1. Her former manager demonstrated passion for serving her staff rather than being served. She

A. Transformational leader
B. Transactional leader
C. Servant leader
D. Charismatic leader

Correct answer: C

Rationale: The correct answer is C: 'Servant leader.' A servant leader prioritizes the needs of their team members, focusing on serving them rather than expecting to be served. This is evident in the scenario where the former manager showed passion for serving her staff. Servant leaders are known for their humility, empathy, and commitment to the growth and well-being of their team. This leadership approach fosters a positive work environment, builds trust, and promotes collaboration among team members.

2. In a neutral atom, the number of electrons:

A. Must be equal to the number of protons.
B. Must be less than the number of protons.
C. Must be greater than the number of neutrons.
D. Can vary depending on the atom's temperature.

Correct answer: A

Rationale: Must be equal to the number of protons - For electrical neutrality, the positive charge of protons must be balanced by the negative charge of an equal number of electrons.

3. What literary device is used in the phrase "a heart of gold"?

A. Metaphor
B. Simile
C. Hyperbole
D. Personification

Correct answer: A

Rationale: The phrase directly compares someone's good nature to gold, making it a metaphor.

4. What happens to the frequency of a wave when its wavelength is doubled, assuming the speed remains constant?

A. Frequency remains the same.
B. Frequency is halved.
C. Frequency is doubled.
D. Frequency information is insufficient to determine.

Correct answer: C

Rationale: Since the wave speed is constant, if the wavelength increases, the frequency must decrease to maintain the same energy transfer per unit time.

5. What is the relationship between mass and weight on Earth's surface?

A. Mass and weight are equal
B. Mass is greater than weight
C. Weight is greater than mass
D. Mass and weight are not related

Correct answer: a

Rationale: On Earth's surface, mass and weight are directly proportional but not equal, as weight is the force due to gravity acting on an object's mass.

6. What is the building block of RNA?

A. Amino acid
B. Nucleotide
C. Protein
D. Fatty acid

Correct answer: B

Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.
