1. Which of the following would belong in a formal speech?

• A. We all need to work together to make this school better. First, we need to organize a list of our issues. Then we need to form small groups to discuss them and find solutions. Finally, we need to implement those solutions.
• B. Our purpose is to work together to improve the quality of education at this school. Ideally, we need to organize a list of our issues. Secondly, we need to form small groups to discuss them and find solutions. Then, we need to implement some solutions.
• C. We all have to work together to make this school much better than before. First, we need to express what is on our minds. We have to form small groups to discuss them and find solutions. And, we need to talk about those solutions.
• D. It is possible for us to discuss the problems in school and solve them. Certainly, we need to organize a list of our issues. For instance, we should form small groups to discuss them and find solutions. Finally, we need to implement those solutions.

Correct answer: B

Rationale: Option B is the correct answer as it uses formal language, appropriate structure, and organized transitions like 'Ideally,' 'Secondly,' and 'Then,' which are essential for a formal speech. The tone is professional and clear, with well-constructed sentences that effectively convey the necessary information. Options A, C, and D either use informal language, lack the organized flow needed in a formal setting, or have less professional tone. Therefore, Option B stands out as the best fit for a formal speech.

2. What is the sum of two odd numbers, two even numbers, and an odd number and an even number?

• A. Odd + Odd = Even; Even + Even = Even; Odd + Even = Odd
• B. Odd + Odd = Odd; Even + Even = Even; Odd + Even = Even
• C. Odd + Odd = Even; Even + Even = Odd; Odd + Even = Even
• D. Odd + Odd = Odd; Even + Even = Odd; Odd + Even = Even

Correct answer: A

Rationale: The sum of two odd numbers is even because odd numbers have a difference of 1 and adding them results in a multiple of 2. The sum of two even numbers is even because even numbers are multiples of 2. When an odd number and an even number are added, the result is odd because the even number contributes an extra 1 to the sum, making it an odd number. Therefore, the correct answer is A. Choices B, C, and D have incorrect combinations of the sum of odd and even numbers.

3. Convert 345,000 millimeters to centimeters (cm).

• A. 34,500 cm
• B. 3,450 cm
• C. 345,000 cm
• D. 345,000,000 cm

Correct answer: B

Rationale: To convert millimeters to centimeters, you need to divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 345,000 mm ÷ 10 = 34,500 cm. Choice A is incorrect because it is a factor of 10 higher than the correct answer. Choice C is incorrect because it represents the original quantity in centimeters, not the converted value. Choice D is incorrect as it erroneously multiplies the millimeters by 1,000 instead of dividing by 10 to convert to centimeters.

4. What happens to the force of gravity between two objects when the distance between them is doubled?

• A. The force increases by a factor of 2
• B. The force increases by a factor of 4
• C. The force decreases by a factor of 2
• D. The force decreases by a factor of 4

Correct answer: D

Rationale: According to the law of universal gravitation, the force of gravity between two objects is inversely proportional to the square of the distance between them. When the distance is doubled, the force decreases by a factor of 2 squared, which is 4. Therefore, the force decreases by a factor of 4. Choice A is incorrect because the force doesn't increase when the distance is doubled. Choice B is incorrect as the force doesn't increase but actually decreases. Choice C is incorrect as the force decreases by a factor of 4, not 2.

5. When two coherent light waves with a slight phase difference interfere, what determines the resulting intensity of the combined wave?

• A. The individual intensities of the waves
• B. The wavelength of the waves
• C. The distance between the waves
• D. The color of the waves

Correct answer: A

Rationale: The resulting intensity of the combined wave is determined by the individual intensities of the waves. When two coherent light waves interfere, the amplitudes of the waves add up, and the resulting intensity is proportional to the square of the sum of the individual amplitudes. Therefore, the individual intensities of the waves play a crucial role in determining the resulting intensity of the combined wave. Choices B, C, and D are incorrect. The wavelength of the waves and the distance between the waves do affect interference patterns but not the resulting intensity. The color of the waves is determined by the wavelength and does not directly determine the resulting intensity of the combined wave.
