- A. I have been working on this project since morning.
- B. She has finished the book already.
- C. They will be leaving for vacation tomorrow.
- D. He had been living in the city for ten years.

2. Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?
- A. Protein synthesis
- B. Waste storage and disposal
- C. Photosynthesis
- D. Cellular respiration
Correct answer: B
Rationale: Vacuoles in plant cells are primarily used for storage of water, nutrients, and waste products. In animal cells, vacuoles are smaller and serve various functions, including waste storage and disposal. Option B, 'Waste storage and disposal,' is the correct answer because vacuoles in animal cells help maintain cellular homeostasis by storing and breaking down waste materials. This process aids in detoxification and maintaining proper cellular function in animal cells, similar to the role of vacuoles in plant cells.
3. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?
- A. Her eyes glistened in the moonlight, with tears.
- B. Tears glistened in her eyes with moonlight.
- C. Her eyes, in the moonlight, glistened with tears.
- D. Tears made her eyes glisten in the moonlight.
Correct answer: C

4. The bones of the skull are classified as what type of bone?
- A. Long bone
- B. Short bone
- C. Flat bone
- D. Irregular bone
Correct answer: C
Rationale: The correct answer is C: Flat bone. The bones of the skull are classified as flat bones due to their thin, flattened shape. Flat bones provide protection to vital organs and have a broad surface for muscle attachment. Long bones, like the femur, are characterized by their elongated shape, while short bones, such as those in the wrist and ankle, are cube-shaped. Irregular bones have complex shapes and do not fit into the other bone categories. In this case, the flat bones of the skull best fit the classification.
5. Which type of muscle tissue has a unique branching network and is found in the heart?
- A. Skeletal muscle
- B. Cardiac muscle
- C. Smooth muscle
- D. Multifidus muscle
Correct answer: B
Rationale: The correct answer is B - Cardiac muscle. Cardiac muscle is the type of muscle tissue that has a unique branching network and is specifically found in the heart. Unlike skeletal muscle, which is attached to bones and allows for voluntary movement, cardiac muscle is involuntary and contracts to pump blood throughout the body. Smooth muscle is found in organs like the intestines and blood vessels, while the multifidus muscle is a specific muscle in the back. Therefore, cardiac muscle is the appropriate choice in this scenario.
6. Percent (%) is a way to express a fraction with a denominator of 100. 125% can be expressed as a fraction in lowest terms. Which of the following represents 125% as a fraction?
- A. 5/4
- B. 1/8
- C. 5/2
- D. 25/2
Correct answer: A
Rationale: Percent literally means "out of one hundred." So, 125% is equivalent to 125/100. We can simplify this fraction by dividing the numerator and denominator by 25, resulting in 5/2.
