1. Select the pronoun that could be used in the following sentence: Mrs. Sato, _______ lives down the street, is 99 years old.

• A. she
• B. who
• C. which
• D. whom

Correct answer: B

Rationale: The correct answer is 'B' - 'who.' 'Who' is the correct relative pronoun to introduce the clause 'who lives down the street,' providing more information about Mrs. Sato. The other choices, 'she,' 'which,' and 'whom,' are not appropriate relative pronouns for referring to a person in this context.

2. During a scientific investigation, what is intentionally changed or manipulated?

• A. The dependent variable.
• B. The control.
• C. The hypothesis.
• D. The independent variable.

Correct answer: D

Rationale: During a scientific investigation, the independent variable is intentionally changed or manipulated by the researcher to observe its impact or effect on the dependent variable. The independent variable is the one being tested or studied to see how it influences the dependent variable. In contrast, the dependent variable is the outcome or response that is measured in an experiment and is expected to change as a result of the manipulation of the independent variable. Choices A, B, and C are not directly altered during a scientific investigation but play different roles in the research process. Therefore, the correct answer is D - the independent variable.

3. Which of the following statements most effectively revises this introduction about Mary Shelley: Mary Shelley conceived of Dr. Frankenstein and the hideous monster he created, which helped the English novelist to make an immeasurable impact on literature and popular culture?

• A. English novelist Mary Shelley had an immeasurable impact on literature and popular culture when she conceived of Dr. Frankenstein and the hideous monster he created.
• B. Dr. Frankenstein created a hideous monster, and they were conceived by English novelist Mary Shelley, who had an immeasurable impact on literature and popular culture.
• C. English novelist Mary Shelley conceived of Dr. Frankenstein and the hideous monster he created and had an immeasurable impact on literature and popular culture.
• D. Novelist Mary Shelley from England had an immeasurable impact on literature and popular culture when she conceived of Dr. Frankenstein and the hideous monster he created.

Correct answer: A

Rationale: Option A most effectively revises the introduction by clearly stating that English novelist Mary Shelley had an immeasurable impact on literature and popular culture through her conception of Dr. Frankenstein and the hideous monster he created. It maintains the original idea while improving clarity and coherence. Option B introduces confusion by implying that Dr. Frankenstein created the hideous monster when it was actually Mary Shelley who conceived both characters. Option C lacks the necessary conjunctions to make the sentence flow smoothly. Option D unnecessarily specifies the country of origin for Mary Shelley and does not maintain the focus on her impact on literature and popular culture.

4. Which element has the same number of protons and neutrons?

• A. Carbon (C)
• B. Oxygen (O)
• C. Lithium (Li)
• D. Helium (He)

Correct answer: D

Rationale: The correct answer is Helium (He). Helium has an atomic number of 2, meaning it has 2 protons. It also has 2 neutrons, which gives it a total mass number of 4. Therefore, Helium is an example of an element with an equal number of protons and neutrons. Choice A (Carbon) has 6 protons and usually has more neutrons than protons. Choice B (Oxygen) has 8 protons and 8 neutrons, so the numbers are not equal. Choice C (Lithium) has 3 protons and usually has more neutrons than protons, so it does not fit the criteria of having the same number of protons and neutrons.

5. Which structure connects the two hemispheres of the brain, allowing communication and coordination between them?

• A. Corpus callosum
• B. Thalamus
• C. Hypothalamus
• D. Medulla oblongata

Correct answer: A

Rationale: The correct answer is the corpus callosum. It is a thick band of nerve fibers that connects the two hemispheres of the brain, facilitating communication and coordination between them. The thalamus acts as a relay station for sensory information, the hypothalamus regulates basic functions like hunger and thirst, and the medulla oblongata controls vital functions such as breathing and heart rate. Therefore, choices B, C, and D are incorrect as they do not specifically connect the two hemispheres of the brain as the corpus callosum does.
