1. Which of the following is NOT a primary producer in an ecosystem?
- A. Grass
- B. Deer
- C. Algae
- D. Mushroom
Correct answer: B
Rationale: Rationale: - A) Grass: Grass is a primary producer because it can photosynthesize and convert sunlight into energy, making it the base of the food chain. - B) Deer: Deer are consumers that feed on primary producers like grass, so they are not primary producers themselves. - C) Algae: Algae are primary producers that can photosynthesize and produce energy from sunlight. - D) Mushroom: Mushrooms are decomposers that break down organic matter, so they are not primary producers.
2. What is the best way to punctuate the dialogue "Are you coming?" she asked. "Maybe," I replied.
- A. "Are you coming?" she asked? "Maybe," I replied.
- B. "Are you coming?" she asked. "Maybe," I replied.
- C. "Are you coming?" she asked, "Maybe," I replied.
- D. "Are you coming?" she asked, "Maybe," I replied.
Correct answer: B
Rationale: Each speaker's words need quotation marks, and the question mark should go inside the closing quotation mark of the question.
3. Which orbital can hold a maximum of 8 electrons?
- A. s orbital
- B. p orbital
- C. d orbital
- D. f orbital
Correct answer: C
Rationale: d orbital - Each d orbital can hold a maximum of 2 electrons, and there are 5 d orbitals, totaling 10 possible electrons.
4. In which medium does light propagate at its highest speed?
- A. Air
- B. Water
- C. Glass
- D. Diamond
Correct answer: A
Rationale: The correct answer is A: 'Air.' Light propagates at its highest speed in a vacuum, which is nearly the same as in air. In a vacuum, light travels at its maximum speed of approximately 299,792 kilometers per second. When light enters a medium like air, water, glass, or diamond, its speed decreases due to interactions with atoms and molecules in the medium. Among the options given, air is the closest medium to a vacuum in terms of light speed. Water, glass, and diamond have higher refractive indices than air, causing light to travel slower in these mediums. This is why air allows light to propagate at its highest speed compared to water, glass, and diamond.
5. Which pronoun correctly replaces the underlined phrase in the sentence: "Jessica invited Sarah and me to the party, but I forgot to respond to her."
- A. We
- B. Us
- C. Ours
- D. Myself
Correct answer: C
Rationale: "Ours" clarifies that the response forgetting was a joint action by Jessica and the speaker.
6. She conducts a 6-month performance review session with a staff member. Which of the
- A. She asks another nurse to attest the session as a witness.
- B. She informs the staff that she may ask another nurse to read the appraisal before the session is
- C. She tells the staff that the session is manager-centered.
- D. The session is private between the two members.
Correct answer: C
Rationale: Option C is the correct answer because telling the staff that the session is manager-centered indicates that the focus will be on the manager's evaluation and feedback rather than promoting a collaborative and transparent review process. This approach can lead to a one-sided assessment and may not foster open communication or growth opportunities for the staff member. Options A and B involve bringing in another nurse, which could potentially compromise the privacy and effectiveness of the performance review. Option D, stating that the session is private between the two members, does not address the issue of the session being manager-centered. Therefore, option C is the most appropriate choice to highlight the importance of a balanced and inclusive performance review process.
