1. What was one of Hedy Lamarr's notable inventions?

• A. Improved traffic light
• B. Carbonated drink
• C. Radio-controlled torpedoes
• D. Frequency-hopping system

Correct answer: D

Rationale: One of Hedy Lamarr's notable inventions was the frequency-hopping system, which she developed during World War II to secure radio-controlled torpedoes. This system changed frequencies to prevent jamming by enemies. Lamarr's frequency-hopping technology laid the groundwork for modern technologies like cell phones, Bluetooth, and WiFi. Choices A and B are mentioned as some of Lamarr's failed inventions in the passage. Choice C refers to the military technology that inspired Lamarr's invention, not her invention itself.

2. What role do the spiracles play in the respiration of the insects described in the passage?

• A. They allow insects to breathe atmospheric air even when submerged.
• B. They protect the insect's internal organs from water pressure.
• C. They filter oxygen from the water for underwater breathing.
• D. They are used to expel carbon dioxide from the body.

Correct answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

3. What should be done after the soil has been loosened with a tiller or trowel?

• A. Mix fertilizer or compost into loosened soil.
• B. Dig a 4-inch-deep trench.
• C. Cut potatoes into pieces.
• D. Mound soil around the base of the plant.

Correct answer: A

Rationale: After the soil has been loosened with a tiller or trowel, the next step should be to mix fertilizer or compost into the loosened soil. This action is crucial as it provides essential nutrients for plant growth, improves soil fertility, and promotes healthy plant development. Digging a trench, cutting potatoes, or mounding soil around the base of the plant are not tasks typically performed immediately after loosening the soil. Therefore, option A is the correct choice as it aligns with the standard practice of enhancing soil quality before planting.

4. According to the table above, how many more shirts were ordered in size medium than size small in the month of January?

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: B

Rationale: The corrected question asks how many more shirts were ordered in size medium than in size small in January. The table shows that two more shirts were ordered in size medium than in size small. Therefore, the correct answer is 'Two.' Choice A, 'One,' is incorrect as the comparison is between medium and small, not medium and large. Choices C and D, 'Three' and 'Four,' are incorrect as the actual difference is two as per the data provided in the table.

5. Which definition most closely relates to the usage of the word 'moult' in the passage?

• A. An adventure of sorts, especially underwater
• B. Mating act between two insects
• C. The act of shedding part or all of the outer shell
• D. Death of an organism that ends in a revival of life

Correct answer: C

Rationale: 'Moult' refers to the act of shedding the outer shell, which is part of the insect's development. In the passage, it mentions insects that remain continually under water until they are ready to undergo their final moult and attain the winged state. This process of shedding the outer shell is crucial for insects transitioning from their aquatic larval stage to their aerial adult stage. Choices A, B, and D do not align with the specific context provided in the passage about the term 'moult.'
