1. What does the term "colligative property" refer to in solutions?

• A. Properties that depend on the nature of the solute particles
• B. Properties that depend on the concentration of solute particles
• C. Properties that depend on the temperature of the solution
• D. Properties that depend on the pressure of the solution

Correct answer: b

Rationale: Colligative properties are dependent on the number of solute particles in a solution, not their nature. The other choices do not accurately define colligative properties.

2. A child's toy block is a cube with side lengths of 5cm. What is its total surface area?

• A. 25 sq cm
• B. 50 sq cm
• C. 125 sq
• D. 150 sq cm

Correct answer: D

Rationale: Use the formula for surface area of a cube: 6 * (side length)^2 = 6 * (5cm)^2 = 125 sq cm.

3. Positive integers are greater than zero. Which of the following expressions results in the largest positive number?

• A. (2 + 3)^2
• B. 5 x 7 + 2
• C. 10^2 - 4^2
• D. (8 - 1) x 3

Correct answer: C

Rationale: 10^2 - 4^2 = 100 - 16 = 84

4. When a blockage forms in a coronary artery, reducing blood flow to the heart muscle, this condition is called:

• A. Atherosclerosis
• B. Myocardial infarction
• C. Angina pectoris
• D. Heart murmur

Correct answer: C

Rationale: The correct answer is C: "Angina pectoris." Angina pectoris is the condition that occurs when there is a blockage in a coronary artery, leading to reduced blood flow to the heart muscle. This decreased blood flow can cause chest pain or discomfort, typically during physical exertion or stress. Atherosclerosis (option A) is the buildup of plaque in the artery walls, which can lead to blockages. Myocardial infarction (option B) refers to a heart attack, which occurs when there is a complete blockage in a coronary artery resulting in damage to the heart muscle. A heart murmur (option D) is an abnormal sound heard during the heartbeat, not directly related to a blockage in a coronary artery. Therefore, the correct term for a blockage in a coronary artery that reduces blood flow to the heart muscle is angina pectoris.

5. You need to paint a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m. Considering only the interior walls and floor (not the top), how much paint do you need (assume one can of paint covers 10 sq m)?

• A. 56 sq m
• B. 72 sq m
• C. 88 sq m
• D. 104 sq m

Correct answer: C

Rationale: Calculate the areas of each wall and the floor, sum them up, and subtract the area of the water surface (top). Divide the final area by the coverage area per can to determine the number of cans needed.

6. Which of the following joints allows for side-to-side bending movements?

• A. Hinge joint
• B. Ball-and-socket joint
• C. Gliding joint
• D. Saddle joint

Correct answer: C

Rationale: The correct answer is C: Gliding joint. Gliding joints are found where the bones meet and allow for limited side-to-side and back-and-forth movements. These joints have flat or slightly curved surfaces that glide against each other, enabling smooth motion in multiple directions. Hinge joints (A) allow for movement in one plane like a door hinge, ball-and-socket joints (B) allow for a wide range of motion in multiple directions, and saddle joints (D) allow for back-and-forth and side-to-side movements but are primarily designed for flexion and extension like the joint at the base of the thumb.
