1. Which sentence uses the passive voice correctly?

• A. The letter was written by Mary.
• B. John built the house.
• C. She gave the flowers to him.
• D. They were eating dinner.

Correct answer: A

Rationale: Option a clearly identifies the object (letter) acted upon and the agent (Mary) performing the action in the passive voice.

2. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

• A. Advise her staff to go on vacation.
• B. Ignore her observations; it will be resolved even without intervention
• C. Remind her to show loyalty to the institution.
• D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.

3. Which of the following is a balanced chemical equation?

• A. H2 + O2 → H2O
• B. 2H2 + O2 → 2H2O
• C. 3H2O → 2H2 + O2
• D. H2O → H2 + O2

Correct answer: b

Rationale: The equation is balanced, with equal numbers of atoms of each element on both sides.

4. How are genetic markers used in paternity testing?

• A. They identify unique sequences in the father's DNA present in the child.
• B. They analyze the presence or absence of specific alleles for certain genes.
• C. They compare the child's blood type to the parents' blood types.
• D. They measure the child's physical resemblance to the father.

Correct answer: B

Rationale: Rationale: Genetic markers are specific DNA sequences that can vary among individuals. In paternity testing, genetic markers are used to compare the DNA of the child with that of the alleged father. By analyzing the presence or absence of specific alleles (different forms of a gene) at these genetic markers, scientists can determine the likelihood of paternity. This method is more accurate and reliable than comparing blood types or physical resemblance, making option B the most appropriate choice.

5. The innate immune system provides:

• A. Nonspecific, immediate defense against pathogens
• B. Specific, long-term immune response through memory cells
• C. Both (a) and (b)
• D. Neither (a) nor (b)

Correct answer: A

Rationale: The correct answer is A: 'Nonspecific, immediate defense against pathogens.' The innate immune system is the body's first line of defense against pathogens and provides a rapid, nonspecific response. It includes physical barriers like the skin, chemical barriers like stomach acid, and cellular responses like inflammation. This system does not involve memory cells or provide long-term immunity, which are characteristics of the adaptive immune system. Therefore, option A accurately describes the function of the innate immune system as a quick and nonspecific defense mechanism.

6. What is the strongest evidence for evolution?

• A. The fossil record
• B. Comparative anatomy
• C. Biogeography
• D. All of the above

Correct answer: D

Rationale: Rationale: A) The fossil record provides evidence of how organisms have changed over time, showing transitional forms and the progression of species. B) Comparative anatomy involves studying the similarities and differences in the structures of different species, which can reveal common ancestry and evolutionary relationships. C) Biogeography examines the distribution of species around the world, which can be explained by evolution and continental drift. By considering all of the above evidence together, scientists can build a comprehensive understanding of evolution and how species have changed and diversified over time.
