluons are the particles responsible for mediating the strong nuclear force between protons and neutrons. They are the carriers of this force. Choice A, Electron, is incorrect as electrons are negatively charged. Choice B, Photon, is incorrect as photons are chargeless particles of light. Choice D, Neutrino, is incorrect as neutrinos are neutral particles with minimal mass and weak interactions with matter, not involved in mediating the strong nuclear force between protons and neutrons.

4. Which of the answer choices is an effective revision of the ambiguous sentence below? Tanya told her sister to tell her boyfriend Joe to call her as soon as he got home.

• A. Tanya's sister said, 'Tell Joe to call me as soon as he gets home.'
• B. Her sister told her boyfriend Joe to call Tanya as soon as he got home.
• C. Tanya said to her sister, 'Tell your boyfriend Joe to call me as soon as he gets home.'
• D. Tanya told her sister, 'Joe should call me as soon as he gets home.'

Correct answer: C

Rationale: The correct answer, option C, effectively clarifies the communication structure by specifying who is communicating with whom and when. Tanya instructs her sister to convey a message to her boyfriend Joe, requesting him to call Tanya upon his arrival home. This revision removes the ambiguity present in the original sentence. Option A is incorrect as it introduces unnecessary complexity and alters the original meaning. Option B is incorrect as it misinterprets the relationships among the individuals involved. Option D is incorrect as it changes the dynamics of the communication and does not address the ambiguity in the original sentence.

5. Select the correct definition of the underlined word having multiple meanings in the sentence: 'Natalie’s fingers were calloused after practicing her bass.'

• A. Kind of fish
• B. Low and deep sound
• C. Lowest male singing voice
• D. A guitar with four strings that makes low sounds

Correct answer: D

Rationale: In this sentence, 'bass' refers to a guitar with four strings that makes low sounds. The context of Natalie practicing suggests that it is referring to a musical instrument, specifically the bass guitar, rather than a fish, sound, or voice. Therefore, the correct answer is D. Choice A, 'Kind of fish,' is incorrect as the sentence context does not relate to fish. Choice B, 'Low and deep sound,' is incorrect because the sentence refers to practicing an instrument, not just a sound. Choice C, 'Lowest male singing voice,' is also incorrect as the sentence context is not related to singing but to playing an instrument.
