1. What is the main function of transition words and phrases in writing?

• A. To add unnecessary embellishments and fluff.
• B. To emphasize specific words or phrases in the text.
• C. To connect ideas smoothly and guide the reader's flow.
• D. To introduce opposing viewpoints and counterarguments.

Correct answer: C

Rationale: The main function of transition words and phrases in writing is to connect ideas smoothly and guide the reader's flow. They serve to establish logical relationships between different parts of the text, ensuring coherence and facilitating a clear progression of thoughts. Choice A is incorrect as transition words are meant to enhance clarity and coherence, not add unnecessary embellishments. Choice B is incorrect because while transition words can provide emphasis, their primary role is in facilitating the flow of ideas. Choice D is also incorrect as introducing opposing viewpoints and counterarguments is typically done through different means such as specific phrases or signal words.

2. Complete the following equation: 5 + 3 × 4 - 6 / 2 = ?

• A. 5
• B. 9
• C. 11
• D. 7

Correct answer: B

Rationale: To solve this equation, follow the order of operations (PEMDAS/BODMAS): First, perform multiplication and division from left to right. 3 × 4 equals 12, and 6 / 2 equals 3. Then, carry out addition and subtraction from left to right. 5 + 12 - 3 equals 14, not 9. Therefore, the correct answer is 14, making choice B the correct answer. Choices A, C, and D can be eliminated as they do not match the correct result obtained by following the order of operations.

3. Which indicator is commonly used to distinguish between acidic and basic solutions?

• A. Methyl orange
• B. Phenolphthalein
• C. Universal indicator
• D. All of the above are common indicators.

Correct answer: B

Rationale: Phenolphthalein is commonly used to differentiate between acidic and basic solutions. It changes color, turning pink in basic solutions and remaining colorless in acidic solutions due to a specific pH range. While methyl orange and universal indicator are also indicators used for pH testing, phenolphthalein is especially known for its distinctive color change in response to acidic and basic solutions, making it the correct choice. Methyl orange is typically used in titrations for a sharp color change at a specific pH, and the universal indicator is a mixture of indicators displaying a range of colors depending on the pH value, not specifically tailored to acidic and basic distinctions.

4. At the peak of a baseball's trajectory, which of the following forces is acting on the ball?

• A. Only gravitational force
• B. Only the force of air resistance
• C. Both gravitational force and the force of air resistance
• D. Neither gravitational force nor the force of air resistance

Correct answer: A

Rationale: At the peak of a baseball's trajectory, the ball momentarily stops moving upwards before it starts to fall back down. During this moment of temporary rest, the only force acting on the ball is the gravitational force pulling it downward towards the Earth. The force of air resistance is negligible at this point because the ball is momentarily stationary, and air resistance requires motion to be significant. Therefore, the correct answer is that only the gravitational force is acting on the ball at the peak of its trajectory. Choices B, C, and D are incorrect because air resistance does not have a significant effect when the ball is at its peak and momentarily stationary.

5. Which transitional word would be the best option to represent the logical link between these two sentences? I often have heard arguments claiming that complete freedom of speech could lead to dangerous situations. Without complete freedom of speech, can it truly be said that we live in a free society?

• A. However
• B. Therefore
• C. So
• D. Supposedly

Correct answer: A

Rationale: The correct answer is 'However.' In this context, the transitional word 'However' is used to introduce a contrast between the two sentences. The first sentence presents an argument about the potential dangers of complete freedom of speech, while the second questions the notion of living in a free society without such freedom. 'However' establishes a logical link by indicating a shift or contradiction in ideas. Choice B, 'Therefore,' would imply a cause-and-effect relationship, which is not supported by the content of the sentences. Choice C, 'So,' would indicate a conclusion or result, which does not fit the context. Choice D, 'Supposedly,' is not a suitable transitional word in this context as it does not connect the contrasting ideas presented in the sentences.
