1. Which of the following relationships represents no correlation between two variables?
- A. As a student’s class attendance decreases, the student’s overall grade remains the same
- B. As the number of hours a person exercises decreases, the weight of that person increases
- C. As the number of miles driven increases, the amount of gasoline in the tank decreases
- D. As the amount of water a plant receives increases, the growth rate of the plant increases
Correct answer: A
Rationale: Choice A represents no correlation between two variables as it states that as a student’s class attendance decreases, the student’s overall grade remains the same. This scenario shows no relationship between class attendance and grade. In contrast, choices B, C, and D show clear correlations between the variables mentioned. Choice B indicates a negative correlation between exercise hours and weight gain, choice C indicates a negative correlation between miles driven and gasoline in the tank, and choice D indicates a positive correlation between water intake and plant growth rate, making them all examples of correlated relationships.
2. What is the official name of the metric system?
- A. International Measurement System
- B. International System of Units
- C. Metric Unit System
- D. Measurement System of Units
Correct answer: B
Rationale: The official name of the metric system is the International System of Units (SI). The International System of Units is a globally recognized standard for measurement. Choice A, 'International Measurement System,' is incorrect as it does not accurately reflect the official name. Choice C, 'Metric Unit System,' while related to the metric system, is not the precise official name. Choice D, 'Measurement System of Units,' is a mix-up of terms and does not represent the correct official name of the metric system.
3. How are kidney stones formed?
- A. Due to excess water not being reabsorbed
- B. When minerals crystallize in the urine
- C. When electrolytes become too concentrated
- D. All of the above
Correct answer: B
Rationale: Kidney stones are formed when minerals in the urine crystallize and stick together to form solid masses. Excess water not being reabsorbed (option A) does not directly contribute to kidney stone formation. Similarly, electrolytes becoming too concentrated (option C) is not a direct cause of kidney stone formation. The correct answer is B because the crystallization of minerals in the urine leads to the formation of kidney stones.
4. Which of the following is a correctly punctuated simple sentence?
- A. Leah and Jerry spent the last few hours in the garden smelling the roses and tulips.
- B. Leah stopped to smell the roses in the garden, but her allergies made her eyes water.
- C. Because it was now spring, Leah could stop to smell the roses.
- D. As Leah jogged in the park, she noticed the smell of roses.
Correct answer: A
Rationale: The sentence in option A is a correctly punctuated simple sentence with a compound predicate ('spent... smelling'). It consists of a subject 'Leah and Jerry' and a compound predicate 'spent... smelling,' making it a complete sentence. Option B contains a comma splice, joining two independent clauses incorrectly with just a comma. Option C is a complex sentence with a dependent clause ('Because it was now spring') and an independent clause, not a simple sentence. Option D is a complex sentence with a dependent clause ('As Leah jogged in the park') and an independent clause, not a simple sentence. Therefore, option A is the only choice that represents a correctly punctuated simple sentence.
5. Which of the following is the main organ responsible for absorbing nutrients?
- A. Stomach
- B. Small intestine
- C. Large intestine
- D. Pancreas
Correct answer: B
Rationale: The small intestine is the main organ responsible for absorbing nutrients from the food we eat. It is where the majority of digestion and absorption of nutrients such as carbohydrates, proteins, fats, vitamins, and minerals occurs. The inner lining of the small intestine is covered in tiny finger-like projections called villi, which increase the surface area available for nutrient absorption. While the stomach plays a role in breaking down food into smaller particles, the actual absorption of nutrients primarily takes place in the small intestine. The large intestine mainly absorbs water and electrolytes, and the pancreas produces digestive enzymes and hormones but is not primarily responsible for absorbing nutrients.
