1. Which of the following sentences best represents style and clarity of expression?

• A. Without adequate preparation, the test was likely to be a failure for Zara.
• B. The test was likely to be a failure for Zara without adequate preparation.
• C. Without adequate preparation, Zara expected to fail the test.
• D. Zara expected to fail the test without adequate preparation.

Correct answer: C

Rationale: Choice C, 'Without adequate preparation, Zara expected to fail the test,' is the best option as it maintains clarity and conciseness. The subject 'Zara' is directly linked to the action 'expected to fail the test' with the cause 'Without adequate preparation' clearly stated at the beginning. This structure enhances the flow of the sentence and makes it easier to understand. Choices A, B, and D are less clear as they place the cause and effect in less optimal positions, resulting in a less effective and concise expression of the idea.

2. Select the correct verb to complete the following sentence: Our family _____________ staying home for the holidays this year.

• A. is
• B. be
• C. am
• D. are

Correct answer: A

Rationale: The correct answer is 'A: is.' In the sentence, 'Our family is staying home for the holidays this year,' the singular collective noun 'family' requires a singular verb to maintain subject-verb agreement. 'Is' is the correct singular form of the verb to match with 'family.' Choice B 'be' is incorrect as it is the base form of the verb and does not agree with the subject 'family.' Choice C 'am' is incorrect as it is a first-person singular form of the verb 'to be,' which does not align with the subject 'family.' Choice D 'are' is incorrect as it is a plural form of the verb and does not match with the singular subject 'family.'

3. Which element is used in fertilizers due to its role in plant cell division and growth?

• A. Potassium
• B. Phosphorus
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: Phosphorus is the correct answer. It is used in fertilizers due to its essential role in plant cell division and growth. Phosphorus is a key component of nucleic acids, such as DNA and RNA, which are essential for cell division and growth in plants. Potassium (Choice A) is important for overall plant health and functions like enzyme activation, but it is not specifically known for its role in cell division and growth. Calcium (Choice C) is crucial for cell wall structure and stability but not primarily for cell division. Magnesium (Choice D) is essential for chlorophyll production and photosynthesis, but it is not directly linked to plant cell division and growth.

4. What term describes the bouncing back of waves after striking a surface or boundary?

• A. Diffraction
• B. Refraction
• C. Reflection
• D. Interference

Correct answer: C

Rationale: The correct answer is 'Reflection.' Reflection is the term used to describe the bouncing back of waves after striking a surface or boundary. Diffraction, on the other hand, refers to the bending of waves around obstacles. Refraction is the bending of waves as they pass from one medium to another. Interference involves the combination of two or more waves that results in a new wave pattern. Therefore, in this context, choices A, B, and D are incorrect as they do not specifically relate to the bouncing back of waves after striking a surface or boundary.

5. What element has the atomic number 17?

• A. Chlorine (Cl)
• B. Nitrogen (N)
• C. Sodium (Na)
• D. Fluorine (F)

Correct answer: A

Rationale: The correct answer is Chlorine (Cl). The atomic number of an element corresponds to the number of protons in its nucleus. Chlorine has an atomic number of 17, indicating it has 17 protons. Therefore, the element with atomic number 17 is Chlorine (Cl). Choice B, Nitrogen (N), has an atomic number of 7, Choice C, Sodium (Na), has an atomic number of 11, and Choice D, Fluorine (F), has an atomic number of 9. These elements do not match the atomic number 17, making them incorrect choices.
