1. Katherine tells one of the staff, â€œI donâ€™t have time to discuss the matter with you now. See me

A. Smoothing
B. Compromise
C. Avoidance
D. Restriction

Correct answer: B

Rationale: The correct answer is B: 'Compromise.' In this scenario, Katherine is willing to engage with the staff member but suggests they postpone the discussion to a later time. This demonstrates a willingness to find a middle ground or reach a mutual agreement, which aligns with the concept of compromise. 'Smoothing' involves downplaying differences to maintain harmony, 'Avoidance' is ignoring or postponing the issue altogether, and 'Restriction' refers to limiting the interaction or communication. Therefore, 'Compromise' best fits the situation where Katherine is open to discussing the matter at a more suitable time.

2. He asserts the importance of promoting a positive organizational culture in their unit. Which

A. Proactive and caring with one another
B. Competitive and perfectionist
C. Powerful and oppositional
D. Obedient and uncomplaining

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.

3. What is the shape of the DNA molecule?

A. Linear
B. Circular
C. Double helix
D. Straight chain

Correct answer: C

Rationale: Rationale: The shape of the DNA molecule is a double helix. This structure was first described by James Watson and Francis Crick in 1953. The double helix shape consists of two strands that are twisted around each other in a spiral. This shape allows DNA to be compactly stored within the cell nucleus and provides stability to the molecule. The other options (A) Linear, (B) Circular, and (D) Straight chain do not accurately describe the shape of the DNA molecule.

4. Locate the heart within the human body cavities.

A. Dorsal cavity
B. Ventral cavity
C. Thoracic cavity
D. Abdominal cavity

Correct answer: C

Rationale: Rationale: The heart is located within the thoracic cavity, specifically in the mediastinum, which is the central compartment of the thoracic cavity. The thoracic cavity is part of the ventral cavity, which also includes the abdominal cavity. The dorsal cavity refers to the posterior side of the body and does not contain the heart. The heart is situated in the thoracic cavity between the lungs and above the diaphragm, making option C the correct choice.

5. Nervous tissue is responsible for

A. Movement
B. Protection
C. Communication and coordination
D. Nutrient transport

Correct answer: C

Rationale: Nervous tissue is responsible for communication and coordination within the body. This tissue includes neurons and supporting cells, which work together to transmit electrical signals and information throughout the body. Movement is primarily controlled by the muscular system, protection is the role of the immune system and skin, while nutrient transport is primarily handled by the circulatory system. Therefore, the correct answer is C: 'Communication and coordination.'

6. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both. Which of the following represents the LCM of 14 and 21?

A. 42
B. 63
C. 84
D. 168

Correct answer: C

Rationale: We can list out the multiples of each number until we find a common multiple. 14, 28, 42, 56, 84, ... 21, 42, 63, 84, ... The least common multiple is 84.
