1. 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.

2. Which of the following is true about calcium-rich foods? I. Canned salmon with bones contains calcium. II. Cheese is a lactose-free food. III. Condensed soup made with water is a calcium-rich food.

• A. I only
• B. I and II only
• C. II and III only
• D. III only

Correct answer: A

Rationale: The correct answer is 'I only.' Canned salmon with bones contains calcium as the bones are a good source of calcium, making statement I true. However, statement II is false as cheese is not a lactose-free food. Statement III is also incorrect as condensed soup made with water is not necessarily a calcium-rich food. Other calcium-rich options include dairy products like milk, yogurt, and specific non-dairy products like calcium-fortified juices, canned fish with bones, soybeans, and leafy greens.

3. Which of the following can the reader infer about the author's point of view when they state: 'the work Lamarr and Antheil did creating this frequency-hopping system led to many technologies that are often taken for granted today?'

• A. The author believes that we have underestimated the value of the contributions of lesser-known inventors
• B. The author believes that the frequency-hopping system has damaged the potential of modern electronics
• C. The author believes that the work of Lamarr and Antheil was instrumental to victory in World War II
• D. The author believes we spend too much time using technologies derived from...

Correct answer: A

Rationale: The author highlights the significance of the contributions made by lesser-known inventors like Lamarr and Antheil.

4. What would this author's attitude likely be towards a person unable to find employment?

• A. Descriptive
• B. Conciliatory
• C. Ingenuous
• D. Incredulous

Correct answer: D

Rationale: The author's likely attitude towards a person unable to find employment would be incredulous. The passage emphasizes the abundance of job opportunities in the United States and suggests that finding employment should not be difficult for those willing to work. The author believes that with the numerous avenues of success and available vocations, anyone who is willing to engage in a respectable occupation should be able to find lucrative employment. Therefore, the author would find it hard to believe or be skeptical towards someone who claims they cannot find a job. Choice A, 'Descriptive,' is incorrect as the author's attitude is more judgmental than just describing a situation. Choice B, 'Conciliatory,' is incorrect as the author does not show any intention to reconcile or make peace with the situation of unemployment. Choice C, 'Ingenuous,' is incorrect as this term means innocent or naive, which does not align with the author's likely attitude of disbelief towards unemployment.

5. Which of the following bones is not part of the appendicular skeleton?

• A. skull
• B. clavicle
• C. scapula
• D. pelvic bone

Correct answer: A

Rationale: The correct answer is A, 'skull.' The skull is part of the axial skeleton, not the appendicular skeleton. The axial skeleton, which includes the skull, vertebrae, and ribs, is located down the center of the body and protects vital organs such as the brain and heart. On the other hand, the appendicular skeleton consists of bones of the arms, legs, and the bones that attach these limbs to the axial skeleton. Choices B, C, and D (clavicle, scapula, pelvic bone) are part of the appendicular skeleton as they form the bones of the limbs and girdles that connect the limbs to the axial skeleton.
