1. Which sentence uses the gerund (-ing) form correctly?

• A. My favorite activity is playing tennis.
• B. He enjoys to travel to new places.
• C. Reading a good book is relaxing.
• D. Writing is her passion.

Correct answer: A

2. Which organ is responsible for filtering blood and removing waste products?

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are responsible for filtering blood and removing waste products from the body through the production of urine. The liver plays a role in detoxifying the blood and producing bile, while the spleen is involved in filtering blood and removing old or damaged red blood cells. The pancreas is primarily responsible for producing digestive enzymes and regulating blood sugar levels. Therefore, the kidneys are the specific organ dedicated to the filtration of blood and removal of waste products, making them the correct choice in this question.

3. How is power related to work and time?

• A. Power = Work ÷ Time
• B. Power = Work × Time
• C. Power = Work + Time
• D. Power = Work - Time

Correct answer: a

Rationale: Power is calculated as the amount of work done or energy transferred per unit of time.

4. Which statement accurately describes the periodic trends in atomic radius?

• A. Increases down a group and decreases across a period
• B. Decreases down a group and increases across a period
• C. Remains constant throughout the table
• D. Fluctuates unpredictably based on individual elements

Correct answer: A

Rationale: Moving down a group, additional electron shells increase the distance from the nucleus, leading to larger atomic radii. Moving across a period, the number of electron shells remains constant, but the increasing nuclear charge pulls electrons closer, resulting in smaller radii.

5. Which of the following is the primary function of the ovaries in the female reproductive system?

• A. Transport sperm to the uterus
• B. Produce milk for feeding offspring
• C. Produce eggs (ova)
• D. Regulate urination

Correct answer: C

Rationale: The primary function of the ovaries in the female reproductive system is to produce eggs (ova). Ovaries are responsible for the production and release of eggs during the menstrual cycle, which can be fertilized by sperm to form a zygote. This process is essential for reproduction and the continuation of the species. Options A, B, and D are incorrect as transporting sperm to the uterus is the role of the fallopian tubes, producing milk for feeding offspring is the function of the mammary glands, and regulating urination is controlled by the bladder and associated muscles, not the ovaries.

6. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: b

Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.
