1. A guitar string vibrates at a fundamental frequency of 440 Hz. What is the frequency of the second harmonic (first overtone)?

• A. 220 Hz
• B. 440 Hz
• C. 880 Hz
• D. 1760 Hz

Correct answer: C

Rationale: Harmonics have frequencies that are multiples of the fundamental frequency. The second harmonic has a frequency twice the fundamental, so it's 440 Hz * 2 = 880 Hz.

2. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.

• A. table
• B. leg
• C. ouch
• D. stubbed

Correct answer: C

Rationale: Interjections express emotions or sudden feelings. "Ouch" conveys a feeling of pain.

3. Identify the preposition in the following sentence: The cat jumped over the fence.

• A. cat
• B. jumped
• C. over
• D. the

Correct answer: C

Rationale: Prepositions show the relationship between a noun or pronoun and another word in the sentence. "Over" indicates the position of the cat in relation to the fence.

4. One leadership theory states that “leaders are born and not made,” which refers to which of the

• A. Trait
• B. Charismatic
• C. Great Man
• D. Situational

Correct answer: A

Rationale: The correct answer is A: Trait. The statement 'leaders are born and not made' aligns with the Trait theory of leadership, which suggests that certain individuals are born with innate qualities and characteristics that make them effective leaders. This theory focuses on identifying specific traits, such as intelligence, charisma, and self-confidence, that are believed to be inherent in successful leaders. Charismatic leadership (option B) emphasizes the charm and appeal of a leader, Great Man theory (option C) suggests that leaders are born with unique qualities that set them apart, and Situational leadership (option D) focuses on adapting leadership style based on the situation. However, the statement in the question best corresponds to the Trait theory, making option A the correct choice.

5. The largest bone in the human body is the:

• A. Femur (thigh bone)
• B. Tibia (shin bone)
• C. Humerus (upper arm bone)
• D. Scapula (shoulder blade)

Correct answer: A

Rationale: The correct answer is A: Femur (thigh bone). The femur is the longest and strongest bone in the human body, located in the thigh region. It plays a crucial role in supporting the body's weight and facilitating movement. The tibia (B) is commonly known as the shin bone and is located below the femur. The humerus (C) is the upper arm bone, and the scapula (D) is the shoulder blade. However, neither of these bones is the largest in the human body. Understanding the anatomy of the skeletal system is essential for identifying the largest bone in the body, which is the femur.

6. The layer of the skin responsible for new skin cell production is the:

• A. Stratum corneum
• B. Stratum basale
• C. Stratum granulosum
• D. Stratum spinosum

Correct answer: B

Rationale: The correct answer is B: Stratum basale. The stratum basale, also known as the basal layer or stratum germinativum, is the deepest layer of the epidermis responsible for new skin cell production through cell division. This layer contains stem cells that continuously divide and differentiate into keratinocytes, which eventually migrate to the outer layers of the epidermis. The stratum corneum (option A) is the outermost layer of the epidermis composed of dead skin cells. The stratum granulosum (option C) is the layer above the stratum basale where keratinocytes undergo changes in their structure. The stratum spinosum (option D) is a layer above the stratum basale where cells become interconnected by desmosomes. Therefore, the stratum basale is the primary layer responsible for the production of new skin cells.
