1. The important decision will be made tomorrow. Which word is the comparative form of the adjective "important"?
- A. important
- B. importantly
- C. more important
- D. most important
Correct answer: C
Rationale: The comparative form of an adjective compares two things.
2. Which hormone, produced by the thyroid gland, plays a crucial role in regulating the body's metabolism, growth, and development?
- A. Calcitonin
- B. Parathyroid hormone (PTH)
- C. Thyroxine
- D. Insulin
Correct answer: c
Rationale: The correct answer is C: Thyroxine. Thyroxine, also known as T4, is a hormone produced by the thyroid gland that plays a crucial role in regulating the body's metabolism, growth, and development. It controls how the body uses energy, affects heart rate, and influences other vital functions. Calcitonin (A) is involved in calcium regulation, not metabolism. Parathyroid hormone (PTH) (B) is produced by the parathyroid glands and regulates calcium and phosphorus levels in the body. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not metabolism or growth.
3. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?
- A. Speed = Frequency × Wavelength
- B. Speed = Frequency ÷ Wavelength
- C. Speed = Frequency + Wavelength
- D. Speed = Frequency - Wavelength
Correct answer: a
Rationale: In a given medium, the speed of a wave equals the product of its frequency and wavelength.
4. The kidneys are bean-shaped organs that perform several vital functions. Which of the following is NOT a primary function of the kidneys?
- A. Filtering waste products from the blood
- B. Regulating blood pressure
- C. Producing red blood cells
- D. Maintaining water balance in the body
Correct answer: C
Rationale: The correct answer is C. While the kidneys perform multiple vital functions, such as filtering waste products from the blood, regulating blood pressure, and maintaining water balance in the body, they do not produce red blood cells. Red blood cell production occurs in the bone marrow, specifically in the spongy tissue called the red bone marrow. Therefore, the kidneys' primary functions do not include producing red blood cells.
5. The order of operations (PEMDAS) dictates the sequence for evaluating mathematical expressions. If a = 2 and b = -3, what is the value of 3a^2 - 2ab + b^2?
- A. -3
- B. 0
- C. 33
- D. 15
Correct answer: C
Rationale: Following PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right), we start with exponents: 3(2^2) - 2ab + b^2. Then, multiply: 3(4) - 2ab + b^2. Next, perform the multiplication/division from left to right: 12 - 2ab + b^2. Finally, add/subtract from left to right: 12 + (-2)(2)(-3) + (-3)^2. Evaluate the remaining terms: 12 + 12 + 9. The answer is 33.
6. What is the main argument presented in favor of UBI?
- A. It would boost the economy by increasing consumer spending and stimulating businesses.
- B. It would guarantee financial stability and improve mental health for all citizens.
- C. It would address ethical concerns about income inequality and promote social justice.
- D. It would decrease crime rates and improve public safety by reducing poverty and desperation.
Correct answer: C
Rationale: The passage emphasizes UBI's potential to alleviate poverty and reduce inequality, aligning with C.
