1. Why do cicadas make a buzzing sound?

• A. To orient via echolocation
• B. To attract a mate
• C. To locate a food source
• D. To ward off predators

Correct answer: B

Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.

2. After an unexpected rearrangement of their schedules, Thomas and his sister realize that they will have to squeeze in the film after 10 p.m. Given this new information, which cinema is the best option?

• A. Twin Theatres
• B. Reveler Cinema
• C. Big Screen 14
• D. Best Seat in The House

Correct answer: B

Rationale: Since Thomas and his sister have to squeeze in the film after 10 p.m., they need to watch the film later in the evening. Among the options, Reveler Cinema offers showtimes after 10 p.m. with a showing at 7:15 p.m., making it the best choice. Twin Theatres, Big Screen 14, and Best Seat in The House do not have showtimes after 10 p.m., making Reveler Cinema the most suitable option for the siblings to catch a film at that time.

3. Julie Walker-Mayfield plans to register for fall classes at Chatham College. She works during the day and doesn't get off work until 5:30 PM. She also has no internet access at work and will have to register for classes once she gets home. Taking into account her personal schedule and the registration schedule provided by the college, when will she be able to go online to enter the registration system and select her classes?

• A. Monday, 10 AM-12 PM
• B. Monday, 5-7 PM
• C. Tuesday, 5-7 PM
• D. Tuesday, 8-10 PM

Correct answer: C

Rationale: Julie Walker-Mayfield doesn't get off work until 5:30 PM, so she won't be able to register for classes until she gets home. Considering she needs time to unwind after work and settle in, the earliest and most suitable time for her to enter the registration system and select her classes is Tuesday, 5-7 PM. Choice A is incorrect as it falls on Monday, and she gets off work at 5:30 PM. Choices B and D are also incorrect as she needs time to settle in after work before going online to register.

4. 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.

5. Which of the following best expresses the meaning of "intelligence (instinct)" in the context of this passage?

• A. Instinct is synonymous with intelligence in the passage.
• B. Intelligence and instinct are not clearly distinct in the context.
• C. Instinct is a natural ability to perform actions without learned behavior.
• D. Instinct refers to an animal's natural survival mechanism.

Correct answer: A

Rationale: Instinct refers to natural, unlearned behaviors, particularly in survival and reproduction.
