1. Which of the following best explains the purpose of the parentheses in the sentence?

• A. to indicate the page numbers in the book where this information might be found
• B. to tell the reader when the Austro-Hungarian Empire collapsed
• C. to identify information that was located using another source
• D. to set off useful information that does not fit directly into the flow of the sentence

Correct answer: D

Rationale: The purpose of the parentheses in the sentence is to set off useful information that does not fit directly into the flow of the sentence. Parentheses are commonly used to provide additional details, explanations, or examples that are helpful but not essential to the main point of the sentence. In this case, the information about the Austro-Hungarian Empire is presented in parentheses to offer context but is not crucial to the main idea being communicated. Choices A, B, and C are incorrect as they do not accurately describe the function of parentheses in this context.

2. During which phase of the cell cycle does DNA replication occur?

• A. Interphase
• B. Mitosis
• C. Meiosis
• D. Cytokinesis

Correct answer: A

Rationale: Interphase is the phase of the cell cycle where the cell spends the majority of its time and is characterized by three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). DNA replication specifically occurs during the S phase of interphase. This is a crucial step as it ensures that each daughter cell produced during cell division receives an exact copy of the genetic material. Mitosis is responsible for the equal distribution of the replicated DNA to the daughter cells during cell division. Meiosis is a specialized cell division process for gamete production in sexually reproducing organisms, involving two rounds of division to generate haploid cells. Cytokinesis is the final step of the cell cycle, where the cytoplasm divides to complete the formation of two separate daughter cells following nuclear division.

3. Which of the following is a correct thesis statement?

• A. President Perez pledged to improve living conditions for all during her well-attended inauguration speech, which drew thunderous applause.
• B. President Perez graduated first in her class at Harvard University after defending a capstone project on inequality.
• C. President Perez is our greatest leader because her proposal of a universal income will eradicate inequity among citizens.
• D. President Perez was interviewed on television in February, where she spoke without commercial interruption for 1 hour.

Correct answer: C

Rationale: Choice C is the correct thesis statement because it presents a clear argument or claim, making it a strong thesis statement. The thesis statement asserts President Perez as the greatest leader based on her proposal of a universal income to eradicate inequity among citizens. This statement sets a specific focus and direction for the essay or discussion that follows. Choices A, B, and D do not function as thesis statements. Choice A provides a descriptive event but lacks a clear argument. Choice B highlights an achievement but does not establish a central claim. Choice D mentions an interview but does not present a focused argument as required in a thesis statement.

4. Which of the following is best identified as a hypothesis?

• A. The environmental temperature can affect the growth of a plant's root.
• B. Plants need light to grow.
• C. A colder environment produces longer roots.
• D. Plants need 60 days to grow their roots.

Correct answer: A

Rationale: Choice A is the best example of a hypothesis as it presents a testable statement regarding the impact of environmental temperature on plant root growth. A hypothesis should be specific and capable of being tested through experimentation, which is demonstrated in choice A. Choice B is a general statement rather than a testable hypothesis. Choice C lacks specificity and does not clearly state a cause-and-effect relationship to be tested. Choice D provides a specific time frame but does not address a relationship that can be tested through experimentation, making it less suitable as a hypothesis compared to choice A.

5. When the weights of the newborn babies are graphed, the distribution of weights is symmetric with the majority of weights centered around a single peak. Which of the following describes the shape of this distribution?

• A. Uniform
• B. Bimodal
• C. Bell-shaped
• D. Skewed right

Correct answer: C

Rationale: The correct answer is C: Bell-shaped. A symmetric distribution with a single peak is characteristic of a bell-shaped distribution, also known as a normal distribution. This distribution forms a symmetrical, bell-like curve when graphed. Choice A, 'Uniform,' would describe a distribution where all values have equal probability. Choice B, 'Bimodal,' would indicate a distribution with two distinct peaks. Choice D, 'Skewed right,' suggests a distribution where the tail on the right side is longer or more pronounced, unlike the symmetrical bell-shaped distribution described in the question.
