Question
(1) Fireflies dart and dive in the evening sky, captivating the imaginations of
young and old alike. (2) Like magic, these seemingly simple creatures create their
own light. (3) Through a chemical reaction, some insects and even sea creatures
glow, known as bioluminescence. (4) In fact, scientists estimate that up to 90% of
deep sea organisms make light through bioluminescence. (5) Though rarely seen
by humans, bioluminescence is extremely common in the depths of oceans and
seas around the world. (6) The chemical responsible for this feature is luciferin.
(7) When luciferin reacts with oxygen, it produces light. (8) When sea creatures
want to achieve particular purposes, they glow. (9) By controlling the release of the
chemicals in their bodies, they choose when and how to emit light. (10) The result is
magical!

2 In sentence 4, Alexis did not use the most appropriate word to explain what deep sea organisms do. Which of the following is the BEST replacement for the word make?
A cause
B whip up
C manufacture
D generate
3 Alexis would like to further develop the idea she presented in sentence 6. Which of these would be the BEST to add after sentence 6?
A The word luciferin is derived from the Latin word lucifer which means “light-bringer.”
B Many underwater organisms also produce luciferase, which acts as a catalyst to speed up the reaction that creates light.

Here are the recommended answers for each question based on clarity, effectiveness, and development of ideas:
1. **What is the MOST effective revision to make in sentence 3?**
- **Answer:** **A** Through a chemical reaction known as bioluminescence, some insects and even sea creatures glow.
- **Explanation:** This revision makes the sentence clearer by placing the crucial information about bioluminescence at the beginning, making it easier for readers to understand the relationship between the chemical reaction and the phenomena.
2. **Which of the following is the BEST replacement for the word make in sentence 4?**
- **Answer:** **D** generate
- **Explanation:** "Generate" is the most appropriate term in this context, as it implies the creation or production of light in a scientific way, matching the tone of the passage.
3. **Which of these would be the BEST to add after sentence 6?**
- **Answer:** **B** Many underwater organisms also produce luciferase, which acts as a catalyst to speed up the reaction that creates light.
- **Explanation:** This addition directly relates to luciferin and expands on the topic by introducing an additional relevant component (luciferase) that assists in the bioluminescence process, enriching the explanation.
4. **Which is the BEST revision to make in sentence 9?**
- **Answer:** **B** By producing light for particular purposes, underwater creatures can find a mate, attract prey, or confuse predators.
- **Explanation:** This revision maintains the original idea while varying sentence structure, providing a clearer list of purposes for light production, and enhances the flow of information.
