1. Based on the preceding words, what is the correct meaning of the suffix -fy in glorify, fortify, gentrify, acidify?

• A. Marked by, given to
• B. Doer, believer
• C. Make, cause, cause to have
• D. Process, state, rank

Correct answer: C

Rationale: The suffix '-fy' means to make or cause to have. Each word listed—glorify, fortify, gentrify, acidify—indicates a process of transforming or altering something, making the common meaning related to causing or making. Choice A ('Marked by, given to') is incorrect as it does not reflect the action of making or causing. Choice B ('Doer, believer') is unrelated to the suffix -fy and does not capture its meaning. Choice D ('Process, state, rank') is also incorrect as it does not align with the consistent theme of causing or making evident in the words provided.

2. Which organ stores and concentrates bile?

• A. Liver
• B. Gallbladder
• C. Pancreas
• D. Stomach

Correct answer: B

Rationale: The correct answer is B: Gallbladder. The gallbladder is the organ that stores and concentrates bile produced by the liver. Bile is essential for the digestion of fats in the small intestine. The liver produces bile, which is then stored and concentrated in the gallbladder until it is released into the small intestine when needed. Choices A, C, and D are incorrect because the liver produces bile, the pancreas produces digestive enzymes, and the stomach is primarily involved in the digestion of food through acid secretion and mechanical processes, not in storing bile.

3. What is the range in the number of flights the flight attendant made?

• A. 20
• B. 25
• C. 29
• D. 32

Correct answer: B

Rationale: The range is calculated as the difference between the largest and smallest values in a dataset. In this case, the largest number of flights made by the flight attendant in a month was 79, and the smallest number was 54. Therefore, the range is 79 - 54 = 25. Choices A, C, and D are incorrect as they do not reflect the correct calculation of the range based on the given data.

4. What is the formula to calculate kinetic energy?

• A. Kinetic Energy = Mass × Velocity
• B. Kinetic Energy = Force × Distance
• C. Kinetic Energy = Power × Time
• D. Kinetic Energy = Potential Energy ÷ Time

Correct answer: A

Rationale: Kinetic energy is the energy an object possesses due to its motion. The formula to calculate kinetic energy is KE = 0.5 × mass × velocity^2, which can also be written as KE = mass × (velocity)^2. Therefore, the correct formula is Kinetic Energy = Mass × Velocity. Choice B is incorrect because it represents the work formula. Choice C is incorrect as it represents the formula for work done. Choice D is incorrect as it does not accurately represent the formula for calculating kinetic energy.

5. Which human body system is correctly matched with its function?

• A. Respiratory system; exchanges oxygen and carbon dioxide in the lungs.
• B. Circulatory system; transports oxygen to cells and removes carbon dioxide.
• C. Lymphatic system; produces antibodies that destroy virally affected or foreign cells.
• D. Endocrine system; regulates hormones controlling bodily functions and metabolism.

Correct answer: B

Rationale: The circulatory system is responsible for the transportation of oxygen from the lungs to all the body's cells and tissues, as well as removing carbon dioxide from the cells and transporting it back to the lungs to be exhaled. This process is crucial for cellular respiration and the exchange of gases necessary for bodily functions. Choice B accurately matches the role of the circulatory system by describing its function of transporting oxygen to cells and removing carbon dioxide, which is essential for maintaining proper cellular activities. Choices A, C, and D are incorrect because they do not accurately match the body system with its function. The respiratory system primarily involves the exchange of gases in the lungs, not transportation to cells; the lymphatic system deals with immunity through the production of antibodies, not gas exchange; and the endocrine system's main function is hormone regulation, not the transport of gases.
