1. A set of temperature readings has a range of 5 degrees Celsius. What does this tell you about the data?

• A. The average temperature is 5 degrees Celsius.
• B. All temperatures are within 5 degrees of each other.
• C. The difference between the highest and lowest temperatures is 5 degrees.
• D. There are exactly 5 temperatures in the set.

Correct answer: C

Rationale: Rationale: - Option A is incorrect because the range of 5 degrees does not necessarily mean that the average temperature is 5 degrees Celsius. The average temperature could be any value within the range. - Option B is incorrect because the range of 5 degrees does not mean that all temperatures are within 5 degrees of each other. It only indicates the difference between the highest and lowest temperatures. - Option C is correct because the range of 5 degrees specifically refers to the difference between the highest and lowest temperatures in the set. This is a common definition of range in statistics. - Option D is incorrect because the range of 5 degrees does not determine the number of temperatures in the set. The set could have more or fewer than 5 temperatures.

2. What is the functional group present in amines?

• A. Hydroxyl
• B. Carbonyl
• C. Amine
• D. Nitro

Correct answer: C

Rationale: Amines have the functional group -NHâ‚‚. The other choices are associated with different functional groups.

3. Which of the following is an example of a weak acid?

• A. Hydrochloric acid (HCl)
• B. Sulfuric acid (H2SO4)
• C. Acetic acid (CH3COOH)
• D. Nitric acid (HNO3)

Correct answer: C

Rationale: Weak acids only partially dissociate in water, releasing a lower concentration of hydrogen ions.

4. Which of the following numbers is a perfect square?

• A. 10
• B. 12
• C. 15
• D. 16

Correct answer: D

Rationale: A perfect square is a number obtained by squaring an integer. 16 is the result of squaring 4 (4 x 4 = 16). The other answer choices are not the product of squaring any whole number.

5. Which additional information would be MOST helpful in further understanding the issue of microplastics?

• A. The economic costs associated with plastic pollution cleanup.
• B. The specific types of microbes used in bioremediation processes.
• C. The historical timeline of plastic production and its global distribution.
• D. The aesthetic impact of plastic pollution on beaches and tourism.

Correct answer: B

Rationale: Understanding the specific microbes used in bioremediation would directly contribute to knowledge about the solution proposed in the passage.

6. The dome-shaped muscular structure that separates the chest cavity from the abdominal cavity is the:

• A. Diaphragm
• B. Sternum
• C. Pericardium
• D. Trachea

Correct answer: A

Rationale: The correct answer is A: Diaphragm. The diaphragm is a dome-shaped muscular structure that plays a crucial role in respiration by contracting and flattening during inhalation to increase the volume of the thoracic cavity, allowing the lungs to expand and fill with air. It separates the chest cavity (thoracic cavity) from the abdominal cavity. The sternum (B) is a flat bone in the center of the chest, the pericardium (C) is a double-layered sac that surrounds the heart, and the trachea (D) is the windpipe that connects the larynx to the bronchi. Therefore, the diaphragm is the correct answer in this case.
