1. What is the common name for the compound CH₃COOH?

• A. Acetic acid
• B. Formic acid
• C. Butyric acid
• D. Propionic acid

Correct answer: A

Rationale: CH₃COOH is commonly known as acetic acid. The other choices represent different organic acids.

2. Which word completes the sentence "He was ____ by the unexpected turn of events."

• A. elated (joyful)
• B. bewildered (confused)
• C. vindicated (justified)
• D. apathetic (uninterested)

Correct answer: B

Rationale: "Bewildered" best describes the confusion caused by the unexpected events.

3. How does an unbalanced force affect an object at rest?

• A. It maintains the object's state of rest
• B. It does not affect the object's rest
• C. It moves the object into motion
• D. It decreases the object's mass

Correct answer: c

Rationale: An unbalanced force acting on an object at rest causes it to start moving.

4. The study of fungi is known as:

• A. Virology
• B. Mycology
• C. Bacteriology
• D. Parasitology

Correct answer: B

Rationale: Rationale: A) Virology is the study of viruses, not fungi. B) Mycology is the branch of biology that deals with the study of fungi. Fungi are a separate kingdom of organisms that include yeasts, molds, and mushrooms. C) Bacteriology is the study of bacteria, not fungi. D) Parasitology is the study of parasites, which can include various organisms such as protozoa, helminths, and some fungi, but it is not specifically focused on fungi.

5. 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

6. The speed of light in a vacuum is measured in units of:

• A. Meters per second
• B. Hertz
• C. Candela
• D. Newton

Correct answer: A

Rationale: The correct answer is A: 'Meters per second.' The speed of light in a vacuum is a fundamental constant of nature and is approximately 299,792,458 meters per second. This speed is constant and does not vary based on the frequency or wavelength of light. Hertz (B) is a unit of frequency, Candela (C) is a unit of luminous intensity, and Newton (D) is a unit of force. Understanding the units used to measure the speed of light is important in physics and related fields to accurately describe the propagation of light in different mediums.
